Hmmm, really? Never realised that and am pretty interested in knowing why that is. This far I've been going out of my way to postpone sending a header as long as possible in my code.
I am pretty new to XOOPS 2.0 (even went so far as to mod PHPNuke to use Smarty, hehe) but pretty impressed as to it's workings. (Minus a few annoyances.)

As far as I understand it; postponing the invocation of the header file would only cause the page rendering commands to be grouped closer together in the code.

But since it is beyond the scope of this thread to discuss it: maybe you'd be willing to PM me the explanation or direct me to another thread or documentation where this has been done before?

(Speaking of documentation, wouldn't it be nice if phpDocumentor would also support documentation of $_GET and $_POST variables. Sometimes you have to plough through over 4 files of code to find the exact usage of such a parameter)

Antoine, here's the topic that explains that: Module-wide caching - Important development

Well it might help to answer Mithrandirs question about which theme you are using. If the theme doesn't do something like this setting the options won't help a bit:

Quote:
<{if $xoops_showrblock == 1}> <{/if}>


And also as stated before allways set the options BEFORE you include header.php. The header.php starts rendering the site so a good rule of thumb I use is to include it as late as possible. Possibly even right before you let Smarty render your template.

Sorry to not answer the thread question, but I have to get this myth beaten down below the floor:

header.php does NOT render ANYTHING - unless the page is cached, in which case you WANT it to render. header.php should be included as EARLY as possible, so as FEW database queries and code processing have been executed.

What you should do before including the header.php is:
a) Check page-specific permissions (module access perm is checked, but if you want e.g. only registered users or admin users to access it, this is the place to check for that)
b) Set $xoopsOption indexes such as template_main and show_rblocks
c) Nothing more

If you wait with including the header.php, you will have done all the processing and executed all the queries - but if the page is cached, it will just display that one, leaving the processing and query executions useless.

You should post a FAQ on this.

Do you know that you could enable a block when access to a particular modules or disable it in that modules?

That mean you could chose what block to appear in which modules or not....this a nice feature of xoops

It could be done in the block admin as mention earier...

NOTE: goto the block that appear in your right and edit it not to show in yours modules.
