    <p>I want to make an AJAX call to the server periodically, the server script(PHP) should make a new XML file. The XML file is then read by another javascript function and displayed on webpage. How do I accomplish this? Heres the Jquery code I have:</p> <pre><code>setInterval( function(){ $.Ajax({url: 'register.php'});}, 5000 ); </code></pre> <p>the PHP code that is being requested:</p> <pre><code>session_start(); $user = $_SESSION['username']; $uID = $_SESSION['UserID']; $host="127.0.0.1:3306"; $db_name='wf_db'; $tbl_name="tasks"; $connect = new mysqli("$host","root"," ","$db_name")or die('Can\'t connect to database!'); $sql = "SELECT * FROM $tbl_name WHERE UserID='$uID' and Task_Completed='0'"; $query_data = mysqli_query($connect,$sql)or die('Couldnt get data'); $row = mysqli_num_rows($query_data); chmod("result".$uID.".xml", 0755); if($row != 0){ $file = fopen("result".$uID.".xml",'w')or die("Cannot Open File"); $_xml = "&lt;?xml version=\"1.0\" encoding=\"UTF-8\" ?&gt;\r\n"; $_xml .="&lt;tasks&gt;\r\n"; while ($result = mysqli_fetch_array($query_data)) { if ($result["TaskID"]) { $_xml .="\t&lt;task&gt;\r\n"; $_xml .="\t\t&lt;AssignDate&gt;" . $result["Assign_Date"] . "&lt;/AssignDate&gt;\r\n"; $_xml .="\t\t&lt;TaskID&gt;" . $result["TaskID"] . "&lt;/TaskID&gt;\r\n"; $_xml .="\t\t&lt;TaskSubject&gt;" . $result["Task_Subject"] . "&lt;/TaskSubject&gt;\r\n"; $_xml .="\t\t&lt;Notes&gt;" . $result["Notes"] . "&lt;/Notes&gt;\r\n"; $_xml .="\t&lt;/task&gt;\r\n"; } else { $_xml .="\t&lt;task title=\"Nothing Returned\"&gt;\r\n"; $_xml .="\t\t&lt;AssignDate&gt;none&lt;/Assign_Date&gt;\r\n"; $_xml .="\t\t&lt;TaskID&gt;none&lt;/TaskID&gt;\r\n"; $_xml .="\t\t&lt;TaskSubject&gt;none&lt;/TaskSubject&gt;\r\n"; $_xml .="\t\t&lt;Notes&gt;none&lt;/Notes&gt;\r\n"; $_xml .="\t&lt;/task&gt;\r\n"; } } $_xml .="&lt;/tasks&gt;"; fwrite($file, $_xml); fclose($file); } else { echo 'Oops something went wrong!'; } </code></pre> <p>This is what I have so far, what am i missing? I am new to PHP and AJAX so there might be errors in the code.</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.
