how to execute php code in the vb template

[larry_wic]

I've seen the link to the functions you can run, using the < if condition> tags, etc.

i saw somethign about a plugin (i was confused on that)

I don't see / understand how you do this?
I run this little code on all my pages, as i want to track how they got to my pages
[[ yes, i use other log analyzers, other track analytic software, but i have a specific reason why i need this too]]

so I do get how i could use the if condidtion tags to do this?
i can't call the script / include it -- as i loose the refer data.
i'm pretty sure i need to run it ASAP as the visitor lands on the page.


session_start();
if (empty($_SESSION['vREFERER'])) {
$vREFERER = $_SERVER['HTTP_REFERER'];
session_register('vREFERER'); }


so anyone know how, where i could run this php code in the vb template?

THANKS

As you've found out, raw PHP cannot be run inside templates. PHP must be run in plugins.

The Plugin Manager (http://www.vbulletin.com/docs/html/plugin_manager)

You can use PHP, but the template manager restricts what PHP you can use to these functions:


in_array
is_array
is_numeric
isset
empty
defined
array
can_moderate
can_moderate_calendar
exec_switch_bg
is_browser
is_member_of


http://www.vbulletin.com/docs/html/functions_in_conditionals



If you need something other than that, you'll have to do what Dismounted said and use a plugin.

That PHP is only allowed in conditionals, and no where else.

[larry_wic]

so i can't do this:

<if condition="session_start()">
if (empty($_SESSION['vREFERER'])) {
$vREFERER = $_SERVER['HTTP_REFERER'];
session_register('vREFERER'); }
</if>

you can tell, i don't get it :(

[Dismounted]

No, you can't do that. You must add a plugin to do what you want - I have already posted a link to the manual. Read it.

[TigerC10]

You can do this...


<if condition="empty($_SESSION['vREFERER'])">
Referrer: $_SERVER['HTTP_REFERER']
</if>


You can check if something is empty, but you can't assign new variables and you can't register anything...

[Dismounted]

That wouldn't work - the quotes would fail. Also, I don't know if you can access superglobals in templates directly (they may be cleared, or it might be at some other point, I don't remember).

You should take a look at the plugin section of the vBulletin manual to check out plugins and how they work. The architecture is a little strange at first but once you figure out the order, you can do a lot with it, including what you are trying to do I think.
