word-validator Validates words count, blacklist and whitelist.

  1. Requirements
  2. Installation
  3. Usage

EWordValidator validates that the attribute value has a specific words count and checks this value against whitelist and blacklist.

Requirements

Tested in Yii 1.1.10, but should work starting from Yii 1.1.7

Installation

Extract the archive and put the file under protected/extensions directory. (Or under protected/extensions/validators to keep things organized)

Usage

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

public function rules()
{
   return array(
       //other validators...
       array('attributeName', 'ext.EWordValidator'/*,add here needed rules*/),
   );
}
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:

array(/*...*/
    'messages' => array(
        'min' => 'Your {attribute} is now has {length} words. But should be 
             at least {min}'
    ),
),
Filter (since 1.1)

Added ability to filter data before validation.

  • filter - a valid php callback. Takes a model attribute as a first argument.
  • filterClient - a valid javascript callback.
Example

Check if a "body" attribute has from 2 to 5 words count, contains either the word "please" or "test" and does not contain a word "restricted" and "email.*" expression. Also the default message for "max" rule is overridden.

array('body', 'ext.EWordValidator',
         'min' => 2,
         'max' => 5,
         'whitelist' => array('please', 'test'), 
         'blacklist' => array('restricted', 'email.*'), 
         'messages'  => array(
            'max' => '{attribute} is too long (maximum is {max} words, 
                      but now it\'s {length})'
         ),
),

Also a client side validation is supported.
