I have a PHP page that is returning a JSON object like this: <pre><code> header('Content-Type:application/json'); echo <<<HERE_DOC [ {content: '{row2[contentFull]}', bigimages: '{$row3['catalogFileID']}'}] HERE_DOC; </code></pre> In my main page I have the following jQuery code: <pre><code>jQuery(function() { jQuery("select#rooms").change(function() { var options = ''; jQuery.getJSON("/admin/selection_about.php",{id:jQuery(this).val(), ajax:isAjax}, function(j) { for (var i = 0; i < j.length; i++) { options = j[i].topImage; document.getElementById('content1').value = j[i].bigimages; } }) }) }) </code></pre> So basically in my main page, I have a drop down. When an option is selected, it fires off an Ajax request back to the server. I get the data in JSON format and then a textarea, with ID 'content1', is updated based on that JSON object. The JSON object looks like this: <pre><code>[ { content: '&quot; this is some text&quot; blah blah, &quot; some more `text&quot; now some linebreaks; some more text and then another` linebreak.` `', bigimages: 'cfil1069' } ]` </code></pre> But there are errors that occur here and my textarea does not get updated. However, if I hardcode plain simple text to be returned in the JSON object, then my textarea is updated. Is there a condition for which data in the JSON object should not have HTML tags? Edit: As suggested, I changed my code to following in PHP code: <pre><code>$arr = array ('content'=>$rest1,'bigimages'=>$row3['catalogFileID']); echo json_encode($arr); </code></pre> However now in my jQuery code: length of j is 'undefined' ... <pre><code> jQuery.getJSON("/admin/selection_about.php",{id: jQuery(this).val(), ajax: isAjax}, function(j) { alert('here3: ' + j.length); // this shows undefined for (var i = 0; i < j.length; i++) { document.getElementById('content1').value = j[i].content; } }) </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.
