PHP会话问题

更新解决了问题！

在检查代码之后，一个令人讨厌的问题是我在

之后错过了}else{} 
header ('location:referraldone.php?say=blankfields');
}

我现在真的迷失了这个会话代码。我不明白为什么会议不起作用。我哪里做错了？当有人发出错误未填写必填字段时，我正在尝试将字段中输入的数据带到下一页。代码如下：

<?php

if (!$_POST['cname'] | !$_POST['cphone'] | !$_POST['caddress'] | !$_POST['ccity'] | !$_POST['cstate'] | !$_POST['czip'] | !$_POST['cbirthday']) {

$rname = $_REQUEST['rname'];
$rdate = $_REQUEST['rdate'];
$ragency = $_REQUEST['ragency'];
$rphone = $_REQUEST['rphone'];
$cname = $_REQUEST['cname'];
$cphone = $_REQUEST['cphone'];
$caddress = $_REQUEST['caddress'];
$ccity = $_REQUEST['ccity'];
$cstate = $_REQUEST['cstate'];
$czip = $_REQUEST['czip'];
$cbirthday = $_REQUEST['cbirthday'];
$medmemid = $_REQUEST['medmemid'];
$medclaim = $_REQUEST['medclaim'];
$marital = $_REQUEST['marital'];
$income = $_REQUEST['income'];
$gender = $_REQUEST['gender'];
$race = $_REQUEST['race'];
$caregiver = $_REQUEST['caregiver'];
$relationship = $_REQUEST['relationship'];
$memphone = $_REQUEST['memphone'];
$physician = $_REQUEST['physician'];
$phyphone = $_REQUEST['phyphone'];

session_start();
$_SESSION['rname'] = $rname;
$_SESSION['rdate'] = $rdate;
$_SESSION['ragency'] = $ragency;
$_SESSION['rphone'] = $rphone;
$_SESSION['cname'] = $cname;
$_SESSION['cphone'] = $cphone;
$_SESSION['caddress'] = $caddress;
$_SESSION['ccity'] = $ccity;
$_SESSION['cstate'] = $cstate;
$_SESSION['czip'] = $czip;
$_SESSION['cbirthday'] = $cbirthday;
$_SESSION['medmemid'] = $medmemid;
$_SESSION['medclaim'] = $medclaim;
$_SESSION['marital'] = $marital;
$_SESSION['income'] = $income;
$_SESSION['gender'] = $gender;
$_SESSION['race'] = $race;
$_SESSION['caregiver'] = $caregiver;
$_SESSION['relationship'] = $relationship;
$_SESSION['memphone'] = $memphone;
$_SESSION['physician'] = $physician;
$_SESSION['phyphone'] = $phyphone;

这是应该获取会话数据并用它填充字段的错误页面，但它没有：

4 个答案:

答案 0 :(得分：3)

您的代码存在一些明显的问题：

  • 您使用的是二进制OR |，而不是||子句中的布尔值或if。
  • 您也可以extract($_REQUEST); - 而不是手动本地化变量 - 这可能是不好的建议，因为您可能无法理解完全在全局范围内运行的脚本的安全隐患。
  • 所以（更好的）替代方案是手动foreach ($_REQUEST as $key=>$value)，从而填满你的$ _SESSION。在第二个脚本中同样这样做 请记住： Foreach循环是我们的朋友。
  • 同样，html输出可以在循环中完成，从而减少整体代码大小。
  • 您可能错过了session_start，或者也可能：过早输出并收到您没有告诉我们的通知。

答案 1 :(得分：3)

在从-or写入$ _SESSION变量之前，必须先调用session_start。在第二页“错误页面”中，您放置了session_start但在尝试读取$ _SESSION var之后，将其放在“错误页面”的顶部而不是中间。

答案 2 :(得分：1)

好的，有些改写帮助。

我最终会先创建一个字段名称和标题的描述性数组。这样，您就可以获得可接受输入字段的安全列表，并在以后简化输出。

$allowed_fields = array("
      "cname" => "* Client name",  // titles may include <b>HTML</b>
      "phone" => "PHone number",
      "caddress" => "Address",
      ...
");

但是为了简化第一个脚本，您可以用以下内容替换50行$ _REQUEST输入和$ _SESSION填充：

session_start();
foreach ($_REQUEST as $field=>$value) {
    $_SESSION[$field] = $_REQUEST[$field];
}

所有表单字段输出可以通过以下方式简化：

foreach ($allowed_fields as $field=>$title) {
    ?><tr>
    <td valign="top"><?=$title?>:<br /><input name="<?=$field?>" type="text" value="<?=htmlspecialchars($_SESSION[$field])?>" style="width:98%" /></td>
    </tr><?php
}

答案 3 :(得分：0)

除了已经讨论过的内容之外：您需要将会话ID放入您重定向到的URL中，以便在无法使用Cookie时将其存在。

header ('location:referraldone.php?say=blankfields&'.SID);

即使使用 session.use_trans_sid

，也不会自动执行此操作
