Warning: Cannot modify header information

I have no idea why these warnings are coming up. Here is my code in the Shipping.php

<?php

	//Variables from Order.php
	$Date = $_POST['date'];
	$Product = $_POST['prod'];
	$Quantity = $_POST['qty'];
	$Shipping = $_POST['ship'];
	$SubTotal = $_POST['sub'];
	$Tax = $_POST['tax'];
	$Total = $_POST['tot'];
		// Configures the current date.
		$Today = date("F j, Y");
		// Sets cookies from past Order.php form.
setcookie("date", "$Today", time()+3600);
		// Sets a cookie for the Product
setcookie("prod", "$Product", time()+3600);
		// Sets a cookie for the Quantity
setcookie("qty", "$Quantity", time()+3600);
		// Sets a cookie for the Shipping Price
setcookie("ship", "$Shipping", time()+3600);
		// Sets a cookie for the SubTotal Price
setcookie("sub", "$SubTotal", time()+3600);
		// Sets a cookie for the Tax Price
setcookie("tax", "$Tax", time()+3600);
		// Sets a cookie for the Total Price
setcookie("tot", "$Total", time()+3600);
?>

Whitespace above <?php ?

Whitespace in front of the < in <?php

Or in an included script..

There is output being sent to the browser, it's not lying. Check for whitespace.

It's most likely an error before the cookie values. As awpti said, check whitespace, and any included files, etc.. (i'm assuming that is only an excerpt from the full script).

session_start(), etc.. Has to be before anything is output.

Also if its UTF-8 encoded there's an opening set of bits that the browser 'outputs' i believe.

Yeah thats what I searched and found that it has to be white space..... The funny thing is, is theres not any white space. I can't figure it out. This is my entire code for Shipping.php theres not any PHP code in Order.php which is where its getting the values from.

function checkShipping() {
if (document.Shipping.fname.value.length == 0)
	{alert ("You must enter a first name"); return false;}

Those 41 or so lines of HTML/Javascript that you neglected to show in the first post (the line numbers in the error messages do not match what was shown) are all content that is sent to the browser.

You cannot output any content to the browser before you send a header. Setcookie requires a header. You must put the php logic first, then put the HTML/Javascript content.

Thanks, that was exactly it. I thought PHP had to be in the <body> guess not. Thanks!

jdm95lude · April 9, 2008

Well now theres another problem, when i put the php above the JavaScript it doesn't validate my fields. I mean I know I can do it in PHP but I like having alert boxes and the code is already in place. I really don't feel like re writing it again. Any ideas....
