Installation

composer require abdallahmohammed/laravel-multistep-forms

Example Usage

use AbdallaMohammed\Form\Form;
use Illuminate\Support\Facades\Route;

Route::get('form', function () {
    return app(Form::class)->make(function (Form $form) {
        // Create a step instance and define rules, messages and attributes
        $form->step()->rules([
            'name' => ['required', 'string'],
        ])->messages([
            'required' => ':attribute Required',
        ])->attributes([
            'name' => 'Name',
        ]);

        // Add another step with dynamic rules
        $form->step()->dynamicRules();
    });
})->name('form');

Steps Usage

Before Step

Define a callback to fired before a step has been validated.

Return a response from this hook to return early before validation occurs.

before($step, Closure $closure)

$step could be Step instance, or the number of the step.

After Step

Define a callback to fired after a step has been validated. Step Number or * for all.

Return a response from this hook to return early before the form step is incremented.

after($step, Closure $closure)

$step could be Step instance, or the number of the step.

Dynamic Step

You can set a step as dynamic, so the step will take it's rules, messages and attributes from the request.

For example

use AbdallaMohammed\Form\Form;
use Illuminate\Support\Facades\Route;

Route::get('form', function () {
    return app(Form::class)->make(function (Form $form) {
        ...
        $form->step()->dynamicRules()->messages([
            'foo' => 'bar',
        ]);
        ...
    });
})->name('form');

From the example we have defined the attributes without the rules, so we must send the rules with the request. Here it is the example of the request body.

{
  "step": 1,
  "1.rules": {
    "name": ["required", "string"]
  }
}

1.rules is a reference to first step rules.

You can change 1 to the number of the dynamic step.

As the previous example you can send 1.messages and 1.attributes in the request body.
