How To Get the URL of the page you are on with PHP

  • I’ve built a little custom “send to a friend” pop-up where someone can enter their name and the email of a friend and send them a message about a particular post. I want to automatically include a link to the page they are on in the email, but I’m having trouble figuring out how to grab the url for the page they are on. Is there a WordPress function to do this? I tried using the basic PHP function echo $_SERVER[‘PHP_SELF’] which usually returns the page you are on, but it just seems to return index in this case. Any help would be greatly appreciate. Thanks much!

    Thanks, but my client had specific needs that this plugin couldn’t handle. I figured it out. <?php echo the_permalink() ?>

    the_permalink() will only work for single posts, not pages with multiple posts or archives. To do that, use the PHP $_SERVER global.

    When I came to this topic, I was looking for how to make my sites return to the current page after a user logged in, instead of the admin page. Here is the solution to that specific question:

    wp_loginout($_SERVER['REQUEST_URI']);

    This will create a log in or log out link (as appropriate) that will return the user to the current page.

    There’s more discussion on the topic in this bug:

    Yes it will work for lists of posts, providing they use a regular loop..

    the_permalink() is a loop function, it’s made for use “in the loop”.

    If you have a non-standard loop, you can just as easily use…

    echo get_permalink($ID); where $ID is a variable where you’re storing the ID for the “current” page/post in your custom loop or you can again use this with a single entry, just as long as you pass the ID into the fucntion.

    For what’s described above, get_permalink would be better suited.

    For what it’s worth, using the request uri you’d need to add the HTTP address on to..

    echo "http://" . $_SERVER['HTTP_HOST']  . $_SERVER['REQUEST_URI'];

    The request URI does not store the http address, just the query string etc…
