Hi all ,
The following code first checks if the user is authorised, then it checks for a button press and executes the code if the button if pressed. It then checks for a result and if there is a result (in the update query) it shows the confirmation page.
My problem is that the code within the button press seems to run whenever the page is called as PHP is report a lot of undefined variables. When i do press the button it all executes as it should, handling the images as expected however the final 'result' page shows as an entirely new page below the current one in the browser and not on its own. I have tried putting a couple of 'else' statments in with the 'if's and some else statments on their own but i must be doing it wrong because i constantly get an 'unexpected else' error.
Can anyone point me in the right direction with this please?
