Question

先关闭，先谢谢你。我正在用PHP编写注册页面并使用Jquery Validate来检查表单。当表单填写不正确时，它返回错误，但是当它被正确填写时，它只是刷新并且没有完成我在isset $ _POST函数中委派的操作。这是我正在处理的事情：

PHP如果表单不为空

    //Escape high risk symbols

    $pw= mysqli_real_escape_string($con, $_POST['pass']);
    $username= mysqli_real_escape_string($con, $_POST['pass']);
    $email = mysqli_real_escape_string($con, $_POST['email']);
    $sex = mysqli_real_escape_string($con, $_POST['sex']);
    $signedUp = date("Y-m-d H:i:s");
    $hash = password_hash($pw, PASSWORD_DEFAULT);

    echo 'Email: '.$email;
    echo 'Username: '.$username;
    echo 'Sex: '.$sex;
    echo 'Signed Up: '.$signedUp;
}
?>

这是表格

    <form method="post" class="form-signin" id="signup" name="signup">
                ...   
    </form>

这是我的验证javascript，似乎它没有发布

<script src="js/formValidate.js"></script>
<script>
     // When the document is ready
     $(document).ready(function () {
         //validation rules
         $("#signup").validate({
             onkeyup: false,
             onfocusout: false,
             errorElement: "div",
             errorPlacement: function(error, element) {
                 error.appendTo("div#errors");
         },
         rules: {
             email: {
                 required : true,
                 email: true
                 //equalTo: "#example3-field2"
             },
             username: {
                 required: true,
                 minlength: 5
             },
             pass: {
                 required : true,
                 minlength: 5
             },
             cPass: {
                 required : true,
                 equalTo : "#pass"
             },
             sex: {
                 required : true
             },
         },
         messages: {
             email: {
                 required: "You must enter an email address",
                 email: "Enter a valid email address"
                 //equalTo: "Field 1 must be equal to Field 2"
             }, 
             username: {
                 required: "You must choose a username",
                 minlength: "Username must be a minimum of 5 characters"
             }, 
             pass: {
                 required : "You are required to enter a password!",
                 minlength : "Password must be at least 5 characters!"                                          
             },
             cPass : {
                 required : "You are required confirm your password!",
                 equalTo : "Passwords do not match"
             },
             sex : {
                 required : "You are required to choose a sex"
             },
         }, 
        submitHandler: function(form) {
            form.submit();
        }
    });             
});
</script>

Answer 1

我认为问题是您正在尝试查看FORM是否存在（注册），您需要验证其中一个字段，例如：

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

由于您似乎正在尝试验证表单，并且该索引永远不会出现在$ _POST中。

Answer 2

你应该使用类似的东西来检查你的请求是否是POST。

if($_SERVER['REQUEST_METHOD'] === 'POST') {
   // do your stuff.
}

相关问题， Check whether a request is GET or POST

在isset $ _POST旁边使用表单验证时，页面刷新但不会提交
