Nested Includes

[rkdiekhoff]

Hi everyone,

Is there a way to use a nested include in PHP without having the nested include automatically send the headers back to the browser?

For example, I have a PHP file called test.php that has a reference to an include file called createCookie.php:

<?php

include($_SERVER['DOCUMENT_ROOT'] . "/includes/createCookie.php");

$CartID = createCookie();

echo $CartID;

?>

Then within the include file createCookie.php, I reference a nested include file called openDatabase.php in the function createCookie():

<?php

function createCookie()
{
if(!isset($CartID))
{
virtual($_SERVER['DOCUMENT_ROOT'] . "/includes/openDatabase.php");

	$GetCurrentShoppingCartIDSQL = "SELECT ShoppingCartID FROM Increment";

	$ShoppingCartIDRow = mysql_query($GetCurrentShoppingCartIDSQL, $DbConnection);

	while($ShoppingCartIDResults = mysql_fetch_array($ShoppingCartIDRow))
	{
		$ShoppingCartID = $ShoppingCartIDResults["ShoppingCartID"];
	}

	$NewShoppingCartID = $ShoppingCartID + 1;

	$UpdateShoppingCartIDSQL = "UPDATE Increment SET ShoppingCartID = " . $NewShoppingCartID;
	if (!(@ mysql_query ($UpdateShoppingCartIDSQL, $DbConnection)))
		echo "Database Error";

	//Set the cookie
	setcookie("CartID", $NewShoppingCartID, time()+259200, "/", "", 0);
	mysql_close($DbConnection);

	$CartID = $NewShoppingCartID;
}
else
{
	$CartID = 0;
}

return($CartID);

}

?>

When I attempt to execute the test.php file however, I have a problem with the headers already being outputted. Is there a way the nested include can be used without error?

Thanks,
Ryan

hi,

Using [man]ob_start()[/man] at the top of the page, solves the headers already sent problem.

virtual i think is flushing the buffer to the browser try using require or include

or

you may have printed echoed or have whitespace before your call to setcookie
