Restrict content by user level

Does this snippet only allow, then, for two levels of access? If we want three, I can obviously add those levels in the drop-down registration menu, but would I simply add those options under lines 9 and 10 above? And then would I copy and insert additional instances of lines 48-51 for each level of access?

I’ve installed the code and its not working as described.

I have three levels when I assign a user to level 3 (highest) and then restrict the page to Level 2 it tells me that I don’t have access. It appears that its blocking on a 1-to-1 match. That my level can only access pages that match my level of access. The page says that I should be as a level 3 user be able to access level 2 and level 1 restricted content.

Chad here’s what I have

function my_post_access_levels(){
	return array(
		'levels'  => array(
			/**  metavalue => label **/
			'family' => 'Family',
			'investors' => 'Investors',
			'directors' => 'Directors',
		),
		'default' => 'family',
		'user_field' => 'user_level',
		'post_field' => 'post_access',
		'error_msg'  => 'Your account does not have access to this page.'
	);
}

The accounts are in order with family having the least amount of access, followed by investors and then directors.

I set up the extra fields like this.

<---- Select One ---->|,
Family|family,
Investors|investors,
Directors|directors

I believe I have it setup correctly.

I copied the code from above into the functions.php Was there something else I needed to do?

Did some more testing.

If I set my account as Director I can’t get to investor information but can get to Director.
If I set my account as investor I can both areas.

It appears that the middle level is acting as top level.

Your blog entry is updated with all the current code then, correct? So I will scrap what I did and just start from fresh! Thank you so much, to both you and Debbie, for all of this! 🙂

Ha… great — new question. How can this be applied to bbPress forums? :-/

I’m added the code snippet to my functions.php file in a custom template created with a program called Artisteer. I simply inserted it at the bottom of the file, but when attempting to log in to WordPress, I’m receiving the following error:

Parse error: syntax error, unexpected ‘}’ in /home/starprev/public_html/wp-content/themes/lmyc5/functions.php on line 1

This is fairly new to me, any help would be appreciated.

Thanks!
Sandy

This short code should work on a page right?

[wp-members status=”level1″]

Restricted content

[/wp-members]

Hi! I setup everything in this tutorial, I even created 5 user levels in the fields area and added the levels like this:

function my_post_access_levels(){
	return array(
		'levels'  => array(
			/**  metavalue => label **/
			'level1' => 'Level 1',
			'level2' => 'Level 2',
			'level3' => 'Level 3',
			'level4' => 'Level 4',
			'level5' => 'Level 5',
		),
		'default' => 'level1',
		'user_field' => 'user_level',
		'post_field' => 'post_access',
		'error_msg'  => 'Your account does not have access to this page.'
	);
}

I hope i’m doing it correct, cos when I set a level in my pages i get a message that i’m restricted and I don’t have access. I’m I doing something wrong?

Another thing I would like to know if it is possible to set user levels by user role. On my website I have user roles as member, dj, author, moderator and admin and I would like to restrict access to the pages so lower level access can’t see those higher ones, but by using user roles to give my user roles the different level access needed. Like in example member gets the level 1, dj gets level 2, author gets level 3, moderator gets level 4 and admin gets level 5.

I’m puzzled how to get this done, if this is possible!

Thanks in advance!

Chad,

First, love the plugins!

I’m not to good with code. I have taken your snippet and added up to level 5. When I load the snippet into the functions.php file (paste it after the last line of code) and upload it, it blanks out my site. What am I doing wrong?

Hey Chad,

Like many other ppl here, I’m not a developer/coder. I’m pretty sure I will have issues with the code however, I don’t even see the functions.php file. Is this supposed to be in the WP-Members Plugin Editor area? O_o

Lost… Is it renamed in an upgraded version?

Hi Chad,

I also posted on the category one, but this is more of what I’m looking for.
I’d like to do what I did here: (clientsfirst-tx.com/resources/video-portal)
I’m using a theme called Kriesi Enfold and they have portfolio elements.

Only problem is, when I implemented your code, the admin meta block does not display on the portfolio editing section.

Any help would be greatly appreciated!!

Thank you,

How would this work with the code snippet used from this page?

https://gist.github.com/butlerblog/fb7a11d4695ed4186dc2/

I have two distinct groups that view content separate from each other, setup using the snippet above

I put the code snippet into a core functionality plugin, but when I try to activate the plugin I get this error:

Parse error: syntax error, unexpected ‘=’, expecting ‘)’ in /home/bobkpxtx/public_html/testbed/wp-content/plugins/core-functionality.php on line 29

I’ve also tried putting the code directly in my functions.php file and it breaks the site.

Any Ideas?

I created user levels in the fields that are the same as the demo “Level 1, Level 2, Level 3” so I didn’t change anything.

Here’s the whole functionality plugin:

Well this is bizarre. I’ve used FTP to transfer the file, I’ve created a blank file and copied and pasted the code into it through cpanel, I’ve tried it on another test site that’s locally hosted, all with the same results. I’ve tried it with and without the comment.

I’ve tried code from other tutorials here, and they work. I’m not sure what to try next, but I will probably try another approach to creating multiple access levels, like by user group or category. They seem to work fine.

Thanks for your help.

I was using Sublime Text, which is fairly new to me, for editing. So on a wild guess I pasted the code in this thread into Coda and then copied it to the file on the site. Now it works.

Not working for me

🙁
