Conditionals - Where are they parsed?

[mhuxtable]

I've tried asking this on vB.org but haven't had a response. Apologies if this is in the wrong place.

I've been trying to work this out for months: Where exactly are the conditionals in vBulletin templates changed to and parsed as PHP code to produce output for whether the conditional is true or not?

For example, say I had the conditional

<if condition="$foo">some text</if> 

in the calendar weekly template, (and $foo is set to 1 in a plugin elsewhere) where is the

<if condition="$foo"> 

parsed so that the "some text" appears on the page? I can't seem to just do it with eval(), there must be a function somewhere doing it.

Many thanks in advance

As far as I know the conditionals are parsed when the template is saved in the Style Manager.

Hi Colin, thanks for your quick reply.

I've had a look and it would appear that the saved templates in the database still have in tact

<if condition="$foo"> 

syntax stored with them.

I'll have another look myself anyway.

Many thanks

Still having trouble pinpointing this down. I'm probably not looking hard enough but if anyone knows I would be very grateful.

Nahh that wouldn't be possible, would ruin the whole point in the conditionals since they would't run at time of execution.

I haven't been able to find where this is either, and actually came here to ask this (I've asked before in another thread but no reply).

Thanks for your reply. It's probably something simple the way that they are parsed but I can't find it, and although I'm a "pretty good" PHP coder I'm not brilliant.

I've also tried asking over at vbulletin.org but no response there either. It seems it's a hidden secret! If anyone knows we would be grateful if it could be revealed!

Many thanks

Actually, I was under the impression that the templates were stored in a precompiled format, where conditionals were replaced with PHP, and this PHP was then evaluated during runtime.
If you look in the template table of the database you'll also see two fields, a template and a template_un.
The template field has PHP code in it, the template_un shows the code as we know it.

Hi Colin,

Thank you ever so much for your response. I've had a look now and everything makes sense.

If there was a "thanks" button or the reputation was switched on I'd click the button!

Thanks again. It is much appreciated.

Just thought I would mention that I have been studying the code for this for the past few days and have had trouble understanding parts of it, but I'm sure I will get back to normal over time and everything will make sense to me.

Many thanks
