This is a simple and convenient PHP validator. It can be used to validate form input, API requests, and any other data that needs to be validated before being processed.

• PHP 8.1

composer require rnr1721/le7-validator

composer test

First you need to create an instance of the validator:

use Core\Utils\ValidatorFactory;

$validatorFactory = new ValidatorFactory();
$validator = $validatorFactory->getValidator();

Then you need to define validation rules for each field:

Method setFullRule can take three arguments:

• Field - Field (key) for validate.
• Value - Data to validate
• Rules - Validation rules
• Label - Human-like name of field. It uses for get errors

$validator->setFullRule('login', 'john', 'required|minlength:3|maxlength:5', 'Login');
$validator->setFullRule('email', '[email protected]', 'required|email', 'User email');
$validator->setFullRule('age', 35, 'min:22|max:55', 'User age');

And finally, you can check:

if ($validator->validate()) {
    // Validation success
} else {
    // Validation not success
    $errors = $validator->getMessages();
}

Rules - is string of "|" - separated rules. For example:

minlength:3|maxlength:10|numeric

• required: The field must be filled
• min:{n}: Field value must be at least {n}
• max:{n}: Field value must be no more than {n}
• minlength:{n}: The length of the string field value must be at least {n}
• maxlength:{n}: The length of the string field value must be no more than {n}
• email: The field value must be a valid email address
• notempty: The field value must not be empty or contain only spaces
• numeric: Validates that only numeric data
• email_dns: validates the format of an email address and checks if the domain part of the email address has a valid DNS record
• url: Validate URL
• url_active: If URL address is valid and exists
• date: Validates that value is date
• date_format:{n}: Validates date format: Example: date_format:Y-m-d
• date_before:{n}: Validate date before some date. Example: date_before:2022-05-15
• date_after:{n}: Validate date after some date. Example: date_after:2022-05-15
