    <p>Hopefully this makes sense... but I am trying to write some initial ajax call to a test php page and i am getting an error within the console that reads:</p> <pre><code>Uncaught Error: Syntax error, unrecognized expression: {"projectId":"John","Project":"Some Project Name"} jquery-1.9.min.js:4 st.error jquery-1.9.min.js:4 ft jquery-1.9.min.js:4 wt jquery-1.9.min.js:4 st jquery-1.9.min.js:4 b.fn.extend.find jquery-1.9.min.js:4 b.fn.b.init jquery-1.9.min.js:3 b jquery-1.9.min.js:3 (anonymous function) download.js:27 c jquery-1.9.min.js:3 p.add jquery-1.9.min.js:3 (anonymous function) download.js:25 b.event.dispatch jquery-1.9.min.js:3 v.handle jquery-1.9.min.js:3 </code></pre> <p>This is my jquery ajax call:</p> <pre><code>$.get('test.php', {object_ID: 'kjiyu-drtfg-hjuyt-hiytr'}) .done(function(data) { console.log(data); $(data).each(function(index, element) { $('#fileList').append('&lt;option value="' + element.projectId + '"&gt;' + element.Project + '&lt;/option&gt;'); }); }); </code></pre> <p>This is my test.php page:</p> <pre><code>&lt;?php echo json_encode(array( array("projectId"=&gt;"John","Project"=&gt;"Some Project Name"), array("projectId"=&gt;"John2","Project"=&gt;"Some Project Name 2") )); ?&gt; </code></pre> <p>any advise would be greatly appreciated. In the end this will be hooked up to an actual page that looks up values from the database... I just want to get my first round going.</p> <p><strong>EDIT</strong></p> <p>I made the array change suggested but am now getting this error:</p> <pre><code>XMLHttpRequest cannot load file:///C:/Users/v-sthaff/Documents/School/Spring%202013/BIT%20286/Website/test.php?object_ID=kjiyu-drtfg-hjuyt-hiytr.

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.

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