Im not 100% I have an answer, but I cant find comment anywhere so I will joust post here. <ol> <li>You cant access PHP variables from Javascript. PHP is running on the server, and Javascript is inside users browser.</li> <li>Javascript cant get $_GET and $_POST variables like PHP.</li> </ol> Now what you can do is this, with JavaScript you can get document.location string that holds your current URL. And you can brake that URL into parts. To do that use this function: <pre><code><script> var $_GET = {}; document.location.search.replace(/\??(?:([^=]+)=([^&]*)&?)/g, function () { function decode(s) { return decodeURIComponent(s.split("+").join(" ")); } $_GET[decode(arguments[1])] = decode(arguments[2]); }); alert($_GET['someVar']); // This will alert content of someVar </code></pre> Now you can use $_GET['vars'] to get your URL vars. And then you dont use PHP to echo variable content, you joust prepare your URL so it holds variables you want to insert into your form. So you do something like this: <pre><code><script type="text/javascript"> document.getElementById('text-386').value = $_GET['urlVar']; document.getElementByName('radio-30').checked = "checked"; document.getElementById('d-o-b-d').value = $_GET['urlVar']; document.getElementById('d-o-b-m').value = $_GET['urlVar']; document.getElementById('d-o-b-y').value = $_GET['urlVar']; </script> </code></pre> So as you can see, JavaScript takes variables from URL, using function $_GET you wrote and it dosent needs PHP. And you can use PHP to generate URLs you need, so they contain variables you can get using $_GET javascript function. Hope this answers your question.

1. COHey,thanks I get the principle but when I've added this to my code it doesn't seem to be materialising. I can alert the values out but this javascript doesn't seem to be materialising. Sorry if I'm missing something really obvious.

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.
