I want to harmonize my newly installed forum with the rest of my site. For this, I use xmlrpc to pull the site's html header in the hope of using same html code in the forum header.

I wrote the following plugin, using global_start as the hook. The code looks like this :

require_once('xmlrpclibrary.inc');
$m = new xmlrpcmsg('method.name');
$c = new xmlrpc_client("/xmlrpc.php", "mydomain.com", 80);
$r = $c->send($m);
if (!$r->faultCode()) {
$v = $r->val->me['string'];
}

$myhtmlheader = print $v;

*************
And then I put {vb:raw myhtmlheader} in the header template. Unfortunately, the result is output before anything else on the page (before the html <head> tag, before the DOCTYPE even, etc.).

I've also tried to replace the last line with:

ob_start();
print $v;
$myhtmlheader = ob_get_contents();
ob_end_clean;

but that doesn't seem to output anything in the template.

Any idea about what I'm doing wrong ?

Many thanks

Good question Max.

No it doesn't. I've tried it a numerous place, nesting it in different div tags, etc.

Have you tried different hooks?

I've tried a few, I don't remember which honestly. Right now I have debug mode turned on and I know I've tried global_start which I understand is called quite early, and also forumhome_complete and page_templates which are 2 of the last ones.

I'm stumped because I don't see anything in the code that would place this input information above the rest of the code in the header template. It should marry to where you put the call.

I have a feeling my issue may be related to the "print" in my code, perhaps that causes the problem as the global_start hook is called quite early.

I've also tried to replace the last line with:

ob_start();
print $v;
$myhtmlheader = ob_get_contents();
ob_end_clean;

This code actually has a typo in it, ob_end_clean; should be ob_end_clean();

Oddly enough, when I use this code with the typo (i.e. ob_end_clean;), the result is similar to simply using $myhtmlheader = print $v;, that is the output appears on the very top of the html document, before the DOCTYPE.

Using the proper ob_end_clean(); code doesn't return anything on the page.

Got it

require_once('xmlrpclibrary.inc');
$m = new xmlrpcmsg('method.name');
$c = new xmlrpc_client("/xmlrpc.php", "mydomain.com", 80);
$r = $c->send($m);
if (!$r->faultCode()) {
$v = $r->val->me['string'];
}

$myhtmlheader = $v;

vB_Template::preRegister(
'header', array('myhtmlheader' => $myhtmlheader)
);

then use {vb:raw myhtmlheader} in the template file.
