Basic Usage

LValidator requirs 3 arguments, the first is array you want to validate, the second is the rules and the third is the overriding messages.

If overriding messages is not provided, the default messages will be used.

validate method returns true if validation is successful and array of errors if validation fails.

$valid_ids = [1,3,4];


$rules = [
    'username' => [
        'required',
        'alphanumeric',
        'min' => 3,
        'max' => 10
    ],

    'email' => [
        'required',
        'email'
    ],

    'id' => [
        'required',
        'numeric',
        'in' => $valid_ids
    ]
];

$overrride_messages = [
    'id' =>  [ 
        'in' => ['ID Must have value betweeen ' . implode(', ', $valid_ids)]
    ],
    'username' => [
        'required' => 'Username is required',
        'string' => 'Username must be string',
        'min' => 'Username must be at least 3 characters',
        'max' => 'Username must be at most 10 characters',
    ],
    'email' => [
        'required' => 'Email is required',
    ],
    'password' => [
        'required' => 'Password is required',
        'min' => 'Password must be at least 6 characters',
        'max' => 'Password must be at most 10 characters',
    ],
];

$v = new LValidator($_GET + $_POST, $rules, $overrride_messages);
$results = $v->validate();

var_dump($results);

Rules

Rules are array. Each rule is an array with key as the field name and value as the rule. The rule can be a string or a key value pair.

'username' => [
        'required',
        'alphanumeric',
        'min' => 3,
        'max' => 10
]

Overriding Messages

An overriding message is an array of messages. The key is the rule name and the value is the message.When a rule fails, the message will be used.

Available validations in package

• required($key)
• min($key, $value)
• max($key, $value)
• email($key)
• url($key)
• integer($key)
• float($key)
• boolean($key)
• alpha($key)
• alphanumeric($key)
• numeric($key)
• regex($key, $value)
• equal($key, $value)
• different($key, $value)
• contains($key, $value)
• starts_with($key, $value)
• ends_with($key, $value)
• length($key, $value)
• min_length($key, $value)
• max_length($key, $value)
• in($key, $value)
• not_in($key, $value)
• ip($key)
• mac_address($key)
• date_format($key, $value)
• boolean_string($key)
• is_valid_person_name($key)
• is_valid_person_name_with_space($key)
• date_between($key, $value)

Extending

You can add your own rules by adding rule handler. A rule handler is a funcion with two arguments, the first is the key and the second is the value. The function should return true if the value is valid and false if the value is invalid. The second argument is the optional.

public function islessthan10($key) {
    return intval($key) < 10;
}

public function islessthanVal($key, $val) { return intval($key) < intval($val); }
