Answers ( 1 )


    The get_page_template_slug() function in WordPress is a useful tool for developers working with themes and templates. It allows you to retrieve the specific template file associated with a given post. Here's a detailed explanation and sample usage:

    Function Signature

    get_page_template_slug( int|WP_Post $post = null ): string|false


    • Gets the specific template filename for a given post.
    • It's primarily used in theme development and plugins to determine which template file is assigned to a specific post.


    • $post (int|WP_Post, optional):
      • You can provide either the post ID or a WP_Post object.
      • If not provided, the function will use the global $post variable, which represents the current post in a WordPress loop.
      • Default value: null.

    Return Values

    • string|false: The function returns the page template filename as a string.
    • If the default page template is in use, it returns an empty string.
    • Returns false if the post does not exist or if there is an error.

    Sample Usage

    Scenario 1: Get Template for Current Post

    $template_file = get_page_template_slug();
    if ( $template_file ) {
        echo "The template file for this post is: " . $template_file;
    } else {
        echo "This post uses the default page template.";

    This code snippet will output the name of the template file used by the current post. If the post uses the default template, it will indicate so.

    Scenario 2: Get Template for a Specific Post ID

    $post_id = 123; // Assume 123 is a valid post ID
    $template_file = get_page_template_slug( $post_id );
    if ( $template_file ) {
        echo "The template file for post ID $post_id is: " . $template_file;
    } else {
        echo "The post uses the default page template or does not exist.";

    In this example, we're fetching the template file for a post with a specific ID.


    • This function is particularly useful in complex themes where different posts or pages might use different templates.
    • It helps in customizing content display or functionality based on the template assigned to a post.
    • Remember to check if the function returns false to handle cases where the post might not exist.

    This function is a part of WordPress's template system, and understanding its usage can greatly enhance theme customization and functionality.
