Getting URL out of submission code

[Mark.B]

In another thread there has been some discussion of creating a style chooser dropdown that actually updates the member's profile details.

We have achieved that part of it ok.

It works like the existing style chooser, from a drop down list that then refreshes the page.

That works fine, but I would *also* like to get a URL equivalent to the dropdown that achieves the same thing. This will be for use in the postbit where I have an entry showing people's style as a clickable link.

The submit code being used in the php file is this:

if ($_POST['do'] == 'updateoptions')
{
    if ($show['member']){

        $vbulletin->input->clean_array_gpc('p', array('newstyleset'    => TYPE_INT));

        $userdata =& datamanager_init('User', $vbulletin, ERRTYPE_STANDARD);
        $userdata->set_existing($vbulletin->userinfo);

        // style set
        if ($vbulletin->options['allowchangestyles'] AND $vbulletin->userinfo['realstyleid'] != $vbulletin->GPC['newstyleset'])
        {
            $userdata->set('styleid', $vbulletin->GPC['newstyleset']);
        }

        ($hook = vBulletinHook::fetch_hook('profile_updateoptions')) ? eval($hook) : false;
        $userdata->save();
    }
    else {
         exec_header_redirect("../index.php?");
    }
}

And the HTML in the template is this:

<input type="hidden" name="s" value="" />
     <input type="hidden" name="do" value="updateoptions" />
     <input type="hidden" name="securitytoken" value="$bbuserinfo[securitytoken]" />
     <select class="forumselector" name="newstyleset" id="sel_newstyleset"  onchange="this.form.submit()";>
   				<optgroup label="$vbphrase[quick_style_chooser]">
					$quickchooserbits
				</optgroup>    
     </select>

Could someone let me know if it's possible to submit this form via a clickable URL? Or failing that, a submit button would do.... And if so what the syntax is?
