Laravel provides default error messages that are sufficient enough for most validation scenarios. In addition to that default one, you can add a custom validation error messages that you can define within the "resources/lang/[language]/validation.php" file.
resources/lang/[language]/validation.php
The validation errors can be defined in a key-value pair manner but you have to provide the appropriate structure in order for it to work.
Below is an example of how you can define the error validation message.
<?php # resources/lang/en/validation.php
return [
'custom' => [
'email' => [
'required' => 'We need to know your email address!',
'max' => 'Your email address is too long!'
],
],
],
