[RESOLVED] syntax for is_integer

[ginginca]

I'm doing some error checking ... and am running into a question.

(Sorry - I'm learning).

I have typed the following:

[code]if (!is_integer($item_1_qty)) 

   {
	//qty is not a number
	$redirect_to = 'order_form.php?error=1';	
	header("Location: $redirect_to");
	exit();	
}[/code]

I don't understand why my is_integer is black when I am expecting it to be blue. I am getting an error, and think this line has something to do with it.

Not a clue what you mean there! But your code should work, unless you are getting a headers already sent error.

But you can use [man]is_int/man rather than [man]is_integer/man, as [man]is_integer/man is an alias if [man]is_int/man.

But you may want to use [man]is_numeric/man instead.

I figured out the problem. But thank you for reading my post and trying help out!
