How to change an NextGEN Gallery admin menu link URL WordPress

houfton comments:

I tried adding your change_contributor_cap function to my functions.php but it did not help.

I think I understand what you are saying about the can_manage_this_gallery function but it seems to me that it does allow a user without the 'NextGEN Manage others gallery' capability so long as the user ID ($user_ID) and gallery author id ($check_ID) are the same, which they should be, eg:

in wp_users, ID = 8
in wp_ngg_gallery, gid=49, author = 8.

In any case I have tried changing the NextGEN Gallery Roles to allow Contributors to 'Manage others gallery' but it does not help either.

this seems to be working on my setup, I log in as a contributor and can edit the gallery.

Looks like this:

you could try this action instead

add_action('init','change_contributor_cap');

and reload twice and then remove it.

When I display the capabilities of the contributor role


$role = get_role('contributor');
echo "<pre>";
print_r($role);
echo "</pre>";


I get this

WP_Role Object
(
[name] => contributor
[capabilities] => Array
(
[edit_posts] => 1
[read] => 1
[level_1] => 1
[level_0] => 1
[delete_posts] => 1
[NextGEN Manage gallery] => 1
[NextGEN Manage others gallery] => 1
)

)


are your capabilities maybe different?

houfton comments:

I used your script, thanks for that, but the Roles are the same:

`WP_Role Object
(
[name] => contributor
[capabilities] => Array
(
[edit_posts] => 1
[read] => 1
[level_1] => 1
[level_0] => 1
[delete_posts] => 1
[NextGEN Manage gallery] => 1
[NextGEN Manage others gallery] => 1
)

)`

I did have `[NextGEN Upload images] => 1` as well, but turning it off did not help.

To be clear, did you get to the screen you show in http://i.imgur.com/RuhSA.jpg in one click from the Gallery menu (Gallery>Manage Gallery>Citigo gallery) or two (Gallery>Manage Gallery>Citigo gallery title>Citigo gallery)?

Dbranes comments:

yes in two clicks from the gallery menu.

Here is how it works on my install (wp 3.4.2 + ngg 1.9.6) for different nextgen-capabilites for the contributor user.


a) <em>No nextgen-capabilites:</em>

I can't access
/wp-admin/admin.php?page=nggallery-manage-gallery
I get the message
You do not have sufficient permissions to access this page.

Can't access
/wp-admin/admin.php?page=nggallery-manage-gallery&mode=edit&gid=1&_wpnonce=316a56bf7b
I get the message
You do not have sufficient permissions to access this page.


b) <em>Only 'NextGEN Manage gallery' nextgen-capability and gallery is owned by contributor:</em>

I can access:
/wp-admin/admin.php?page=nggallery-manage-gallery

I can access
/wp-admin/admin.php?page=nggallery-manage-gallery&mode=edit&gid=1&_wpnonce=316a56bf7b
where gid=1 is owned by the contributor.

c) <em>only 'NextGEN Manage gallery' nextgen-capability and gallery is NOT owned by contributor:</em>

I can access:
/wp-admin/admin.php?page=nggallery-manage-gallery
but the gallery name has no edit link .

I can't access
/wp-admin/admin.php?page=nggallery-manage-gallery&mode=edit&gid=1&_wpnonce=316a56bf7b
I get this message:
Sorry, you have no access here

d)<em> Both 'NextGEN Manage gallery' and 'NextGEN Manage others gallery' nextgen-capabilities.</em>

I can access:
/wp-admin/admin.php?page=nggallery-manage-gallery

I can access and edit
/wp-admin/admin.php?page=nggallery-manage-gallery&mode=edit&gid=1&_wpnonce=316a56bf7b
where gid=1 is NOT owned by the contributor.

ps: I use this to add/remove capabilties:

add_action('init','change_contributor_cap');

function change_contributor_cap(){
$role = get_role('contributor');

$role->remove_cap( 'NextGEN Manage gallery');
$role->remove_cap( 'NextGEN Manage others gallery');
$role->remove_cap( 'NextGEN Edit album');

//$role->add_cap( 'NextGEN Manage gallery');
//$role->add_cap( 'NextGEN Manage others gallery');
//$role->add_cap( 'NextGEN Edit album');
}

The whole point of my question is to get there in <strong>one</strong> click from the Gallery menu not <strong>two</strong>.

So, when in admin, in the Gallery menu, clicking Manage Gallery goes direct to the single gallery view.

I believe the roles / capabilities are right.

As a test, I have tried changing the can_manage_this_gallery function to:

`function can_manage_this_gallery($check_ID) {

return true;

}`

But it still does not work.

Dbranes comments:

yes I know ;-)

but my idea was to tackle this problem first:

<blockquote>But it does not work when I test it as a Contributor. Although the URL it generates looks about right (eg .../wp-admin/admin.php?page=nggallery-manage-gallery&mode=edit&gid=2&_wpnonce=3f4a3b0ef4), it gives a "You do not have sufficient permissions to access this page." message.
</blockquote>

by adding the correct role to the contributor.

The link you provide works directly on my install with the added 'NextGEN Manage gallery' role.

Are you using some role plugins?

Have you tested this on another wp install?

houfton comments:

As I said to Arnav the pasting-link-test works for me too if there is no link hack in place. The problem seems to be only when the link hack is being used.

Did you try using Martin or my hack to admin.php to enable one click access to the single gallery view?

I am using a pretty clean test install of WP without any other role plugins but will try a fresh install...

Note to self: I must learn to use the correct code blocks on this site, not back ticks!

Dbranes comments:

this works for me:

(I just add a new submenupage here named "Manage Gallery test" to test)

add_action( 'admin_menu', 'add_menu_extra',99);
function add_menu_extra(){
global $current_user, $wpdb;
get_currentuserinfo();
$user_gallery = $wpdb->get_var( $wpdb->prepare( "SELECT gid FROM tfl_ngg_gallery WHERE author = %d", $current_user->ID ) );
add_submenu_page( NGGFOLDER , __('Manage Gallery test', 'nggallery'), __('Manage Gallery test', 'nggallery'), 'NextGEN Manage gallery', 'nggallery-manage-gallery&mode=edit&gid=' . $user_gallery,'show_menu');
}

i.e. one click away from the contributor's gallery edit page.

houfton comments:

That works!

It is much better than hacking the admin.php file. I just need to serve the new test menu item to Contributors only and get rid of the old one.

Thank you.

Dbranes comments:

Here is a method that works for me:

I just use a redirect when the current user has a role as a contributor and clicks on this link

/wp-admin/admin.php?page=nggallery-manage-gallery

and redirct to

/wp-admin/admin.php?page=nggallery-manage-gallery&mode=edit&gid=1

where gid=1 is the contributor's gallery

so this way I don't need to modify the submenu.

add_action( 'admin_menu', 'add_menu_extra',99);
function add_menu_extra(){
global $current_user, $wpdb;
get_currentuserinfo();

// only for current users that have the "contributor" role
if( array_shift($current_user->roles) == "contributor"){
$user_gallery = $wpdb->get_var( $wpdb->prepare( "SELECT gid FROM tfl_ngg_gallery WHERE author = %d", $current_user->ID ) );
// redirect to the contributor's gallery edit page when the url is
// /wp-admin/admin.php?page=nggallery-manage-gallery
if(isset($_GET['page']) && $_GET['page']=="nggallery-manage-gallery" && !isset($_GET['mode']) ){
$redirect_url = get_admin_url()."admin.php?page=nggallery-manage-gallery&mode=edit&gid=" . $user_gallery;
wp_redirect( $redirect_url, 301);
exit();
}
}
}


Dbranes comments:

ps:

you just have to replace tfl_ngg_gallery with wp_ngg_gallery ;-)

(or adjust to the db prefix you have)

houfton comments:

That is an even better solution. I was having trouble hiding the original link from Contributors. I have used a separate getext() function to change the new link label to "Manage Images" which makes more sense.

I did spot the tfl_ngg_gallery issue, thanks!

Dbranes comments:

ok, great ;-)
