How increase characters for admin only ?

dondomainer

Hello everyone I have a problem with the character limit for admin, I have to publish a post with rules and manuals but exceeds the character limit, at first it was a good idea increase the limit, but this rule affects everyone and I do not think anyone need to write so much, then my question is :

How increase characters for admin only ?

Thank you very much.

You can store configuration changes without saving to disk. This is how perks work in Yaga. The basic gist is:

public function userModel_afterGetSession_handler($sender) {
    $user = &$sender->EventArguments['User'];
    if(!$user->Admin) {
        return;
    }

    SaveToConfig('Vanilla.Comment.MaxLength', '20000', array('Save' => FALSE));
}

The key take away is that you are modifying the configuration in memory after a user session is loaded that is an admin.

Very interesting! And when are these changes in memory automatically wiped out? After the user logs off, after a specific editing is complete?

And while this change is done only when the admin calls it, does it affect other users who are running at the same time?

It exists only for sessions that are started with a User whose admin field is non-zero. This will generally only be for 2 accounts (the original super-user and the system account).

Just to ensue I understand this correctly:
1. The code (which tests that the user is defined as admin) changes the settings only for the user that executes the code.
2. Once executed it exists just for the user that satisfies the test in #1 above.
3. #2 implies that other users running at the same time are not affected (and in essence it tells me that each user has its own memory image of the configuration)
4. Other configuration changes can also be changed in memory only (I can pick anything on the config file).
5. For #4 above, I could make the changes based on other tests (not necessarily the one in #1 above). For example, I could test if the user is in a mobile device, has a specific role (not admin), etc.
6. The code (test + statement) need to be embedded in a plugin (any suggestion which to pick? Is there an "empty" plugin template)

You have become my mentor;-)

1-5: Yes

Thanks @hgtonight ! I'm learning to appreciate Vanilla more and more! And I'm encouraged that I was right on all of my five "speculations". I think I'm going to buy a lottery ticket this week;-)
