Question

if(isset($_POST['submit2']))
{
if($_POST['linklabel'] == '')
{
    header('Location: index.php?VIEW=BLAH&message=failure');
}
else
{

Here is my code, it is giving me the typical redirect error of :
Warning: Cannot modify header information – headers already sent by (output started at /home/content/74/8256574/blah/blah/index.php:24) in /home/content/74/8256574/blah/blah/blah/blah.php on line 14.

The header redirect above is what is on line 14. On line 24 of the index.php page, there is a css file (don’t think that would be causing the issue..).

I am submitting a form, and checking the form for empty values. If it finds an empty value, redirect to above URL with &message=failure

I know there are a lot of questions on here asking the same thing but I still can’t solve my issue. Please, any help would be great.

Answer 1

If data has been sent to the browser, you can not modify header info. Simple fix is to buffer the output.

ob_start(); // Put at the top of your script.
header('Location: index.php?VIEW=BLAH&message=failure');
ob_end_flush();
