How to use the getAllData() function? - atk4

Question

After I added a form and loaded some data,
$f=$this->add('MVCForm');
$f->setModel('Model')->loadData(1);
$data=$f->getAllData();
the data do show up in the fields of the form, however, the $data is empty. I thought it would be the data array for the fields show up in the form. Did I miss something here?

Answer 1

i don't know the reason behind the design or functional behavior of this,
but you need to call the form's loadData() first.
Modifying the code you provided:
$f=$this->add('MVCForm');
$m=$f->setModel('Employee')->loadData(1);
$f->loadData(); // add this call
$d=$f->getAllData();
$b=$this->add('Button')->set('Show Me The Data');
$b->js('click')->univ()->alert(var_export($d,true));
so you can retrieve the data loaded by the model.
i am guessing that this function prepares the form's fields prior to a call to getAllData()
or maybe there is a shorter way, ATK has TONS of hidden secrets. :)

You need to use that inside isSubmitted() function. isSubmitted will automatically call the loadData(). Here is typical use:
$form=$this->add('Form');
$form->addField('line','test');
$form->set('test','default value');
$form->addSubmit('Show me the data');
if($form->isSubmitted()){
$data = $form->getAllData();
$form->js()->alert(var_export($d,true))->execute();
// execute at the end is important!
// it will also stop execution.
}
$this->add('OtherElements'); // other stuff on the page,
// which we don't need for form submission logic
