[SOLVED]passing variables between pages

Ok I apologize in advance for this noob question but I haven’t found a sufficient answer yet.

If I wanted to pass a variable between modx pages, what is the best/most secure way of doing this?

for example I’m logged in as a manager, click on a users name and pass the internal key to the next page to pull up user info?

I would use session variables.

$_SESSION[’appId’] = "my_value";

Is the appId the ID of my choice? I’m not to experienced with session variables.

Can you set that via a link? I’m trying to take a list of users and when clicking on the user you’re taken to a page where info is pulled from the DB with the userid passed from the previous page. I guess I could append to querystring but that doesn’t seem that secure.

Unless I has the id.....but then I’m not sure if you could select a DB record where a value equals that to a hashed value??? Does any of this make sense because I think I’m lost!

Snippet:


HTML page:

just do

set’s up the session var(use with snippets)


to read in another page using a snippet offcourse

The session method seems like it’d be the best but I’m not sure how to set a session variable with a link? If I POST back to the page and run a case statement to look for a QS variable and then run a function to set the session var and go to next page, it seems like I’m still passing the ID unsecurely....

Why do you think that passing an ID is insecure?

It’s just a number. It does not mean anything.

I do not get how you want to set up a session variable with a link.

Do you want to pass the id via the link like: index.php?my_get_var=5? This is not using a session variable but GET requests. In this case do

You have a point about the security of a number that doesn’t mean anything on it’s own. Guess I’m just paranoid! So if I understand you right; I would have something like:



Then on my next page I’d use

in my snippet to grab the variable being passed?

That should work.
