Description

The “fun_attachment_submitbox” filter is used to modify the image attach links.

A plugin (or theme) can modify the output with the code:

<?php add_filter( 'fun_attachment_submitbox', 'filter_function_name'); ?>

The hook is located in the file-un-attach/_inc/admin.php file.

Example

// Apply filter
function change_fun_attachment_submitbox( $links, $post ) {
return $links . ' <a href="#" id="custom-link-' . esc_attr( $postid ) . '">' . __( 'My link') . '</a>';
}
add_filter('fun_attachment_submitbox', 'change_fun_attachment_submitbox');

Note: $link is a HTML string, $post is an object or boolean value.
