Ajax

$('.button.update.user').click(function(){
var userID = $(this).data('user-id');

$.get(
    site_url + userID,
    function (users) {
        $('#firstName').text(user.test_first);
        $('#lastName').text(user.last_name);
    }
    ),
$.ajax({
    dataType: "json",
    data:
        'act=edit' + 
        '&userID=' + userID,
    type: 'post',

});
})

PHP

class Application_Controllers_Test_Module extends Application_Controllers_ModelResource {
public function indexAction() {
    // $data['test'] = $this->getConfig()->read($this->getDispatcher()->getServiceKey());
    $testModel = Application_App::getModel("test");
    $act = $this->getRequest()->getParam("act");
    $userFirst = $this->getRequest()->getParam("firstName");
    $userLast = $this->getRequest()->getParam("lastName");
    $userID = $this->getRequest()->getParam("userID");
    if($act == 'add') {
        $result = $testModel->AddingTestUsers($userFirst, $userLast);
        Application_App::redirect('test');
    }
    if($act == 'getUser') {
        $data["users"] = $testModel->selectUserByID($userID);
        echo json_encode($teacher);
    }
    if($act == 'edit') {
        $result = $testModel->UpdateTestUsers($userFirst, $userLast, $userID);
    }
    if($act == 'delete') {
        $result = $testModel->DeleteTestUsers($userID);
        die(json_encode($result));
    }
    $data["users"] = $testModel->selectTestUsers();

    return $data;
}
}

## MySQL ##
public function selectUserByID($userID) {
    return $this->getAdapter()->fetch("SELECT * FROM test WHERE 'test_id'=?", array($userID));
}

</div>

Answer 1

To connect AJAX to a PHP script you have to specify the URL in your AJAX call along with a method:

$.ajax({
    method: 'post',
    url: 'foo.php',
    dataType: "json",
    data:
        'act=edit' + 
        '&userID=' + userID,
});
