Custor error message

Hi :-)

I am glad you like it.

And for sure, it is possible to define customizable error message. Let's see example, it is better than 1000 words ;-)

$URLs_field = new Form_Field_Input(name: 'URL',label: 'URL:');

$URLs_field->setErrorMessages([
    'not_unique_URL' => 'URL %URL% is not unique. It is already used by %URL_USEAGE%',
    'invalid_URL' => 'URL %URL% is not valid'
]);
$URLs_field->setValidator( function() use ($URLs_field) : bool {
    $URL = $URLs_field->getValue();

    if(!$URL) {
        $URLs_field->setError( Form_Field::ERROR_CODE_EMPTY );
        return false;
    }

    if( URL_Checker::URLUsed( $URL, $URL_usage ) ) {
        $URLs_field->setError('not_unique_URL', [
            'URL' => $URL,
            'URL_USEAGE' => $URL_usage
        ]);

        return false;
    }

    if(!filter_var('https://'.$URL, FILTER_VALIDATE_URL)) {
        $URLs_field->setError('invalid_URL', [
           'URL' => $URL
        ]);
        return false;
    }

    return true;
} );

As you can see, it is possible to define custom error messages with custom codes

$URLs_field->setErrorMessages([
    'not_unique_URL' => 'URL %URL% is not unique. It is already used by %URL_USEAGE%',
    'invalid_URL' => 'URL %URL% is not valid'
]);

and then set these errors and define values for the error message:

$URLs_field->setError('not_unique_URL', [
            'URL' => $URL,
            'URL_USEAGE' => $URL_usage
        ]);
