Problem with ob_get_contents in a function??

[keitai]

Hi there,

I am stuck with this part of a class, well I am now trying it as a regular function

	function box_content($get_page) {
	ob_start();
	include('form.php');
	$html_content = ob_get_contents();
	ob_end_clean(); 
	return $html_content;
	}

The thing is my form.php has a hidden value and based on it's value it will display a message. is it true that ob_get_contents() parse the file and you just have the html-code.

When I just use

	ob_start();
	include('form.php');
	$html_content = ob_get_contents();
	ob_end_clean(); 

my hidden value is being checked and the messages are displayed.

Any tips

if the code in form.php is depending on certain variables being set to output certain things then you must bring those variables into the local variable scope of the function. read up on variable scope.

ah, that is the case.

Tx for your tip gonna read it.

Wow I got it (I think)

I just added

function box_content($get_page) {
[COLOR=Red]global $hiddenVar;[/COLOR]
	ob_start();
	include('form.php');
	$html_content = ob_get_contents();
	ob_end_clean(); 
	return $html_content;
	}

And now it seems to work 🙂

Am I using it correct???

[devinemke]

fine. but where are you using the $get_page argument inside the function? is that used inside of form.php?

oops wrong ctrl-c, ctrl-v

class Box {
......
......
function box_content($get_page) {
global $hiddenVar;
	ob_start();
	include($get_page);
	$html_content = ob_get_contents();
	ob_end_clean(); 
	return $html_content;
	}
......
.....

}

And use it like
$newbox = new Box;
$newbox->box_content('form.php');
