<p>Rather than using IDs all the time, use jQuery context and classes:</p> <pre><code><script type="text/javascript"> $(document).ready(function(){ $("form").submit(function(e){ e.stopPropagation(); var form = $(this); // We're going to use this instead of all those IDs $.ajax({ type:"POST", url:"ajax_form_test2-json.php", data: form.serialize(), dataType:"json", success:function(msg){ $(".response", form) .removeClass('error') .addClass(msg.status); .html(msg.message); $(".name", form).html(msg.name); $(".description", form).html(msg.description); }, error:function(){ $(".response", form) .removeClass('success') .addClass('error') .html("There was an error submitting the form. Please try again."); } }); return false; }); }); </script> </code></pre> <p>So, rather than this:</p> <pre><code><div id="static_description_<?php echo $row_rsStatic['id']; ?>" class="small_content"><?php echo $row_rsStatic['description']; ?></div> </code></pre> <p>You'll use a class instead:</p> <pre><code><div class="small_content description"><?php echo $row_rsStatic['description']; ?></div> </code></pre> <p>The approach:</p> <ul> <li>Use generic classes for your DIVs</li> <li>Use generic names for your INPUTs</li> <li>In your PHP <code>$_POST</code> handler, use the hidden ID field to know which record you're working with</li> <li>In your JSON response, use generic <code>status</code>, <code>message</code>, <code>name</code>, and <code>description</code> keys</li> </ul>

Guidance

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.
