Question

每当用户点击注册或注册时，我都试图更改表单中的属性。因此表单会相应更改，但是一旦用户单击注册，他们就无法再单击登录。

 <?php
 session_start();



    if(isset($_POST['submit'])) {
        include_once("php/config/database.php"); 
        $Email = strip_tags($_POST['Email']);
        $dbPassword = strip_tags($_POST['Password']);

        $Email = stripslashes($Email);
        $dbPassword = stripslashes($dbPassword);

        $Email = mysqli_real_escape_string($conn, $Email);
        $dbPassword = mysqli_real_escape_string($conn, $dbPassword);



        $sql = ("SELECT * FROM 'Users' WHERE Email='$Email' AND Password='$dbPassword' LIMIT 1");
        $query = mysqli_query($conn, $sql);
        $row = mysqli_fetch_array($query);
        $UserID = $row['UserID'];
        $dbpass = $row['Password'];

        if($dbPassword == $dbpass) {
            $_SESSION['Email'] = $Email;
            $_SESSION['UserID'] = $UserID;
            header("Location: account.php");
        } 
        else 
        {
            echo "You didn't enter the correct details!";
        }

    } 


?>

function register(){
var cont = 0;   

     cont++;

        if(cont==1){
            $('.box').animate({height:'600px'}, 550);
            $('.show').css('display','block');

            $('#textchange').text('Login');
            $('#search-theme-form').removeAttr("action").attr("action", "signup_destination.php");



        }

            $('#logintoregister').text('Login');
            $('#buttonlogintoregister').text('Login');
            $('#plogintoregister').text("Non sei iscritto?");
            $('#textchange').text('Register');
            $('#search-theme-form').removeAttr("action").attr("action", "index.php");


            cont = 0;


        }
}

Answer 1

每次运行函数时都会继续重置cont var，

var cont = 0;

因此，您将始终输入if的第一部分。

从函数中取出var count：

var cont = 0;
function register(){
..
..
.
}

这样，每次函数运行到0时都不会重置，其余的都应该有效。
