choices type field not populating value about laravel-form-builder HOT 14 CLOSED

When you pass the model, you have to manually assign choices:

<?php
    $this->add('fields', 'choice', [
        'choices' => $this->model->fields,
        ...
    ]);

No,No,,,, how to populate the values that are saved for editing

from laravel-form-builder.

I don't understand your question. When the form is submitted, you should receive selected data in Input::get('fields'), and you handle them after.

ya.. I got that but in edit form how to populate selected values in 'choice' type using model.Means,if I want to pass default value as $model->id = 1,it displays in the form but $model->fields = ['choice1'], not displaying in the form,not showing selected choice,choice1

from laravel-form-builder.

I'm not 100% sure, but i think that Laravel's form builder does not support automatically checking multiple values. You can try to put like this:

<?php
    $this->add('fields', 'choice', [
        'choices' => $this->model->getAllPossibleFields(),
       'selected' => $this->model->fields
    ]);

selected property holds the keys of all selected values, so if you have ['choice1 => 'some choice', 'choice2' => 'some other choice'], if you want them to both be selected you put:

<?php
'selected' => ['choice1', 'choice2']

Thank You,,, what I need was this 'selected' => $this->model->fields

from laravel-form-builder.

Great. It should be automatic, but i think that works only when there is one selection.

from laravel-form-builder.

it works for multiple selection too...

from laravel-form-builder.

But, how this 'selected' => $this->model->fields can be use for subforms,,Subforms generate field name as name="subFormClassName[field]"????

from laravel-form-builder.

Same way, when you initialize it, pass model and use it.

from laravel-form-builder.

if sub form attributes are the attributes of a model then how value can be populated. subFormClassName[field] is the attribute of model. $model->subFormClassName[field] = "value".

from laravel-form-builder.

I think just passing the model to the subform should work.

<?php
$this->add('sub_form', 'form', [
    'class' => \FormBuilder::create('Forms/SubForm', ['model' => $this->model])
    // ...
]);

from laravel-form-builder.

but passing value like this $model->subFormClassName[field] = "value" is not populating in the form

from laravel-form-builder.

yes, it's not working that way. It's not supported that way by laravel form builder class.
