First off, it’s PHP, not Javascript.

Secondly, the “function wp_logout_url($redirect=”)” line sets up the function, where a variable ($redirect) defaults to nothing. That way, if the function is used with no input given as a value for $redirect, it won’t throw up an error that a required parameter is missing.

wp_logout_url(), anyway, is WordPress core, not the fixed function. So if you want any more explanation than that, you’d probably have to contact the WordPress dev team for why they chose to do it that way. But the most likely reason is what I have above – so you can have a defined variable (for use elsewhere) and the definition of that variable – by default – is nothing.

In the second of code where it has:

function wp_logout_url($redirect = ”)

In the parameters it has an assignment instead of a variable, why? (I’m sort of a nooby in JavaScript myself).

An alternative method would be to simply force any user who accidentally happen upon an instruction on the front end to be logged in. Actually there’s several things you could do. if you dont’ want them to be seen *at all* on the front end, you can create a custom post type template file and make the custom post type do whatever you like. Force people to log in to see it first (and compare the logged-in user’s level to the level given in the custom post type) ir simple have a default message that says “you can’t see this” or something. (maybe make it a fake 404 page.)

Those are some viable workarounds

Someone already reported to be that they are coming up in the search results. I’ve fixed that issue (it’s in the upcoming release) – so once you upgrade there shoudn’t be anyone actually viewing them from the front end (not unless you provide direct links to them) I dont’ know that there’s any method of preventing them from actually being seen on the front end (whether you know what the URL is or not) – because, as I said before, these are using the custom post type system that WordPress provides. I don’t know that there’s any method of removing permalinks from posts. But I’ll look into it.

it is a real great Plugin. I have only one problem/question: The Instructions shall be visible only to Backend-Users. Unfortunately with there Permalink they are reachable in the Frontend as well.
I tried to set it to private or password protected but then they won’t show up in the Backend anymore. Is there any way to solve that or am I just blind?!?
