The Joomla! Forum ™

Hi, today i stumbled on following error (if it is an error):
i need to create a user that is able only to edit articles on my website. He shouldn't be allowed to do anything else. So i added him to "Manager" group and specifically set permissions of this group so that he is denied to configure, create, delete and publish/enable any article. He has an access to and can edit any article.

The problem is: with permissions set like that the user is unable to edit any article, because category dropdown list is empty which in turn rises an error of incorrectly filled form (completly true as no category is set).

Additional fun fact: when i give the user permission to create articles categories are listed in the form (while editing an existing article).

In short: being unable to create an article makes the user unable to edit an article.

Is there any reasonable explanation to this? Or, perhaps, a way to fix it? My guess is that sth is wrong with conditions to display category list. In which file should i look for it?

What i tried:
- updating joomla! from 1.7.2 to 1.7.3
- having lots of fun with setting and unsetting permissions

You want a user to be able to edit Articles but not be able to create any ?

That appears to be illogical for hierarchy but it is possible. I just tested and Deny create (Article manager Options) prevents the Manager from creating Articles in the front end an from inside Admin.

Which Options screen are you editing ? Have you got the User in more than one User Group ?

Addendum
It's easier to set create a Group with the Manager group as Parent then edit the permisions of the new group.
Also it's easier to select a Group one level lower than the Permissions you need then add the extra. By selecting a Group with more privileges and removing them is more work and can often mean that some privileges are missed when being removed.

Hi. Thank you very much for your answer.
Yes, if I deny the user to create articles (in article manager options) he can't create articles. But it also make scategory dropdown list empty, so the user is unable to do any editing. Perhaps it will be better explained with picture:

Permissions for user set in article manager options:
http://dl.dropbox.com/u/17677544/joom_user_priv.png

As you can see, he should be able to edit.

Editing article:


Category list is empty. User can edit all articles, but can't save changes, because the form is filled incorrectly.

The user is only in the Manager group.
It is the same if I create new user group, as you suggested, and add permissions to it.
No difference between changing permissions in global config and in article options.

I managed to walk around the issue partialy.
I set all the persmissions for manager group as inherit (as they are defaultly not allowed to create) and then i set permissions in categories (one at a time) that allowed the user to create articles within given category. Not exactly elegant but it got rid of "new article" button in control panel and corresponding option in menu. Only icons in article edit form reveal that user has ability to create new article ("Save & new", "Save as a copy").
So, the problem is generally solved, but if you happen to know a better solution to it, please share

Again, thank you for your help

That appears correct because if a User is denied Create then to choose a Category to save it to would be (in essence) creating in a Category. But I will check further.

That would appear correct if the User was creating new article in category or transfering existing article from one category to another. Then Create permission would be required - i totally agree with that. But while editing an article that already is in a category, User should be able to save changes made to that article in that very category. In my view there should be exactly one position in category dropdown menu - name of the category that article already belongs to.

Thanks for looking into that.

That thought came to me as well and have asked in bugsquad groups to see what the official answer is.

Personally
As a site Owner
If I didn't trust a user to create Articles I would not trust them to edit Articles edited by SU's or other users.
As a user
If someone who did not have create rights edit one of my Articles then grrrrrrrrrrrrrr how dare they

But the consensus appears to be that Edit Articles but not Create Articles should be allowed and not having the category (it belongs to) is a bug. It is being looked into.

Thanks for your time, Webdongle.
Just to clarify: "the user" is a customer that has paid for five tab website. Working with him was not a pleasant experience, so he is not going to have sixth tab, even if I have to rewrite whole Joomla, solely for that purpose

Cheers!

Like I said

But the consensus is that it should be allowed. Someone has said they will look into it. Not sure how long it will take.

I need this fix also.

My application is that I want to make a page for my user to be able to control, and only that one page as it sits. Definitely cant do that now, its creating a hang up on my development.

Is it possible at all to edit / submit an article on frontend by users? I tried many tomes and many people too and in vain. No matter how you set permisiions you have nothing. What should I do to be able to solve this problem? I mean Joomla 1.7 .

Sure. I have mine set up for that right now. I made the user an author and on the permissions for editor set to edit allow which is default.

To submit new article, make sure create is set to allow for the permissions of users you want to create and create a menu item type as articles > create new article.

Unfortunately, right now if you want it so a user can not create a new article and edit only their own articles (ie, a page is made for them by the admin and the admin sets them as owner), when the user goes to edit this page, it can not be saved because the category for the article blanks out and does not populate appropriately (waiting for a fix)

Yes, front end editing is possible. Try with a standard Template to see if you can get it to work.

It gives 404 no matter who is logged into the front. Superuser - 404 if I want to "Submit an article" using button in User menu.
Beez 20 is a standard template for J1.7

Ive got a similar issue.

I have two groups Author and Publisher. I only want the author's to be able to create articles and the publisher is the one that edits and publishes said articles.
but when I give the publisher edit permissions at the article level it gives them edit permissions for that category as well (where they are able to edit the name of the category)

Apparently they are aware of this issue but have not fixed it yet...Waiting for fix myself.

I have now everything perfect. Just a fresh installation. Some extension made the problem. They are having them definitely too many on Joomla Extension We mustn't install ALL !!!!!!!!!!!!!

The rest of us are still waiting for a different fix.

Is there a solution to this? I have the same problem. Using the standard Beez 20 template while just setting up the site. No additional extensions installed.

When I log in as a Superuser, I have full control over everything from the front end. When I log in as a Registered user (from the front end), however, I can access the create article form, but the Category drop down displays no categories, so I cannot submit the form.

Permissions for Registered users are set to allow Create and Edit Own across the site, I even doubled checked that it was set that way in Categories and Articles.

If you want Registered users to edit but not create then just set the Permissions in the category you want them to edit or ... in Global configuration. You could also create a user group with Registered as parent.

See http://docs.joomla.org/Access_Control_L ... 5/Tutorial for tutorial.

Ah, I guess I misread, because there were other responses in this thread. I want users to be able to both create and edit their own articles, but the problem is that with both Create and Edit Own set to allowed across the board, for some reason the Category drop down is still empty.

Then just do as above but edit the Permissions to suit


A screen shot of that would help.

I'm sorry; thanks for helping, but why is it that responses completely ignore what I've stated - twice - that I've done? I HAVE edited permissions, and I even explicitly said what the permissions were set to, but since I am obviously not to be believed, here are the requested screenshots. I could have just as easily referred to the screenshots already posted above.

Permissions for Registered Users, as stated before, set to allow Create and Edit Own


Category Down Empty when logged in on the front end as a Registered user.

It is not a matter of not believing you. I was not understanding fully what you meant. Now I see because of the second image. I can now experiment with some settings on my test install.

just a few more questions (so I can 'see' your site in my minds eye)

• How are you reaching the edit screen, menu item ... clicking edit on an Article/Category ... ?
• Have you tried with different Templates ?

Addendum
Global settings

Front end

Menu item used to reach the edit screen

Just checking in to update that these were already both global permissions as well as set for articles as well. It did not matter which theme I used, same results, unless I was logged in as an administrator. I gave up.

PM me a SU login and I can take a first hand look ?
