Form submit to run javascript and then post to php script

rated 0 times [ 84] [ 6] / answers: 1 / hits: 24973 / 13 Years ago, sun, february 26, 2012, 12:00:00

I am currently working on a php/html/javascript project. I have a form where when the user presses the submit button, it should run a javascript function and then afterwards post to a php page to process the data that was submitted in the form.

I have the form run a javascript method as below

<form class=form id=addImageForm name=addImageForm action=javascript:validateAddImage(); method=post>

The method validates the form, calls another method and then it submits the form using document.myForm.submit();

How do I get it to submit the form to another php page to process the data including upload selected files.

Thanks for any help you can provide.

Set yout 'action' parameter to your PHP script, and do any javascript procesing in a javascript event.

<form class=form id=addImageForm name=addImageForm action=processing.php method=post onsubmit=return validateAddImage();>

Then in your js validation, return 'true' if everything's fine, or 'false' if not. Returning 'true' means 'continue with the submit process and send over data to processing.php
