How to use comment_reply_link filter in WordPress

comment_reply_link filter

Filters the comment reply link.

To use comment_reply_link filter, first you have to register it using add_filter. You can write this code into functions.php of your activated theme or in a custom WordPress Plugin.

We at WePlugins always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.

In the below live example, we have defined a function weplugins_modify_comment_reply_link_defaults which takes 4 parameters and we registered using add_filter. The first parameter comment_reply_link is name of the hook, The second parameter weplugins_modify_comment_reply_link_defaults is name of the function which need to be called, third parameter is the priority of calling the hook if same hook is used multiple times and the last parameter is the number of arguments (if any) to be passed in the registered function.

Sometime, you have to remove a registered hook so you can use remove_filter to remove comment_reply_link filter.

Parameters

Below are the 4 parameters required to use this hook.

• $link : (string) The HTML markup for the comment reply link.
• $args : (array) An array of arguments overriding the defaults.
• $comment : (WP_Comment) The object of the comment being replied.
• $post : (WP_Post) The WP_Post object.

Live Example

apply_filters( 'comment_reply_link', string $link, array $args, WP_Comment $comment, WP_Post $post )

Below is an example how you can use this hook.

Example 1: Modify the comment reply link

In this example, we modify the comment reply link using the weplugins_modify_comment_reply_link_defaults function and then register it with add_filter.

function weplugins_modify_comment_reply_link_defaults($link, $args, $comment, $post) { 
    // Update the $link variable according to your website requirements and return this variable.
    // You can modify the $link variable conditionally too if you want.
    return $link; 
}
// add the filter
add_filter( "comment_reply_link", "weplugins_modify_comment_reply_link_defaults", 10, 4 );

Example 2: Conditional modification of comment reply link

This example shows how you can conditionally modify the comment reply link based on certain criteria.

function weplugins_custom_comment_reply_link($link, $args, $comment, $post) { 
    if ($post->post_type == 'post') {
        $link .= ' - Custom Text';
    }
    return $link; 
}
// add the filter
add_filter( "comment_reply_link", "weplugins_custom_comment_reply_link", 10, 4 );

Example 3: Removing the comment reply link filter

If you need to remove the filter, you can use the remove_filter function as shown below.

remove_filter( "comment_reply_link", "weplugins_modify_comment_reply_link_defaults", 10, 4 );

Please make sure to provide the same callback function name, priority, and number of arguments while removing the hook callback.
