Question

我在config.php文件中使用session_start（）函数，此文件包含在所有文件中。在我的add_page.php页面中，我在会话中提交表单并保存消息（在提交操作中），然后重定向到index.php页面（使用标题（'location：...'））。但在重新指导后，我没有从会话中收到消息。其他会话数据存在像-user，logged_in等任何想法???

代码吼叫（add_news.php）。提交表格后，它会重新定向到news.php。 config.php文件顶部有session_start（）函数，它包含在每个页面中：

    <?php
include('../include/config.php');

//submit edit data
if (isset($_POST['submit_edit'])) {
    $news_head = stripslashes(trim($_POST['news_head']));
    $news_details = $_POST['news_details'];
    $news_special = ($_POST['news_special']=='')?'0':'1';
    $news_status = ($_POST['news_status']=='')?'0':'1';
    $data = array('news_head'=>$news_head,
                'news_details'=>$news_details,
                'news_special'=>$news_special,
                'news_status'=>$news_status);

    $clause = "news_id = '".$_POST['news_id']."'";
    $response = update_data('news', $data, $clause);
    if($response)
    $_SESSION['success_msg'] = "News updated successfully.";
}
//submit edit data end
?>
<form action="add_news.php" method="post" id="add_news_form">
<input type="hidden" name="news_id" value="<?php echo $news_id ?>" />
<table width="100%" border="0" cellspacing="4" cellpadding="4">

  <tr>
    <td>News Heading</td>
    <td><input type="text" name="news_head" id="news_head" class="required" value="<?php echo $news_head ?>" size="100" /></td>
  </tr>

  <tr>
    <td>News Details</td>
    <td><textarea name="news_details" id="news_details" class="editor required" rows="7" cols="60"><?php echo trim(stripslashes($news_details)); ?></textarea></td>
  </tr>
  <tr>
    <td>Special News</td>
    <td><input type="checkbox" name="news_special" id="news_special" value="1" <?php if($news_special=='1') echo 'checked="checked"'?> />
[ Checked means special ]</td>
  </tr>
  <tr>
    <td>Status Status</td>
    <td><input type="checkbox" name="news_status" id="news_status" value="1" <?php if($news_status=='1') echo 'checked="checked"'?> /> 
    [ Checked means published ]</td>
  </tr>
  <tr>
    <td>&nbsp;</td>
    <td><input type="submit" value="Submit" <?php if($_REQUEST['news_id']!="" && $_REQUEST['action']=='edit') echo 'name="submit_edit"'; else echo 'name="submit"'; ?> /></td>
  </tr>
</table>
</form>

Answer 1

确保在任何在会话中保存消息的呼叫之前发生对session_start()的呼叫。必须在每个需要会话的页面请求上调用session_start()，并且必须在页面的最开始发生，甚至在提交操作发生之前。
