    <p>I'm having a problem with my ajax call. I'm submitting some info via php to mySQL, the submission part works perfectly, it's adding the data to the database, but the ajax function isn't loading that php in the background, it's loading it in the window and showing the php file results.</p> <p>Here's the HTML code.</p> <pre><code>&lt;form action="upload.php" class="addItem" method="post"&gt; Firstname:&lt;br&gt;&lt;input type="text" class="firstname" name="firstname" /&gt;&lt;br&gt; Lastname:&lt;br&gt;&lt;input type="text" class="lastname" name="lastname" /&gt;&lt;br&gt; Age:&lt;br&gt;&lt;input type="text" class="age" name="age" /&gt;&lt;br&gt; Photo:&lt;br&gt;&lt;input type="file" name="image" accept="image/jpeg" /&gt;&lt;br&gt;&lt;br&gt; &lt;input type="submit" class="submitItem" value="Add Row" /&gt; &lt;/form&gt; &lt;a href="logout.php"&gt;Logout&lt;/a&gt; &lt;/div&gt; &lt;script&gt; $(document).ready(function(){ $(".submitItem").click(function(){ // Start AJAX send jQuery.ajax({ // Enter below the full path to your "send" php file url: "upload.php", type: "POST", data: data, cache: false, success: function (html) { // If form submission is successful if ( html == 1 ) { $('.successMessage').show(200); $('.successMessage').delay(2000).hide(); } // Double check if maths question is correct else { $('.errorMessage').show(200); $('.errorMessage').delay(2000).hide(); } } }); }); }); &lt;/script&gt; </code></pre> <p>Here's the PHP code</p> <pre><code>&lt;?php $name = $_POST['firstname']; $surname = $_POST['lastname']; $age = $_POST['age']; if(($name === "") || ($surname === "") || ($age === "")){ echo "please fill in all fields"; } else { $con = mysql_connect("localhost","user","password"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("my_db", $con); $sql="INSERT INTO Persons (FirstName, LastName, Age) VALUES ('$_POST[firstname]','$_POST[lastname]','$_POST[age]')"; if (!mysql_query($sql,$con)) { die('Error: ' . mysql_error()); } if ($sql) { echo "1"; } else{echo "error";} } mysql_close($con); ?&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.
