Can't redirect : Warning: Cannot modify header information - headers already sent by (output started at /Applications

Hi there,

Re: Mikes Shirts Project When I try to pass a shirt without a valid id and without an id altogether, I am unable to redirect to shirts listing page.

This is the exact error message:

Warning: Cannot modify header information - headers already sent by (output started at /Applications/MAMP/htdocs/treehouse/shirts4mike/includes/products.php:2) in /Applications/MAMP/htdocs/treehouse/shirts4mike/shirt.php on line 10

I have did a bit of research and see that one possible solution is that there should be no white spaces, however I don't have any spaces!

Ok I have found solution which basically solves the problem. After my first <?php I have put ob_start(); and just before my closing ?> tag I've put ob_end_flush(); It works although I should really read up on why it works.
