Custom message for 'requiredIf' validation in Laravel

  • 772

I'm using custom messages in a validation with Laravel, most of them work for me but specifically the ones that are requiredIf don't work for me.

I've seen them used like this:

protected $mensajes = [
    'salas.required_if' => 'mensaje personalizado',
    'dormitorios.required_if' => 'mensaje personalizado'
]

but that doesn't work for me. I clarify that if it takes the data as mandatory when the condition is met, but it does not send the message that I defined, it sends one that I understand is predefined:

"The rooms field is mandatory"

"The bedrooms field is mandatory"

My condition is something like this:

$arreglo['salas'][] = Rule::requiredIf(function() use($request)
                          {
                               return $request->filled('dormitorios') ? false : true;
                          })

$arreglo['dormitorios'][] = Rule::requiredIf(function() use($request)
                          {
                               return $request->filled('salas') ? false : true;
                          })

To give a little more context as to what I want to do, I am receiving two arrangements in a request (living rooms, bedrooms), but I want at least one or both of them to always come, but if both are absent it would be wrong, and thus the validation of the requiredIf .

    The solution I got was to put the message for required , like this:

    protected $mensajes = [
    'salas.required' => 'mensaje personalizado',
    'dormitorios.required' => 'mensaje personalizado'
]

    I kept the validation the same:

    $arreglo['salas'][] = Rule::requiredIf(function() use($request)
                          {
                               return $request->filled('dormitorios') ? false : true;
                          })

$arreglo['dormitorios'][] = Rule::requiredIf(function() use($request)
                                {
                                     return $request->filled('salas') ? false : true;
                                })

    That way it started to work fine, the validation is still fulfilled for 'rooms' and 'bedrooms' but this time the message is the one I defined. To me this behavior makes sense since the required and requiredIf validations don't make sense for them to be together since required would take precedence over requiredIf . The only thing I find strange is that Laravel by default already has messages for required_if in the validation.php files located in the resources/lang directory , but that message never appears, instead the message for required from the same file always appears.

    The message "The field :attribute is required" that I mentioned in the statement of the problem, is found in the file resources/lang/en/validation.php .
