Adding data before save in CakePHP

Question

Post hasMany Tag: My form:

$form->input('Post.title');
...
$form->input('Tag.0.name'); //1st tag
$form->input('Tag.1.name'); //2nd tag

This works perfectly, but...

I create some fields Tag.n.name, and I want add each time one tag by $this->data['Tag'][some_number]['name'] = 'all';
Do not ask me why i want that, but tell me how i can add 'all' tag in my model to each Post?

This should get effect 4 INSERT sqls: one add post, and three: 1st tag, 2nd tag, all tag.

More explain: How add more tags without form fields? How add default tags? No input hidden, only pro solutions:)

Answer 1

$this->data['Tag'][] = array('name' => 'all');

Put this either in your Controller before saving $this->data or in the Model's beforeSave() callback.

Answer 2

Thanks for reply...

In Controller this works, I want use this in beforeSave, but this not work, why?
