place your function call outside of all brackets

Thank you that worked.. I have a problem now when you press the submit button on the form, it renders the form twice, or if you fill out the information i'm getting headers already sent.. I know it must be down to my if statements somewhere.

may i ask why you have an entire document stored in a function?

typically not a good idea.

you receive a header error because you are trying to use the header function after you have already sent output to the browser.. this will not work.

kamal213 · October 27, 2011

I agree with AyKay47. I think you should put your php script above the html tag rather than below the end of the html tag

djdoogle · October 27, 2011

Hi thanks for the reply, On a tutorial it told me to put the html into a function so that renderform function is called a couple of times. I did have it working at one point but now it's not working properly.
