php - Use data attributes in laravel form select

Solution:

The best way to set the custom value to the form::select is by using the attribute parameter of form::select function.

controller.php

$contact_options = Contact::all();

$contact_attributes = $contact_options->mapWithKeys(function ($item) {
    return [$item->id => ['data-otherInfo' => $item->otherInfo]];
})->toArray();

$contact_options = $contact_options->pluck('name', 'id')->toArray();
Copy code

blade.php

{!! Form::select('contact_id', $contact_options, old('contact_id', null), ['class'=>"form-control", 'id'=>"contact_id", 'required' => 'required'], $contact_attributes) !!}
Copy code

Solution:

For this requiment you need to create the<option> with loop and simply html

<select name="amount_of_days" placeholder="Amount of days">
    @foreach($days as $val)
        <option value="{{ $val['id'] }}" data-days="{{ $val['days'] }}"> {{ $val['name'] }}<option>
    @endforeach
</select>
