Fat Free Framework Validator

An easy to use and strait to the point validation trait for Fat Free Framework

Installation

Using Composer

composer require geofmureithi/f3-validate

Manually

Copy the lib\validate.php file to the lib folder or any root of an auto included folder.

Remember it requires at least php 5.4 to use traits

Getting Started

class Profile
{
    use Validate; //<--- Trait

    public function getRules()
    {
        return [
            "email" => "reqired|email"
        ];
    }
    
    public function save()
    {
        //.....
    }
}

$data = $f3->get('POST')
$profile = new Profile();
$result = $profile->check($data);
if( $result != true) return $result; //errors
$profile->save();

Available Validators

• required Ensures the specified key value exists and is not empty
• email Checks for a valid email address
• max_length,n Checks key value length, makes sure it's not longer than the specified length. n = length parameter.
• min_length,n Checks key value length, makes sure it's not shorter than the specified length. n = length parameter.
• exact_length,n Ensures that the key value length precisely matches the specified length. n = length parameter.
• alpha Ensure only alpha characters are present in the key value (a-z, A-Z)
• alpha_numeric Ensure only alpha-numeric characters are present in the key value (a-z, A-Z, 0-9)
• numeric Ensure only numeric key values
• boolean Checks for PHP accepted boolean values, returns TRUE for "1", "true", "on" and "yes"
• url Check for valid URL or subdomain
• ipv4 Check for valid IPv4 address
• ipv6 Check for valid IPv6 address
• card Check for a valid credit card number (Uses the MOD10 Checksum Algorithm)
• phone Validate phone numbers that match the following examples: 555-555-5555 , 5555425555, 555 555 5555, 1(519) 555-4444, 1 (519) 555-4422, 1-555-555-5555
• regex You can pass a custom regex using the following format: 'regex,/your-regex/'

Adding custom validators and filters is made easy by using callback functions.

$message = "The value of {0} must include each of these items : {1}";
Validate::addValidator("contains", function ($value, $ruleConfigs) {
  $required = explode("&", substr($ruleConfigs[0], 1, -1));
  $diff = array_diff($required, explode(",", $value));
  return empty($diff);
 }, $message);
 
 //Or
Validate::addValidator("custom", "SampleClass::testCustom", "Custom Error");
