$f = "Error 404 Page Not Found";
if(isset($_POST['submit'])){

.phpphphtml if ($a == $c && $b == $d )
{
header("location: newpage.php");
exit;
}

}
或者确实如上所述，我将表单重定向到新页面首先，这将是
htmllogin.html<!doctype html>
<html>
<body>
<form action="login.php" method="post"><!-- if you will not give action then form will posted to the same page -->
<input type="text" name="username" placeholder="Enter The Username"><br>
<input type="password" name="password" placeholder="Enter Password"><br>
<input type="submit" name="submit" value="Login">
<input type="reset" value="Cancel"><!-- about this i cannot say anything -->
</form>
</body>
</html>
<?php
$original_user_name = 123; // take variable name that are self descriptive
$original_user_password = 234;
$form_username = $_POST["username"];
$form_password = $_POST["password"];
// $e = "Hello World!!"; no need of extra variable
// $f = "Error 404 Page Not Found"; no need of extra variable
if(isset($_POST['username']) && isset($_POST['password'])){ // check with POSTED values not with button value
if ($original_user_name == $form_username && $original_user_password == $form_password){
echo "hello World!";
}else{
echo "Error 404 Page Not Found!";
}
}else{
echo "please fill both user name and password!";
}
?>
注意：-两个文件必须在同一工作目录中。将php代码放在其他页面中，并在
$c$username$password$d方法
