README

WordValidator validates that the attribute value has a specific words count and checks this value against whitelist and blacklist. It is a port of https://github.com/antonCPU/word-validator from Anton Yakushin from Yii 1 to Yii 2.

Requirements

Tested in Yii 2.0.9.

Installation

composer require thyseus/yii2-word-validator

Usage

Add the following code to your model class rules() method

use thyseus\validators\WordValidator;

public function rules()
{
   return [
       //other validators...
       array('attributeName', WordValidator::className(), /*add custom rules here*/),
   );
}

For example:

use thyseus\validators\WordValidator;

public function rules() {
  return [
    [['message'], WordValidator::className(),
    'min' => 2,
    'max' => 5,
    'whitelist' => array('please', 'test'),
    'blacklist' => array('restricted', 'email.*'), //could be a regular expression
    'messages'  => array(
        'max' => '{attribute} is too long (maximum is {max} words, but now it\'s {length})'
        ),
    ];
  ];

Validation rules

• max - the attribute should contain less (or equal) words count;
• min - minimum words count;
• exact - expected only this words count;
• blacklist - array of words that should not be in the attribute.

            There also could be a regular expression;
  

• whitelist - at least one of these words/expressions must be in the attribute.

Messages

Any default error message could be overridden using messages parameter. All messages support {attribute} and {length} placeholders. Each validation method adds it's value to a correspond (the same as a name) placeholder. For min rule a message could be specified as:

[/*...*/
    'messages' => array(
        'min' => 'Your {attribute} is now has {length} words. But should be
             at least {min}'
    ),
],

Client side validation is supported.
