Global Variables

Using mck_login, I have a page where users can, well, log in. Once logged in, I save their login name to a variable so I can use it later.

<txp:variable name="activeuser" trim><txp:mck_login name="name" /></txp:variable>

<p>Welcome to your Slam Center, <txp:variable name="activeuser" />!<br>

The above does display the username correctly. However, later on down the page, I have a link the user can click to create a new league:

<a href="index.php?s=league_new">Create New League</a></p>

On the league_new page, I need the “activeuser” variable, but it’s not getting passed from the previous page.

<p>Thanks <txp:variable name="activeuser" output /></p>

I put that in as a test, and the variable has no value. What am I missing? Can what I want be done?

txp variables won’t persist across pages unless you save them in some form of persistent storage, whether in a cookie or as a database field.

I’m not familiar with mck_login, but could you not just set the variable again at the top of the page using the same code as before, e.g.

<txp:variable name=“activeuser” trim><txp:mck_login name=“name” /></txp:variable>

That would be easiest. Otherwise, the “name” of the currently logged-in user is already stored in the internal $txp_user variable, and from that you can get the “Realname” of the author:

<txp:php>global $txp_user; echo get_author_name($txp_user);</txp:php>

Note, for this you need to allow PHP in pages (+ possible articles depending on where you are using it) in the Admin › Preferences › Publish pane. If you have guest users, you should check that this doesn’t enable them to perform malicious actions.

Gotcha. Thanks for the help!

Apparently, mck_login variables don’t persist, either. I tried the $txp_user code, which worked great, except is there a way to get the login name rather than the real name?

Yes, just do:

<txp:php>global $txp_user; echo $txp_user;</txp:php>

The other variant just puts that through a function that looks up the real name.
