PHP Data Validator
Cake is the latest validation project. Cake is based on "Validatio" and at all Validatio is a nice script, but the main reason to change to Cake is that Cake is 10 times faster than Validation and this is a massive increase in performance., (*1)
Just use Composer, (*2)
composer require sweetcode/cake
It's really simple to use., (*3)
1 - First of all create a new instance that you can use to validate your fields, (*4)
$cake = new Cake;
2 - You need a array to validate. The array should follow the following pattern:, (*5)
key: <field-name>(|<field-name-alias>)
value: array(
key: <field-value>
value: <field-rule>(|<field-rule>|<field-rule>(arguments)...)
)
$fields = [
'username' => ['Yonas' => 'required|minlength(3)|maxlength(12)|alphanumeric'],
'password' => ['test' => 'required|match(repeatPassword)|minlength(4)'],
'passwordRepeat' => ['testit' => 'required'],
'email' => ['test@test.com' => 'required|email']
];
3 - Now we validate the given fields.
$errorHandler = $cake->validate($fields);
4 - The Cake#validate() method returns a CakeErrorHandler instance. You can use this instance to echo out the errors.
if($errorHandler->valid()) {
echo "No errors found.";
} else {
var_dump($errorHandler->getErrors());
}

# How can I add my own rules?
1. Method Name: `rule__<your-rule-name>` | Replace the `<your-rule-name>` with your rule name
2. Method Arguments: `rule__<your-rule-name>($field, $value, $arguments)` | Your rule method needs three arguments.
$field => the field name
$value => the given value from the field
$arguments => the given arguments that are passed into the method
2.1) The names of the arguments doesn't matter 3. The rule method must be "public" 4. Done! - Now you can use your rule to validate fields., (*6)
