一些快速的PHP和HTML帮助

Question

Basically I will tell you what I want to do.

1: If a user is not logged in I want them to be re-directed back to the login page.

2: If a user is Logged in and they submitted a form I want them to be directed to the next page.

I have tried it with meta refresh but I can only seem to get it working with one or the other.

Can you please advise what the best way to do this would be ?

the code I am using at the moment is

<meta http-equiv="refresh" content="0;index.php">  
<meta http-equiv="refresh" name="myidentifier" content="0;mystats.php">  

Thanks

Use http headers instead. For example:

session_start();

//Redirect when user is not logged
if($_SESSION['logged'] != 1)
{
  header("Location: http://redirect.here.com/login.php");
  exit(0);
}

//Redirect when user sent form
if((isset($_POST['sent']))&&($_SESSION['logged']==1))
{
  header("Location: http://redirect.here.com/nextpage.php");
  exit(0);
}

Don't forget to set $_SESSION['logged']=1 after successful login. There are more methods of detecting that user sent form, but I prefer placing hidden input field with name="sent" to each form.
