    <p>I'm following this <a href="http://byronyasgur.wordpress.com/2011/06/27/frontend-forward-facing-ajax-in-wordpress/" rel="nofollow">tutorial</a> to use front-end ajax to submit an email from a form and include information such as the current post title in the email. Please note I'm not an expert of php or ajax. Any advice or resources would be appreciated.</p> <p>I tried the following - but my hidden input field value below only returns a string, I assume this is because it gets included after the page loads.</p> <p>Jquery</p> <pre><code>function submit_me(){ jQuery.post(the_ajax_script.ajaxurl, jQuery("#theForm").serialize() , function(response_from_the_action_function){ jQuery("#response_area").html(response_from_the_action_function); } ); } </code></pre> <p>PHP</p> <pre><code>// enqueue and localise scripts function plugin_enqueue_scripts() { wp_enqueue_script( 'my-ajax-handle', plugin_dir_url( __FILE__ ) . 'ajax.js', array( 'jquery' ) ); wp_localize_script( 'my-ajax-handle', 'the_ajax_script', array( 'ajaxurl' =&gt; admin_url( 'admin-ajax.php' ) ) ); } add_action('wp_enqueue_scripts', 'plugin_enqueue_scripts'); // THE AJAX ADD ACTIONS add_action( 'wp_ajax_the_ajax_hook', 'the_action_function' ); add_action( 'wp_ajax_nopriv_the_ajax_hook', 'the_action_function' ); // need this to serve non logged in users // THE FUNCTION function the_action_function(){ /* this area is very simple but being serverside it affords the possibility of retreiving data from the server and passing it back to the javascript function */ $name = $_POST['name']; $title = $_POST['title']; echo"Title: " . $title;// this is passed back to the javascript function die();// wordpress may print out a spurious zero without this - can be particularly bad if using json } // ADD EG A FORM TO THE PAGE function hello_world_ajax_frontend(){ $the_form = ' &lt;form id="theForm"&gt; &lt;input id="name" name="name" value = "name" type="text" /&gt; &lt;input name="action" type="hidden" value="the_ajax_hook" /&gt;&amp;nbsp; &lt;!-- this puts the action the_ajax_hook into the serialized form --&gt; &lt;input id="submit_button" value = "Click This" type="button" onClick="submit_me();" /&gt; &lt;input name="title" type="hidden" value="&lt;?php the_title(); ?&gt;" /&gt; &lt;/form&gt; &lt;div id="response_area"&gt; This is where we\'ll get the response &lt;/div&gt;'; return $the_form; } add_shortcode("hw_ajax_frontend", "hello_world_ajax_frontend"); ?&gt; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
