register a variable through a hook

[emath]

hey,

im trying to do a realy simple thing - i just want to register a boolean variable that will be avaible in the "search_threadbit" template .

so ive added the following code with the location of "search_results_thread_process" hook :

PHP Code:

$templater->register_page_templates();
if ( strpos($_SERVER['HTTP_REFERER'],'pitronot') !== false ) {
    $diffPrev['bool']=true;
    $templater->register('diffPrev', $diffPreview);
}
else {
    $diffPrev['bool']=false;
    $templater->register('diffPrev', $diffPreview);
} 


though this gives me an error :

Fatal error: Call to a member function register_page_templates() on a non-object in .../packages/vbforum/search/result/thread.php(229) : eval()'d code on line 1

tried to use a class and an object instead of the array, this didnt work neither.

any suggestions?

I`M Sorry, this thread should have been under *vB4 Programming Discussions * please move the thread to this forum .

If I'm understanding what you want, then something like this should work:

PHP Code:

if ( strpos($_SERVER['HTTP_REFERER'],'pitronot') !== false ) {
    $diffPrev['bool']=true;
}
else {
    $diffPrev['bool']=false;
}  
vB_Template::preRegister('search_threadbit', array('diffPrev' => $diffPrev));

now i dont get an error though this if :

<vb:if condition="$diffPrev['bool']=true"> 555 </vb:if>

always gives true (even if in the last URL didnt have "pitronot" in it)

and this : {vb:raw $diffPrev.bool} gives nothing .

btw, why do i need to preRegister the variable if its a hook ?

* ofcourse im writing this codes in the search_threadbit template *

You need to use == instead of = (or don't compare it to true at all, since it's a boolean).

and this : {vb:raw $diffPrev.bool} gives nothing .

You don't need the $ there.

Basically you need to preregister unless you're rendering your own template, in which case you can use register() when you're doing the rendering.
