I am creating a simple form. I would like to use embedded javascript to validate that the form is filled out and then, if it turns out to be valid, process the data with a php script.

I don’t know how to do this, because I don’t know how to associate more then 1 script with a form.

<form id="aform" name="aform" action="myvalidationscript.js" method="POST" onSubmit="return checkForm()">

will get my form validated and only send the date if it is valid, but how do I get it to understand that there is a PHP file on the server that wants to accept the data and do something with it?

Either this is possible and I don’t know how to do it, or I have the model for validation all wrong. I recognize that I could do the validation in the same PHP file as the processing, but I would like 1) the option to organize my code by functionality a little better than putting everything in one script, and 2) the option to validate client-side with some embedded javascript.

Any suggestions?

    Never trust the client-side. You should have all your validation logic on the server-side in php. On the client-side you could add validation logic simply to enhance the user experience.

    In addition, the action attribute specifies the URL of the server-side script that should handle the completed and submitted form. It is not there to associate a client-side script with your form.
