Question

I am on CakePHP 1.2 at the office and, following my last question, I would like to send the array key of the selected option in a SELECT input instead of sending its actual value. I have tried a few things with the Model::beforeSave() function, without success.

I am aware that the data posted by CakePHP does not include the whole array, but only the selected value.
Here is what the function looks like at the moment:

function beforeSave(){
    $this->Post->set('category_id', = array_keys($this->data['Annonce']['category_id']);
    # debug($this->data);
}

Would there be a way to store the array keys into an hidden input and changing this input value depending on the user’s selected item in the SELECT input, and to also omit sending the user’s input but still send the hidden value?

Answer 1

$categories = Set::combine($categories,'{n}.categories.id', '{n}.categories.nom');

This did it for me… CakePHP assigns the array_keys() values automatically to the value field of the input.
