Template input -> php -> db update, register variable's ? [SOLVED]

[Vaupell]

Allrighty then..

Getting a user confirmation user clicks a botton to confirm..

template where botton is clicked

<form action="ega.php?do=createNewUser" name="newuser" method="post";">
<input type="hidden" name="Uid" value=$bbuserinfo[userid] />
Confirm : <input type="submit" class="button" value="Create" />        
</form>

Then we head to the php code where the request should update a db field
from 0 to 1.

PHP Code:

if ($_REQUEST['do'] == 'createNewUser')
{
    $vbulletin->input->clean_array_gpc('p', array(
     'Uid'        => TYPE_UINT,
    ));

    $Uid =& $db->escape_string($vbulletin->GPC['Uid']);
    
$db->query_write("UPDATE " . TABLE_PREFIX . "user SET fieldEG1='1' WHERE userid='".$Uid."'"); 


strange thing as usual, no erros code runs fine.
But somehow i loose the Uid (userid) dureing the process,
and im sure its this VB4 variable register thing, but where would i register a variable that
comes from a template, and are put into the php ?

The article only shows how to take content from php and render them.
but this is userinput.

This won't work in vb4:

PHP Code:

<input type="hidden" name="Uid" value=$bbuserinfo[userid] /> 


You need to use the new syntax:

PHP Code:

<input type="hidden" name="Uid" value="{vb:raw bbuserinfo.userid}" />
