Laravel Custom Fields for Laravel 8

⚠️ Warning: these docs are incomplete and may reference unsupported functions. This is a pre-release version that is not yet ready for production use.

Just a fork of givebutter/laravel-custom-fields tagged for Laravel 8

Laravel Custom Fields is a package that allows you to add custom fields to any Laravel model and associate responses to those fields with other models.

Installation

To get started, add the givebutter/laravel-custom-fields package to your composer.json file and update your dependencies:

composer require givebutter/laravel-custom-fields

Publish the migration:

php artisan vendor:publish --provider="Givebutter\LaravelCustomFields\LaravelCustomFieldsServiceProvider" --tag="migrations"

Run the migration:

php artisan migrate

You can customize the table names using configuration options. More on that later.

An example - Survey App

For the purposes of the documentation, lets use the example of a Survey building app. Administrators might use a backend to create Surveys full of questions and end users might then fill out those surveys, generating SurveyResponses.

Preparing your models

Adding custom fields

To add basic custom field support, simply add the HasCustomFields trait at the top of your model:

use Illuminate\Database\Eloquent\Model;
use Givebutter\LaravelCustomFields\Traits\HasCustomFields;

class Survey extends Model
{
    use HasCustomFields;

    // ...
}

Adding custom field responses

Next, we add support to store custom field responses. We'll simply pull in the HasCustomFieldResponses trait at the top of our SurveyResponse model.

use Illuminate\Database\Eloquent\Model;
use Givebutter\LaravelCustomFields\Traits\HasCustomFieldResponses;

class SurveyResponse extends Model
{
    use HasCustomFieldResponses;

    // ...
}

Basic usage

Creating fields

You can add a field to a model like this:

$survey->customFields()->create([
    'title' => 'What is your name?',
    'type' => 'text'
]);

Each field can contain the following: (More on these later)

title : The title / question of your custom field. description : The description of your field. Useful for providing more context to user filling out fields. type : The type of field you're creating. Available types are outlined in the next section. required : A boolean representing whether a field is required or not. answers : An array of acceptable values for fields that have user-selection.

Creating field responses

To store a response on a field, you can do this:

$field->responses()->create([
    'value' => 'John Doe'
]);

Retrieving fields

To retrieve custom fields, use the customFields relation:

$survey->customFields()->get();

Retrieving field responses

To retrieve the responses on a field, use the responses() relation:

$field->responses()->get();

Custom field types

Custom fields may be any of 5 types:

• text : Free entry fields which are stored as strings. Use these for simple inputs as they have a max-length of 255 characters.
• textarea : Free entry fields which are stored as text columns. Use these for longer bits of text that may not fit within the text field.
• radio : These are multi-select fields, which require you to pass an answers property.*
• select : These are multi-select fields, which require you to pass an answers property.*
• checkbox : Boolean fields.

In general, these field types correspond to their respective HTML elements. In the future we may provide front-end scaffolding for these fields, but for now, that's up to you.

*The radio and select field types require you to fill the answers property on the field. This is a simple array of strings, which are valid responses for the field. For example:

$survey->customFields()->create([
   'title' => 'What is your favorite color?',
   'type' => 'select',
   'answers' => ['Red', 'Green', 'Blue', 'Yellow'], 
]);

Validating responses

Validation helpers

In most cases, you'll want to validate responses to your custom fields before saving them. You can do so by calling the validateCustomFields() function on your model:

$responses = [
    '1' => "John Doe",
    '2' => "Blue"
];
$survey->validateCustomFields($responses);

You can also pass in a Request object:

use Request;

class FooController extends Controller {

    public function index(Request $request) 
    {
        $validation = $survey->validateCustomFields($request);

        // ...
    }

}

<form>
    <input type="text" name="custom_fields[]" />
</form>

When using a Request object, the input key should be an array of values

Implicit validation rules

The 5 supported field types described above automatically have the following validation rules applied to them:

• text : string|max:255
• textarea : string
• radio : string|max:255|in:answers
• select: string|max:255|in:answers
• checkbox: in:0,1

Important: when using checkboxes, it is important you POST unchecked boxes as well, otherwise your response data may be incomplete.

Required fields

Because of how common they are, required fields have native support in this package. To mark a field as required, simply set required to true when creating a custom field.

$survey->customFields()->create([
    'title' => 'Do you love Laravel?',
    'type' => 'radio',
    'answers' => ['Yes', 'YES'],
    'required' => true
]);

Custom validation rules

Along with the built in validation rules, you can apply your own rules to the any custom field. For example, if you wanted to validate a field was an integer between 1 and 10, you could do the following:

$survey->customFields()->create([
    'title' => 'Pick a number 1-10',
    'type' => 'text',
    'validation_rules' => 'integer|min:1|max:10'
]);

Remember, the validation_rules supports any of the available validation rules in Laravel.

Validation Rule Sets

-> nah? In some cases, it's easier and more practical to define validation rules sets. For example, in our Survey app, if we wanted to offer a

Saving Responses

To store responses to custom fields, just call saveCustomFields() and pass in an array of values

The saveCustomFields function can take in a Request or array.

$surveyResponse->saveCustomFields(['
   
']);

If you're submitting a form request, you can easily:

Use App\...
$surveyResponse->saveCustomFields($request->input);

Querying responses

You can query for responses on any field by using the WhereCustomField() scope. The function takes in the field object and the value you're looking for. To learn more about query scopes visit this link.

For example, if you wanted to find all SurveyResponses with a large T-shirt size, perform the following query:

Use App\Models\SurveyResponse;
Use App\Models\SurveyResponse;

$field = 

SurveyResponse::WhereCustomField($field, 'large')->get();

Ordering

You can change the order of custom fields on a model by using the order function. Pass in either an array or Collection of ids. The index position of the field represent the order position of it.

$survey->orderCustomFields([2, 4, 5]); // Field with id 2 will be ordered first.

You can also manually change the value of the order column:

$field->order = 3; 
$field->save();

By default, custom fields are returned in ascending order when retrieved via the relation:

$survey->customFields()->get(); // Returned in ascending order.

Configuration

To publish the configuration file, run the following command:

php artisan vendor:publish --provider="Givebutter\LaravelCustomFields\LaravelCustomFieldsServiceProvider" --tag="config"

The configuration file should now be published in config/custom-fields.php. The available options and their usage are explained inside the published file.
