Question

我希望在插入mongodb之前验证输入字段有一些帮助。我在html5中创建一个注册表单，并使用php将值从from插入mongodb。我想验证字段的身份编号，南非身份数字长度为13位，我想将其分解以从身份编号中获取性别。我创建了一个javascript文件，用于验证字段的长度，但在javascript文件测试输入长度后仍然继续。我html5表单下面是它的css和链接的javascript文件。以下是注册表格registration form below register.php

<html>

在数据库中插入值的php脚本如下所示 process_register.php

 <?php

    if(isset($_POST['btnReg']))
    {
           $connection = new Mongo();
           $database = $connection->selectDB('licenseDiskDB');
           $collection = $database->selectCollection('tblusers');

           /*$userQuery = array('reg_username' =>$_POST['reg_username'],
                                'reg_idNumber' =>$_POST['reg_idNumber']);

           $cursor = $collection->findOne($userQuery);
           if($cursor['reg_username']!=$_POST['reg_username'])
           {*/
           $userQuery = array('reg_username' =>$_POST['reg_username']);

           $cursor = $collection->findOne($userQuery);
            $userQueryID = array('reg_idNumber' =>$_POST['reg_idNumber']);

           $IDUser = $collection->findOne($userQueryID);

               if(($cursor)||($IDUser))
               {
                   echo 'Already Registered!';
               }else
               {
                try
                {
                $newUser = array();
                $newUser['reg_username']=$_POST['reg_username'];
                $newUser['reg_password']=$_POST['reg_password'];
                $newUser['reg_name']=$_POST['reg_name'];
                $newUser['reg_surname']=$_POST['reg_surname'];
                $newUser['reg_idNumber']=$_POST['reg_idNumber'];
                $newUser['reg_gender']=$_POST['reg_gender'];
                $newUser['reg_race']=$_POST['reg_race'];
                $newUser['reg_nationality']=$_POST['reg_nationality'];
                $newUser['reg_address']=$_POST['reg_address'];

                $collection->insert($newUser);
                header("Location:http://localhost:8080/phpproject2/reg_success.php");

                } catch (MongoCursorException $ex)
                {
                     die('Insert Failed'.$ex->getMessage());
                }
               }

          /* }else
           {
               echo 'Insert Not Comleted';
           }*/

    }

?>

测试输入长度为13位的javascript低于

function validateID()
{
    var idNumber = document.getElementById('reg_idNumber');

    if((isNaN(idNumber))===true)
    {
        if(idNumber.toString().length===13)
        {
              alert('Soputh African ID');
        }else
        {
              alert('Incorrect Identity Number length');
              window.location="http://localhost:8080/PhpProject/register.php";
        }
    }else
    {
        alert('Identity Number should not contain characters');

        return true;
    }
}
