I'm new to Php/Jquery Programming, and i past all this day trying figuring how to access to a JSON field from a Jquery AJAX call: I'm using codeingniter, and in my controller the related code is: <pre><code>if( $this->input->is_ajax_request()) { $view_data['test'] = 'ajax'; echo json_encode( $view_data ); } else { $view_data['test'] = 'not ajax'; $data = array( 'javascripts' => array( 'js/jquery.dataTables.js', 'js/zona/dataTable_zone.js', 'js/zona/gestisci_zone.js', 'js/jquery-ui-1.8.20.custom.min.js' , 'js/jquery.ui.error-panel.js', 'js/jquery.validate.min.js' , 'js/localization/messages_it.js' ), 'style_sheets' => array( 'css/south-street/jquery-ui-1.8.20.custom.css' => 'screen', 'css/jquery.dataTables.css' => 'screen' ), 'content' => $this->load->view( 'zona/gestisci_zone', $view_data, TRUE ) ); $this->load->view( $this->template, $data); } </code></pre> ` In the view the related code is <pre><code><div id="id_test"> <?php echo $test ?> </div> </code></pre> and in the javascript file the related AJAX code is `$.ajax( { type:"POST", url:this_url, dataType: 'json', data: post_data, success: function(data){ <pre><code> console.log(data); console.log($("id_test").empty()); $("#id_test").empty().append(data.test); }, error: function(data){ alert("error"); </code></pre> );` in this way the AJAX output is <code>Array{"test":"ajax"}</code> my expected behavior is that using <code>$("#id_test").empty().append(data.test);</code> the AJAX output will be just the word ajax, but it just return a blank div. I've tried to access in many modes but i didnt figured how to accomplish this. Maybe i'm missing something because of my lack of experience or i'm using a wrong approach. Any advice please? :) After a little of debug i've arrived to conclusion that is a plaintext / false JSON problem. it is returning just the text rapresentation of the array and not a json array. Now, how i can send the correct json array from controller? (i already forced mimetype to application/json with no effects)

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.
