使用Admin页面,我想打开/关闭或启用/禁用php文件,我正在使用会话,但会话在我关闭浏览器时停止。即使关闭浏览器,我也希望会话保持活动状态。我使用正确的代码吗?我认为这不是会议......?

<form method="post" action="">
    <td colspan="2"  bgcolor="#FFFFFF" valign="left">
        <strong>APPLICATION FORM:
        <select name="switch" id="switch" align="center" valign="center">
            <option></option>
            <option>ON</option>
            <option>OFF</option>
        </strong>
        </SELECT>

        <input type="submit" name="submit" value="SUBMIT">

        <?php
        if(isset($_POST['submit'])){
            include('config.php');
            $switch=($_POST['switch']);

            if ($_POST['switch'] == "ON"){
                $_SESSION['switch'] = $switch;
                echo "<script language='javascript' type='text/javascript'>";
                echo "alert('Application form ACTIVATED!');";
                echo "</script>";
                echo 'ON';  
            }

            if ($_POST['switch'] == "OFF"){
                echo "<script language='javascript' type='text/javascript'>";
                echo "alert('Application form DEACTIVATED!');";
                echo "</script>";
                echo 'OFF'; 

                session_destroy();
                header('location.href=index.php');
            }
        }
        ?>
    </td>
</form>

<?php
session_start();
?>

<?php
$con    =   mysql_connect('localhost','root','');
if (!$con) {
    die('Could not connect:'.mysql_error());
}

mysql_select_db ('psp',$con);

if (!isset($_SESSION['switch'])){
    header('location:index.php');
}
?>

您可以在保存设置时使用数据库或文件关闭/打开页面。

是的,会话可用于禁用/启用php文件,但它会在浏览器退出时重置。虽然cookie很有用,但当您清除浏览器cookie或Cookie过期时,设置将重置。

最好的方法是使用数据库或文件保存设置..

因此,您可以使用列创建数据库中的表:

select * from file_settings;
+-------+-------------+-----------+
| id    |  filename   |   status  |
+-------+-------------+-----------+
| 0     |  file.php   |    ON     |
+-------+-------------+-----------+

然后在file.php上:

<?php
  /* code for getting the columns in file_settings:
     lets make a shortcut, just query the database and
     it will output every row in the table as $row
  */
  if("file.php" == $row['filename'] && $row['status'] != "ON") {
    header('the_redirect_page.php');
  } 
  // if false then proceed to page
?>
