Time for action – Use advanced Ajax call

In this example, we will replace the simple Ajax call with a more advanced one that offers us more options and controls.

Open the wp-live-blogroll.js.php file and replace the load() function with the ajax() function:

$.ajax({
   type: "GET",
 
url: LiverollSettings.plugin_url + '/wp-live-blogroll-ajax.php',
   timeout: 3000, 
   data: 
   {
     link_url: this.href
   },
   success: function(msg) {
     jQuery('#lb_popup').html(msg);
     jQuery('#lb_popup').fadeIn(300);

   },
   error: function(msg) {
     jQuery('#lb_popup').html('Error: ' + msg.responseText);
   }
})

What just happened?

We have used an advanced jQuery function for handling the Ajax request, which obviously offers us more parameters.

The function allows us to specify the request type ('POST' or 'GET'), maximum script timeout and handlers for success and error results. This gives us full control over the events.

Tip

Full reference of the Ajax() function and available parameters are available at http://docs.jquery.com/Ajax/jQuery.Ajax

Ajax script security using nonces

WordPress provides a simple to use, but powerful security mechanism to protect your scripts from unauthorised execution by using the so called nonces.

Nonce means number used once and represents a unique number much like a password generated each time the script runs. The idea is to use nonces in order to verify whether our request was authentic.
