<a href="<?php echo get_post_meta($post->ID,'mixtape_link',true); ?>" class="button small"><span>Download Now!</span></a>

i would like each link to count AND display how many times it has been clicked

Answer 1

Use the onclick event to call a is function. With that function call for a php file to increment a counter in a text file or in your database.

This is a very short plain example. JavaScript:

function increment() { 

$.ajax ({ url: "www.link.to/yourphpfile.php", 

data: { action : increment }, //optional 

}

PHP file:

if ($_POST["action"] == "increment") {

// increment your counter

}

This is not a complete example. You need to use a special solution for that in worpress. Take a look at this: http://codex.wordpress.org/AJAX_in_Plugins
