Remove field from Collection

[uovidiu]

How can I remove a field from AddressForm?

Here is my structure

class ClientForm extends Form
{
    public function buildForm()
    {
        // Add fields here...

        $this

            ->add('company_name', 'text', [
                'rules' => 'required|min:5',
            ])

            ->add('first_name', 'text', [
                'rules' => 'required',
            ])
            ->add('last_name', 'text', [
                'rules' => 'required'
            ])
            ->add('service_charge_rate', 'number', [
                'rules' => 'required'
            ])
            ->add('late_fee_amount', 'number',[
                'rules' => 'required'
            ])
            ->add('minimum_balance', 'number',[
//              'rules' => 'required'
            ])

            ->add('addresses', 'collection', [
                'type' => 'form',
                'property' => 'id',
                'prototype' => true,
                'wrapper' => ['class' => 'form-group grid-3_xs-1'],
                'options' => [    // these are options for a single type
                    'class' => AddressForm::class,
                    'label' => false,
                    'wrapper' => array('class'=> 'col'),
                ],
                'label_show' => false,
            ])
        ;

        $this->add('submit', 'submit', [
            'wrapper' => [ 'class' => 'clearfix'],
            'attr' => [
                'class' => 'btn btn-primary btn-block'
            ]
        ]);

    }
}

AddressForm.php

use Kris\LaravelFormBuilder\Form;
use Webpatser\Countries\Countries;
use Lecturize\Addresses\Models\Address;

class AddressForm extends Form
{
    public function buildForm()
    {
        // Add fields here...

        $this
            ->add('street', 'text', [
                'rules' => 'required',
            ])

            ->add('city', 'text', [
                'rules' => 'required',
            ])

            ->add('state', 'text', [
                'rules' => 'required',
            ])

            ->add('post_code', 'text', [
                'rules' => 'required',
            ])

        ;
    }
}

I've tried $form->addresses->removeChildren('post_code') but doesn't work.

Is it possible? Because on a child element of type 'form' works without a problem.

@uovidiu since collection is array of forms, you need to provide the index of the field that you want to remove. So if you need to remove 2nd entry, something like this should work:

$form->addresses->removeChild(1);

Also note that i used removeChild, since removeChildren does not exist.

Still doesn't work. I get that I need to pass the index. $form->addresses->removeChild(0); result in an empty form.

Everything else than 0 doesn't do anything.
