how to store additional fields to db during post

[radiofranky]

Hi

Someone helped me created a plugin that allows additional fields to be inputted during the post creation page. The code is as follows:

I have manually added three table_fields to my db because I want to store those three variable for later use.

I have "price", "saleprice", and "pct".


The problem I have now is I don't know how to store them? Which file should I edit and etc. Could someone show me how? Thanks

PHP Code:

vbulletin->input->clean_array_gpc('p', array( 
              'saleprice'         => TYPE_uinit, 
              'price'          => TYPE_uinit)); 
              $price = $vbulletin->GPC['price'];
              $saleprice = $vbulletin->GPC['saleprice'];
              vB_Template::preRegister('newthread', array('price' => $price, 'saleprice' => $saleprice)); 
$pct = intval((1-($vbulletin->GPC['saleprice']  / $vbulletin->GPC['price']))*100 );
          $vbulletin->GPC['subject'] .= " for $".$vbulletin->GPC['saleprice'] .", {$pct}% off (orig.$" . $vbulletin->GPC['price'] . ")";
