Function and usage of get_the_excerpt() in wordpress


Answers ( 1 )


    get_the_excerpt() is a function in WordPress used to retrieve the excerpt of a post. Here's a detailed explanation:


    • Name: get_the_excerpt()
    • Purpose: Retrieves the excerpt of a post.


    • $post (int|WP_Post, optional): This parameter can be either a post ID or a WP_Post object. If not specified, the function will use the global $post variable.
      • Type: Integer or WP_Post object.
      • Default: null.


    • Type: string
    • Description: Returns the excerpt of the specified post. If the post does not have an excerpt, it may return an auto-generated excerpt or an empty string, depending on the WordPress settings and the content of the post.

    Sample Usage:

    1. Basic Usage:

      echo get_the_excerpt();

      This will output the excerpt of the current post in the global $post variable.

    2. With a Post ID:

      $post_id = 123; // Replace 123 with the actual post ID
      echo get_the_excerpt($post_id);

      This will display the excerpt of the post with the ID 123.

    3. Using a WP_Post Object:

      $post_obj = get_post(123); // Get the post object for post ID 123
      echo get_the_excerpt($post_obj);

      Here, get_the_excerpt() is used with a WP_Post object obtained using get_post().


    • The function will use the excerpt explicitly set in the post editor if available. If not, it will generate an excerpt automatically by default, typically by taking the first few words of the content.
    • This function is useful for theme developers who want to display post excerpts on their templates, especially in post lists or summaries.
    • The behavior of the function can be modified by plugins or custom code, so it's important to consider the context in which it's being used.

    This function is part of WordPress's template system, allowing theme developers to easily display post excerpts without directly querying the database or manipulating the post content.
