uo_course_cert_img_path

Description

Usage

add_filter( 'uo_course_cert_img_path', 'your_function_name', 10, 2 );

Parameters

$post_id (mixed)

This parameter represents the desired path type for the certificate image, defaulting to 'path' but allowing filters to change it to 'url' to retrieve the image URL instead.

$thumbnail_id (mixed)

This parameter represents the ID of the post for which the certificate image path is being determined.

Return Value

The filtered value.

Examples

<?php
/**
 * Modify the course certificate image path to point to a custom directory.
 *
 * This filter allows developers to change the default location where the
 * certificate image is retrieved from. For example, you might want to
 * store custom certificate images in a theme-specific directory.
 *
 * @param mixed   $path       The default path or URL.
 * @param int     $post_id    The ID of the course post.
 * @param int     $thumbnail_id The ID of the featured image (thumbnail).
 * @return string The modified image path.
