Livewire (Laravel) Get validation error inside controller not the view

Question

I want the errors show of the controller not the View

    public $name;
    public $email;

    protected $rules = [
        'name' => 'required|min:6',
        'email' => 'required|email',
    ];


    public function submit()
    {
        $this->validate();

        Contact::create([
            'name' => $this->name,
            'email' => $this->email,
        ]);
    } 

In Laravel, i can bring the errors array in this way, but how can I bring them back from Livewire?

if ($validator->fails())
{
    return dd($validator->messages());    
}

Using $this->validate() will throw an exception when there are validation-errors. This exception can be caught in a try/catch, and if its not caught, Laravel will catch it with its global exception-handler (which will enable the @error directive in blade, or the $errors variable in your view.

You can intercept this by catching it yourself and handling the logic you want to apply. Its also recommended that you re-throw the exception after that, so that execution of the method stops, and that you get the default Laravel behavior in your view.

public function submit()
{
    try {
        $this->validate(); 
    } catch (\Illuminate\Validation\ValidationException $e) { 
        // Use $e->errors() to find the validationerrors
        // Add your custom logic here. 

        // Re-throw the exception once done
        throw $e;
    }

    Contact::create([
        'name' => $this->name,
        'email' => $this->email,
    ]);
}
