Variables turning blank.

[miz]

your problem is not in code or in templates
the problem is - you using
echo / print/print_r

this make page blank.....
instead of print put the var you want to print in template
and it will work.

No, my header.php is on a whole different domain (same box, just different users)

i tried using chdir() before and after including global.php but it still won't work, something about too many SQL connections after a short time.. (it's looping or something probably).

I just have no clue what to do about the whole $_GET-problem and I'm running out of ideas, I appreciate the help a lot though, Thanks.

I guess I'll end up print_r'ing $_GET through ~5000 lines of php code to find out where it gets lost =) Nothing like a nice relaxing Sunday afternoon..

It works on the top of global.php, but not at the bottom. I guess thats a start.

edit: MIZ, I didn't quite understand what you meant by your post, could you explain it a little more in detail?

if you try to echo and you use templates
that its wont show anything
not the echo and not the templates
if you included global this will happen to you

but if you will try to do something like

PHP Code:

echo "something here";
die; // you can user exit(); also 


then its will work,
you dont belive me ? try it.

also 1 more thing

$brand_new_var = $_GET['whatever'];

try to do it like that :

PHP Code:

$_GET['whatever'] = "bla";
$brand_new_var = $_GET['whatever']; 


then $brand_new_var will have a value.

Thanks Miz, but the problem isn't that it doesn't have a value, because it does at the top of global.php even when you do it my way as you quoted above. It's supposed to be a variable from the URL string, not a constant from within the script, and by the bottom of global.php the value is gone no matter how you set it..

And I don't want to just print it out in a template inside vb somewhere, I need it for db queries and to set cookies and stuff within my own header.php, and it's blank by the time it gets there.

you cant print anything when you using global.php
no metter what you will do
so right you placed it in top of global.php , after the file runned its shout its down
cuse this is the way global works
no metter what you will try to do
unless you will use the die(); function
which stop the file runing.

if you need to get all info use global
and instead of echo use template functions and put all vars in template
this is the best solution you can get

MIZ, I'm really having problems understanding how to "use the template functions to put the variables in a template"? how exactly would I do that to be able to pass the arrays $_GET, $_POST etc. to my header.php?

And the die(); thing in global makes the forum.. well.. die, and the point is for people to be able to browse the forum

PHP Code:

$myvar = "bla bla";

eval('print_output("' . fetch_template('mytemplate') . '");');

/* or if you want to get template in variable and then show it via formhome template for exsample use :
*/
eval('$newvar= "' . fetch_template('mytemplate') . '";'); 


then place $newvar in forum home template of where ever you want it to be showen.

offcurse in template 'mytemplate' place $myvar inside the template
