    <p>I'm trying to use JSON, I'm getting the information from the server so I've written this PHP file: </p> <p> <pre><code> include("db_connect.php"); mysql_connect($host,$username,$password); @mysql_select_db($database) or die( "Unable to select database"); $result = mysql_query("SET NAMES utf8"); $query = "SELECT * FROM models WHERE models.product_id='".$product_selected."'"; $result = mysql_query($query); $json_object = "{ \"model\": ["; while($result_row = mysql_fetch_row($result)) { $json_object .= " {\"model_name\" : \"".$result_row[1]."(".$result_row[2].")"; $json_object .= "\"},"; } $json_object = substr($json_object,0,strlen($json_object)-1); $json_object .= " ]};"; echo json_encode($json_object); </code></pre> <p>?></p> <p>The output of the PHP file is in JSON format like this:</p> <pre><code>{ "model": [ {"model_name" : "xxxxx "}, {"model_name" : "xxxxx "}, {"model_name" : "link2(U)"}, {"model_name" : "xxxxx)"} ] }; </code></pre> <p>But i'm getting this response in Ajax like:</p> <pre><code>var my_JSON_object = {}; var xmlHttp = createXmlHttpRequestObject(); try { xmlHttp.open("GET", "ajaxproduct_new.php?product_id=" product_id,true); xmlHttp.onreadystatechange = function() { if (xmlHttp.readyState == 4 &amp;&amp; xmlHttp.status == 200){ my_JSON_object = JSON.parse( xmlHttp.responseText ); alert(my_JSON_object.model[0].model_name); } } xmlHttp.send(null); } catch (e){ alert("Can't connect to server:\" e.toString()); } </code></pre> <p>But when I'm doing alert of <code>my_JSON_object.model[0].model_name</code> it showing the error as <code>my_JSON_object.model</code> is undefined.</p> <p>Why is it coming like this? I have tried all the stuffs. Can any one please tell me?</p>

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.
