``` Initial the Validator object by `$_POST` ``` $validator = Validator::factory($_POST); ``` The example of $\_POST like: ``` $_POST = array( 'username' => "", 'password' => "123456", 'confirm_password' => "125", 'first_name' => "123", 'telephone' => '123456789', 'email' => "abc@abc", 'emails' => "abc@abc.com,abc@abc.com,abc", 'url' => "http://127.0.0.1/()", 'ip' => '127.0.0.1a', 'title' => '123a', 'age' => 17, 'custom' => "2001-12", 'gender' => 'boy', 'zip_code' => 1002, ); ``` Then, add the **target keys/fields** and **checking rules** ``` $validator = Validator::factory($data); $validator->add('username', 'Pleas enter username')->rule('required'); $validator->add('username', 'The username must less than 4 char')->rule('min_length', 4); // empty so not show $validator->add('password', 'Password not match input value')->rule('match_value', $data['confirm_password']); $validator->add('first_name', 'The first name not match given pattern')->rule('match_pattern', '/^[A-Za-z]/'); $validator->add('password', 'Password not match given field')->rule('match_field', 'confirm_password'); $validator->add('confirm_password', 'Confirm password must more than 4 char')->rule('min_length', 4); $validator->add('telephone', 'The telephone number must less than 8 char')->rule('max_length', 8); $validator->add('telephone', 'The telephone number length must equals 8 char')->rule('exact_length', 8); $validator->add('email', 'Invalid email address')->rule('valid_email'); $validator->add('url', 'Invalid email address')->rule('valid_url'); $validator->add('ip', 'Invalid ip address')->rule('valid_ip'); $validator->add('title', 'The string is not alpha string')->rule('valid_string'); $validator->add('age', 'The age must less than 18 age')->rule('numeric_min', 18); $validator->add('age', 'The age must bigger than 16 age')->rule('numeric_max', 16); $validator->add('custom', 'The value is not much the custom format')->rule('custom', function($val) { return preg_match('/2001\-10/', $val) > 0; }); $validator->add('name', 'The name is equals to Tomcat')->rule('is_true', function($val) { return $val === "Tomcat"; }); $validator->add('name', 'The name is not equals to Cattom')->rule('is_false', function($val) { return $val === "Cattom"; }); $validator->add('gender', "The gender is supported")->rule('between', array('boy', 'girl')); $validator->add('zip_code', 'The zip code is not exists')->rule('key_exists', array( 1002 => "B", 1003 => "C", 1004 => "D", )); ``` But, you can make it chainable like ``` $validator->add('username', 'Pleas enter username')->rule('required') ->add('username', 'The username must less than 4 char')->rule('min_length', 4) ->add('password', 'Password not match input value')->rule('match_value', $data['confirm_password']) ->add('first_name', 'The first name not match given pattern')->rule('match_pattern', '/^[A-Za-z]/') ->add('password', 'Password not match given field')->rule('match_field', 'confirm_password') ->add('confirm_password', 'Confirm password must more than 4 char')->rule('min_length', 4) ->add('telephone', 'The telephone number must less than 8 char')->rule('max_length', 8) ->add('telephone', 'The telephone number length must equals 8 char')->rule('exact_length', 8) ->add('email', 'Invalid email address')->rule('valid_email') ->add('url', 'Invalid email address')->rule('valid_url') ->add('ip', 'Invalid ip address')->rule('valid_ip') ->add('title', 'The string is not alpha string')->rule('valid_string') ->add('age', 'The age must less than 18 age')->rule('numeric_min', 18) ->add('age', 'The age must bigger than 16 age')->rule('numeric_max', 16) ->add('custom', 'The value is not much the custom format')->rule('custom', function($val) { return preg_match('/2001\-10/', $val) > 0; })->rule('valid_string', array('utf8', 'alpha', 'lowercase')) ->add('name', 'The name is equals to Tomcat')->rule('is_true', function($val) { return $val === "Tomcat"; }) ->add('name', 'The name is not equals to Cattom')->rule('is_false', function($val) { return $val === "Cattom"; }) ->add('gender', "The gender is supported")->rule('between', array('boy', 'girl')); ->add('zip_code', 'The zip code is not exists')->rule('key_exists', array( 1002 => "B", 1003 => "C", 1004 => "D", )); ``` Finally, when you added rules completely, you can run the checking. ``` if ($validator->inValid() === true) { foreach($validator->errors() as $error) { echo "",$error,""; } } ``` The method `$validator->inValid()` or alias method `$validator->valid()` will return the status of validation (true is contain error), the `$validator->error()` will contain all error messages. if you just want to show first error message, you can use method: `$validator->firstError()` ``` if ($validator->inValid() === true) { echo $validator->firstError(); // pop first error } ``` All avaliable method: ``` required min_length, 100 match_value, "string" match_pattern, /regex/ match_field, "post_field" max_length, 100 exact_length, 8 (equals length) valid_email valid_url valid_ip valid_string numeric_min, 18 numeric_max, 16 custom, callback is_true, callback (callback result is true) is_false, callback (callback result is false) between, array('HK', 'TW') key_exists, array(1 => 'A',) ``` ### Health Score 23 — LowBetter than 27% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity16 Limited adoption so far Community6 Small or concentrated contributor base Maturity41 Maturing project, gaining track record Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
