Passing Variables and redirection
11 June 2010 at 12:24pm Last edited: 11 June 2010 12:36pm
Is it possible to write a method that redirects to another page and for that method to also return a variable to the call.
In the attempt below I am attempting to pass the variable $status back to the page being redirected to.
I know this could be accomplished with session variables. But I wondering if there is better solution.
Thanks in advance.
----------
function doAddStudent($data,$form) {
// create student data object
$student = new student();
$form->saveInto($student);// check for matches
$dupe = DataObject::get('Student',
"`Lastname`='".Convert::raw2sql($student->Lastname)."'");
// && `FirstName`='".Convert::raw2sql($student->FirstName)."'"// Debug::show($dupe);
if (!$dupe) {
$student->write();
$status='Record Saved';
$this->redirect('..');
}
else{
$status='Record not saved: Duplicate exists'
$this->redirectback();
}
} -

If you are using the built in form validation you can do $form->addErrorMessage('Message', 'This is an error', 'bad'); before your redirect back which will pass the error message via the Session class.
Or you can use the Session class directly to save the value, get the value http://doc.silverstripe.org/sessions
