    <p>I have a webpage that returns search results in a table/form. I would like to have a select all checkbox, that would select all the checkboxes for the search results. My code for the display results is below:</p> <pre><code>&lt;form action="noJavaScript.php" name="theForm" method="post"&gt; &lt;table style="border: 1px solid black" RULES=ALL FRAME=VSIDES&gt; &lt;th&gt; &lt;/th&gt;&lt;th&gt;Order #&lt;/th&gt;&lt;th&gt;Inspector&lt;/th&gt;&lt;th&gt;Reference #&lt;/th&gt;&lt;th&gt;Client Name&lt;/th&gt;&lt;th&gt;Property Address&lt;/th&gt;&lt;th&gt;City&lt;/th&gt;&lt;th&gt;State&lt;/th&gt;&lt;th&gt;Zip&lt;/th&gt;&lt;th&gt;Inspection Date&lt;/th&gt; &lt;?php while ($row = mysql_fetch_assoc($result)) { echo '&lt;tr&gt;&lt;td&gt;'; echo '&lt;input type="checkbox" name="selected[]" value="'.$row['order_number'].'"/&gt;'; echo '&lt;/td&gt;'; foreach ($row as $key =&gt; $value) echo '&lt;td&gt;'.htmlspecialchars($value).'&lt;/td&gt;'; echo '&lt;/tr&gt;'; } ?&gt; &lt;/table&gt; &lt;input type="submit" name="submit" value="Edit/Modify Order" onClick="document.theForm.action='modify.php'"&gt; &lt;input type="submit" name="submit" value="Clone Order" onClick="document.theForm.action='clone.php'"&gt; &lt;input type="submit" name="submit" value="Delete Order" onClick="document.theForm.action='deleteorder.php'"&gt; &lt;input type="submit" name="submit" value="Archive Order" onClick="document.theForm.action='archive.php'"&gt; &lt;/form&gt; </code></pre> <p>I have tried using the following function:</p> <pre><code>&lt;script type="text/javascript" &lt;!-- function SetAllCheckBoxes(FormName, FieldName, CheckValue) { if(!document.forms[FormName]) return; var objCheckBoxes = document.forms[FormName].elements[FieldName]; if(!objCheckBoxes) return; var countCheckBoxes = objCheckBoxes.length; if(!countCheckBoxes) objCheckBoxes.checked = CheckValue; else // set the check value for all check boxes for(var i = 0; i &lt; countCheckBoxes; i++) objCheckBoxes[i].checked = CheckValue; } // --&gt; &lt;/script&gt; </code></pre> <p>And the button like this:</p> <pre><code> &lt;input type="button" onclick="SetAllCheckBoxes('theForm', 'myCheckbox', true);" value="Check All"&gt;; </code></pre> <p>But I can't get it to work.</p>

    1. COWhat does `myCheckbox` refer to? You don't name the checkboxes as such.

    2. COJavaScript works client-side; therefore the php is irrelevant. Can you post a representative example of the rendered html?

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.

SQuiL has stopped working due to an internal error.

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