远程时jQuery验证插件停止

Question

这表明我的一个项目有一个小问题。

我在这个表单上使用 jquery 验证插件：

                  <input type="text" name = "lname" placeholder="Last Name" id="lname" required/>
                  <label for="lname" generated="true" class="error"></label>

                  <input type="text" name = "email" placeholder="E-mail" id="email" class="email" required/>
                  <label for="email" generated="true" class="error"></label>

                  <input type="text" name = "username" placeholder="Username" id="username" required/>
                  <label for="username" generated="true" class="error"></label>

                  <input type="password" name = "password" placeholder="Password" id="password" required/>
                  <label for="password" generated="true" class="error"></label>

                  <input type="password" name = "cpassword" placeholder="Confirm Password" id="confirm_password" required/>
                  <label for="cpassword" generated="true" class="error"></label>

                  <input class="button" type="submit" name="regbutton" id="regbutton" value="Register" />
              </form>

以下是规则：

$(document).ready(function () {

$('#registration').validate({

  rules: {
          fname:{
              minlength: 3,
          },
          lname: {
              minlength: 3,
          },
          email: {
              email: true,
              remote: { url:"../php/checkemail.php", async:false >}
          },
          username: {
              minlength: 4,
              maxlength: 16,
              remote: { url:"../php/checkusername.php", async:false }
          },
          password: {
              minlength: 8,
              maxlength: 16,
          },
          cpassword: {
              equalTo: "#password",
          },
  },
      messages: {
          fname: {
              minlength: "Your name must be at least 3 characters long.",
          },
          lname: {
              minlength: "Your name must be at least 3 characters long.",
          },
          email: {
              email: "Please enter a valid e-mail address.",
              remote: "This email is already registered.",
          },
          username: {
              minlength: "Your username must be at least 4 characters long but less than 16",
              maxlength: "Your username must be at least 4 characters long but less than 16",
              remote: "This username is already registered.",
          },
          password: {
              minlength: "Your password must be at least 8 characters long but less than 16",
              maxlength: "Your password must be at least 8 characters long but less than 16",
          },
          cpassword: {
              equalTo: "The passwords do not match.",
          },
      },

  submitHandler: function(form) { 
      $('#registration').submit();
      return false;
  },

}); });

还有 checkemail.php（checkusername.php 是一样的，但显然是用用户名而不是电子邮件）：

包括（'dbcon.php'）； if (isset($_POST['email']))

{
    $email = mysql_real_escape_string($_POST['email']);

    if (!empty($email)) 

{
        $email_query = mysql_query("SELECT *
                                       FROM users
                                       WHERE email = '$email'");
         if($email_query)

         {
           echo "true";
           exit;
         }
        else
        {
          echo "false";
          exit;
        }
} 

}

我已经尝试了我找到的所有组合。简单的遥控器：“url”，具有类型和数据的那个：{function....}等。没有任何接缝可以工作......检查PHP文件也是如此，每当我将远程线放在我的验证中时当我点击提交时，代码表单停止工作。如果我删除远程线路一切正常。有谁知道可能是什么问题？我真的没有想法，也无处可寻。

Answer 1

所以，

我将我的 php 文件更改为这个，因为我认为这是我的整个验证停止的地方：

if(isset($_POST['email']))

{

$email = mysqli_real_escape_string(strtolower($_POST['email']));

$check= mysqli_query("SELECT * FROM users WHERE LOWER email = '$email'");

if(mysqli_stmt_num_rows($check))

{

  echo "false";

}其他{

  echo "true";

}

}

但仍然没有...我没有收到任何消息，我的表单没有提交，除非我删除“remote：”url“”部分......然后一切都很好......

Answer 2

我让那部分工作，问题接缝是相对 url，它找不到 php 文件，所以我现在使用 ./ 而不是 ../ 并且它一直工作到那里，但在控制台中它给了我 200 ok 并且无论电子邮件和用户是否可用，它都会向我发送“真实”，并且它没有在表单中给我任何消息......有没有人知道如何解决这个问题?

另外，如果我输入 data: { x: function....} 并键入它会跳过整个验证，让我提交一个空表单。
