Returning to user to their topic after creating it

[Eiolon]

When someone makes a reply to a topic in my forum I have a session variable setup to direct them back to the topic after it's been submitted.  I do this by using:

 

if (isset($_GET['topic_id'])) {
$_SESSION['topic_id'] = $_GET['topic_id'];
}

 

The problem I have is when I want to create a new topic rather than post a reply.  The topic_id has not been created yet so therefore I can't set a session to it.  I'd like to have the user taken to their topic after it's been created.

 

Any ideas on how to accomplish this?  Thanks!

Try...

 

if (isset($_GET['topic_id'])) {
$_SESSION['topic_id'] = $_GET['topic_id'];
}
else
{
  if(isset($_GET['topic_name']))
  {
    $query="select topic_id from topics where topic_name = $_GET['topic_name']";
    // etc
  }
}

How does setting a session bring you back to a topic when you post in it? ???

Anyone? I need a better way than having them wait for the page to refresh

somehow youll have to create a variabel that stores boolean:  reply or new post.  once youve validated that its a new post ( no set Topic_ID) - then you add code at the top of the page to where its all sent.  that page will submit the post - and retrive the ID back out again.  I have to do it for my create user script.

 

eg:

 

NEW POST    ==>      SUBMIT POST TO DATABASE    ==> retreive the ID  again      ==>  WRITE TO SESSION VARIABLE

 

 

Instead of using a timestamp to get that POST, why dont you use that first 10 characters of the message, because theyll still be stored in $_POST variables on that script?

 

 

eg

 

 

$Message  $_POST['MESSAGE'];

 

### WRITE THIS TO DATABASE

 

$SQL = SELECT * FROM POSTS WHERE MESSAGE == ".$Message";

### RUN ANOTHER QUERY...... and youll have your message data again with the database auto increment values etc.

 

 

 

 

Hope this helps

I still don't see how making it a session takes you back to your post...like I have a refresh tag to go back to the thread...

As long as nothing has been sent to the browser yet you can use the header() function, something like this:

1. User makes a new topic/replies to a topic
2. Script adds the topic/reply
3. Use something like this to redirect...
   header("Location: readtopic.php?topic=".$topicID);
   exit;
