Answered Login.login 1.8.1: Can redirectToPrior=`1` be overrriden in certain cases or is this a bug?

That's definitely worth a try. I thought of it but, for some reason, thought it wouldn't work. I can't remember why I thought that.

Sorry for delaying so much in replying to this thread. I had to solve some unrelated issues that took most of my week.

I tried to do what I had said in my previous post and created a PreHook that read the $_SERVER['HTTP_REFERER'] variable and stored it in a session variable of my own: $_SESSION['CallingPage'], like so:



In order to read the value and check if it was correct first, I created a snippet and placed it in my members page (which in this example is accessible after logging in and then clicking on another link to ensure that my referer has changed) to read the session variable and display it with a placeholder:



For some reason, I was always getting this value: http://www.<mysite>.com/index.php?id=1

But id=1 is my login page, not its referer.

I thought this was because the form had already been processed and maybe the HTTP_REFERER value had already changed, so instead of running my snippet as a PreHook, I renamed it 'SaveReferer' and loaded it as a separate snippet in my login page and placed it before the login snippet:



But after doing that, I'm still getting the referer page as: ...index.php?id=1

Is there something in ModX logic that I'm missing, or should I look for another variable instead of HTTP_REFERER? (I know Login must save that value somewhere else too before processing the form, but I don't know where that is).

Thanks in advance!

The Login page is a form that submits to itself, so when you click on the Login button, SaveReferer will execute again with (I think) the Login page as the referer.

If you put the SaveReferer tag below the Login tag, it should only execute once, but it should also make sure not to set the $_SESSION variable if it's already set (in case the user enters the wrong info and the page reloads).
