php code working on local server but not on public server

flunn · April 30, 2009

I have a page on my website which includes a form-based quiz, coded in php, that works properly on my local (MAMP) server but not on my public server.

The quiz is supposed to work in the following way:

The user answers the questions by typing into text boxes and then clicks on a “submit” button. The quiz reappears with the answers intact but with the background colors of the text boxes changed to green or red depending on whether the questions are answered correctly or incorrectly. This works properly on the local server, but on the public server, the first time the button is clicked, the quiz simply reappears without the background colors changed. When the button is clicked for a second time, everything works as it’s supposed to and continues to do so until the browser is closed. When the browser is reopened, the problem reappears.

I have contacted the support people at the public server but they have been no help so far.

Any ideas on what might be causing this or on how it might be fixed would be much appreciated.

regards to all from flunn
