Not sure why I only thought of this now.
Any form: quick dummy function
function edit() {
If(!empty($this->data)) {
If($this->save());
// whatever
}
$countries = $this->Model->_getCountries(); // returns list of countries
$this->set(compact('countries'));
}
So you have a full list of countries in the form user can select from.
$validate array() in model I have a function to check the country_id value
and that function also uses _getCountries();
public function checkCountryValues( $data, $field ){
$valid = false;
if( !empty( $this->data[$this->alias][$field] ) ) {
if ( array_key_exists($this->data[$this->alias][$field],
$this->_getCountries() ) ){
$valid = true;
}
}
return $valid;
}
So I am essentially grabbing that data twice. How can I reuse that initial
$countries throughout the whole process rather than grabbing the same data
over and over?
Might sounds trivial but some models might have 6 or more related models and
then validating pulling all the same values used in the view / form it is
just added work.
Thanks,
K
