IF statement

[tazgalsinh]

and trying to do a IF statement, what it does is it check if the $totalcost has a value, if it does it goes to the next page and if it doesn;t then it will display message saying it is empty,

i have got this so far,

<?php
$number = (1);
if ($totalCost<$number)
{
echo "you have nothing in your cart";
}
if ($totalCost>$number)
{
include "output.php";
}
?>

thanks in advance to anyone who can help out

<?php
//check if $totalCost is NULL or 0
if (empty($totalCost))
{
	echo "you have nothing in your cart";
}
//now see if it is positive
elseif ($totalCost > 0)
{
	include "output.php";
}
//not positive, 0 or NULL? must be negative, absurd
else
{
	echo "error: negative value entered for total cost";
}
?>

do i have to pass the varible $totalcost from the previous page to check it, cause its always saying its empty at the moment

Of course.
You must remember that HTTP is a stateless protocol, hence you need to pass the value of the variable by the POST, GET etc methods.
