无法在div中获取登录名和密码值 [英] Not getting login and password values in div
问题描述
我将isset添加到我的check.php中，以摆脱未识别的索引错误.问题是，当我在登录名和密码字段中随机输入某些内容时，我在div中什么也没有得到，这是我们的目标.我究竟做错了什么?我已经一遍遍地检查了代码，却找不到正确的答案
I added isset to my check.php to get rid of an unidentified index error. The thing is, I’m not getting anything in div when I type something random in the login and password fields which is the goal here. What am I doing wrong? I’ve checked the code over and over and I can’t get the right answer
这是我的login.html:
Here is my login.html:
<html>
<head>
<title> MYSQL </title>
<script
src="https://code.jquery.com/jquery-3.3.1.js"
integrity="sha256-2Kok7MbOyxpgUVvAk/HJ2jigOSYS2auK4Pfzbm7uH60="
crossorigin="anonymous">
</script>
</head>
<body>
<div id="status"></div>
<input id="login" placeholder="Login"><br>
<input type="password" id="pass" placeholder="Password"><br>
<button id="entry"> Login </button>
<script>
$("entry").click(function(){
$.post("check.php", {login: $("#login").val(), password: $("#pass").val()},
function(result){
$("#status").html(result);
})
})
</script>
</body>
</html>
这是我的check.php:
Here my check.php:
<?php
$login=isset($_POST['login']);
$password=isset($_POST['password']);
echo $login.$password;
?>
推荐答案
您的代码在这里有一些问题
You have a few issues in your code here
首先，您的.click无法正常工作，因为您没有正确选择条目
Firstly your .click wont work as youre not selecting entry correctly
替换
$("entry").click(function(){
使用
$("#entry").click(function(){
第二，在您的php中，您将最终只返回"true"或"false"，因为这是从isset()返回的内容
Secondly, in your php you are going to end up returning just "true" or "false" as that is what is returned from isset()
将您的php替换为
<?php
if(isset($_POST['login']) && isset($_POST['password'])){
$login=$_POST['login'];
$password=$_POST['password'];
echo $login.$password;
}
?>
这将在回显之前检查是否设置了登录名和密码
This will check if login and password is set before echoing
或者如果您想要一种更简单但更糟糕的方法
or if you want an easier but worse way
<?php
$login=@$_POST['login'];
$password=@$_POST['password'];
echo $login.$password;
?>
这只是抑制了您的错误，尽管这让人皱眉
This simply suppresses your errors, this is more frowned upon though
