用的是thinkphp5 + layui
代码：
public function add() { if($this->request->isAjax()) { $request = new Request(); $params = $this->request->param(); $title = $params['title']; $identity = $params['identity']; if(empty($identity)) { $this->error('请输入您的身份证号或护照号！'); } if( strlen($identity ) != 18 ) { $this->error('您输入的身份证号码有误！'); } $crad_id_base = substr($identity , 0, 17); $crad_id_verify = substr($identity , -1); // 加权因子 $factor = array(7, 9, 10, 5, 8, 4, 2, 1, 6, 3); // 校验码对应值 $verify_number_list = array('1', '0', 'X', '9', '8', '7', '6', '5', '4', '3', '2'); $checksum = 0; for( $i = 0; $i < strlen($crad_id_base); $i++ ) { $checksum += substr($crad_id_base, $i, 1) * $factor[$i % 10]; } $mod = $checksum % 11; if( $crad_id_verify == $verify_number_list[$mod] ) { $result = Db::name('volunteers')->where(['identity'=>$identity])->find(); if($result) { $this->error('该志愿者身份证号已存在，请勿重复添加！'); }else { $data = [ 'title' => isset($params['title']) ? $params['title'] : '', 'volun_no' => isset($params['volun_no']) ? $params['volun_no'] : '', 'userid' => isset($params['userid']) ? $params['userid'] : 0, 'createtime' => time(), 'updatetime' => time(), 'identity' => $params['identity'], 'identity_type' => isset($params['identity_type']) ? $params['identity_type'] : 1, ]; if($result = Db::name('volunteers')->insert($data)) { return $this->success('志愿者添加成功！'); }else{ return $this->error('志愿者添加失败！'); } return; } return; } } return $this->fetch(); }
