I need to assign several default values to select multiple tag. At the moment, I managed to assign only one value with

$tag->setDefault('element[]', 'value');

If I try to pass array as value, it tells me that only scalar values are allowed. Any way to achieve that?

Solved it via Phalcon\Forms\Element\Select()->setDefault(array())

        $tag = new Select('element[]', array(1,2,3,4,5), array(
            'useEmpty' => false,
            'multiple' => true
        ));

        $tag->setDefault(array(1,4));

Nope, that doesn't works... Here's the code from view:

{{ select("estate_types[]", estate_type, "using": ["id","name"], "useEmpty":false, "multiple":true) }}

And from controller:

$this->tag->setDefault('estate_types[]', array(1,2));

This gives me that:

Phalcon\Tag\Exception: Only scalar values can be assigned to UI components

How to apply it?

For others returning to this question, the only setDefault in the system which complains about arrays is the setDefault associated with tag: https://github.com/phalcon/cphalcon/blob/107b6f0197b0464d9f6b11ff390a560c000bf448/phalcon/tag.zep#L252 You can work around this and use chebureque's hacky solution, or you can use tag's setDefaults (plural) which is designed for working with arrays. It also accepts a second parameter in case you want to array_merge the array previously set
