本文实例讲述了PHP验证类的封装与使用方法。分享给大家供大家参考,具体如下:
<?php /** * Created by PhpStorm. * User: jiqing * Date: 18-7-24 * Time: 下午4:36 * 常用验证 */ class Valid { static protected $error; static protected $error_tips = [ 'tel' => '手机号格式有误', 'email' => '邮箱格式有误', 'max_len' => '参数长度不能超过最大长度', 'min_len' => '参数长度不能小于最小长度', 'required' => '缺少参数' ]; // required|max_len,100|min_len,6 public function validate($field, $rules) { $rules = explode('|', $rules); foreach ($rules as $rule) { $method = null; $param = null; // Check if we have rule parameters if (strstr($rule, ',') !== false) { $rule = explode(',', $rule); $method = 'check_'.$rule[0]; $param = $rule[1]; $rule = $rule[0]; } else { $method = 'check_'.$rule; } $method_array = get_class_methods(new Valid()); if (!in_array($method,$method_array)) { self::$error[] = "Method not exist."; } if (!self::$method($field,$param)) { self::$error[] = self::$error_tips[$rule] ? self::$error_tips[$rule] : '参数格式有误'; } } if (count(self::$error) == 0) { return 0; } return self::$error[0]; // 返回第一个错误 } public static function check_required($field) { if (isset($field) && ($field === false || $field === 0 || $field === 0.0 || $field === '0' || !empty($field))) { return true; } else { return false; } } public static function check_tel($field) { if(preg_match("/^1[345678]{1}\d{9}$/",$field)){ return true; }else{ return false; } } public static function check_email($field) { if(preg_match("/^[a-zA-Z0-9_-]+@[a-zA-Z0-9_-]+(\.[a-zA-Z0-9_-]+)+$/",$field)){ return true; }else{ return false; } } public static function check_max_len($field,$param = null) { if (function_exists('mb_strlen')) { if (mb_strlen($field) <= (int) $param) { return true; } else { return false; } } else { if (strlen($field) <= (int) $param) { return true; } else { return false; } } } public static function check_min_len($field,$param = null) { if (function_exists('mb_strlen')) { if (mb_strlen($field) >= (int) $param) { return true; } else { return false; } } else { if (strlen($field) >= (int) $param) { return true; } else { return false; } } } public static function check_regex($field, $param = null) { $regex = $param; if (preg_match($regex, $field)) { return true; } else { return false; } } }
基本满足需求。
vendor('Func.Valid'); if ($res = Valid::validate('152','required|regex,/^1[345678]{1}\d{9}$/')) { $this->json->setErr(10001,$res); $this->json->Send(); }
封装很有意思,这个类唯一的亮点,就是可以复合验证。并且支持正则。而且里面的验证方法还可以单独使用。
vendor('Func.Valid'); if (!Valid::check_tel('152')) { $this->json->setErr(10001,'手机号有误'); $this->json->Send(); }
勇敢的封装,利国利民。
继续封装,支持数组传参。
<?php /** * Created by PhpStorm. * User: jiqing * Date: 18-7-24 * Time: 下午4:36 * 常用验证 */ class Valid { static protected $error; static protected $error_tips = [ 'tel' => '手机号格式有误', 'email' => '邮箱格式有误', 'max_len' => '参数长度不能超过最大长度', 'min_len' => '参数长度不能小于最小长度', 'required' => '缺少参数' ]; /** * @param $validators array array('email' => 'required|valid_email') * @param $input array post数据 * @return string */ public function is_valid($validators, $input) { foreach ($validators as $field => $rules) { if (!isset($input[$field]) || empty($input[$field])) { self::$error[] = "缺少参数"; } $rules = explode('|', $rules); foreach ($rules as $rule) { $method = null; $param = null; // Check if we have rule parameters if (strstr($rule, ',') !== false) { $rule = explode(',', $rule); $method = 'check_'.$rule[0]; $param = $rule[1]; $rule = $rule[0]; } else { $method = 'check_'.$rule; } $method_array = get_class_methods(new Valid()); if (!in_array($method,$method_array)) { self::$error[] = "Method not exist."; } if (!self::$method($input[$field],$param)) { self::$error[] = self::$error_tips[$rule] ? self::$error_tips[$rule] : '参数格式有误'; } } } if (count(self::$error) == 0) { return 0; } return self::$error[0]; // 返回第一个错误 } /** * @param $field string 验证字段 * @param $rules string 验证规则 required|max_len,100|min_len,6 * @return string */ public function validate($field, $rules) { $rules = explode('|', $rules); foreach ($rules as $rule) { $method = null; $param = null; // Check if we have rule parameters if (strstr($rule, ',') !== false) { $rule = explode(',', $rule); $method = 'check_'.$rule[0]; $param = $rule[1]; $rule = $rule[0]; } else { $method = 'check_'.$rule; } $method_array = get_class_methods(new Valid()); if (!in_array($method,$method_array)) { self::$error[] = "Method not exist."; } if (!self::$method($field,$param)) { self::$error[] = self::$error_tips[$rule] ? self::$error_tips[$rule] : '参数格式有误'; } } if (count(self::$error) == 0) { return 0; } return self::$error[0]; // 返回第一个错误 } public static function check_required($field) { if (isset($field) && ($field === false || $field === 0 || $field === 0.0 || $field === '0' || !empty($field))) { return true; } else { return false; } } /** * 简写 * @param $field * @return bool */ public static function check_r($field) { if (isset($field) && ($field === false || $field === 0 || $field === 0.0 || $field === '0' || !empty($field))) { return true; } else { return false; } } public static function check_tel($field) { if(preg_match("/^1[345678]{1}\d{9}$/",$field)){ return true; }else{ return false; } } public static function check_email($field) { if(preg_match("/^[a-zA-Z0-9_-]+@[a-zA-Z0-9_-]+(\.[a-zA-Z0-9_-]+)+$/",$field)){ return true; }else{ return false; } } public static function check_max_len($field,$param = null) { if (function_exists('mb_strlen')) { if (mb_strlen($field) <= (int) $param) { return true; } else { return false; } } else { if (strlen($field) <= (int) $param) { return true; } else { return false; } } } public static function check_min_len($field,$param = null) { if (function_exists('mb_strlen')) { if (mb_strlen($field) >= (int) $param) { return true; } else { return false; } } else { if (strlen($field) >= (int) $param) { return true; } else { return false; } } } public static function check_regex($field, $param = null) { $regex = $param; if (preg_match($regex, $field)) { return true; } else { return false; } } }
使用如下
vendor('Func.Valid'); $validators = [ 'tel' => 'required|tel', 'name' => 'required', 'email' => 'r|email', 'password' => 'r|min_len,6|max_len,12' ]; if ($err = Valid::is_valid($validators,$_POST)) { $this->json->setErr(10001,$err); $this->json->Send(); }
继续优化!支持错误提示中,添加参数。
<?php /** * Created by PhpStorm. * User: jiqing * Date: 18-7-24 * Time: 下午4:36 * 常用验证 */ class Valid { static protected $error; /** * @param $validators array array('email' => 'required|valid_email') * @param $input array post数据 * @return string */ public function is_valid($validators, $input) { foreach ($validators as $field => $rules) { if (!isset($input[$field]) || empty($input[$field])) { self::$error[] = "缺少参数"; } $rules = explode('|', $rules); foreach ($rules as $rule) { $method = null; $param = null; // Check if we have rule parameters if (strstr($rule, ',') !== false) { $rule = explode(',', $rule); $method = 'check_'.$rule[0]; $param = $rule[1]; $rule = $rule[0]; } else { $method = 'check_'.$rule; } $method_array = get_class_methods(new Valid()); if (!in_array($method,$method_array)) { self::$error[] = "Method not exist."; } if (!self::$method($input[$field],$param)) { self::$error[] = self::get_error_tips($rule,$param); } } } if (count(self::$error) == 0) { return 0; } return self::$error[0]; // 返回第一个错误 } /** * @param $field string 验证字段 * @param $rules string 验证规则 required|max_len,100|min_len,6 * @return string */ public function validate($field, $rules) { $rules = explode('|', $rules); foreach ($rules as $rule) { $method = null; $param = null; // Check if we have rule parameters if (strstr($rule, ',') !== false) { $rule = explode(',', $rule); $method = 'check_'.$rule[0]; $param = $rule[1]; $rule = $rule[0]; } else { $method = 'check_'.$rule; } $method_array = get_class_methods(new Valid()); if (!in_array($method,$method_array)) { self::$error[] = "Method not exist."; } if (!self::$method($field,$param)) { self::$error[] = self::get_error_tips($rule,$param); } } if (count(self::$error) == 0) { return 0; } return self::$error[0]; // 返回第一个错误 } /** * 灵活获取参数 * @param $rule * @param $param */ public static function get_error_tips($rule,$param) { $error_tips = [ 'tel' => '手机号格式有误', 'email' => '邮箱格式有误', 'max_len' => '参数长度不能超过最大长度'.$param, 'min_len' => '参数长度不能小于最小长度'.$param, 'required' => '缺少参数', 'r' => '缺少参数' ]; return $error_tips[$rule] ? $error_tips[$rule] : '参数格式有误'; } public static function check_required($field) { if (isset($field) && ($field === false || $field === 0 || $field === 0.0 || $field === '0' || !empty($field))) { return true; } else { return false; } } /** * 简写 * @param $field * @return bool */ public static function check_r($field) { if (isset($field) && ($field === false || $field === 0 || $field === 0.0 || $field === '0' || !empty($field))) { return true; } else { return false; } } public static function check_tel($field) { if(preg_match("/^1[345678]{1}\d{9}$/",$field)){ return true; }else{ return false; } } public static function check_email($field) { if(preg_match("/^[a-zA-Z0-9_-]+@[a-zA-Z0-9_-]+(\.[a-zA-Z0-9_-]+)+$/",$field)){ return true; }else{ return false; } } public static function check_max_len($field,$param = null) { if (function_exists('mb_strlen')) { if (mb_strlen($field) <= (int) $param) { return true; } else { return false; } } else { if (strlen($field) <= (int) $param) { return true; } else { return false; } } } public static function check_min_len($field,$param = null) { if (function_exists('mb_strlen')) { if (mb_strlen($field) >= (int) $param) { return true; } else { return false; } } else { if (strlen($field) >= (int) $param) { return true; } else { return false; } } } public static function check_regex($field, $param = null) { $regex = $param; if (preg_match($regex, $field)) { return true; } else { return false; } } }
