Ajax login script header problem

Question

Hi,

I have a ajax login script, using prototype, where I ajax the credentials over to a php page that checks if the info is correct. If it is, I try to set a cookie and then return 0 or 1 depending if it is correct. The ajax call returns 0 if it is correct and then makes a js call on the original page to redirect into the site. I keep getting a cannot modify header information error. What am I doing wrong?

Thanks

Check that your PHP isn't outputting any content before the line which sets the cookie. This includes whitespace - so make sure your code doesn't look like this:

<!-- some comment, new line, or something else before the php opening tag -->
<?php // This should be on line 1, with no space before it.
