October: Question: Does October have any built-in function to validate multiple languages

[ayumi-cloud]

Was thinking and wondering if October has any built in methods to validate multiple languages. Take the following example:

Backend Contact form (YAML)

fname:
    label: acme.example::lang.contactForm.firstName
    type: text
    span: left
lname:
    label: acme.example::lang.contactForm.lastName
    type: text
    span: right

Validation models (Laravel)

public $rules = [
    'fname' => [ 'nullable', 'regex:/(^[a-zA-Z\s\']+$)+/', 'max:100' ],
    'lname' => [ 'nullable', 'regex:/(^[a-zA-Z\s\']+$)+/', 'max:100' ],
];

In the above example let's say we want to validation an english first and last name.

It also links to the lang file: lang/en/lang.php

Now let's say I want to create a chinese lang file as well, e.g. lang/cn/lang.php

I don't want to Validate the contact form using a Latin character set, instead now I want to validate it using a Chinese character set.

If Statement (PHP)

// English
if ($lang === 'en') {
    public $rules = [
        'fname' => [ 'nullable', 'regex:/(^[a-zA-Z\s\']+$)+/u', 'max:100' ],
        'lname' => [ 'nullable', 'regex:/(^[a-zA-Z\s\']+$)+/u', 'max:100' ],
    ];

// Chinese
} elseif ($lang === 'cn') {
    public $rules = [
        'fname' => [ 'nullable', 'regex:/(^[\p{Han}+\s]+$)+/u', 'max:100' ],
        'lname' => [ 'nullable', 'regex:/(^[\p{Han}+\s]+$)+/u', 'max:100' ],
    ];
}

Above: Using a boring if statement to load each validation for each language. BUT not sure what October API, I could use to know and confirm the loaded lang file to use for the $lang string.

A Magic October Solution

I was wondering if there was a magic October CMS solution?

Maybe something like this (that directly connects to the Translate files):

public $rules = [
    'fname' => [ 'nullable', 'regex:/(^[a-zA-Z\s\']+$)+/u', 'max:100', 'lang:en' ],
    'fname' => [ 'nullable', 'regex:/(^[\p{Han}+\s\']+$)+/u', 'max:100', 'lang:cn' ],
    'lname' => [ 'nullable', 'regex:/(^[a-zA-Z\s\']+$)+/u', 'max:100', 'lang:en' ],
    'lname' => [ 'nullable', 'regex:/(^[\p{Han}+\s\']+$)+/u', 'max:100', 'lang:cn' ],
];

Or is there any special October API I could use to get the current backend loaded lang file - to connect up to the validation code?

Just wondering what would be an official solution and what could be an enhancement solution.

Thanks.

I believe you're looking for App::locale() which will return the currently active locale for the application.
