Permalink shortcode a href link

  • I’m trying to create a link to the current page. I’ve created a shortcode that prints the URL. This works fine. But as soon as I put the shortcode in a link the url is empty and the permalink is displayed as text on the page above where it should be?

    I just want to simply link to the current page permalink. This would be easy but WordPress doesn’t allow PHP in the page/post editor.

    My shortcode function:

    add_shortcode( 'my_permalink', 'my_permalink' );
// The Permalink Shortcode
function my_permalink() {
ob_start();
    the_permalink(2);
	$permalink = ob_get_clean();
print(urlencode($permalink));
}

    [my_permalink]
    Produces the permalink as text but

    <a href="[my_permalink]">link</a>
    creates an empty link and permalink as text.

    Why not have your shortcode just return the entire href statement?

    By the way, don’t use ob_* functions in your shortcodes. It can mess with system level caching.

    Thanks, that would be great but I’m not very good with PHP yet does this look OK with the ob_ removed:

    add_shortcode( 'my_permalink', 'my_permalink' );
// The Permalink Shortcode
function my_permalink() {
    the_permalink(2);
print(urlencode($permalink));
}

    The above code removes the url encoding.
    I will do some further research for including the whole href statement in one shortcode.

    no, because the_permalink echoes. You cannot “print” directly from a shortcode. Everything must be returned as a string.

    function my_permalink($atts, $content)j {
   return '<a href="'. get_the_permalink() .'">';
}

    With a bit of tweaking I got it to work. I just need the permalink URL to be encoded as it will be a variable on the end of a Facebook share URL.
