Hi

I have the following form fields generated by QuickForm:

<select onchange="this.form.url_manual.disabled=this.selectedIndex!=0;" name="url_automatic">
   <option value="none">Ekstern side</option>
   <option value="url1">Link to URL1</option>
   <option value="url2">Link to URL2</option>
   <option value="url3">Link to URL3</option>
</select>
<input value="Type URL" onchange="this.form.url_automatic.disabled=(this.value!='' &&
this.value!=this.defaultValue);" name="url_manual" type="text" />

These two fields are mutually exclusive meaning that either you choose an option from the drop-down
menu or you type in a value in the text field.

Now I want to add a crude validation to the text field helping the user to type in a correct URL and
I've reached the following:

$form->registerRule('url', 'regex',
'/(^(ldap|http|https|ftp):\/\/(([a-z0-9\-\.]+\.+[a-z]{2,6})|([0-9]{1,3}\.){4})(\]?)$)/');

But the problem is that an URL is ONLY required IF the first/default option from the drop-down menu
is active - if any other element is chosen, the text field is disabled and the rule shouldn't trigger!

How can I accomplish this behaviour using QuickForm?
