Adding custom attributes to Select field in laravelcollective HTML
Most of the time we use HTML select without any custom attributes. But in some cases adding custom attributes like data-* helps to easily access extra data related to the Option selected without making additional ajax call.
LaravelCollective HTML is an awesome package to created HTML forms in Laravel. It provides a lot of features to help to build simple and complex forms.
If you wanted to add some custom attributes in Select-Option tag, that is something like this:
|
1 2 3 4 5 |
<select> <option value="1" data-rate=10>Tax-1</option> <option value="2" data-rate=18>Tax-2</option> <option value="5" data-rate=20>Tax-3</option> </select> |
This is easy if you do it using a Loop, but using loops for every select field where you want to add it can be a pain.
Luckily LaravelCollective-HTML has an option for it in "Form::select". So you don’t have to use Loops.
If you look into the Select method signature, it looks like this:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
/** * Create a select box field. * * @param string $name * @param array $list * @param string $selected * @param array $selectAttributes * @param array $optionsAttributes * * @return \Illuminate\Support\HtmlString */ public function select( $name, $list = [], $selected = null, array $selectAttributes = [], array $optionsAttributes = [] ) { } |
The last parameter is where you can pass extra attributes to be added in option tag.
So for the above example, the optionsAttributes parameter will be:
|
1 |
$optionsAttributes = [1 => ['data-rate' => 10], 2 => ['data-rate' => 18], 5 => ['data-rate' => 18] ]; |
For example: If you want to show a list of tax rates:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
//Get all tax the business. $all_taxes = TaxRate::where('business_id', $business_id); //Create an array of option attribute $tax_attributes = collect($all_taxes->get()) ->mapWithKeys(function ($item) { return [$item->id => ['data-rate' => $item->amount, 'data-type' => $item->type ]]; })->all(); In view: Form::select("tax", $all_taxes, null, [], $tax_attributes); |
I hope this small tip is helpful.
Although this option is present but is not described in the documentation so thought of sharing.
