How to set custom data-attribute to option with Laravel Collective
提问by Sredny M Casanova
I have a form, inside I have a select with some options and I'm using Laravel Collective Forms to build it, I have something like:
我有一个表单，里面有一个带有一些选项的选择，我正在使用 Laravel Collective Forms 来构建它，我有类似的东西：
{!! Form::select('size', $data, $selecteds, ['multiple' => true]) !!}
All going well until here, but now I need to set a data-sectionattribute to each option, how can I make it?
一切顺利，直到这里，但现在我需要data-section为每个选项设置一个属性，我该怎么做？

I had to do the same thing recently. After inspecting the FormBuilder class to write my own marco I found out that the select() method actually has an undocumented fifth parameter for option attributes:
我最近不得不做同样的事情。在检查 FormBuilder 类以编写我自己的 marco 之后，我发现 select() 方法实际上有一个未记录的第五个选项属性参数：
Form::select('size', $data, $selecteds, ['multiple' => true], $optionAttributes)
Form::select('size', $data, $selecteds, ['multiple' => true], $optionAttributes)
The index must match the value of the option, e.g.:
索引必须与选项的值匹配，例如：
$optionAttributes = [
'S' => [
'data-title' => 'Small',
'data-surcharge' => '0',
],
'M' => [
'data-title' => 'Medium',
'data-surcharge' => '5',
],
'L' => [
'data-title' => 'Large',
'data-surcharge' => '10',
],
];
So I ended up writing a marco which generates this array based on a collection and then uses the default select() method. Something like that:
所以我最终编写了一个基于集合生成这个数组的 marco，然后使用默认的 select() 方法。类似的东西：
\Form::macro('locationSelect', function ($name, $value = null, $attributes = []) {
// Get all locations from the DB
$locations = \App\Location::all();
// Make an id=>title Array for the <option>s
$list = $locations->pluck('title', 'id')->toArray();
// Generate all data-attributes per option
$optionAttributes = [];
foreach ($locations as $location) {
$optionAttributes[$location->id] = [
'data-icon' => $location->icon,
'data-something' => $location->some_attribute,
];
}
// Use default select() method of the FormBuilder
return $this->select($name, $list, $value, $attributes, $optionAttributes);
});
Very convenient.
很方便。
{{ Form::locationSelect('location_id') }}
{{ Form::locationSelect('location_id') }}

Add it to a 4th argument which is an array:
将其添加到数组的第四个参数中：
{!! Form::select('size', $data, $selecteds, ['data-attribute' => 'John Smith', 'multiple' => true]) !!}
