    The get_enclosed() function in WordPress is used to retrieve enclosures that are already attached to a post. An "enclosure" in this context typically refers to any type of multimedia content, such as audio, video, or images, that is embedded or attached to a post.

    Function Definition

    • Function Name: get_enclosed()
    • Purpose: To retrieve an array of enclosures (like audio, video, images, etc.) that are attached to a specific post.
    • Parameters:
      • $post_id (int, required): The ID of the post from which you want to retrieve the enclosures.
    • Return:
      • string[]: An array of strings, each string being a URL or a path to an enclosure attached to the specified post.

    Sample Usage

    Here's an example of how get_enclosed() might be used in a WordPress theme or plugin:

    <?php
    // Assume you have a post ID
    $post_id = 123; // Replace with the actual post ID
    
    // Retrieve the enclosures for this post
    $enclosures = get_enclosed($post_id);
    
    // Check if there are any enclosures
    if (!empty($enclosures)) {
        echo "<h3>Attached Media</h3>";
        echo "<ul>";
        foreach ($enclosures as $enclosure) {
            // Display each enclosure
            echo "<li>" . esc_html($enclosure) . "</li>";
        }
        echo "</ul>";
    } else {
        echo "No media attachments found.";
    }
    ?>
    

    In this example:

    1. We specify a post ID.
    2. We call get_enclosed() with this post ID to get an array of enclosures.
    3. We check if the array is not empty, indicating that there are enclosures.
    4. We loop through each enclosure and display it (in this case, as a list item).
    5. If there are no enclosures, we display a message stating that no media attachments were found.

    It's important to note that the function returns URLs or paths as strings, so you might need to handle them accordingly depending on what type of enclosure they represent (image, video, etc.) and how you want to display them.
