如何从 PHP 页面重定向到另一个页面？
</head>
<body>
<!-- Home -->
<div data-role="page" id="page1">
<div data-theme="a" data-role="header">
<a data-role="button" data-theme="d" href="login.html" data-icon="arrow-l" data-iconpos="left" class="ui-btn-left">
Back
</a>
<a data-role="button" href="index.html" data-icon="home" data-iconpos="right" data-theme="d" class="ui-btn-right">
Home
</a>
<h3>
Login Process
</h3>
</div>
<div data-role="content">
<?php
// takes the variables from action script and assigns them php variables names
$user = $_POST ['username'];
$pass = $_POST ['password'];
// if there is a user name and password
if ($user && $pass)
{
// connect to server
mysql_connect("localhost", "", "") or die(mysql_error());
//select database
mysql_select_db("") or die(mysql_error());
//Create a query that selects all data from the PATIENT table where the username and password match
$query = "SELECT * FROM Patient WHERE Username = '$user' AND Password = '$pass'";
//executes query on the database
$result = mysql_query ($query) or die ("didn't query");
//this selects the results as rows
$num = mysql_num_rows ($result);
//if there is only 1 result returned than the data is ok
if ($num == 1)
{
//sends back a data of "Success"
echo "Successful Login";
$row=mysql_fetch_array($result);
$_SESSION['Name'] = $row['Name'];
$_SESSION['Address'] = $row['Address'];
}
else
{
//sends back a message of "failed"
echo "Unsuccessful Login";
}
}
?>
</div>
</div>
</body>
</html>
因此，当用户登录时，会将他们带到上面显示的页面。我需要它做的是，如果登录成功，我需要它重定向到另一个 PHP 页面。
登录.php
<?php
// takes the variables from action script and assigns them php variables names
$user = $_POST ['username'];
$pass = $_POST ['password'];
$error = '';
// if there is a user name and password
if ($user && $pass)
{
// connect to server
mysql_connect("localhost", "", "") or die(mysql_error());
//select database
mysql_select_db("") or die(mysql_error());
//Create a query that selects all data from the PATIENT table where the username and password match
$query = "SELECT * FROM Patient WHERE Username = '$user' AND Password = '$pass'";
//executes query on the database
$result = mysql_query ($query) or die ("didn't query");
//this selects the results as rows
$num = mysql_num_rows ($result);
//if there is only 1 result returned than the data is ok
if ($num == 1)
{
header("Location: http://helios.hud.ac.uk/u101010/PHP/details1.php");
}
//sends back a data of "Success"
$return_message = "Successful Login";
$row=mysql_fetch_array($result);
$_SESSION['Name'] = $row['Name'];
$_SESSION['Address'] = $row['Address'];
}
else
{
//sends back a message of "failed"
$return_message = echo "Unsuccessful Login";
}
}
