php not working??

As stated in http://php.net/manual/en/function.header.php :

Remember that header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP.

I can see from your code snippet that you've already sent output (the </form> tag etc count as output), so trying to send a header at that point won't work.

If you really do want to use the header function, you'll need to move the code so that it is run before output is sent.

Thanks, that makes perfect sense. I did that.

It still fails & gives a blank page.

I'm at a total loss.

Thanks

That link is not giving me a blank page - it's giving me the following message:

FPDF error: Unable to create output file: https://home/lakoshva/summsp/summary.pdf

Hmmm. Now it is giving me a blank page, but if I check the source of that blank page, I see 3 empty lines, which may prevent the header() call from working (blank lines count as output!)

Something to think about that can often cause the blank lines - don't add the closing PHP tag at the end of your scripts! Just leave of the ?> from the end of all your scripts that you include - they're often the reason you get blank lines and this causes you hours of hunting around for bugs, particularly when you're trying to call the header() function.

I fixed the issue with the error you got earlier.

I removed the closing ?> tag from all 7 of the include files.

It now shows 3 blank lines at the top when I view source, so of course, that is PROBABLY the WHOLE problem.

I'll see if any of the includes themselves that includes.

Thanks, I think we are closer.

Chris,

I removed the closing tag in on other file included in one of the included files.

There are still two blank lines at the top on view source.

If there is a blank line in any of the included php files, can that cause this?

Just a plain blank line?

Thanks

Yes, blank lines before a <?php tag cause the problem too.

Any blank lines outside of the PHP script will be output as blank lines in the file (before and after)

I found the last two blank lines source & fixed.

Now the problem is totally different; it appears to be in an infinite loop.

Aaaaaaaaaaaarrrrrrrrrrrrrrrggggggggg!!!
