Problem: Javascript & PHP form with HTML_QuickForm

[Ronan]

Hi,

I have a problem with a form using the PHP PEAR HTML_QuickForm package &
javascript:

I want to record the content of my form into a mySQL database then
execute a javascript function.

My problem is that javascript is executed before the mySQL insertion.
I actually need the mySQL insertion first, since my javascript function
is supposed to close the window...

Thanks for your help.

A short explanation of my code:
#--- 1 ---
#javascript function
#---------
#--- 2 ---
# javascript is called by the action field of my form

# PHP code
$form = new HTML_QuickForm( 'createNewsCate goryForm',
'post','javascr ipt:addValue(); ');

# HTML result
<form action="javascr ipt:addValue(); " method="post" ... >
#------
#--- 3 ---
# form validation du formulaire and insertion into the mySQL database:
if ($form->validate()) {
$form->process('dataP rocessing', false);
}
else {
$form->display();
}

function dataProcessing( $values){
#mySQL Insert request
}
#---------
