Header Error


dsjoes

i get the below message when i try to use the script near the bottom which deletes from an sql database and the linked file but if i put the script on a page on it's own it works without a hitch. so it is something else on his page that is causing the problem i have tried removing everything but the main design but it is then indicating the error is because of the divs i have used and every time i remove the one it wants it changes to another.

The reason for that error is because you have already began outputting HTML code so redirecting after that point is not possible. You can move your whole PHP code block to the top before you begin your HTML output and it should work.

Hi!What you need to do is create an intermediary script that either outputs the header to redirect to index.php or include another file that contains the markup with the stylesheet or anything else that you choose to include. This approach will not only fix the problem that you are experiencing but will also make your code better organized (and I'm sure folks would want to debate on that bit... what constitutes a good design is something fairly subjective).If you do need more help with the problem, feel free to reply or send me a private message/email/instant message and I'll try to get back to you as soon as I can.

thanks that worked

Another solution is to start using output buffering, which will send the produced output only the php script stops executing or when you tell it to do it.All you need is to use ob_start() function: http://de1.php.net/manual-lookup.php?pattern=ob_startWith〈=en&scope=404quickref the combination of ob_* functions, you can make a lot of things quite easily, it lets you control your content and you can start using GZip as a handler for output buffering, but to use it right, I would suggest to read a little bit on this subject - PHP output buffering.


dhi

you cant set header - location inside the body part. you will find this script running perfectly if you set the php code before the body begin.
