Xenforo Expressions

[Deleted member 6355]

Hi there,

I am a PHP noob trying to learn how to customize Xenforo a little bit. I am playing around with what I think are expressions:

$visitor['user_id'] > 0

How can I find a list of such expressions?

Perhaps you mean conditional statements?

Aha! Yes, seems like what I am looking for. It seems BD widget framework leverages this. It has an area called "Expressions" and leaves a blank space. Then it gives the hint:


Enter your expression here. Please use the correct PHP syntax and make sure you know 100% which variables are available in target position. For template position, all template parameters will be accessible but for hook position, only hook parameters will be accessible. Some common used expressions:

$visitor['user_id'] > 0 -- means: show the widget for logged in users only.

XenForo_Template_Helper_Core::callHelper('ismemberof', array($visitor,3)) -- means: show the widget for users of user group #3 only.


Does Xenforo have a list of commonly used expressions?

Conditional statements are for use in HTML templates.
The syntax is completely different from PHP.

There is no commonly used list as PHP code isn't generally used outside of PHP files, by developers.

Is $visitor['user_id'] > 0 a conditional statement?

That is PHP, as the add-on states:

Please use the correct PHP syntax
