Header

[mark_kccs]

Hi
I am using the header('location:... ') function in a script which works fine on my local pc but not when I call the script from my ISP? Any suggestions as to the possible cause.

Many thanks

The most common cause is something causing output to be sent (even if it's just a blank line or space) before the header() call. It should throw an error if that's the case, so you might want to turn on all error reporting to find out. Just add the following either at the start of your script or at least before the the header() call:

ini_set('display_errors', 1); // change to 0 for production version
error_reporting(E_ALL);

Hi NogDog

Thanks for the reply. I do have error reporting turned on in my php.ini but I added your lines to make sure and this is the bit I cannot work out as again the script works fine on my home pc. It's only when I upload and call it over the web that this error shows?

Thanks

Do you use a full URI ("http://yadda.yadda.yadda...") rather than just a relative path? Normally it does not matter, but the HTTP 1.1 specification does state that the Location header must be a full URI. Just grasping at straws here with nothing else to go on; if you're not getting any error messages, it's pretty hard to debug in the blind. 🙂
