重定向PHP

如何將PHP頁面重定向到另一個頁面？重定向PHP

</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>

所以當用戶登錄時，它會將它們帶到上面顯示的頁面。我需要做的是，如果登錄成功，我需要它重定向到另一個PHP頁面。

在此先感謝！

的login.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";

複製，（HTTP：//計算器。com/q/768431/425313） – 2013-03-27 22:45:27

嘗試使用header()功能如此：

if ($num == 1) 

{ 

header("Location: http://www.example.com"); 

}

明顯變化http://www.example.com到您選擇的位置，並將其放置在上面的頁面中的任何HTML，否則你將得到一個頭已經設置錯誤。

考慮到上面你需要重新安排你的代碼如下：

<?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) 
    { 
     //sends back a data of "Success" 
header("Location: success.php"); 

    } 
    else 
    { 
     //sends back a message of "failed" 
     $error = "Unsuccessful Login"; 
    } 
} 

?> 

<html> 
<head> 
</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 echo $error; ?> 

      </div> 
     </div> 
    </body> 
</html>`

此外，我促請你看看PDO或mysqli和準備的語句與綁定值與此操作前當你打開自己達到SQL injection attacks的類型的東西。

在OP的情況下不起作用; PHP代碼被埋葬的HTML標籤裏面，內容已經發送到瀏覽器 – thaJeztah 2013-03-27 22:41:50

請記住，你寫艾米HTML或echo'ed數據頁面 – 2013-03-27 22:42:09

真之前，你只能用這個，只是移到高於所有代碼HTML，編輯了答案來反映。 – 2013-03-27 22:43:05

只需使用

header("Location: http://www.test.com");

請注意，您只能設置一個頭重定向，如果沒有之前發送輸出。沒有單詞，沒有html語法，甚至沒有簡單的空白。

更多細節：header function

所以，你必須把你的腳本頂端的PHP部分和存儲的成功/錯誤的消息在一個變量，而不是直接的「回聲」。

示例：請注意if語句中的變量「$ return_message」。沒有「回聲」了，但在HTML上下文中，您會找到輸出的回顯。

<?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" 
     $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"; 
    }

如果在重定向header（）後不包含'exit;'，頁面上的其餘代碼仍然會被執行。 – Tigger 2013-03-27 23:19:41

我出事了。在php之後，我是否會開始會議？它也說未定義。標題是否在頂部。對不起，我是新來的PHP。 – user2216325 2013-03-27 23:25:52

您coud使用JavaScript

<script type="text/javascript">window.location = 'PathToYourPage.extension'</script>

這個頭文件在php頁面上？ – user2216325 2013-03-27 23:33:08

它可以去你想要的地方。它會停止頁面的其餘部分（在這種情況下使用die（））並將用戶重定向到函數中指定的位置。確保在調用函數之前沒有HTML輸出。您可以在頁面頂部放置一個ob_start（）函數來解決任何錯誤消息，說明「頭文件已經發送」 – 2013-03-28 00:18:31
