Help with Form and postback

[BrianBurgit]

I am new to PHP. I have a form with several HTML input fields for the user to fill in. One of those fields is for the user to enter an amount. I have a HTML input field of type image. When the image is clicked, I want to populate another input field, type text, with an amount I calculate using the amount entered by the user and some math I do in a Javascript function. This all works, except clicking the image causes a postback, and the calculated amount is then gone.

Is what I am attempting to do correct?

Thanks,

Brian

it sounds like you are not doing anything that involves php.

i would bet that you are using an <input type=image> tag rather than an <img> tag. the latter would not cause the form to submit whereas the former would.

you can attach an onclick event to the <img> tag in javascript.

Ha! You are correct, that was the problem.
