PHP Code:


			
function displayHeader()        

{

        eval('$myheader = "' . fetch_template('myheader') . '";');

        echo $myheader;

}

displayHeader();

I have a custom template named 'myheader'. When I try to call it with the above function, I get a blank page. However, if I replace "fetch_template('myheader')" with "fetch_template('header')" vBulletin's standard header template is displayed.

How would I go about calling my custom template from this function?

That should help.

Interesting, but it doesn't seem to work.

Something else of note: if I take the code out of the function and call it inline, the custom template works fine. Maybe that helps...

Turns out that 'myheader' worked in the function. The problem was that 'myheader' contains references to vB's default header template (as '$header'), and that wasn't working within the function. To get around this, I have to manually call eval('$header = "' . fetch_template('header') . '";'); within the function.

This brings me to my new question: I have some plugin code in the global_start hook that works fine, unless I call it from within a function. How would I go about doing this?

If you want to access variable define outside a function you need to use the global keyword to enable it to work inside the function. For example:

PHP Code:


			
function displayHeader()         
{ 
        global $header;

        eval('$myheader = "' . fetch_template('myheader') . '";'); 
        echo $myheader; 
}

No need for the colon (does it even work that way?), it should be simply:

PHP Code:


			
global $header;

Oops my bad. Wasn't concentrating.

Thanks! A new challenge, though...

I'm now trying to fetch $myheader through a parse_templates plugin, so I no longer have to include that line in my function:

PHP Code:


			
// Code in vB's plugin system
eval('$myheader = "' . fetch_template('myheader') . '";');

// myheader template code in vB
$stylevar[htmldoctype]
<html id="moooo" dir="$stylevar[textdirection]" lang="$stylevar[languagecode]">
<head>
$headinclude
<title>$vboptions[bbtitle] - $pagetitle</title>
</head>
<body>
$header

// Function in my code, separate from vB
function displayHeader()         
{ 
        global $myheader, $header;
        echo $myheader; 
}

In my function, $myheader can't see the $header variable and $header isn't displayed. What am I missing?

Use var_dump and dump the variable to see if it exists.

It is not a VB3 engine, just a parsed copy!
