If Profile Field Empty

[TheInsaneManiac]

I want to make a script not run if a profile field is empty, but can't seem to find a conditional for this. I don't want this script to run if my profile field is not filled in:

if($vbulletin->options['xbl_avatar_system_enable_product'] AND $vbulletin->options['xbl_avatar_system_display_navbar'])
{
$xblavatarfield = $vbulletin->options['xbl_avatar_system_userfield'];
eval('$xblavatarhead = "<td style=\"padding:1px\"><a href=\"member.php?".$vbulletin->session->vars[sessionurl]."u=".$vbulletin->userinfo[userid]."\"><img src=\"http://avatar.xboxlive.com/avatar/".$vbulletin->userinfo[$xblavatarfield]."/avatarpic-l.png\" border=\"0\" /></a></td>";');
}

You can access profile fields like this:

PHP Code:

$vbulletin->userinfo['fieldX']

So if($vbulletin->userinfo['field254']) would mean that if it is filled in it would run the script and if it wasn't it wouldn't run the script?

PHP Code:

if($vbulletin->userinfo['fieldx']){

// field x is filled

} else {

// field x is not filled

}

Let's apply some vBulletin coding standards there .

PHP Code:

if ($vbulletin->userinfo['fieldx'])
{
    // field x is filled
}
else
{
    // field x is not filled
}

} 


I don't guess there is to prevent someone from using the same profile field as someone else is there?

The field ID is the same for all users for a particular field. Each user is assigned their own row in the userfield table, which is fetched along with all the other user data.

So there is no way to detect if a field is the same as another?
