我编写了自己的简单类，将多年来收集的一些正则表达式与PHP的sanatize和filter函数结合在一起。
<?class FormValidator{ public static $regexes = Array( 'date' => "^[0-9]{4}[-/][0-9]{1,2}[-/][0-9]{1,2}$", 'amount' => "^[-]?[0-9]+$", 'number' => "^[-]?[0-9,]+$", 'alfanum' => "^[0-9a-zA-Z ,.-_\s?!]+$", 'not_empty' => "[a-z0-9A-Z]+", 'words' => "^[A-Za-z]+[A-Za-z \s]*$", 'phone' => "^[0-9]{10,11}$", 'zippre' => "^[1-9][0-9]{3}[a-zA-Z]{2}$", 'plate' => "^([0-9a-zA-Z]{2}[-]){2}[0-9a-zA-Z]{2}$", 'price' => "^[0-9.,]*(([.,][-])|([.,][0-9]{2}))?$", '2digitopt' => "^d+(,d{2})?$", '2digitforce' => "^d+,dd$", 'anything' => "^[dD]{1,}$" ); private $validations, $sanatations, $mandatories, $errors, $corrects, $fields; public function __construct($validations=array(), $mandatories = array(), $sanatations = array()) { $this->validations = $validations; $this->sanatations = $sanatations; $this->mandatories = $mandatories; $this->errors = array(); $this->corrects = array(); } public function validate($items) { $this->fields = $items; $havefailures = false; foreach($items as $key=>$val) { if((strlen($val) == 0 || array_search($key, $this->validations) === false) && array_search($key, $this->mandatories) === false) { $this->corrects[] = $key; continue; } $result = self::validateItem($val, $this->validations[$key]); if($result === false) { $havefailures = true; $this->addError($key, $this->validations[$key]); } else { $this->corrects[] = $key; } } return(!$havefailures); } public function getscript() { if(!empty($this->errors)) { $errors = array(); foreach($this->errors as $key=>$val) { $errors[] = "'INPUT[name={$key}]'"; } $output = '$$('.implode(',', $errors).').addClass("unvalidated");'; $output .= "alert('there are errors in the form');"; // or your nice validation here } if(!empty($this->corrects)) { $corrects = array(); foreach($this->corrects as $key) { $corrects[] = "'INPUT[name={$key}]'"; } $output .= '$$('.implode(',', $corrects).').removeClass("unvalidated");';} $output = "<script type='text/javascript'>{$output} </script>"; return($output); } public function sanatize($items) { foreach($items as $key=>$val) { if(array_search($key, $this->sanatations) === false && !array_key_exists($key, $this->sanatations)) continue; $items[$key] = self::sanatizeItem($val, $this->validations[$key]); } return($items); } private function addError($field, $type='string') { $this->errors[$field] = $type; } public static function sanatizeItem($var, $type) { $flags = NULL; switch($type) { case 'url': $filter = FILTER_SANITIZE_URL; break; case 'int': $filter = FILTER_SANITIZE_NUMBER_INT; break; case 'float': $filter = FILTER_SANITIZE_NUMBER_FLOAT; $flags = FILTER_FLAG_ALLOW_FRACTION | FILTER_FLAG_ALLOW_THOUSAND; break; case 'email': $var = substr($var, 0, 254); $filter = FILTER_SANITIZE_EMAIL; break; case 'string': default: $filter = FILTER_SANITIZE_STRING; $flags = FILTER_FLAG_NO_ENCODE_QUOTES; break; } $output = filter_var($var, $filter, $flags); return($output); } public static function validateItem($var, $type) { if(array_key_exists($type, self::$regexes)) { $returnval = filter_var($var, FILTER_VALIDATE_REGEXP, array("options"=> array("regexp"=>'!'.self::$regexes[$type].'!i'))) !== false; return($returnval); } $filter = false; switch($type) { case 'email': $var = substr($var, 0, 254); $filter = FILTER_VALIDATE_EMAIL; break; case 'int': $filter = FILTER_VALIDATE_INT; break; case 'boolean': $filter = FILTER_VALIDATE_BOOLEAN; break; case 'ip': $filter = FILTER_VALIDATE_IP; break; case 'url': $filter = FILTER_VALIDATE_URL; break; } return ($filter === false) ? false : filter_var($var, $filter) !== false ? true : false; }}现在，这需要在此处看到的某些javascript的mootools，但是您可以轻松地将其更改为您喜欢的javascript框架。它所做的只是查找元素，并向其中添加“未验证的”
CSS类。
使用就像我一直想要的那样简单：
例：
$validations = array( 'name' => 'anything', 'email' => 'email', 'alias' => 'anything', 'pwd'=>'anything', 'gsm' => 'phone', 'birthdate' => 'date');$required = array('name', 'email', 'alias', 'pwd');$sanatize = array('alias');$validator = new FormValidator($validations, $required, $sanatize);if($validator->validate($_POST)){ $_POST = $validator->sanatize($_POST); // now do your saving, $_POST has been sanatized. die($validator->getscript()."<script type='text/javascript'>alert('saved changes');</script>");}else{ die($validator->getscript());}要仅验证一个元素：
$validated = new FormValidator()->validate('blah@bla.', 'email');要清理一个元素：
$sanatized = new FormValidator()->sanatize('<b>blah</b>', 'string');关于此类的最酷的事情是，您可以使用ajax或iframe目标发送表单并执行生成的脚本。无需刷新页面或将相同的表单数据重新发送回浏览器:)此外，如果脚本需要更改，则无需进行过度设计的框架分析，只需按需要进行更改即可：)
哦，是的，随时随地使用此功能。没有许可证
