user access level: allow one category to post

raminrahimi · 2014-12-29 09:10:38

Hi TXP team,
Is it possible in textpattern: Allow a specific user to post articles and images in a specific category ?
It mean i need to have a user to allow just managing articles and images with specific category, no other permission allowed.

Hi Ramin,

this can only be done via CSS, as far as I know, which can of course be sidestepped by clever users.
You need the plugin bot_admin_body_class and then set up a selector similar to this one:

#page-article.restricted-user #categories_group select#category-1 option:not([value="meaningful-labor"])  {display:none;}

Note the class .restricted-user which later has to be replaced by the user name class.

See also caniuse.com/ for the applicability of the :not() selector.

It is worth warning that somebody with disabled js would be able to reach the whole content.

it mean CSS will hide the classes, if some one know firebug or any other tools easily they can enable that by CSS display, am I true ?

In FF, View > Website Style > No Style is sufficient, not even Firebug is necessary, yes.

Here I meant “with existing plugins”, no plugin I know of that’d remove categories from the cat dropdown on a by user base and server side.

If you’re able and willing to experiment, you should be able to write a plugin that replaces the category drop-down and outputs just a single category if that user is logged in:

You could use rah_status_dropdown as a starting point. That provides a replacement UI for the status radio buttons using a dropdown menu, and uses the following plugin pluggable_ui hook: article_ui / status. Another of jukka’s plugins, rah_section_titles, uses the same principle to replace the section drop-down.

For the category drop-down you need article_ui / categories. You can see how the existing category drop-down is made in the source of /textpattern/include/txp_article.php

You’ll probably need to replicate it with a modified function that returns only the category you want if $txp_user matches a certain AuthorID or list of IDs, or alternatively, if you’re limiting access to a certain user privilege type to return your designated category if the privs of that user match a certain kind of user, e.g. here’s an example function to determine if the currently logged-in user is a staff writer:

function is_staffwriter()
	{
		global $txp_user;

		if (safe_field('privs', 'txp_users', "name = '".doSlash($txp_user)."'") == 4)
		{
			return true;
		}

		return false;
	}

and here’s how it’s used in principle (code from an older manually-modified version of txp from before the days of pluggable_ui) to replace the standard category drop-down.

if (is_staffwriter() and ( ($pull == false) or ($AuthorID == $txp_user) ))
		{
			… code for designated category …
		}
		else
		{
			… code for usual category drop-down …
		}

Sorry that these are only pieces of the puzzle but maybe some of that helps…
