Question

我在网站登录脚本上注册会话时遇到问题：所以事情是这样的，我正在使用webmatrix在我的网站上工作，我在两台不同的计算机上处理相同的文件，我也将网站上传到服务器。在所有三种情况下，它工作得很好！最近我在笔记本电脑上创建了相同的工作环境，webmatrix + xampp mysql db - 只有在这里我发现会话拒绝创建，代码：

（登录页面包含在index.php页面中。

<?php
session_start();
$no_mail_pass_error="";
$no_user_error="";
$wrong_pass_error="";

if ($_POST['submit_login']){

$log_email = $_POST ["log_email"]; //VAR $email = to what usename has entered
$log_password = $_POST ["log_password"]; //VAR $password = to what usename has entered
$remember_me = $_POST ["remember_me"];

$log_email = strip_tags($log_email);
$log_password = strip_tags($log_password);

$log_email = mysql_real_escape_string($log_email);
$log_password = mysql_real_escape_string($log_password);

if ($log_email==""||$log_password=="") {
$no_mail_pass_error='
    <div id="login_errors_div" style="display:none;">
    <table border="0">
    <tr>
    <td>
    <img src="ec_mark_25.png"/>   
    </td>
    <td>
    no mail    
    </td>    
    </tr>
    </table>
    <hr />
     </div>

     ';
}
else {

$login_connect = mysql_connect ("***", "***", "***")

or die ("couldnt connect");
mysql_select_db (***) or die ("not found"); //if db was not found die
mysql_query("SET NAMES 'utf8'");

$login_query = mysql_query("SELECT * FROM users WHERE email='$log_email'"); //search for specific username entered

$login_numrows = mysql_num_rows($login_query); //check that it appears AT LEAST in ONE row

if ($login_numrows!=0) // IF IT APPEARS IN NONE - NO USER EXISTS

    {

    while ($row = mysql_fetch_assoc($login_query)) //Takes the whole row of the specific user and extracts all the fields
    {
        $dbemail = $row['email'];
        $dbpassword = $row['password']; //Sets thoes fields into variables
        $id = $row['id'];
        $log_firstname = $row['firstname'];
        $log_lastname = $row['lastname'];
    }

    if ($log_email==$dbemail&&md5($log_password)==$dbpassword)

    {

    if ($remember_me=='on') {
    setcookie ("email",$email,time()+604800);

          session_register('email');
          $_SESSION['email']=$log_email;

          session_register('id');
          $_SESSION['id']=$id;

          session_register('firstname');
          $_SESSION['firstname']=$log_firstname;

          $_SESSION['lastname']=$log_lastname;

    header ("Location: homepage.php");
    }
    else if ($remember_me=='') {

什么可能阻止会话注册？

Answer 1

发表评论作为答案;）

检查您的PHP版本（我相信它们与这两种环境不同）。

自PHP 5.3起，

session_register已被弃用，并且已删除PHP＆gt; = 5.4。只需删除session_register并使用$_SESSION['key'] = "value";代替。

请参阅session_register文档。

Answer 2

检查PHP保存会话数据的位置。你可以用phpinfo（）找到它，你可以在php.ini中更改它。我认为它叫做session.save_path，并确保apache用户（或任何Web服务器）具有对该目录的写访问权。

会话寄存器不起作用
