Question

我对PHP知之甚少，而且我被指派去尝试解决一些在网站上不起作用的事情。该网站主要处理两个不同的用户，一个可以发布文章的交易者和一个可以发布博客的博主。当用户注册成为交易者并尝试提交文章时，该页面只会重定向到base_url.user/blogger/而不是base_url.user/trader/。我认为这是因为它并没有将用户识别为交易者。你能看一下代码吗？如果你有任何关于它为什么不起作用的想法我会接受你的想法

Answer 1

您应该确定用户是交易员还是博主，然后相应地设置适当的会话变量。根据设置的会话变量来检查哪个登录的简单if语句应该可以解决？如果我正确理解你的问题。

我建议（可能更容易）是

<强> 1。向数据库中的用户表添加一个属性，即Account_Type枚举（'trader'，'blogger'）not null 。

<强> 2。注册时，在表单中添加单选按钮，以选择他们是交易者还是博主并且显然已将此数据发送回您的数据库

第3。当他们登录时（我假设所有用户都有一个唯一的用户名）执行类似

的操作

- 将会话变量设置为0

  $_SESSION['trader'] = 0;
  $_SESSION['blogger'] = 0;

- 在数据库中查找用户名，并查找该用户名是否为交易者或博主。

//A Query to find the Account_type that goes with the input account 
$accquery = "SELECT Account_type FROM Account WHERE Account_Name =$_POST['account']";

//Running the query
$result = mysqli_query($connect,$accquery);


//Using an array to fetch the type and put it into a variables place
while($row = mysqli_fetch_array($connect,$result))
{
$acctype = $row['Account_Type']; 
}



else {
    die("Query failed");
}

然后执行类似

的操作

if($acctype == "trader") {
  $_SESSION['trader'] = 1;
elseif($acctype == "Blogger") {
  $_SESSION['blogger'] =1;
else {
  //error message
}

然后当你需要检查它们是什么时，你可以做类似的事情

 if((isset($_SESSION['trader'])) && ($_SESSION['trader'] == "1")){
   //specific code for trader
   }

您可以将其应用于博主。

我还建议你研究消毒你的输入，这很简单但非常重要。

另请注意，通过stackoverflow彻底搜索您的问题的答案，因为您很可能会找到一些东西。

- 希望这有帮助，请注意它只是粗略的，所以你必须解决它，但你应该掌握一些PHP，所以应该这样做。

Answer 2

使用SESSIONS：

在您设置的页面顶部：

<?php 
  //Check if session has not been started.
  if (session_status() == PHP_SESSION_NONE)
  {
    session_start();
  }
?>

在定义交易者或博客时的代码中：

$_SESSION['USER'] = "trader";

或

$_SESSION['USER'] = "blogger";

然后你可以执行你想要的代码：

//If it has not been set, do trader by default.
if (!ISSET($_SESSION['USER'])
{
    $_SESSION['USER'] = "trader";
}

if ($_SESSION['USER'] == "blogger")
{
   //Execute code for blogger
}
else if($_SESSION['USER'] == "trader")
{
   //Execute code for trader
}

只要您的“页面/会话”处于打开状态，会话就会存储在您的浏览器中。那些“变量”是用户特定的。

希望这有助于：）

PHP帮助，无法识别不同的用户
