    <p>I have two forms here, the first is a select dropdown select, which when posted generates another form, creating an amount input boxes based on the number selected. This second form then puts the data from the input boxes into 2 array. All this works perfectly but I am trying to add extra functionality to the submit button on the second form. I created a function 'showcontet()' to show and hide the content in the div with id 'table'. This works perfectly when used on a button outside of the form. When used on the submit button inside the form you can see the content for about 1 second before it then disappears again.</p> <pre><code> &lt;head&gt; &lt;script type="text/javascript"&gt; showcontent = function(){ var content = document.getElementById('tabl'); content.style.display = 'inline'; } &lt;/script&gt; &lt;?php $userkey = array(); $userval = array(); $usernum = $_POST['usernum']; $total = 0; ?&gt; &lt;form action='MYPIE.PHP' method='POST'&gt; HOW MANY SECTIONS? &lt;select name="usernum" value="&lt;?php echo $usernum;?&gt;"&gt; &lt;option&gt;1&lt;/option&gt; &lt;option&gt;2&lt;/option&gt; &lt;option&gt;3&lt;/option&gt; &lt;option&gt;4&lt;/option&gt; &lt;option&gt;5&lt;/option&gt; &lt;option&gt;6&lt;/option&gt; &lt;option&gt;7&lt;/option&gt; &lt;option&gt;8&lt;/option&gt; &lt;option&gt;9&lt;/option&gt; &lt;/select&gt; &lt;input type="submit" name="submitnum" value="submit selection" /&gt; &lt;/form&gt; &lt;form action='MYPIE.PHP' method='POST'&gt; &lt;?php for ($i=1; $i&lt;$usernum+1; $i++){ echo '&lt;input type="hidden" value="' .$usernum.'" name="usernum" /&gt;'; echo "&lt;br&gt;insert key: &lt;input name='key".$i."' value='".$userkey[$i]."'&gt; insert value: &lt;input name='val".$i."' &gt;"; $userkey[$i] = $_POST["key".$i]; $userval[$i] = $_POST["val".$i]; } ?&gt; &lt;/br&gt; &lt;input type="submit" value="submit" name="submit keys" onclick="showcontent()" /&gt; &lt;/form&gt; &lt;/table&gt; &lt;div id="tabl" style="display:none;"&gt; content &lt;/div&gt; </code></pre> <p>Apologies for the bad indentation, I am pretty new to this &amp; thanks for any help</p>

    1. COSorry if the explanation didn't make sense. I am not trying to stop the form submitting, I am trying to get it to submit the data and run the showcontent() at the same time

    2. COIf you submit the form it will send a server request, so the page MYPIE.PHP will load. If you want to run showcontent() to change some div content and also submit the form, you should use ajax.

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).
