Introduction
The Select Boxes package was created to provide an easy way to create the data used in select boxes on HTML forms. The package also helps dry-up your code by encapsulating select box data within dedicated re-usable classes.
Example Problem
It can be a pain when dealing with forms that require multiple select boxes, as the select boxes that are defined in the create() method also have to be re-defined within the edit() method of a controller. With the example below, you would also need to import 5 eloquent models: Artist, Genre, Label, Format, Tag. This starts to become messey.
use App\Models\Artist;
use App\Models\Format;
use App\Models\Genre;
use App\Models\Label;
use App\Models\Tag;
public function create()
{
return View('cms.basedata.tracks.create', [
'selectBoxes' => [
'artistList' => Artist::orderBy('artist_name')
->pluck('artist_name', 'id')
->toArray(),
'genreList' => array_merge(
[0 => 'Please Select...'],
Genre::orderBy('genre')->pluck('genre', 'id')->toArray()
),
'labelList' => array_merge(
[0 => 'Please Select...'],
Label::orderBy('label')->pluck('label', 'id')->toArray()
),
'formatList' => array_merge(
[0 => 'Please Select...'],
Format::orderBy('format')->pluck('format', 'id')->toArray(),
),
'tagList' => Tag::orderBy('tag')->pluck('tag', 'id')
]
]);
}
Example Solution
The above example can be refactored to the following when using the Select Boxes package:
// The model import use statements are no longer needed.
public function create()
{
return View('cms.basedata.tracks.create', [
'selectBoxes' => $this->selectBoxes->get(),
]);
}
Installation
The package can be installed via composer using the following command:
composer require webdevjohn/selectboxes
Usage
You can create a select box group, or use the SelectBoxService directly.
Creating a Select Box Group
Create a select box group when multiple select boxes are needed on a form. This can help DRY up your code, as the select box group can be re-used when creating and updating records (e.g. the create() and edit() methods of a controller).
Run the following artisan command to create a select box group:
php artisan group:make {name}
By default, the newly created group will created in:
App\Services\SelectBoxes\Groups
You can override the default namespace by specifying an optional 2nd argument when creating a group:
php artisan group:make {name} {namespace}
Defining Select Boxes
namespace App\Services\SelectBoxes\Groups;
use App\Models\Artist;
use App\Models\Format;
use App\Models\Genre;
use App\Models\Label;
use App\Models\Tag;
use Webdevjohn\SelectBoxes\SelectBoxService;
class DemoSelectBoxGroup extends SelectBoxService
{
public function get(): array
{
return [
'artistList' => $this->createFrom(Artist::class)
->display('artist_name')
->orderBy('artist_name')
->asArray(placeHolder: false),
'genreList' => $this->createFrom(Genre::class)
->display('genre')
->orderBy('genre')
->asArray(),
'labelList' => $this->createFrom(Label::class)
->display('label')
->orderBy('label')
->asArray(),
'formatList' => $this->createFrom(Format::class)
->display('format')
->orderBy('format')
->asArray(),
'tagList' => $this->createFrom(Tag::class)
->display('tag')
->orderBy('tag')
->asArray(placeHolder: false),
];
}
}
Available Methods
| Method | Method Type | Arguments | Returns |
|---|---|---|---|
| createFrom() | Mandatory | $model string - fully qualified class name | SelectBoxService |
| display() | Mandatory | $optionText string - the text that is displayed for a select box option $optionValue string - the value of a select box option (default = "id") |
SelectBoxService |
| where() | Optional | $column string - name of the column to filter $operator string - the comparison operator $value string - the value |
SelectBoxService |
| orderBy() | Optional | $orderBy string - name of the column to order by $sortOrder string - sort order (default = "desc") |
SelectBoxService |
| asArray() | Optional* | $placeHolder bool - include a placeholder (default = "true") $placeHolderText string - (default = "Please Select....") |
Array |
| asJson() | Optional* | $placeHolder bool - include a placeholder (default = "true") $placeHolderText string - (default = "Please Select....") |
String (JSON) |
*note. either asArray() or asJson() must be called in order to return results.
Using a Select Box Group
You can use constructor or method injection to inject a Select Box Group.
public function __construct(
protected DemoSelectBoxGroup $selectBoxes
) {}
Then use the get() method on the $selectBoxes instance variable to create the select boxes.
public function create()
{
return View('cms.basedata.tracks.create', [
'selectBoxes' => $this->selectBoxes->get(),
]);
}
This will push the data to the view in the following format:
array:1 [▼
"selectBoxes" => array:5 [▼
"artistList" => array:1378 [▶]
"genreList" => array:12 [▶]
"labelList" => array:484 [▶]
"formatList" => array:4 [▶]
"tagList" => array:26 [▶]
]
]
Acessing Select Boxes Within a Blade File
<label for="genre_id">Genre: </label>
<select name="genre_id">
@foreach($selectBoxes['genreList'] as $key => $value)
<option value="{{$key}}" {{ (old('genre_id') == $key) ? "selected='selected" : ""}}>{{ $value }}</option>
@endforeach
</select>
