Validation & Filter

Build elegant validation on top of (Wixel/GUMP), one of the most popular php validation.

Validation

$val = new Validator($_POST);

$val->field('name')->required()->validName();
// or
$val->name->required()->validName();

$val->if_valid(function() {
    // continue
})->else(function($err) {
    // array of error messages
    var_dump($err);
});

GUMP support

$is_valid = GUMP::is_valid(array_merge($_POST, $_FILES), [
    'username' => vr()->required()->alpha_numeric(),
    'password' => vr()->required()->between_len(6, 100),
    'avatar'   => vr()->required_file()->extension('png', 'jpg')
]);

if ($is_valid === true) {
    // continue
} else {
    // array of error messages
    var_dump($is_valid);
}

Filter

Filter field input

$val = new Validator($_POST);

$val->filter('name')->trim()->lowwer_case();

// run filter
$filter = $val->filter_out();

validation and filter

$val = new Validator($_POST);

$val->field('name')->required()->valid_name();
$val->filter('name')->trim()->lowwer_case();

// run validation and filter
$filter = $val->failedOrFilter());

Why use Validator

Why use validator over GUMP validator.

• Avoid typo when building validator rule. When using validator may accidentally type wrong validate rule (typo). It makes runtime error.
• Autocomplete out of the box. Auto complete validator rule and maintainable rule.
