Once your php page has loaded, there’s no going back. The best way to go about passing variables ( data ) back to the server is with ajax, so it might be time to brush up on ajax http://api.jquery.com/jQuery.ajax/

Update: Tell you what, here is what a really basic ajax call looks like, notice that is send data to the server here with POST:

 $.ajax ( {type : 'POST' ,
    url : 'email.php' ,
    data : { variable: variable, anotherVariable: anotherVariable } ,
        success : function ( data ) { $('#some-div').html ( data ) ; }
    } ) ;
