How to customize $fail message (with html too) to an existing rule ?

For example, you are using ->unique(User::class, 'email'). The default error message will be: "The email has already been taken" since this is coming from the en/validation.php . How about if you need html for that like "This email already exists. <a href="url('forgot-password;)">Forgot Password?</a>" ?

try to override validate function like this

public function validate(): array
    {
        if (! count($this->getComponents())) {
            return [];
        }

        $rules = $this->getValidationRules();

        if (! count($rules)) {
            return [];
        }

        return $this->getLivewire()->validate($rules, ['email.unique' => 'This email already exists. <a href="url(\'forgot-password\')">Forgot Password?</a>'], $this->getValidationAttributes());
    }

public function validate(): array
    {
        if (! count($this->getComponents())) {
            return [];
        }

        $rules = $this->getValidationRules();

        if (! count($rules)) {
            return [];
        }

        return $this->getLivewire()->validate($rules, ['email.unique' => 'This email already exists. <a href="url(\'forgot-password\')">Forgot Password?</a>'], $this->getValidationAttributes());
    }

Declaration of App\Http\Livewire\Auth\RegisterPage::validate(): array must be compatible with Livewire\Component::validate($rules = null, $messages = [], $attributes = [])

@vahnmarty Is this a custom form? An idea would be to add the link conditionally, in a custom View below your form field:

Forms\Components\View::make('forgot-password')

Forms\Components\View::make('forgot-password')

@error('data.email')
    <a href=" ... ">Forgot Password?</a>
@enderror

@error('data.email')
    <a href=" ... ">Forgot Password?</a>
@enderror

I want it below in the email textbox. One thing that worked for me is by using Placeholder

Placeholder::make('existing_email')
                ->label('')
                ->dehydrated(false)
                ->visible(fn(Closure $get) => User::where('email', $get('email'))->exists())
                ->reactive()
                ->content(fn() => new HtmlString('<p class="-my-2 text-sm">This email already exists. <a href="forgot-password" class="text-link">Forgot Password?</a></p>')),

Placeholder::make('existing_email')
                ->label('')
                ->dehydrated(false)
                ->visible(fn(Closure $get) => User::where('email', $get('email'))->exists())
                ->reactive()
                ->content(fn() => new HtmlString('<p class="-my-2 text-sm">This email already exists. <a href="forgot-password" class="text-link">Forgot Password?</a></p>')),

But this one is using manual validation ->visible(fn(Closure $get) => User::where('email', $get('email'))->exists()) and not the ->unique() . ---- Ok I'll try this View

Ah nvm, the i think you are referring to the layout View https://filamentphp.com/docs/2.x/forms/layout#view

There is some awkward space in between.

Patrick Boivin•2y ago

Ah yes, that's because the View creates an empty row in the layout... You could try a negative margin-top. Maybe your Placeholder was a better idea after all ☝️
