Filter link to existing content suggestion

Question

How can i filter the link given in "link to existing content".

Eg:

As in the above image. I just want WSP BANNER TO BE SHOWN.

where WSP BANNER & CALENDAR are custom POST types

Any help will be appreciable.

Answer 1

Currently there are no ready filters available for this purpose. A ticket has been posted for the request.Lets hope we get one soon.

Instead of hardcoding your custom post types its better to create a filter hook and use it

Till then you can create your own filter.

Open includes/class-wp-editor.php and make folowing changes at line no 712

$pt_names = apply_filters('custom_insert_link_suggestion_filter',array_keys( $pts ));

we just added a new filter instead of getting all the public post types

Then in your theme add following code to filter the internal link custom post type

function my_filter_function($allowed_post_types)
{


if( condition chek)
{
         return array('page','your custom post types');
}


}
add_filter('custom_insert_link_suggestion_filter','my_filter_function',10,1);

Answer 2

if it's very very urgent, you may be want to edit class-wp-editor line 711 to

$pts = get_post_types( array( 'name' => 'your_post_type','public' => true ), 'objects' );

, otherwise leave AS IS

Answer 3

Check the file class-wp-editor.php, line no. 742 onwards. The list doesn't have any filters applied to it. So I guess you can't change it!

More, in the same file, line no. 689, the function wp_link_query is called via an AJAX request for getting this list, it too doesn't have any filters to change the post types!

Hence, you have to live with it! ;)

Answer 4

I wrote a plugin for that. It is not in the plugins repository yet, you can download it here:

http://basics09.de/download/b09.link-to-existing-content.zip

Install it and then put this filter in your functions.php:

add_filter("link_to_existing_content_post_types", "my_link_to_existing_content_post_types");
function my_link_to_existing_content_post_types($post_types) {  
    $post_types = array("post", "page");
    return $post_types;
}

This plugin also has the functionality to replace internal links with shortcodes. If you don't want to use this, deactivate it like this:

add_filter("link_to_existing_content_use_shortcode", "disable_link_to_existing_content_shortcode");
function disable_link_to_existing_content_shortcode(){
    return false;
}

Hope this will be useful for you!
