F3 :: Fat Free Framework Forms Validator

A Validation plugin for Fat Free Framework (Forked by GUMP). GUMP is a standalone PHP data validation and filtering class.

Installation

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

Getting Started

$data = $f3->get('POST')
$valid = Validate::is_valid($data, array(
	'username' => 'required|alpha_numeric',
	'password' => 'required|max_len,100|min_len,6'
));

if($valid === true) {
	// OK, let's use the posted values
} else {
	print_r($valid);
}

Available Validators

  • required Ensures the specified key value exists and is not empty
  • valid_email Checks for a valid email address
  • max_len,n Checks key value length, makes sure it's not longer than the specified length. n = length parameter.
  • min_len,n Checks key value length, makes sure it's not shorter than the specified length. n = length parameter.
  • exact_len,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)
  • alpha_dash Ensure only alpha-numeric characters + dashes and underscores are present in the key value (a-z, A-Z, 0-9, _-)
  • alpha_space Ensure only alpha-numeric characters + spaces are present in the key value (a-z, A-Z, 0-9, \s)
  • numeric Ensure only numeric key values
  • integer Ensure only integer key values
  • boolean Checks for PHP accepted boolean values, returns TRUE for "1", "true", "on" and "yes"
  • float Checks for float values
  • exists_url Check to see if the URL exists and is accessible
  • valid_url Check for valid URL or subdomain
  • valid_ip Check for valid generic IP address
  • valid_ipv4 Check for valid IPv4 address
  • valid_ipv6 Check for valid IPv6 address
  • valid_cc Check for a valid credit card number. Uses the MOD10 Checksum Algorithm
  • valid_name Check for a valid format human name
  • contains,n Verify that a value is contained within the pre-defined value set
  • containsList,n Verify that a value is contained within the pre-defined value set. The list of valid values must be provided in semicolon-separated list format (like so: value1;value2;value3;..;valuen). If a validation error occurs, the list of valid values is not revelead (this means, the error message will just tell the input is invalid, without displaying the valid set to the screen/user.
  • doesNotcontainList,n Verify that a value is not contained within the pre-defined value set. Semicolon (;) separated, list not outputted. See the rule above for more info.
  • street_address Checks that the provided string is a likely street address. 1 number, 1 or more space, 1 or more letters
  • valid_iban Check for a valid IBAN
  • min_numeric Determine if the provided numeric value is higher or equal to a specific value
  • max_numeric Determine if the provided numeric value is lower or equal to a specific value
  • date Determine if the provided input is a valid date (ISO 8601)
  • starts Ensures the value starts with a certain character / set of character
  • valid_phone_number 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/'
  • valid_json_string validate string to check if it's a valid json format
  • equals_fields Check if two fields are equals

Available Filters

Filters can be any PHP function that returns a string. You can create your own function or use an existing PHP function to use as the filter.

  • sanitize_string Remove script tags and encode HTML entities;
  • basic_tags Remove all layout orientated HTML tags from text. Leaving only basic tags
  • urlencode Encode url entities
  • htmlencode Encode HTML entities
  • sanitize_email Remove illegal characters from email addresses
  • sanitize_numbers Remove any non-numeric characters
  • whole_number Ensure that the provided numeric value is represented as a whole number
  • noise_words Remove noise words from string
  • trim Remove spaces from the beginning and end of strings
  • rmpunctuation Remove all known punctuation characters from a string
  • base64_encode Base64 encode the input
  • base64_decode Base64 decode the input
  • sha1 Encrypt the input with the secure sha1 algorithm
  • md5 MD5 encode the input
  • json_encode Create a json representation of the input
  • json_decode Decode a json string

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

/* 
   Create a custom validation rule named "is_code". Imagine we want the user to create a 6 letter code with 3 letters and 3 numbers eg: FAT300
   The callback receives 3 arguments:
   The field to validate, the values being validated, and any parameters used in the validation rule.
   It should return a boolean value indicating whether the value is valid.
*/
Validate::add_validator("is_code", function($field, $input, $param = NULL) {
    return preg_match("^[A-Z]{3}\d{3}$", $input[$field]);
});

/* 
   Create a custom filter named "upper".
   The callback function receives two arguments:
   The value to filter, and any parameters used in the filter rule. It should returned the filtered value.
*/
Validate::add_filter("upper", function($value, $params = NULL) {
    return strtoupper($value);
});
// This code must be included before activating the is_valid or run functions

Adding using with Cortex (by Ikkez):

class Category extends \DB\Cortex {
    protected $table ="categories";
    protected $fieldConf = [
        'code' => array(
            'type' => \DB\SQL\Schema::DT_VARCHAR128,
            'validate'=> 'required|max_len,3', //Validations
            'filter'=> 'trim|sanitize_string', //Filters
        ),
        'title' => array(
            'type' => \DB\SQL\Schema::DT_VARCHAR128,
            'validate'=> 'required|alpha_numeric', //Validations
            'filter'=> 'trim|sanitize_string', //Filters
        ),
		'slug' => array(
            'type' => \DB\SQL\Schema::DT_VARCHAR128,
        ),
        'description' => array(
            'type' => 'TEXT'
        ),
        'icon' => array(
            'type' => 'TEXT'
        ),
	]
}

/* Now in your controller or something */
    function add($f3) {

        if($f3->exists('POST')) {
            $this->model = new Category()
            $validator= \Validate::instance();
            $validator->add_cortex($this->model);
            $data= $f3->get('POST');
            if($validator->run($data)){
                $this->model->reset();
                $this->model->copyfrom('POST');
                $this->model->save();
                \Flash::instance()->addMessage('New Record Successfully added to Database','success');
                $f3->reroute('/admin/' .$this->prural);
            }
            foreach ($validator->get_errors_array() as $field=>$error) {
                #Handle Your errors
                //\Flash::instance()->addMessage($error,'warning');  # Uncomment if you are using Flash
            }

        }
        $f3->set('page.inner','/add.html');
        $f3->set('page.title','Add New'));

    }
