Show Region Utility

I want the SpeciesSearch selection box to only appear if the user selects "One Species" in the HowManySpecies box.

I told the wizard to show it if the previous box equaled "One Species."

However it is not working.

Also, I would like to store the results of each SELECT box to SESSION variables before moving on to the next page. How do I do that?

See attached file.

You are confusing client and server side code. Since the form isn't submitted every time the select list changes, you can't use server side code to hide and show elements like you are attempting.

You would have to use javascript to hide and show the elements.

So it would look something like:

<tr>
<td>
<p>Are you looking for one species or all species?
<select id="HowManySpecies" name="HowManySpecies" onchange="showSpeciesSelect()">
<option value="">One Species</option>
<option value="1">All Species</option>
</select>
</p>
</td>
</tr>
<tr>
<td>
<p id="whichSpecies" >

Which species? <select name="SpeciesSearch" class="BlackHeadline3" >
<option value="value">Select a Species</option>
<?php
while(!$rsSpecies->atEnd()) { //dyn select
?>
<option value="<?php echo($rsSpecies->getColumnVal("CommonName")); ?>"><?php echo($rsSpecies->getColumnVal("CommonName")); ?></option>
<?php
$rsSpecies->moveNext();
} //dyn select
$rsSpecies->moveFirst();
?>
</select>

</p>
</td>
</tr>


and then on the bottom of the page you add:

<script>
function showSpeciesSelect() {
var howManySelect = document.getElementById('HowManySpecies');
if (howManySelect.selectedIndex == 1) {
document.getElementById('whichSpecies').style.display='block';
} else {
document.getElementById('whichSpecies').style.display='none';
}
}
showSpeciesSelect();
</script>

I forgot to paste in the div ID into the script in the example above. I've fixed that. Please update the script on the bottom of the page and see if that helps.

You can't save the values into the session "before" someone leaves the page. Session variables are stored on the server with php, so they have to be saved after a form post on the action page of the form.

You can add code to save the form element values into the session on the page specified as the form action page.

Nope, still doesn't work.

And the Select box still shows "Choose" no matter which option I select.

Can I get a url and FTP access to see the issue. It is hard to debug code without seeing it in context.

I had another typo in the script code. Please copy and paste it from above and try again.
