我正在尝试使用硬编码的用户名和密码开发一个简单登录程序。但是，我的HTML代码显示用户名和密码框，它应该重定向到PHP文件，但它不会显示我的PHP文件输出上的任何内容。这是我的HTML代码：
<html>
<body>
<form id='Login' action='homework2.php' method='POST' accept-charset='UTF-8'>
<h1>Login</h1>
<input type='hidden' name='submitted' id='submitted' value='1'/>
<label for='username' >UserName:</label>
<input type='text' name='username' id='username' maxlength="25" />
<label for='password' >Password:</label>
<input type='password' name='password' id='password' maxlength="25" />
<input type='submit' name='Submit' value='Submit'/>
</form>
</body>
</html>
这是我的php文件
<?php
function homework2() {
if (empty($_POST['username'])) {
$this->HandleError("UserName is empty!");
return false;
}
if (empty($_POST['password'])) {
$this->HandleError("Password is empty!");
return false;
}
$username = trim($_POST['username']);
$password = trim($_POST['password']);
if (($username == 'elliez' && $password == 'tr789ial') ||($username == 'greatGuy' && $password == 'abc123') || ($username == 'blogger' && $password == '23seventeen23')) {
echo "You have successfully logged in!";
return true;
}
echo "Sorry, wrong information has been entered!";
return false;
}
?>
删除homework2（）函数
<?php
if (empty($_POST['username']))
{
die("UserName is empty!");
}
if (empty($_POST['password']))
{
die("Password is empty!");
}
$username = trim($_POST['username']);
$password = trim($_POST['password']);
if (($username == 'elliez' && $password == 'tr789ial') ||
($username == 'greatGuy' && $password == 'abc123') ||
($username == 'blogger' && $password == '23seventeen23'))
{
echo "You have successfully logged in!";
} else {
die("Sorry, wrong information has been entered!");
}
?>
您需要将php文件的名称设置为homework2.php，因为此表单的操作在homevork2.php页面上执行，并删除函数homevork2（）。
