[resolved] global scope in plugins

trenc · 2009-07-25 16:01:26

Erm,

call me noob but I’m on the limit of my php/txp/plugin knowledge. Have I overseen something? Is there any mechanics inside TXP that prevend an global access on own variables inside of a plugin?

E.G.

$foo = 'bar';

function yab_print_foo()
{
	global $foo;
	return $foo;
}

All packed in a plugin … and it won’t work. :(

Try this instead:

global $foo;
$foo = 'bar';

function yab_print_foo()
{
	global $foo;
	return $foo;
}

You need to explicitly declare $foo as a global variable, because the plugin code is executed in an eval construct from within a function.

Won’t work too. :(

This gives me a syntax error.

Ah yes, it will work:

$GLOBALS['foo'] = 'bar';

function yab_print_foo()
{
        global $foo;
        return $foo;
}

I’ve edited my code example. Should work now. I mistakenly assumed that I could initialize a variable at the same time as declaring it global (similar to static variables).

Thanks Ruud,

your edited code works too.:)
