Function and usage of has_excerpt() in wordpress


Answers ( 1 )


    The has_excerpt() function in WordPress is used to determine if a specific post has a custom excerpt. This function is particularly useful for theme developers or when customizing the way content is displayed on a website.

    Function Signature:

    has_excerpt( int|WP_Post $post ): bool

    Function Details:

    • Purpose: To check whether a given post has a custom excerpt defined.

    • Description: In WordPress, an excerpt is a summary or a brief piece of content that represents a post. It's often used in themes to provide a snippet or a preview of the full post. The has_excerpt() function helps to identify if a custom excerpt is set for a post, as opposed to WordPress generating an automatic excerpt or having no excerpt at all.

    • Usage Scenario: This function is most useful in theme development. For instance, when designing a blog page, you might want to check if posts have custom excerpts to display them differently from auto-generated excerpts.


    • $post (int | WP_Post) (optional):
      • This parameter can be either the ID of a post (as an integer) or a WP_Post object.
      • If this parameter is not provided, the function will use the global $post object by default. This default behavior makes it easy to use within The Loop.

    Return Value:

    • bool:
      • The function returns true if the post has a custom excerpt.
      • It returns false if the post does not have a custom excerpt.

    Sample Usage:

    Here's an example of how you might use has_excerpt() in a theme file:

    if ( have_posts() ) {
        while ( have_posts() ) {
            if ( has_excerpt() ) {
                // This post has a custom excerpt
            } else {
                // This post does not have a custom excerpt
                // You can handle this case as needed, for example, display a default message or the content

    In this example, within The Loop, the function checks each post to see if it has a custom excerpt. If it does, the excerpt is displayed using the_excerpt(). If not, the else block allows for alternative content display or handling.
