Greetings,

Trying out Aura.Filter for the first time instead of competing array validation libraries.

Is it possible to validate an array which has sub-arrays?  For example:

$subject = array(
    'username' => 'shskfhsdjh',
    'subArray' => array(
        1,2,3
    ),
    'subArray2' => array(
        'a1' => 'a',
        'a2' => 'b',
    )
);


Validating 'username' is easy, but how to validate the sub-arrays 'subArray' and 'subArray2'?:

# validate username
$filter->validate('username')->is('alnum');
$filter->validate('username')->is('strlenMin', 6);


If it's possible, I'd appreciate some pointers.

Thanks
Henry

I think you can use one of the below ones

1 . Callback https://github.com/auraphp/Aura.Filter/blob/2.x/docs/validate.md#callback and write custom logic if you prefer


There is inKeys : https://github.com/auraphp/Aura.Filter/blob/2.x/docs/validate.md#inkeys  ( But this probably is not what you are looking for in the case of subArray2 , but may be a combination of inValues and inKeys may help ? )

Thanks Hari - I also managed to figure this out using 'array' and a callback:

Valitron\Validator::addRule('arrayMin',
    function($field, $value, array $params, array $fields) {
    if (count($value) < $params[0]) {
        return false;
    }
    return true;
}, 'array size too small');

Valitron\Validator::addRule('inArray',
    function($field, $value, array $params, array $fields) {
    print "DEBUG: value:--> ".print_r($value,true)."<-- in params:[" . print_r($params,true)."]\n";
    if (in_array($value, $params)) {
        return true;
    }
    return false;
}, 'value not in array');

$rules = [
    'agentConf.*.groups' => ['required', 'array', ['arrayMin', 2]]
];


However, the following has me a bit stumped:

Given the following JSON structure:

$data = <<<ENDDATA
    {
        "agentConf": [{
            "first_name": "aaaa",
            "last_name": "bbbbb",
            "groups": [
                "sales",
                "Other"
            ],
            "groupPerms": [
                {
                "Other": [
                        "111",
                        "222",
                        "333"
                        ]
                },
                {
                "stats": [ "111" ]
                },
                {
                "sales": [ "111" ]
                }
            ]
        }]
    }
ENDDATA;

$rules = [
    'agentConf' => ['required', 'array', ['arrayMin', 1]],
        'agentConf.*.first_name' => ['required', ['regex', '/.*/']],
        'agentConf.*.last_name' => ['required', ['regex', '/.*/']],
        'agentConf.*.groups' => ['required', 'array', ['arrayMin', 2]],
            'agentConf.*.groups.*' => ['required', ['regex', '/.*/']],
        'agentConf.*.groupPerms' => ['required', 'array', ['arrayMin', 3]],
            'agentConf.*.groupPerms.*' => ['required', ['inArray', ['Other', 'stats', 'sales']]]
];
$data = json_decode($data, true);

$validator = new Valitron\Validator($data);
$validator->mapFieldsRules($rules);

if ($validator->validate()) {
    echo "OK\n";
} else {
    print_r($validator->errors());
    print "ERROR\n";
}

Validating 99% of the structure is relatively simple, however I'm not sure how to validate the groupPerms array to check whether it contains the keys "Other", "stats" and "sales"  --  ie the last rule:

'agentConf.*.groupPerms.*' => ['required', ['inArray', ['Other', 'stats', 'sales']]]

I tried inKeys, but it fails since it has not been registered with ::addRule().  I was under the impression it's a built-in Rule...

Thanks for any assistance.

Regards
H

I have not used Valitron nor this group supports discussion of a different library unless you are looking to use the two via some sort of bindings.

You may want to get support for Valitron on the means they provide.

Hope that helps and clear things.

Thank you.

eek!  My apologies - not sure what the hell happened.  Looks like I ended up using the wrong tab and assumed I was still on Aura/Filter!

Let me sort my sh*t out

Sorry once again
