| i make two list theme
1. the posts have featured image and title, but empty content. i want get this list.

this code doesn't work, Please give me some detailed code, thanks | Try using **get\_post\_ancestors**. Here is how you can apply this in your case:
```
<?php
global $wp_query;
$post = $wp_query->post;
$ancestors = get_post_ancestors($post);
if( empty($post->post_parent) ) {
$parent = $post->ID;
} else {
$parent = end($ancestors);
}
if(wp_list_pages("title_li=&child_of=$parent&echo=0" )) {
wp_list_pages("title_li=&child_of=$parent&depth=1" );
}
?>
```
You'll probably need to remove the depth parameters to show you're 3rd level pages.

My media settings are 150x150px on thumbnails, but now `the_post_thumbnail()` will output a full sized image instead. Why?
I see that the only way to have `the_post_thumbnail()` to really output the thumbnail size is to explicitly pass it:
`the_post_thumbnail('thumbnail')`
Why? | I think adding support to 'post-thumbnails' also adds a new type of size: 'post-thumbnail'. But 'post-thumbnail' **is not** == 'thumb' or 'thumbnail', it's a new, different type.
Also, `the_post_thumbnail()` if called without params will output the 'post-thumbnail' size instead of the 'thumb' size.
'thumb' (or 'thumbnail') are setted via admin media panel, while 'post-thumbnail' is not.
Since the 'post-thumbnail' size is not yet setted, than `the_post_thumbnail()` doesn't really know what size to use, and thus it will output the full image.
To set the 'post-thumbnail' size you must use standard `add-image-size()` passing 'post-thumbnail' as the name, or, just use `set_post_thumbnail_size()`. |

| I am trying to work out a submit contact form through ajax but somehow i fail in process and i can't figure out, every combination i try it returns `0` for some reason.
This is my form
```
<form name="sentMessage" id="contactForm" novalidate>
<div class="form-group wow fadeInUp">
<input type="text" class="form-control" placeholder="Your Name *" id="name" name="name" required data-validation-required-message="Please enter your name.">
<p class="help-block text-danger"></p>
</div>
<div class="form-group wow fadeInUp">
<input type="email" class="form-control" placeholder="Your Email *" id="email" name="email" required data-validation-required-message="Please enter your email address.">
<p class="help-block text-danger"></p>
</div>
<div class="form-group wow fadeInUp">
<textarea class="form-control" placeholder="Your Message *" id="message" name="message" required data-validation-required-message="Please enter a message."></textarea>
<p class="help-block text-danger"></p>
</div>
<div class="clearfix"></div>
<div class="col-lg-12 wow fadeInUp">
<div id="success"></div>
<button type="submit" class="btn btn-danger btn-lg">Send Message</button>
</div>
</form>
```
And this is the ajax script in included.
```
$("input,textarea").jqBootstrapValidation({
preventSubmit: true,
submitError: function($form, event, errors) {
// additional error messages or events
},
submitSuccess: function($form, event) {
event.preventDefault(); // prevent default submit behaviour
// get values from FORM
var name = $("input#name").val();
var email = $("input#email").val();
var message = $("textarea#message").val();
var firstName = name; // For Success/Failure Message
// Check for white space in name for Success/Fail message
console.log(name + email + message);
if (firstName.indexOf(' ') >= 0) {
firstName = name.split(' ').slice(0, -1).join(' ');
}
var data = $form.serialize();
console.log(data);
$.ajax({
url: ajax_contact.ajaxurl,
dataType: 'json',
action: 'ajax_contact',
data: ajax_contact.data,
cache: false,
success: function(data) {
console.log(data);
if(data.status == "success") {
// Success message
$('#success').html("<div class='alert alert-success'>");
$('#success > .alert-success').html("<button type='button' class='close' data-dismiss='alert' aria-hidden='true'>×").append("</button>");
$('#success > .alert-success').append("<strong>" + data.message + "</strong>");
$('#success > .alert-success').append('</div>');
//clear all fields
$('#contactForm').trigger("reset");
}
if(data.status == "error") {
// Error message
$('#success').html("<div class='alert alert-danger'>");
$('#success > .alert-danger').html("<button type='button' class='close' data-dismiss='alert' aria-hidden='true'>×").append("</button>");
$('#success > .alert-danger').append("<strong>" + data.message + "</strong>");
$('#success > .alert-danger').append('</div>');
//clear all fields
$('#contactForm').trigger("reset");
}
},
error: function() {
// Fail message
$('#success').html("<div class='alert alert-danger'>");
$('#success > .alert-danger').html("<button type='button' class='close' data-dismiss='alert' aria-hidden='true'>×").append("</button>");
$('#success > .alert-danger').append("<strong>Sorry " + firstName + ", it seems that my mail server is not responding. Please try again later!");
$('#success > .alert-danger').append('</div>');
//clear all fields
$('#contactForm').trigger("reset");
},
})
},
filter: function() {
return $(this).is(":visible");
},
});
```
And i properly added to functions.php
```
function ajax_contact() {
try {
if (empty($_POST['name']) || empty($_POST['email']) || empty($_POST['message'])) {
throw new Exception('Bad form parameters. Check the markup to make sure you are naming the inputs correctly.');
}
if (!is_email($_POST['email'])) {
throw new Exception('Email address not formatted correctly.');
}
$website_email = !empty(get_theme_option('contact_email')) ? get_theme_option('contact_email') : get_bloginfo('admin_email');
$subject = 'Website Contact Form from: '.$_POST['name'];
$headers = 'From: '.get_bloginfo('name').' Contact Form ' .$website_email;
$send_to = $website_email;
$subject = get_bloginfo('name') . " Contact Form: " .$_POST['name'];
$message = "You have received a new message from your website contact form.\n\n"."Here are the details:\n\nName: " . $_POST['name'] . "\n\nEmail: " . $_POST['email'] . "\n\nMessage:\n". $_POST['message'] . "";
if (wp_mail($send_to, $subject, $message, $headers)) {
echo json_encode(array('status' => 'success', 'message' => 'Contact message sent.'));
exit;
} else {
throw new Exception('Failed to send email. Check AJAX handler.');
}
} catch (Exception $e) {
echo json_encode(array('status' => 'error', 'message' => $e->getMessage()));
exit;
}
die();
}
add_action( 'wp_ajax_ajax_contact', 'ajax_contact' );
add_action( 'wp_ajax_nopriv_ajax_contact', 'ajax_contact' );
function ajax_contact_js() {
wp_localize_script('ajax-contact', 'ajax_contact', array('ajaxurl' => admin_url('admin-ajax.php')));
}
add_action('wp_enqueue_scripts', 'ajax_contact_js');
```
And i also enqueued all the scripts that needed in separate function, so i don't get any errors and seems that everything is included and properly added but in function it fails somehow and i always get response 0. | At the end i made it working like this.
```
<form name="sentMessage" id="contactForm" method="post" action="<?php echo admin_url('admin-ajax.php'); ?>" role="form" data-toggle="validator">
<div class="form-group wow fadeInUp">
<input type="text" class="form-control" placeholder="Your Name *" id="name" name="name" required data-error="Please enter your name.">
<div class="help-block with-errors text-danger"></div>
</div>
<div class="form-group wow fadeInUp">
<input type="email" class="form-control" placeholder="Your Email *" id="email" name="email" required data-error="Please enter your email address.">
<div class="help-block with-errors text-danger"></div>
</div>
<div class="form-group wow fadeInUp">
<textarea class="form-control" placeholder="Your Message *" id="message" name="message" required data-error="Please enter a message."></textarea>
<div class="help-block with-errors text-danger"></div>
</div>
<div class="clearfix"></div>
<div class="col-lg-12 wow fadeInUp">
<div id="success"></div>
<input type="hidden" name="action" value="ajax_contact" />
<?php wp_nonce_field( 'contact_nonce', 'contact_nonce' ); ?>
<button type="submit" class="btn btn-danger btn-lg">Send Message</button>
</div>
</form>
```
As you can see on the form i added `method` to `post` and `action` to `wordpress ajax url`
I also added hidden field with value to registered action hook and nonce field.
And in javascript file i changed to this
```
$('#contactForm').on('submit', function(e) {
e.preventDefault();
var $form = $(this);
$.post( $form.attr('action'), $form.serialize(), 'json')
.done(function( data ) {
var response = JSON.parse(data);
if(response.status == "success") {
// Success message
$('#success').html("<div class='alert alert-success'>");
$('#success > .alert-success').html("<button type='button' class='close' data-dismiss='alert' aria-hidden='true'>×").append("</button>");
$('#success > .alert-success').append("<strong>" + response.message + "</strong>");
$('#success > .alert-success').append('</div>');
//clear all fields
$('#contactForm').trigger("reset");
} else if(response.status == "error") {
// Error message
$('#success').html("<div class='alert alert-danger'>");
$('#success > .alert-danger').html("<button type='button' class='close' data-dismiss='alert' aria-hidden='true'>×").append("</button>");
$('#success > .alert-danger').append("<strong>" + response.message + "</strong>");
$('#success > .alert-danger').append('</div>');
//clear all fields
$('#contactForm').trigger("reset");
} else {
// Fail message
$('#success').html("<div class='alert alert-danger'>");
$('#success > .alert-danger').html("<button type='button' class='close' data-dismiss='alert' aria-hidden='true'>×").append("</button>");
$('#success > .alert-danger').append("<strong>Sorry " + firstName + ", it seems that my mail server is not responding. Please try again later!");
$('#success > .alert-danger').append('</div>');
//clear all fields
$('#contactForm').trigger("reset");
}
})
.fail(function() {
// Fail message
$('#success').html("<div class='alert alert-danger'>");
$('#success > .alert-danger').html("<button type='button' class='close' data-dismiss='alert' aria-hidden='true'>×").append("</button>");
$('#success > .alert-danger').append("<strong>Sorry " + firstName + ", it seems that my mail server is not responding. Please try again later!");
$('#success > .alert-danger').append('</div>');
//clear all fields
$('#contactForm').trigger("reset");
});
```
The most important part was `JSON.parse`
And function and registered hooks in .php file remain unchanged, only thing i added was check for nonce field. |

If ($description_box is true) {

How to correctly write this using this →<https://codex.wordpress.org/Function_Reference/checked>
Update →
I tried using this →
```
<?php if($description_box==0){ ?>
<p><</p>
<?php } ?>
```
But the problem is if the widget is in 2 different sidebars, in one checkbox ticked and in another not, but the result is same in both i.e. it either displays `<p></p>` or not based on the either `$description_box` is set to 0/1 or true/false in the `php` `if condition`. whats the remedy? | Now, based on your full code, there's 3 problems:
Line 60 of your code is missing a semi colon and throwing a fatal error. So:
```
$instance['description_check_box'] = $new_instance['description_check_box']
```
Should be:
```
$instance['description_check_box'] = $new_instance['description_check_box'];
```
On line 66, you're using strings instead of proper boolean `true` or `false` values. Both if these are 'truthy' (see [this answer](https://stackoverflow.com/a/6693908/2684861) to another question for what that means), so will both resolve as `true` if used in an if statement. `if ('false')` is `true`. So:
```
$description_check_box = $instance[ 'description_check_box' ] ? 'true' : 'false';
```
Should be:
```
$description_check_box = $instance[ 'description_check_box' ] ? true : false;
```
On line 121 you haven't got `on` in quotes, so you're comparing `$description_check_box` to the *constant* `on`. This should be in quotes if you want to check if the value of `$description_check_box` is `on`. So:
```
<?php if($description_check_box==on){ ?>
```
Should be:
```
<?php if($description_check_box=='on'){ ?>
```
BUT. This still won't work. Because you'd be setting `$description_check_box` to `true` or `false` based on whether it's checked on line 66, but later you're checking if the value is `'on'`.
You either need to set the value of `$description_check_box` to `'on'`, or change your comparison to checking if `$description_check_box` is `true`.
You should also use `isset()` before using `$instance['description_check_box']`, because otherwise you'll get an undefined index notice in the customiser when WP\_Debug is enabled.

```
width="600" height="450"
```
So, map show up in a very small size, about 200px X 100px | Now, based on your full code, there's 3 problems:
Line 60 of your code is missing a semi colon and throwing a fatal error. So:
```
$instance['description_check_box'] = $new_instance['description_check_box']
```
Should be:
```
$instance['description_check_box'] = $new_instance['description_check_box'];
```
On line 66, you're using strings instead of proper boolean `true` or `false` values. Both if these are 'truthy' (see [this answer](https://stackoverflow.com/a/6693908/2684861) to another question for what that means), so will both resolve as `true` if used in an if statement. `if ('false')` is `true`. So:
```
$description_check_box = $instance[ 'description_check_box' ] ? 'true' : 'false';
```
Should be:
```
$description_check_box = $instance[ 'description_check_box' ] ? true : false;
```
On line 121 you haven't got `on` in quotes, so you're comparing `$description_check_box` to the *constant* `on`. This should be in quotes if you want to check if the value of `$description_check_box` is `on`. So:
```
<?php if($description_check_box==on){ ?>
```
Should be:
```
<?php if($description_check_box=='on'){ ?>
```
BUT. This still won't work. Because you'd be setting `$description_check_box` to `true` or `false` based on whether it's checked on line 66, but later you're checking if the value is `'on'`.
You either need to set the value of `$description_check_box` to `'on'`, or change your comparison to checking if `$description_check_box` is `true`.
You should also use `isset()` before using `$instance['description_check_box']`, because otherwise you'll get an undefined index notice in the customiser when WP\_Debug is enabled.

How can i solve this problem? | This issue generally occurs when php script takes more time for execution than set in php.ini file
You can resolve this issue by using two methods:
Method 1: Editing .htaccess File Manually
Put **php\_value max\_execution\_time 600** in .htaccess file 600 is the value of execution time in seconds, you can use yours value, the maximum value is better.
Method 2: You can use <https://wordpress.org/plugins/wp-maximum-execution-time-exceeded/> plugin to maximise the execution tome |

| I need to have a hidden custom field that will be automatically populated with the title of the post on save.
My goal is to query posts by all its meta fields, including the title, but from my research I learned that it's not easily possible to combine title and meta\_query.
What should be the script for creating this hidden field as meta? | This will automatically update a meta named `post_title` to the value of the post's title, no matter where you save the post from:
```
function wpse_275785_save_title_as_meta( $post_id, $post, $update ) {
update_post_meta( $post_id, 'post_title', $post->post_title );
}
add_action( 'save_post', 'wpse_275785_save_title_as_meta', 99, 3 );

| I have the following code in my main plugin file
```
<?php
include plugin_dir_path( __FILE__) . 'options.php';
include plugin_dir_path( __FILE__ ) . 'config.php';
include plugin_dir_path( __FILE__ ) . 'front/manage.php';
add_action( 'admin_init', 'restrict_admin', 1 );
//prepare wordpress for ajax this needs to be done early to avoid strange race conditions
add_action( 'wp_ajax_devices', 'api_list_devices' );
add_action( 'wp_ajax_profiles', 'api_list_profiles' );

add_action( 'wp_ajax_set_profile', 'api_set_profiles' );
define('AJAX_NONCE_NAME',"title_example");
//...
```
I assume since adding an action just lets admin-ajax.php know it should run some action at some point later, my includes aren't even executed, but I need them to authenticate the database connection. How can I tell wordpress to do my includes for parts of wordpress like this that are beyond my control? Do I have to enqueue, all the enqueueing examples seem to apply to the front end? | "...I need them to authenticate the database connection."
Not exactly sure this is what you want, but in your ajax function you can connect to and use a database if you [declare the global variable $wpdb](https://codex.wordpress.org/Class_Reference/wpdb).
Here's a simple example:
```
function api_list_devices() {
global $wpdb;
$name = $_POST['name']; // ajax call sends "name"
// try to insert $name into "people" tables "name" column
if($wpdb->insert('people',array(
'name'=>$name
))===FALSE){
echo "Error";
}
else {
echo "Person '".$name. "' has been successfully added;
}
}

275,907 | <p>I've created a plugin using various classes. I want to be able to access the methods on several of the different classes from within the page templates of my custom theme. The method I'm currently using is to make static methods but I'm wondering if this is the best way to do it?</p>
<p>An example could be a class with a method that checks whether the user is logged in and what their user role is. Let's call the class <code>Plugin_Access</code> and the method <code>has_access()</code>;</p>
<p>Now let's say I need to customize content in the header, page template and footer using if() statements based on <code>has_access()</code>. To do this I would use <code>if( Plugin_Access::has_access() )</code>. To me I feel like this isn't the cleanest solution. I'm essentially calling the same method and getting the same result 3 times. If it had a call to the database within the method, this would be 3 calls rather than 1.</p>
<p>One solution I thought of was to make the class a <code>singleton</code> and to store the result of the function in a variable within the class. Then the method would check this variable and if it's <code>null</code>, then complete the rest of the method, otherwise just return the stored variable.</p>
<p>I feel like I'm definitely missing something. Thanks in advanced for any advice.</p>

``` | The names of unchecked boxes in `Screen Options` for `Edit Post` screen are stored in user's meta, per individual user, as an array. Insert the following code in your theme's `functions.php`:
```
function wpse_edit_post_show_excerpt( $user_login, $user ) {
$unchecked = get_user_meta( $user->ID, 'metaboxhidden_post', true );
$key = array_search( 'postexcerpt', $unchecked );
if ( FALSE !== $key ) {
array_splice( $unchecked, $key, 1 );
update_user_meta( $user->ID, 'metaboxhidden_post', $unchecked );
}
}
add_action( 'wp_login', 'wpse_edit_post_show_excerpt', 10, 2 );
```
This will update user's meta ( after successful login ) by removing `postexcerpt` name from the array of unchecked boxes names.

| I'm using ACF to build some custom elements on pages and also WPML to manage the translations of these pages.
I am currently seeing an issue where the pages do not save when I update the language content.
In the WPML custom field settings I have each custom field down to the Translate option.
Within each page I am copying the content to a language to pre-populate the custom fields and not use the synchronise option as I want to translate this independently.
Any ideas as to why my content is not saving and reverting back to the original?
Thanks | I've had a fair share of issues with ACF, but end up using it still.
There could be 3 things causing your problem.
you could try changing your php settings:
```
max_input_time = 42000
max_execution_time = 42000
max_input_vars = 50000
```
This next one is not a great fix as if WordPress ever decides to update their tables it could cause problems (but that hasn't happened yet):
wp\_options table, option\_name column -> increase length from 64 to something else, like 255
More painfully you need to shorten your field names. If you're using something like my\_super\_cool\_extra\_amazing\_language\_field, acf starts taking a lot memory. Shorten all field names.
This is all of course assuming you're not using any special functions to save the field as i wouldn't be able to test those with out seeing them. |

| So I'm attempting to create a single page Wordpress theme and right now I'm using my index.php as the page they will initially see.
In my index.php I use The Loop to create a bunch of `a` tags that link to the all of the post permalinks.
What is the template file that I need to make or what do I need to define so that I can control what those posts look like once you travel to their permalink? | You can create new template php file.
```
//Template Name : Single Page Template
get_header();
if ( have_posts() ) :
while ( have_posts() ) : the_post();
the_content();
the_permalink();//this is for the <a> bunch you are looking for
endwhile;
endif;
get_footer();
```
Here , you can use "//" or "/\*\* \*\*/" to set the Template name , it varies from the theme you are using.
and then , go to Add New Page and there on the right sidebar , you can choose this template , by default it was set "Default Template".
There on dropdown , you can find the newly created template file named "Single Page Template". |

Thank you for all direction. | I would consider making it more flexible by **marking** the pages in question with post meta or custom taxonomy. That way you don't need to change a PHP code to choose what pages should have some custom look.
Here's an example, if we mark the pages with the `wpse-layout` custom field with the value `1` (assuming there could be more layout options):
```
add_filter( 'body_class', function( $classes )
{
// Only target pages
if( ! is_page() )
return $classes;
// Get the 'wpse_layout' post meta value for the current page
$layout = get_post_meta( get_queried_object_id(), 'wpse_layout', true );
if( empty( $layout ) )
return $classes;
// Inject the 'wpse-layout-1' body class,
// if the custom field 'wpse-layout' has the value 1
$classes[] = sprintf( 'wpse-layout-%d', $layout );
return $classes;
} );
```
This could be further adjusted in various ways, e.g. with some custom UI. |

| Having read elsewhere on Stack of two WP plugins forcing identical menu positions (with the likelihood of one then not appearing), I'm wondering how I can control the position of menu items added by plugins.
I already use a function which seems to handle such submenu items in 'settings', and another function to reorder default (posts, pages, themes, plugins, settings, etcetera) 'top level' items - but which doesn't change the positioning of such items added by plugins.
```
function custom_menu_order() {
return array(
//Add items here in desired order.
);
}
add_filter( 'custom_menu_order', '__return_true' );
add_filter( 'menu_order', 'custom_menu_order' );
```
As an example, of the two top-level menu items added by WooCommerce, one appears above the item added by ContactForm7 and the other below, and it'd be nice to reorder them accordingly - and also, to be able to better reorder items which don't force a menu position and instead appear at the bottom.
I find it usually works fine for re-ordering default and 'edit.php?post\_type=...' items, but those with 'admin.php?page=...' don't re-order.
When my re-order function is disabled, the two WooCommerce items ('edit.php?post\_type=product', and 'edit.php?post\_type=shop\_order') group together as intended, but when the function is reactivated they're split by ContactForm7 ('admin.php?page=wpcf7').
And, one ('edit.php?post\_type=shop\_order') of the WooCommerce CPTs won't reorder - although the other ('edit.php?post\_type=product') does. | To change top level admin menu items order you'll need two `hooks`, two `filters`, and one `function`. Put the following code in your current theme's `functions.php`:
```
function wpse_custom_menu_order( $menu_ord ) {
if ( !$menu_ord ) return true;
return array(
'index.php', // Dashboard
'separator1', // First separator
'edit.php', // Posts
'upload.php', // Media
'link-manager.php', // Links
'edit-comments.php', // Comments
'edit.php?post_type=page', // Pages
'separator2', // Second separator
'themes.php', // Appearance
'plugins.php', // Plugins
'users.php', // Users
'tools.php', // Tools
'options-general.php', // Settings
'separator-last', // Last separator
);
}
add_filter( 'custom_menu_order', 'wpse_custom_menu_order', 10, 1 );
add_filter( 'menu_order', 'wpse_custom_menu_order', 10, 1 );
```
The returned array of top level admin menu items, above, represents menu items inserted by core, in their default order. To include menu items added by plugins, we have to add them to this array. Let's say we have two plugins added and activated ( for example: `Wordfence` and `NextCellent Gallery` ). We have to find names of these menu items, first. When we click on `Wordfence`'s top level menu item, the resulting URL will end with `?page=Wordfence`. The part after `?page=` is our name ( `Wordfence` ). For `NextCellent Gallery`, the name will be `nextcellent-gallery-nextgen-legacy`. Now, let's add these items to our array:
```
return array(
'index.php', // Dashboard
'separator1', // First separator
'edit.php', // Posts
'upload.php', // Media
'link-manager.php', // Links
'edit-comments.php', // Comments
'edit.php?post_type=page', // Pages
'separator2', // Second separator
'themes.php', // Appearance
'plugins.php', // Plugins
'users.php', // Users
'tools.php', // Tools
'separator3', // Third separator
'options-general.php', // Settings
'separator-last', // Last separator
'Wordfence', // Wordfence
'nextcellent-gallery-nextgen-legacy', // NextCellent Gallery
);
```
We can, now, move items of this array, up and down, to get the final order.
**Note**: you can use [Admin Menu Editor](https://wordpress.org/plugins/admin-menu-editor/) plugin, for easy drag and drop actions, as well. |
276,232 | <p>My child theme customizer is not working. I have created a child theme from the parent theme called flash. In the parent theme I can use the customizer just fine and change the layout ect. However, when I activate my child theme nothing in in my customizer working in terms of layout.I feel like the issue lies in my style.css comment. I have researched this and everyone kept saying that it had to do with plugins so I deactivated and activated those one by one and nothing was wrong. So I think it has to do with how I am linking the child theme. I am new to child themes so maybe I'm way off by thinking it has anything to do with the style.css comment, but if someone has any idea why please let me know.</p>

It appears to be that way. `data-term` and `data` aren't the same attribute after all, and poking around in core I don't think any sort of regular expressions can be used as supported attributes.
You shouldn't need to run `wp_kses()` on your own markup though, you should know it's safe. `wp_kses()` is generally just for handling untrusted input from users. Are users going to be submitting data- attributes, and you need to support them all?
You could do something like this instead:
```
$my_var = '<div class="my-class" data-term="' . esc_attr( $term_id ) . '">' . wp_kses_post( $content ) . '</div>';
```
That uses `wp_kses_post()` which will use the default allowed html for posts, but it's only going to apply to whatever `$content` is. |

276,476 | <p>I am trying to develop a plugin for basic SEO purposes, as a lot of people I know don't like using Yoast.

It's used the same way as <code>plugins_url</code>, so you need the value of <code>__FILE__</code>, specifically its value in the root plugin file with your plugin header.</p>\n\n<p>The second parameter is a callable and works as you expect, but it's really just using <code>add_action</code> internally</p>\n\n<blockquote>\n <p>When a plugin is activated, the action ‘activate_PLUGINNAME’ hook is called. In the name of this hook, PLUGINNAME is replaced with the name of the plugin, including the optional subdirectory. For example, when the plugin is located in wp-content/plugins/sampleplugin/sample.php, then the name of this hook will become ‘activate_sampleplugin/sample.php’.</p>\n</blockquote>\n\n<h2>Part 2: Bootstrapping and <code>__FILE__</code></h2>\n\n<p>A fundamental problem here is that <code>__FILE__</code> will have different values in different locations, and you need a specific value.</p>\n\n<p>You also have a problem, that bootstrapping should assemble the object graph, but you don't do that. All your objects are created as soon as they're defined, or created inside eachother, making it difficult or impossible to pass values to them.</p>\n\n<p>As an example, I could write a plugin like this:</p>\n\n<p><code>plugin.php</code>:</p>\n\n<pre><code><?php\n/**\n * Plugin Name: My Plugin\n * Version: 0.1\n */\n\n// loading step\nrequire_once( 'php/app.php' );\n\n// bootstrapping step\n$app = new App( __FILE__ );\n\n// execution step\n$app->run();\n</code></pre>\n\n<p>I defined all my classes in the <code>php</code> subfolder, and loaded them all in the same place. PHP now knows what my classes are, their names etc, but nothing has happened yet.</p>\n\n<p>I then create all my objects, passing them what they need, in this case App needs the value of <code>__FILE__</code> so I pass it along. Note that this creates the objects in memory, but doesn't do any work. The plugins application is ready to go, to pounce into action, but it's in the preparation phase.</p>\n\n<p>The next step may be to pipe these objects into a set of unit tests, but now I'm going to run them. I've finished my bootstrapping process, and the application is ready to run, so I trigger the <code>run</code> method. I shouldn't need to pass anything to <code>run</code> as everything necessary has been passed to the constructors. During the <code>run</code> method, I add all my filters and hooks. It's during those hooks that all the other parts of the plugin run.</p>\n\n<p>The important part though is that I have a defined structure, and that I pass in what's necessary during the construction/bootstrapping phase, with a defined life cycle</p>\n"

The first parameter, `$file` is the main plugin file, not the file that contains what you want to run. It's used the same way as `plugins_url`, so you need the value of `__FILE__`, specifically its value in the root plugin file with your plugin header.
The second parameter is a callable and works as you expect, but it's really just using `add_action` internally

> When a plugin is activated, the action ‘activate\_PLUGINNAME’ hook is called. In the name of this hook, PLUGINNAME is replaced with the name of the plugin, including the optional subdirectory. For example, when the plugin is located in wp-content/plugins/sampleplugin/sample.php, then the name of this hook will become ‘activate\_sampleplugin/sample.php’.

Part 2: Bootstrapping and `__FILE__`
------------------------------------
A fundamental problem here is that `__FILE__` will have different values in different locations, and you need a specific value.
You also have a problem, that bootstrapping should assemble the object graph, but you don't do that. All your objects are created as soon as they're defined, or created inside eachother, making it difficult or impossible to pass values to them.
As an example, I could write a plugin like this:
`plugin.php`:
```
<?php
/**
* Plugin Name: My Plugin
* Version: 0.1
*/
// loading step
require_once( 'php/app.php' );
// bootstrapping step
$app = new App( __FILE__ );
// execution step
$app->run();
```
I defined all my classes in the `php` subfolder, and loaded them all in the same place. PHP now knows what my classes are, their names etc, but nothing has happened yet.
I then create all my objects, passing them what they need, in this case App needs the value of `__FILE__` so I pass it along. Note that this creates the objects in memory, but doesn't do any work. The plugins application is ready to go, to pounce into action, but it's in the preparation phase.
The next step may be to pipe these objects into a set of unit tests, but now I'm going to run them. I've finished my bootstrapping process, and the application is ready to run, so I trigger the `run` method. I shouldn't need to pass anything to `run` as everything necessary has been passed to the constructors. During the `run` method, I add all my filters and hooks. It's during those hooks that all the other parts of the plugin run.
The important part though is that I have a defined structure, and that I pass in what's necessary during the construction/bootstrapping phase, with a defined life cycle |

276,507 | <p>I have an extremely frustrating problem where mobile (tested chrome on android & ios, and safari on ios) is always using the largest sized image from the srcset (even if a smaller size is EXPLICITLY chosen in the editor).</p>
<p>Here is a summary of the problem:</p>
<ul>
<li>In Wordpress editor, when inserting an image, I choose LARGE (720px x 480px) as the image size</li>
<li>On a mobile device, the full size image from the srcset is being downloaded and shown on the frontend every time</li>
</ul>
<p>So the problem is two-fold:</p>
<ol>
<li>Firstly that the full image is somehow being used DESPITE actively selecting the large size (why should this be possible?)</li>
<li>Secondly that chrome is not respecting the src set anyway and is downloading the full sized image</li>
</ol>
<p>This is problematic because I purposefully generate many different image sizes as the original images for this blog are often quite large, often a couple of megabytes. So I have a post with 30 images, each with an elaborate srcset, and yet Chrome on Android is downloading the 1.5Mb version for every one (that's 45Mbs on mobile, even though there are images sizes and a srcset -- and a lightbox and lazy-loading which I've disabled for testing -- for this exact reason).</p>
<p>The image below is a screenshot from Chrome inspector using remote USB debugging (so this is actually from a phone, not browser simulation). You can see the image's actual SRC attribute is the correct, smaller version of the image (notice the '-720x480'):</p>

<p><a href="https://i.stack.imgur.com/2d3Xp.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/2d3Xp.jpg" alt="enter image description here"></a></p>
<p>However, Chrome on Android has in fact downloaded and is serving the full image. I know this because:</p>
<ol>
<li>Images in network tab show status of 200 (not from cache), and are the full sized images</li>
</ol>
<p><a href="https://i.stack.imgur.com/ySxlK.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ySxlK.jpg" alt="enter image description here"></a></p>
<ol start="2">
<li>The image (and post) takes a while to load (I can see the images downloading progressively)</li>
<li>Pressing and holding to download the image on the phone saves the full image</li>
<li>Pressing and opening the image in a new tab opens the full size image</li>
</ol>
<p>Some other things:</p>
<ul>
<li>It is correctly only downloading the smaller image on desktop (firefox & chrome)</li>
<li>On every test I fully clear the cache</li>
<li>The problem still occurs if LINK TO is set to NONE (to rule out the parent <code>a</code> tag's <code>href</code> interfering) </li>
<li>The device width is 420px</li>
<li>You can see that the 'large' image size has been selected in the Wordpress editor by the 'size-large' class on the image, so the full size should not be downloaded at all </li>
<li>I have tested this on another wp site and same issue... selecting image size has no effect on chrome android</li>
<li>You can see it yourself in action here: blog.londolozi.com/2017/08/04/the-week-in-pictures-295/</li>
</ul>
<p>So I don't know how to explain this behaviour.</p>
<p><strong>Am I correct in asserting that if I explicitly set a size when inserting an image into a post, that the image downloaded by the browser should not be larger than that size, no matter what? Or else setting a size is redundant.</strong> </p>

" );
return $result[0][1] . "<br />";
}
```
Put this code inside your theme's `functions.php` file, and then head over to `New > Page` and create a page. Afterward, you can use this shortcode inside your page:
```
[my-shortcode]
```
This will execute and output your code. Also note that you can not `echo` content in a shortcode, you must `return` it.
Another approach is to simply wrap it as a function without creating a shortcode, and then call that function inside your templates.
```
function create_my_shortcode(){
// Your code here
}
```
Now, make a copy of your theme's `page.php`, rename it to `page-whatever.php` and modify it the way you like. After you finished editing, use `create_my_shortcode()` anywhere you want. In this method you can `echo` the content too.
Afterward, you can use this template while creating a new page in the back-end.
UPDATE
------
As stated in your comments, the results might be an array. To print the array, you can use a foreach like this:
```
$data = '';
foreach( $result as $single_result ){
$data .= $single_result;
}
return $data. $row['VillageLeadersName'] . "<br />";

| **\*UPDATE - This wasn't showing because of a cache issue. The comment referencing changing the jQuery to :first-child instead of :first was indeed the only issue that needed to be addressed. \***
I am creating a WordPress theme and the image slider fails to do three things:
1) When clicking an indicator it does not do anything.
2) The image slider does not slide automatically.
3) The first indicator is never on.
I know the content is present because if I add a Post with the Category slider the image will display along with the title and a new carousel indicator. I also checked the DOM and all of the data-slides are there but nothing is moving. Any help is appreciated.
**HTML/PHP**
```
<?php
$number = 0;
query_posts('category_name=slider');
if(have_posts()):
?>
<div id="carousel-example-generic" class="carousel slide" data-ride="carousel">
<ol class="carousel-indicators">
<?php while(have_posts()): the_post(); ?>
<li data-target="#carousel-example-generic" data-slide-to="<?php echo $number++; ?>"></li>
<?php endwhile; ?>
</ol>
<!-- Carousel items -->
<div class="carousel-inner">
<?php while(have_posts()): the_post(); ?>
<div class="item">
<?php $image = wp_get_attachment_image_src( get_post_thumbnail_id ( $post->ID ), 'single-post-thumbnail' ); ?><a href=#"><img class="img-responsive" src="<?php echo $image[0]; ?>" />
<div class="carousel-caption">
<?php the_title();?>
</div>
</div></a>
<?php endwhile; ?>
</div>
</div>
<?php endif; wp_reset_query(); ?>
```
**jQuery**
```
//Carousel Indicator
$(".carousel-indicators li:first-child").addClass("active");
$(".carousel-inner .item:first-child").addClass("active");
``` | Add below code in `wp-config.php` file.
```
define('WP_MEMORY_LIMIT', '256M');
```

```
date_i18n( get_option( 'date_format' ), strtotime( '11/15-1976' ) );

| I am trying to do a simple basic shortcode and it fails. I have boiled it down to the most simple test and it still fails.
Here is the code:
```
/** My test shortcode */
function bp_basic_shortcode() {
return "This is a shortcode doing this!";
}
add_shortcode( 'basic_shortcode', 'bp_basic_shortcode');
```
In trying to figure out what is the reason I have:
I have put this in the functions.php file of the stock template twentytwelve
I have deactivated all plugins
I have added the shortcode [basic-shortcode] in both a post and a page as a test with the same result.
I used the "text" tab of the editor to add the shortcode
I see just the text of [basic-shortcode] but it is not being processed.
I even installed a plugin to show all active shortcodes and it is indeed in the list.
I have tried it both on an instance of my MAMP server and one on my VPS
This should be really simple. What am I missing?? | You registered the shortcode `basic_shortcode`, but you tested the wrong `[basic-shortcode]`. These are two different things. |

<pre><code>$posts_to_exclude = [ 67, 68, 69 ];
$query = new WP_Query( [

<p>My question is how do you show the correct number of posts per page when filtering out the posts via php? The example above adds the count of the excluded posts to the posts_per_page variable. However this would result in there being between 5 – 8 posts per page depending on how many posts are excluded for a particular page. Is there a workable solution for making the number of posts per page consistent or is this optimisation only really meant for posts that aren't going to be paginated?</p>

The thing is that there are a lot of doctors (more 5k pages), so when I try to set `'posts_per_page' => -1` it's not working.
```
$args = array(
'posts_per_page' => -1,
'post_type' => 'doctors',
'orderby' => "ID",
'nopaging' => true
);
$listDoctors = new WP_Query($args);
```
Have you any idea how to do this working? | Here is one approach, by using an `iframe` for the AJAX request it can be much easier to learn and debug your AJAX code... try this:
```
function videos_info() {
global $wpdb;
// add LIMIT 3 here
$videos = $wpdb->get_results( "SELECT * FROM wp_ifvideos ORDER BY id DESC LIMIT 3" , ARRAY_N);
foreach ( $videos as $video ) {
echo do_shortcode("[video width='256' height='144' poster='$video[3]' mp4='$video[2]'][/video]");
echo $video[1]. '<br>';
}
$ajaxurl = admin_url('admin-ajax.php');

echo "<script>function loadmorevideos(offset) {

echo "<div id='morevideos-3'><a href='javascript:void(0);' onclick='loadmorevideos(\"3\");'>Load More Videos</a></div>";
}
// For Logged in Users
add_action('wp_ajax_video_ajax', 'video_ajax');
// For Logged Out Users
add_action('wp_ajax_video_ajax', 'video_ajax');
function video_ajax() {
global $wpdb;
$videos = $wpdb->get_results( "SELECT * FROM wp_ifvideos ORDER BY id DESC" , ARRAY_N);
$offset = $_GET['offset']; $html = '';

// limit to 3 videos using offset

$html .= do_shortcode("[video width='256' height='144' poster='$video[3]' mp4='$video[2]'][/video]");

The story is different. The browser will look inside the `path` folder, based on where the *stylesheet* is located, not the current URL. So, if the stylesheet is located at:
```
www.example.com/wp-content/themes/twentyseven/
```
Then browser will look for:
```
www.example.com/wp-content/themes/twentyseven/path/image.jpg
```
Which doesn't exist. So it's important to build your CSS paths relative to the stylesheet's path.

PHP offers a function that can list files and directories. By using [`glob`](http://php.net/manual/en/function.glob.php) you can list every `.js` file in your directory, and then enqueue them by a loop.
```
function enqueue_my_scripts(){
foreach( glob( get_template_directory(). '/path/*.js' ) as $file ) {
// $file contains the name and extension of the file
wp_enqueue_script( $file, get_template_directory_uri().'/path/'.$file);
}
}
add_action('wp_enqueue_scripts', 'enqueue_my_scripts');
```
A side not is that `glob` uses relative path, but `wp_enqueue_script` uses URLs. That is why I used different functions to get the folder's path and URI. |

The Problems
------------
### Race Conditions Make the Data Super Unreliable
Updating post meta, options, terms, etc is not an atomic operation. You need to fetch the view count, add 1 to it, then send it back to the database.
During that process, another page load is occuring which does the same thing, leading to the following situation:
* user 1: get\_post\_meta 5!
* user 2: get\_post\_meta 5!
* user 1: adds 1, 6!
* user 2: adds 1, 6!
* user 1: saves update\_post\_meta, 6 views!
* user 2: saves update\_post\_meta, 6 views!
Now your counter says 6, when it should say 7.
### Huge Performance Costs
Database writes are a lot more expensive than reads, and this system involves a database write on every page load. This will not scale, and will have significant performance and speed problems.
So How Do I Track Page Views?
-----------------------------
External services and software. These kinds of systems need to be built in a particular way so that they give reliable information without being super slow. It isn't an easy task.
So instead, use a 3rd party service, and pull that information in at regular intervals. You could make a fresh request every time you view a page to get 100% accurate data, but that would be even slower, you wouldn't be able to cache the pages, and load times could be higher than 10 seconds, which is awful for SEO and UX.
On my own site, I pull Google Analytics data in every hour for the top 10 viewed posts, the 10 most recent, and 10 posts that have not been checked recently ( I save a timestamp for when they were last checked, and use the 10 oldest timestamps ) |
276,960 | <p>I think I've been looking at too much code and have confused myself while trying to get a better understanding of forms in WordPress with AJAX. I set out this week to learn how to create a form for a page and submit it through AJAX. </p>
<p>The page is a template and the action I've looked into two solutions of the handling. One through a redirect to a PHP, such as:</p>
<pre><code><form action="<?php echo get_template_directory_uri() . "/validation.php"; ?>" id="contactForm">
</form>
</code></pre>
<p>after reading several posts on the topic that a separate validation of the form should be made. Is this correct and why? Then the other issue is if I do want to process the form on the template-page the form action should look like:</p>
<pre><code><form action="#" id="contactForm">
</form>
</code></pre>
<p>but outside of WordPress I've seen:</p>
<pre><code><form action="" id="contactForm">
</form>
</code></pre>
<p>why is this? On the AJAX portion I've seen a difference of:</p>
<pre><code>jQuery.ajax({
type :"post",
url: ajaxurl,
}
});
</code></pre>
<p>then a different URL of:</p>
<pre><code>jQuery.ajax({
type :"post",
dataType:"json",
url: MBAjax.admin_url,
}
});
</code></pre>
<p>and lastly:</p>
<pre><code>jQuery.ajax({
type :"post",
dataType:"json",
url: /wp-admin/admin-ajax.php?action=contactForm",
}
});
</code></pre>
<p>So what is the proper way to write the action in WordPress if:</p>
<ul>
<li>If the form is processed on the same page?</li>
<li>If a separate PHP file validates the form?</li>
</ul>
<p>Then what is the proper AJAX call in WordPress?</p>

| I think I've been looking at too much code and have confused myself while trying to get a better understanding of forms in WordPress with AJAX. I set out this week to learn how to create a form for a page and submit it through AJAX.
The page is a template and the action I've looked into two solutions of the handling. One through a redirect to a PHP, such as:
```
<form action="<?php echo get_template_directory_uri() . "/validation.php"; ?>" id="contactForm">
</form>
```
after reading several posts on the topic that a separate validation of the form should be made. Is this correct and why? Then the other issue is if I do want to process the form on the template-page the form action should look like:
```
<form action="#" id="contactForm">
</form>
```
but outside of WordPress I've seen:
```
<form action="" id="contactForm">
</form>
```
why is this? On the AJAX portion I've seen a difference of:
```
jQuery.ajax({
type :"post",
url: ajaxurl,
}
});
```
then a different URL of:
```
jQuery.ajax({
type :"post",
dataType:"json",
url: MBAjax.admin_url,
}
});
```
and lastly:
```
jQuery.ajax({
type :"post",
dataType:"json",
url: /wp-admin/admin-ajax.php?action=contactForm",
}
});
```
So what is the proper way to write the action in WordPress if:
* If the form is processed on the same page?
* If a separate PHP file validates the form?
Then what is the proper AJAX call in WordPress?

Edit:

After further reading decided to step into RESTful submissions. I referenced "[REST APIs for Absolute Beginners](https://speakerdeck.com/tarendai/rest-apis-for-absolute-beginners)" but I'm not getting the return I'm hoping for:
**HTML:**
```
<form id="contactForm" action="" method="POST">
<div class="form-group">
<label for="form_email"><span class="asterisk">*</span>Email address:</label>
<input type="email" class="form-control" id="form_email">
</div>
<div class="form-group">
<button id="form_submit" class="supportbutton" type="submit">Submit</button>
</div>
</form>
<div id="testForm"></div>
```
**jQuery:**
```
$(document).ready(function() {
$('#contactForm').submit(function(e) {
e.preventDefault();
jQuery.ajax({
url: '<?php echo home_url(); ?>/wp-json/darthvader/v1/contact',
type: 'post',
dataType: 'json',
data: $('#contactForm').serialize(),
success: function(data) {
$("#testForm").html(data);
},
error: function() {
alert("There was an issue");
},
});
});
});
```
**functions.php:**
```
add_action('rest_api_init', function() {
register_rest_route('darthvader/v1', '/contact/', array(
'methods' => 'POST',
'callback' => 'darth_contact_form'
));
});
function darth_contact_form(\WP_REST_Request $request) {
$email = $request['form_email'];
return "Your contact request had the title " . $email;
}
```
Why do I only get `Your contact request had the title` on the return and not the email too? | ```
<form action="<?php echo get_template_directory_uri() . "/validation.php"; ?>" id="contactForm">
```
So I'll outline the basic fundamentals, so you have a framework to move forwards with
Fixing Admin AJAX
-----------------
So I'll cover this very briefly as it's not the crux of my answer, but would be useful:
* Add a hidden input field named `action` rather than adding it to the URL
* `validation.php` and any other standalone files should burn with the fire of a thousand suns, do this validation in JS, and again in the form handler. Handling the form and validating it are the same step, else someone could skip validation and go straight to handling
Finally, use a standard form handler for when JS isn't used/possible, check for the existence of something in the form that would only happen if it's been submitted, and submit the form to the same page, by having an empty action attribute e.g.:
```
if ( !empty( $_POST['form_page'] ) ) {
$valid = false;
// do validation
//
if ( true === $valid ) {
// yay do whatever submitting the form is meant to do
// if it's a multipage form, handle that here
} else {
get_template_part( 'form' ); // show the form again, but with warnings for validation
}
} else {
get_template_part( 'form' );
}
```
RESTful Form Submissions
------------------------
Change your form submission jQuery to use a REST endpoint, lets call this `darthvader/v1/contact`, I used some code from a [stackoverflow answer here](https://stackoverflow.com/a/1200312/57482):
```
jQuery('input#submitButton').click( function() {
jQuery.ajax({
url: '/wp-json/darthvader/v1/contact',
type: 'post',
dataType: 'json',
data: jQuery('form#contactForm').serialize(),
success: function(data) {
//... do something with the data...
}
});
});
```
That's pretty much every form submission via REST API you'll ever need, but you still need that endpoint to exist, '/wp-json/darthvader/v1/form' needs creating, so lets tell WP we want an endpoint, that accepts POST's:
```
add_action( 'rest_api_init', function () {
register_rest_route( 'darthvader/v1', '/contact/', array(
'methods' => 'POST',
'callback' => 'darth_contact_form'
) );
} );
```
Then define what will happen when it's called:
```
function darth_contact_form( \WP_REST_Request $request ) {
//
}
```
That's where we'll handle our form, e.g.:
```
function darth_contact_form( \WP_REST_Request $request ) {
$title = $request['title'];
$message = $request['message'];
// send an email or create a post, or whatever
// the contact form does when its submitted
return "Your contact request had the title ".$title;
}
```
The return value gets turned into JSON and sent back to the browser, so that you can handle it in the success function in javascript that you saw earlier in this answer. You can also return other responses, e.g.:
```
return \WP_REST_Response( "Bad request, X Y and Z are empty", 400);
```
and you can return a `WP_Error` object to indicate something going wrong or incorrect:
```
return new WP_Error( 'awesome_no_author', 'Invalid author', array( 'status' => 404 ) );
```
You can do your validation inside the endpoint, but you can also make the endpoint do the validation for you by specifying what fields to expect, and a function to validate them, but I leave that as an exercise ( or new question ) for you |

| I am trying to add custom add to cart link. I am getting product details from product slug. And trying to add, ADD to cart link by product id but no luck so far. Any help will be highly appreciated.

}
``` | ```
<form action="<?php echo get_template_directory_uri() . "/validation.php"; ?>" id="contactForm">
```
So I'll outline the basic fundamentals, so you have a framework to move forwards with
Fixing Admin AJAX
-----------------
So I'll cover this very briefly as it's not the crux of my answer, but would be useful:
* Add a hidden input field named `action` rather than adding it to the URL
* `validation.php` and any other standalone files should burn with the fire of a thousand suns, do this validation in JS, and again in the form handler. Handling the form and validating it are the same step, else someone could skip validation and go straight to handling
Finally, use a standard form handler for when JS isn't used/possible, check for the existence of something in the form that would only happen if it's been submitted, and submit the form to the same page, by having an empty action attribute e.g.:
```
if ( !empty( $_POST['form_page'] ) ) {
$valid = false;
// do validation
//
if ( true === $valid ) {
// yay do whatever submitting the form is meant to do
// if it's a multipage form, handle that here
} else {
get_template_part( 'form' ); // show the form again, but with warnings for validation
}
} else {
get_template_part( 'form' );
}
```
RESTful Form Submissions
------------------------
Change your form submission jQuery to use a REST endpoint, lets call this `darthvader/v1/contact`, I used some code from a [stackoverflow answer here](https://stackoverflow.com/a/1200312/57482):
```
jQuery('input#submitButton').click( function() {
jQuery.ajax({
url: '/wp-json/darthvader/v1/contact',
type: 'post',
dataType: 'json',
data: jQuery('form#contactForm').serialize(),
success: function(data) {
//... do something with the data...
}
});
});
```
That's pretty much every form submission via REST API you'll ever need, but you still need that endpoint to exist, '/wp-json/darthvader/v1/form' needs creating, so lets tell WP we want an endpoint, that accepts POST's:
```
add_action( 'rest_api_init', function () {
register_rest_route( 'darthvader/v1', '/contact/', array(
'methods' => 'POST',
'callback' => 'darth_contact_form'
) );
} );
```
Then define what will happen when it's called:
```
function darth_contact_form( \WP_REST_Request $request ) {
//
}
```
That's where we'll handle our form, e.g.:
```
function darth_contact_form( \WP_REST_Request $request ) {
$title = $request['title'];
$message = $request['message'];
// send an email or create a post, or whatever
// the contact form does when its submitted
return "Your contact request had the title ".$title;
}
```
The return value gets turned into JSON and sent back to the browser, so that you can handle it in the success function in javascript that you saw earlier in this answer. You can also return other responses, e.g.:
```
return \WP_REST_Response( "Bad request, X Y and Z are empty", 400);
```
and you can return a `WP_Error` object to indicate something going wrong or incorrect:
```
return new WP_Error( 'awesome_no_author', 'Invalid author', array( 'status' => 404 ) );
```
You can do your validation inside the endpoint, but you can also make the endpoint do the validation for you by specifying what fields to expect, and a function to validate them, but I leave that as an exercise ( or new question ) for you |

| please I need help with this code
```
add_action( 'the_title', 'adddd', 10, 2 );
function adddd( $title, $post_id )
{
if( has_category( 30, $post_id ) ) {
$title = 'Prefix ' . $title;

return $title;
}
```
Changing the post title of a specific category.
The code above is working fine displaying the prefix but am getting error when I tried adding a word or two after the post title.
Please any fix for this? Thanks. | You should use filter not action:
```
function adddd( $title, $post_id ) {
if( in_category( 30 ) ) {
$title = 'Prefix - ' . $title . ' - xxx';
}
return $title;
}
add_filter( 'the_title', 'adddd', 10, 2 );

So here is the full working code to loading a `wp_editor` instance with AJAX on the front-end, **including** the settings provided to `wp_editor`.
I think there might be an even better solution, as right now, I'm having to call `wp_print_footer_scripts()`, which *might* add some unnessacary stuff, but doesn't (in my case).

wp_enqueue_script( 'param-example', 'https://domain.com/example?f=j&s=w&c=t', array(), null );

How can I prevent WordPress from escaping the URL in `wp_enqueue_script`?
The other examples that seem close to this question haven't worked. | So, after doing some more digging, I answered my own question by "connecting the dots", so to speak. There's a lot of bits and pieces of info on this topic on StackOverflow and StackExchange, but none of them really answered my question.
So here is the full working code to loading a `wp_editor` instance with AJAX on the front-end, **including** the settings provided to `wp_editor`.

I can successfully pass information to the <code>WP_REST_Response</code> and I've added a check in <code>WP_REST_Response</code> and want it to return the error message back to the AJAX error function but I'm having issues.</p>
<p>For example on my local box the IP is <code>::1</code> and if I create a function in PHP:</p>
<pre><code>function ipAddress() {
if (isset($_SERVER['REMOTE_ADDR'])) :
$ip_address = clean($_SERVER['REMOTE_ADDR']);
else :
$ip_address = "undefined";
endif;
return $ip_address;
}

<li><a href="https://stackoverflow.com/questions/682260/returning-json-from-php-to-javascript">Returning JSON from PHP to JavaScript?</a></li>
</ul>
<p>so I added to my <code>WP_REST_Response</code>:</p>
<pre><code>function vader(\WP_REST_Request $request) {
if (ipAddress() == "::1") :
return json_encode(array(
'error' => 'you are localhost'

endif;
}
</code></pre>
<p>and in my vader.js if I use:</p>
<pre><code>error: function(data) {
throw data.error;
},
</code></pre>
<p>but I have no errors in the console and it shows <code>{"error":"you are localhost"}</code> but I'm just wanting the value to go to the error function. </p>
<p>Looking at <a href="http://api.jquery.com/jquery.ajax/" rel="nofollow noreferrer">jQuery.ajax() documentation</a> I found <code>statusCode</code> and I can get:</p>
<pre><code>if (ek_ip_address() == "::1") :

endif;
</code></pre>
<p>and:</p>
<pre><code>statusCode: {
404: function() {
$('#testForm').append("thrown 404s");
}
}
</code></pre>
<p>Is there a way to get <code>error</code> to show or am I misunderstanding AJAX <code>error</code>? What am I doing wrong and how can I get the JSON value return from <code>WP_REST_REQUEST</code> to go to the <code>error</code> function?</p>

* [Clean way to throw php exception through jquery/ajax and json](https://stackoverflow.com/questions/12693423/clean-way-to-throw-php-exception-through-jquery-ajax-and-json)
* [Returning JSON from PHP to JavaScript?](https://stackoverflow.com/questions/682260/returning-json-from-php-to-javascript)
so I added to my `WP_REST_Response`:
```
function vader(\WP_REST_Request $request) {
if (ipAddress() == "::1") :
return json_encode(array(
'error' => 'you are localhost'
));
endif;
}
```
and in my vader.js if I use:
```
error: function(data) {
throw data.error;
},
```
but I have no errors in the console and it shows `{"error":"you are localhost"}` but I'm just wanting the value to go to the error function.
Looking at [jQuery.ajax() documentation](http://api.jquery.com/jquery.ajax/) I found `statusCode` and I can get:
```
if (ek_ip_address() == "::1") :
return new WP_Error('foo', 'bar', array('status' => 404));
endif;
```
and:
```
statusCode: {
404: function() {
$('#testForm').append("thrown 404s");
}
}
```
Is there a way to get `error` to show or am I misunderstanding AJAX `error`? What am I doing wrong and how can I get the JSON value return from `WP_REST_REQUEST` to go to the `error` function? | An Ajax call can be sent to anywhere. It can be a server running a PHP, a virtual local route that is simulated using C#, or anything else. So, Ajax does not care what the response is, since it can't understand it.
When you are sending *any* data back from your server, as long as the status is 200 ( or anything but an error ), the Ajax script considers this a *successful* request. Afterward, it's up to you to handle the situation based on your response.
A Simple Example
----------------
I'm a novice at English language. I use the *"error"* word instead of *"success"* and return it as a response.
```
$data['status'] = 'error';
$data['message'] = 'Nice! Request has been done.';
return $data;
```
The server did successfully run the task, but has sent the wrong status. How would Ajax know that?
So, the error section of an Ajax call is for when there is a problem making the request, before it's finished, not after. After the response has been sent, Ajax did its job, it's considered a successful request.
Real Life Example
-----------------
1. Let's say you write a letter for a friend, and ask him do join you in
a business. You are the *"user"* here.
2. You give your letter to the post man for delivery. The post man is
the *"Ajax"* function here.
3. Your friend write a very big *"NO"* in his response (how rude),
seals the letter and passes it back to the post man. Your friend is the *"server"* here.
4. The post man delivers the letter back to you. The post man did his job, no matter what the response was. So he is considered a *"successful"* one at his job. (don't forget his tip)
5. It's up to you to choose whether to scream, shout or cry because of
your friend's strict *"NO"* (Error handling). It's not the post
man's problem. |

277,266 | <p>I know i'll get bombarded for this question but the truth is I researched and found nothing.</p>
<p>I'm not a WP expert or anything, i just found my ways to design WP themes. But there is something i never got straight. </p>
<p><strong><em>WHY IN HECK SHORT-CODES DON'T WORK FOR ME.</em></strong></p>
<p>When i mean shortcodes i mean the ones provided by a plugin, not created by myself what it makes it probably dumber. </p>
<p><strong>Example:</strong> </p>
<p>I write in a page or a post:</p>
<pre><code>[audio src="http://my_url.com/my_track.mp3"]
</code></pre>
<p>I see the audio controls in the WP editor, but in the browser i see the text, not the audio. </p>
<p><strong>2nd example:</strong> </p>
<p>I just tried to use a WPForms shortcode in order to display a contact form....
I see the text, not what the shortcode should be doing.</p>
<p>Up to this point my solution if I need to run a shortcode is creating a page/post template and do:</p>
<pre><code><?php echo do_shortcode('[My_shortcode]'); ?>
</code></pre>
<p>Thanks a lot and sorry for the dumbest question. </p>

| I know i'll get bombarded for this question but the truth is I researched and found nothing.
I'm not a WP expert or anything, i just found my ways to design WP themes. But there is something i never got straight.
***WHY IN HECK SHORT-CODES DON'T WORK FOR ME.***
When i mean shortcodes i mean the ones provided by a plugin, not created by myself what it makes it probably dumber.
**Example:**
I write in a page or a post:
```
[audio src="http://my_url.com/my_track.mp3"]
```
I see the audio controls in the WP editor, but in the browser i see the text, not the audio.
**2nd example:**
I just tried to use a WPForms shortcode in order to display a contact form....
I see the text, not what the shortcode should be doing.
Up to this point my solution if I need to run a shortcode is creating a page/post template and do:
```
<?php echo do_shortcode('[My_shortcode]'); ?>
```
Thanks a lot and sorry for the dumbest question. | It looks like theme issue. Switch to default WordPress theme and check it. I have tested it on WordPress Twenty Seventeen theme.
For testing:
1) Add below code in theme `functions.php`
```
// Sample shortcode [testme]
function testme_cb( $atts ) {
return 'Working? Maybe.';
}
add_shortcode( 'testme', 'testme_cb' );
// Enable shortcodes in text widgets
add_filter('widget_text','do_shortcode');
```
---
2) Goto `Appearance -> Widgets` and add shortcode `[testme]` in Text Widget.

277,343 | <p>I have a fresh WP install and for purposes of keeping things simple I currently just have a simple action as follows in my <code>functions.php</code>:</p>

Thank you | WordPress AJAX uses actions to connect your jQuery `action` with a traditional WordPress action. Take a look at the [example WordPress provides in their docs](https://codex.wordpress.org/AJAX_in_Plugins). There's 2 hooks:
```
add_action( "wp_ajax_{$jquery_action_string}", "callback_function_name" );
```
The above will only work for authenticated ( logged in ) users. For non-logged-in users we use `nopriv`:
```
add_action( "wp_ajax_nopriv_{$jquery_action_string}", "callback_function_name" );
```
So in our case we would use both:
```
function return_fruits() {
echo json_encode( ['fruits' => ['apples', 'pears']]);
exit();
}
add_action( 'wp_ajax_getFruits', 'return_fruits' );
add_action( 'wp_ajax_nopriv_getFruits', 'return_fruits' );
```
Note, I changed your call back function name to identify that the ajax action and the callback name do not need to be identical. Also note, you would want to **echo** this data instead of return it. |

<p>In my quest to solve this, I have resorted to downloading the complete site and database and searching for any references of <em>http//</em> and other variations, but this is not stored anywhere.</p>
<p>I have also tried various .htaccess adaptations but this did not solve the problem either. Here is my current version:</p>
<pre><code># BEGIN WordPress

When I'm logged into the main site's admin backend, the link to the network admin should be <https://top-node.com/wp-admin/network/>. However, this is rewritten to <https://http//top-node.com/wp-admin/network/> - there seems to be some (.htaccess) magic happening here.
In my quest to solve this, I have resorted to downloading the complete site and database and searching for any references of *http//* and other variations, but this is not stored anywhere.
I have also tried various .htaccess adaptations but this did not solve the problem either. Here is my current version:
```
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^(wp-(content|admin|includes).*) $1 [L]
RewriteRule ^(.*\.php)$ wp/$1 [L]
RewriteRule . index.php [L]
</IfModule>
# END WordPress
```
I'm at my wits end, so I'll appreciate any suggestions. | For me, it was removing `http://` from DOMAIN\_CURRENT\_SITE in my wp-config.php.
before
`define( 'DOMAIN_CURRENT_SITE', 'http://example.com' );`
after
`define( 'DOMAIN_CURRENT_SITE', 'example.com' );` |
277,515 | <p>By default, when you click on the author in a post, WP directs you to:</p>
<blockquote>
<p>example.com/author/sample-user/</p>
</blockquote>
<p>However, for BuddyPress users, it makes much more sense that it directs the user to the author's BuddyPress profile page: </p>

<p>example.com/members/sample-user/</p>

<p>Does anyone know how to do this? Thanks!</p>
<p>UPDATE
I'm trying with the following codes</p>
<pre><code>add_filter( 'author_link', 'change_author_link', 10, 1 );
function change_author_link($link) {
$link = 'http://asiaforum.club/members/' . $author_ID;
return $link;
}
</code></pre>
<p>But I can't seem to get wordpress to retrieve the author's user ID. Any idea on how to do that (or if this method will work)?</p>

How can i fix this problem? | You can fix this by changes `site_url` and `home_url` in your database.
If you have access to your database(phpmyadmin) go to `options` table and change `site_url` and `home_url` from HTTPS to HTTP.
You can also change it through `wp-config` file.
```
define('WP_HOME','http://www.example.com');
define('WP_SITEURL','http://www.example.com');
```
See: <https://codex.wordpress.org/Changing_The_Site_URL> for possible methods.
Hope this helps. |
