Invoke php from javascript function

[ibeck]

How can I invoke a php script from a javascript function and pass variables to the php script (bi-direct)?

If by invoke you mean that you call a php script page and load it then:

function blah(pass) {

document.location = "something.php?var=" + pass

}
<or something to that effect>
This would load the page. When the function would called. However if you mean running a script "behind" the page when a function is called... then it cannot be done. Javascript is a client side language and PHP is serverside. The only thing you could possibly do if you want it to load in the back, is use Flash or a Java Applet or something.

Hope that Helps!

Thanks Nashirak.

Yes, I want to load / run it in the back. Can it be done otherwise (i.e. without JavaScript and in plain HTML)?

Not really... the only thing you could do is use the $PHP_SELF variable, but this would send whatever you changed on the page back to the page itself and the user would see it load (the page) again.
