# External AJAX request

 * Hi,
 * I’m new to WP and I need some help with a situation. I’m developing an ‘help’
   site with documentation to an external platform.
 * The main goal is to have the Help Site but also load pieces of content in the
   platform, through AJAX requests. For example, in users section load the users
   related post/page.
 * I’ve been looking for examples and found:
    . DOING_AJAX . wp_ajax_($action) .
   wp_ajax_nopriv_($action) . wp_doing_ajax()
 * I’ve built a small plugin with this only to test:
 *     ```
       <?php
       var_dump(wp_doing_ajax());
       ?>
       ```
   
 * And added a button on footer to make an AJAX request. In both situations I get
   the same message:
    /wp-content/plugins/ajax-call/ajax-call.php:18:boolean false
 * AJAX request:
 *     ```
       $('#button').click(function(){
       		$.post(
       			'/', 
       			{
       					'action': 'add_foobar',
       					'data':   'foobarid'
       			}, 
       			function(response){
       				console.log(response);
       			}
       		);
       	})
       ```
   
 * Any idea on what am I doing wrong? Any suggestions or directions that I should
   take?
 * Would it be too wrong to use $_SERVER keys to detect an AJAX/external request?
 * Many thanks,
    mrocha

 * 1. you must determine ajax action something like this
 *     ```
       add_action( 'wp_ajax_'.'my_action', 'my_action' );
       add_action( 'wp_ajax_nopriv_'.'my_action', 'my_action' );
       ```
   
 * 2 determine function my_action
 *     ```
       function my_action(){
       echo "this is result";
       die;
       }
       ```
   
 * 3. then make ajax request pass like parameter action = my_action
 *     ```
       $.ajax({
        url: my_object.ajax_url,
        type: 'POST',
        data: {
          action: 'my_action',
          data: 'something',
        },
        success: function(msg){
          console.log(msg);
        },
       });
       ```
   
 * my_object.ajax_url this is you must pass variable to your javascript script or
   determine explicitly like [http://yourSiteName/wp-admin/admin-ajax.php](http://yourSiteName/wp-admin/admin-ajax.php).
 * instead this
 *     ```
       url: my_object.ajax_url,
       ```
   
 * add this
 *     ```
       url: 'http://yourSiteName/wp-admin/admin-ajax.php',
       ```
   
 * or add code that will add variable to you javascript file using this code
 *     ```
       add_action( 'wp_enqueue_scripts', 'includeJavaScriptPublic' );
       function includeJavaScriptPublic(){
        wp_enqueue_script( 'your-js-script', plugins_url('/path/to/your/script', dirname(__FILE__)), array('jquery'), '1.0.0', true);
        wp_localize_script( 
          'your-js-script', 
          'my_object', 
           array(
            'ajax_url'=>admin_url('admin-ajax.php'), 
           ) 
        );
       }
       ```
   
 * read better this documentations [link](https://codex.wordpress.org/AJAX_in_Plugins)
 * I think you need to spend a few days and then you will know how to do it. It’s
   not easy for newbie, I’d spent a few day to understand how it works, and not 
   so far don’t know how it works. always forget something…
