Hello

In the following form, phone type and phone number can appear an infinite number of times (the "Add" link is handled by Javascript):

How am I suppose to code this with Phalcon, both when saving a new record (start with one empty phone number) and when editing an existing one (start with x existing phone numbers)?

class MyForm extends Form
{
    public function initialize()
    {
        $field = new Text('name');
        $field->setLabel('Name');
        $this->add($field);

        $field = new Select('phone_type',
            Models\PhoneLineType::find(),
            ['using' => ['id', 'name']]
        );
        $this->add($field);

        $field = new Text('phone_number');
        $this->add($field);
    }
}

// View
foreach (?? as ??) { ?>
    <div>
        <?= $form->render('phone_type') ?>
        <?= $form->render('phone_number') ?>
    </div><?php
}

Thanks in advance!

public function initialize($obj = null, $options = null)
{
    if($obj)
    {
        for($i = 0; $i < count($obj->number); $i++)
        {
             $field = new Select('phone_type'.$i,
            Models\PhoneLineType::find(),
            ['using' => ['id', 'name']]
            );
            $this->add($field);

        }
    }
}

something like that =d

Just ideas not sure these work, make the name an array, pretty standard PHP stuff like:

$field = new Text('name[]')

You'll get an array when posted yes? You can then sanitize, validate them separately, something like the first example here: https://docs.phalcon.io/en/latest/reference/validation.html

But instead of $_POST, its the $this->request->getPost['name']. So the form validation is not part of the form itself, but then I'm not sure how to glue this together. Perhaps you can define a custom validator, also found on that link, but within your custom validation, you place something like whats in the first example code block.
