    <p>In this jsfiddle</p> <p><a href="http://jsfiddle.net/littlesandra88/eGRRb/" rel="nofollow">http://jsfiddle.net/littlesandra88/eGRRb/</a></p> <p>have I submit buttons that are auto-generated. Each table row gets an unique ID number, and if needed each submit button can get the same unique number as well.</p> <p><strong>Question</strong></p> <p>The problem is that there are multiple submit buttons, so how do I know which was pressed?</p> <p><strong>HTML</strong></p> <pre><code>&lt;form action="" method="post"&gt; &lt;table class="alerts tablesorter" id="accTable" cellspacing="0"&gt; &lt;thead&gt; &lt;tr class="header"&gt; &lt;th class="activity-header"&gt; A &lt;/th&gt; &lt;th class="activity-header"&gt; Signed &lt;/th&gt; &lt;th class="activity-header"&gt; &lt;/th&gt; &lt;/tr&gt; &lt;/thead&gt; &lt;tbody&gt; &lt;tr class="row" id="7249"&gt; &lt;td class="activity-data"&gt;7249&lt;/td&gt; &lt;!-- tablesorter can't sort a column with check boxes out-of-the-box, so it needs something to sort on. That is why the span tag is here --&gt; &lt;!-- a jquery script is watching the state of the checkbox, so when clicked the value in the span is updated --&gt; &lt;td class="checkbox"&gt; &lt;span style="display:none;"&gt;0&lt;/span&gt; &lt;input name="signed" type="checkbox" &gt; &lt;/td&gt; &lt;td class="edit-column"&gt; &lt;input value="Save" type="submit" name="7249"&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr class="row" id="61484"&gt; &lt;td class="activity-data"&gt;61484&lt;/td&gt; &lt;td class="checkbox"&gt; &lt;span style="display:none;"&gt;1&lt;/span&gt; &lt;input name="signed" type="checkbox" checked &gt; &lt;/td&gt; &lt;td class="edit-column"&gt; &lt;input value="Save" type="submit" name="61484"&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/tbody&gt; &lt;/table&gt; &lt;/form&gt; </code></pre> <p><strong>JavaScript</strong></p> <pre><code>$(document).ready(function() { $("#accTable").tablesorter(); // :checkbox stops from executing the event on the save button. Same as input[type=checkbox] $('#accTable input:checkbox').click(function() { // insert 1 or 0 depending of checkbox state in the tag before the input tag. In this case &lt;span&gt; is before &lt;input&gt; // this is done so tablesorter have something to sort on, as it doesn't support checkbox sort out of the box. var order = this.checked ? '1' : '0'; $(this).prev().html(order); $(this).parents("table").trigger("update"); }); }); // sends the form content to server side, and stay on page $('form').live('submit', function() { alert('test'); // don't redirect return false; }); </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.
