    <p>I'm trying to achieve something basic, where you submit a form with a weight and it updates my database via ajax.</p> <p>I've been looking through some of the answered questions for guidance but I just can't figure out why the below code doesn't work.</p> <p>looking in chrome developer tools it look like it's not even submitting the form properly, so I don't think its the php script that's the issue (although it may have other issues once I fix the first problem).</p> <p>Any help with fixing this would be much appreciated.</p> <p>Here's the form and Ajax code</p> <pre><code>&lt;script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"&gt;&lt;/script&gt; &lt;script type="text/javascript"&gt; $("#weight_tracker_form").submit(function() { $.ajax({ type: "POST", url: "../weight_tracker_process.php", data: { weight: $("#weight").attr("value"), }, success: function(){ alert("success"); }, error: function(){ alert("error"); } }); return false; }); &lt;/script&gt; &lt;h2&gt;Weight Tracker&lt;/h2&gt; &lt;form id="weight_tracker_form" method="post"&gt; Date: &lt;input autofocus id="date" name="date" type="date"/&gt; Weight: &lt;input id="weight" name="weight" type="text"/&gt; Kg &lt;input type="submit" value="Submit Weight"&gt; &lt;/form&gt; </code></pre> <p>And here's the script weight_tracker_process.php</p> <pre><code>&lt;?php // configuration require("includes/config.php"); if ($_POST["weight"] == NULL) { apologize("Please enter an email"); } $weight = mysql_real_escape_string($_POST["weight"]); $date = mysql_real_escape_string($_POST["date"]); if (query("INSERT INTO weight (user_id, weight_measurement) VALUES (?, ?)", $_SESSION["id"], $weight); == false){ echo "Update Error"; } else { echo "Success"; } ?&gt; </code></pre> <p>Thanks!</p>

    1. COIn your jQuery data, you don't need a trailing comma on the last one, so it would be `data:{ weight: $("#weight").attr("value") }`

    3. COIt is not the script, it works right away if I reproduce it, pass a weight and return it back. Bt you should place the code in a document ready OR after your markup!!

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
