help me to simplify my Quick Style Chooser mod

[JonZ]

vB Version: 3.7.3
Here's a summary of what I am trying to achieve:

I am trying to make the Quick Style Chooser (QSC) to actually record the theme into the users profile. What is the Quick Style Chooser? it the drop down list that appear at the bottom of vB pages, which allow you to change your theme design on the fly. You can actually see an example of it at http://www.vbulletin.com/forum



What this chooser don't do however is it doesn't record the theme into the users profile and just query the actual webpage to adjust the choosen theme based on cookies, which is fine for anonymous users.

What I did:

So I took the form in users Control Panel as a template, and take portions of code that would submit a selection the information based their values. On my HTML file, I put this html segment:

<form action="/board/myprofile.php" method="post" >
     <input type="hidden" name="s" value="index.php" /> <!-- same path location where this form is executed -->
     <input type="hidden" name="do" value="updateoptions" />
     <input type="hidden" name="securitytoken" value="<?=$vbulletin->userinfo['securitytoken']?>" />
     <select class="forumselector" name="newstyleset" id="sel_newstyleset"  onchange="this.form.submit()";>
   	    <?=$quickchooserbits?>                 
     </select>
</form>

notice that I replaced the original onchange="switch_id( this, 'style')" by "this.form.submit()". So when a selection is made, the script automatically do a submit action and bring the user to myprofile.php.

My problems:

I don't have a great understanding in PHP, but I can solve many issues by improvisations.
Here what I did is I torn appart the original profile.php where the information of a submition was treated in the user CP.

PHP Code:

<?php
// ####################### SET PHP ENVIRONMENT ###########################
error_reporting(E_ALL & ~E_NOTICE);

// #################### DEFINE IMPORTANT CONSTANTS #######################
define('THIS_SCRIPT', 'myprofile');
define('CSRF_PROTECTION', true);

// ######################### REQUIRE BACK-END ############################
require_once('./global.php');

// ############################### start update options ###############################
if ($_POST['do'] == 'updateoptions')
{
       $web = $_POST['s'];
    if ($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;
        $userdata->save();
    }    
    else {
        exec_header_redirect($web.'styleid');
    }    
}

// #############################################################################

exec_header_redirect('$web');

?>

The good news is, it working, almost. If I execute my html, choose an item from the dropdown list, it load myprofile.php, my theme change and the information is also changed in the user's profile (UCP). The bad news is, I haven't find a way to just change the theme based on cookies like the original QSC do for anonymous users, and I'm kinda stuck on this problem.

What the original QSC is doing to change the cookie's mode theme, is to get the value of a selected item, and paste it to the current address (ie: myweb.com/board/?styleid=45). You can try it on every board that support styles, take the web address and paste ?styleid=(styleid number here), you will browse temporarely on another theme. Where that query is being treated in the php files, I don't know.

The other problem, is the simplicity. I would like to not have an independent file (myprofile.php) to treat the transaction but in the html itself, just like the original QSC do. This way I could re-use the code on each new module without querying myprofile.php everytime, maybe in a form of a custom function. What I liked on the original QSC is I could just reuse the code in 3 lines, and that was it. This new one take 5-6 html lines, an independent file, and support codes for every page of my sites.

Also the problem with this code, is I have to specify a path with exec_header_redirect() function, when I just want to reload the same page I was before. Not very practical when I want to re-use this function on other pages.

This is where I am stuck. I really hope you will help me to resolve this.
Please do many suggestions you can.


Thanks advance.

PS/ The QSC on this very board is working exactly the way I want. It change on the fly, AND it is saved in the user's profile. You can verify it yourself. Choose a color, log out, then log back in, the style you have choosen still apply.
