我希望你们能帮助我。我有一个php文件名login.php，在这个页面有一个提交名字和密码的表单，然后有checklogin.php连接到bd并检查用户是否存在。
问题是，当我输入有关用户的信息然后提交时，什么也没有发生。它停留在同一页面上（login.php）。
这是 login.php 中的代码：
<link rel="stylesheet" type="text/css" href="StyleSheet.css" />
</head>
<style type="text/css">
#Button1
{
width: 120px;
}
#Button2
{
width: 120px;
}
</style>
<body onload="display_ct(),display_ct2();">
<form id="form1" runat="server">
<div id="wrap">
<div id="header">
<div id="Div1">
<div class="row dropdown-container fixed">
<div class="col-220">

</a>
</div>
<div class="col-701 last">

<p class="get-in-touch">

<script type="text/javascript">
function display_c() {
var refresh = 1000; // Refresh rate in milli seconds
mytime = setTimeout('display_ct()', refresh)
}
function display_ct() {
var strcount
var x = new Date()
var horas = x.getHours();
var min = x.getMinutes();
var sec = x.getSeconds();
if (horas < 10) {
horas = "0" + horas;
}
if (min < 10) {
min = "0" + min;
}
if (sec < 10) {
sec = "0" + sec;
}
document.getElementById('ct').innerHTML = horas + ":" + min + ":" + sec + " ";
tt = display_c();
}
</script> <span id='ct' ></span>

<script type="text/javascript">

}
function display_ct2() {
var strcount
var x = new Date()
var horas1 = x.getHours() + 2;
var min1 = x.getMinutes();
var sec1 = x.getSeconds();
if (horas1 < 10) {

}
if (horas1 > 24) {

}
