    The permalink_link() function in WordPress is a template tag used to print the permalink (permanent URL) of the current post within The Loop. The Loop is a WordPress mechanism for iterating over a set of posts, displaying content from each.

    Function: permalink_link()

    • Purpose: To print the permalink of the current post.
    • Usage Context: This function is used within The Loop in WordPress templates.

    Description:

    • The permalink_link() function outputs the URL of the current post in the loop.
    • Unlike the_permalink(), which is more commonly used, permalink_link() directly prints the URL to the screen.
    • It does not return a value; it only outputs the permalink.
    • This function is useful when you need to display the URL of a post as part of the post's content on a webpage.

    Sample Usage:

    if ( have_posts() ) : 
        while ( have_posts() ) : the_post();
            echo '<h2>';
            the_title();
            echo '</h2>';
    
            // Using permalink_link() to print the post's URL
            echo 'URL: ';
            permalink_link();
    
            the_content();
        endwhile;
    endif;
    

    In this example:

    1. The if ( have_posts() ) checks if there are posts to show.
    2. while ( have_posts() ) : the_post(); iterates over each post.
    3. the_title(); prints the title of the current post.
    4. permalink_link(); is used to print the URL of the current post.
    5. the_content(); displays the content of the post.

    Considerations:

    • It's essential to use permalink_link() within The Loop, as it relies on the global post object set up by The Loop.
    • If you need the permalink for use in PHP code (not for direct output), use get_permalink() instead.
    • Remember that this function prints the URL directly; it doesn't return it for further manipulation.

    See Also: the_permalink()

    • The the_permalink() function is similar but returns the permalink instead of printing it. It's more flexible for use in complex templates where the permalink needs to be passed to other functions or concatenated with other strings.
