[resolved] Icons for User Roles (16 posts)

    I have a fairly simple question which is either so simple that no one seems to have bothered asking it, or it simply hasn't come up before. I'm introducing a special user role to my site, the "Gold Member," which is for people who have chipped in a few bucks to keep it going. I'm using Role Scoper to create a few simple, members-only areas of the site, and thus far it's all working fine.

    But there's one thing I can't figure out: I'd like to give "Gold" users special icons -- a tiny gold star, say -- next to their user names in the comments to note their special status (think TOTALFARK). Obviously, this would be tied to calling their role somehow, but I know so little about PHP that I can't wrap my head around it.

    I gather the solution is obvious, but I can't figure out how to do it.

    I'm not sure if it's relevant, but I'm using the Magazine Basic theme.

    Thanks, and that's clearly one important piece of the puzzle.

    For anyone else who is reading, here's what I'm looking at ...

    <?php
    $user = get_userdata( $user_id );

    $capabilities = $user->{$wpdb->prefix . 'capabilities'};

    if ( !isset( $wp_roles ) )
    $wp_roles = new WP_Roles();

    foreach ( $wp_roles->role_names as $role => $name ) :

    if ( array_key_exists( $role, $capabilities ) )
    echo $role;

    endforeach;
    ?>

    I'm still left with how to make that into something that only outputs info for a specific user role (ignoring all the rest), and then displays that as an image, rather than text. So, if there's a "Gold" member comment (and only in that case), it displays a small icon.

    I'm using Role Scoper to define the new roles, but I need help with the code to get the role-specific icon to display in the comments next to the user name. I know where it goes in the CSS, but now how to call just the one user role and turn it into an icon.

    I've never used Role Scoper just heard about what it can do before.

    Curious if when you apply your "Gold Member" role to a username. Does it say Gold Member or something under or next to their name to signify that user having a different set of credentials?

    Using this ...

    <?php
    global $wp_roles;

    foreach ( $wp_roles->role_names as $role => $name ) :

    if ( current_user_can( $role ) )
    echo 'This user has a role of ' . $role;

    endforeach;
    ?>

    It outputs this ...

    This user has a role of gold

    For clarify, it outputs whatever the user role's name is for each user comment. Clearly, this is a step in the right direction. What I need to do is make it only output something for "Gold" members, and then to display an image on the page, rather than just the role title.

    OK, I think I'm making some progress. My obvious ignorance of PHP will, I'm sure, cause much eye rolling, but hopefully I'm not the only person who has run into this problem.

    <?php
    global $wp_roles;

    foreach ( $wp_roles->role_names as $role => $name ) :

    if ( current_user_can( $role ) )
    echo '<img src="http://somesite.com/image.gif">' ;

    endforeach;
    ?>

    This now outputs the image. If someone could just tell me how to restrict the query above to just one specific user group, I'd be in business.

    If the code you posted (which I haven't tested) prints each user's role, then can't you just modify it like this?

    <?php
    global $wp_roles;
    
    foreach ( $wp_roles->role_names as $role => $name ) :
    
    if ( current_user_can( $role ) && $role == 'gold' ) {
        echo '<img src="/gold_member.png" alt="" />';
        break;
    }
    endforeach;
    ?>

    That way, it doesn't print anything unless $role is equal to 'gold'. And you can make the 'echo' statement print whatever you want. In the example above, it prints out an image tag, but you could have it print a CSS class name or whatever else you want.

    Howdy, vandahm!

    It's clearly doing something with the user level, but not what I was going for. When I'm logged in as a "gold" member, I can see the icon, but it's on all of the posts, not just the "gold" ones. If I'm logged in as anything else, I can't see the icon on any posts, even ones I know to be "gold."

    And if I'm not logged in, I get an "Invalid argument supplied for foreach()" error. At first I thought it was because of the user role, but I get the same error when I change it to "editor," for instance.

    Maybe I'm going about this all wrong. From the thread linked to earlier ...

    <?php
    $user = new WP_User( $user_id );

    if ( !empty( $user->roles ) && is_array( $user->roles ) ) {
    foreach ( $user->roles as $role )
    echo $role;
    }
    ?>

    This outputs nothing for me, logged in or not, but I gather that's because of the $user_id not being a specific ID. Is there some way of tweaking this to output specific user roles?

    OK, mostly solved thanks to this thread: http://wordpress.org/support/topic/261086?replies=3

    <?php $user_info = get_userdata($comment->user_id);
    
    					if ( $user_info->user_level == 10 ) {
    							echo('<img src="/gold_member.png" alt="" />');
    					} ?>

    This is set to display the "administrator" role, and finding the right user level for the new, specially created role might be difficult (I might just co-opt "contributor," since it has a numeric equivalent, and my site doesn't really use that role at present.

    This appears to work when logged in under any role, or when logged out.

    Am I missing something?

    User levels are old and busted (from pre-WP 2.0 days). I wouldn't recommend using them because they are not an accurate representation of any role if you have anything other than the default WP setup.

    The thread I pointed you to had your answer. The easiest way to do it would be to drop something like administrator.png into your /images folder (same with other roles):

    $user = new WP_User( $comment->user_id );
    
    if ( !empty( $user->roles ) && is_array( $user->roles ) ) {
    	foreach ( $user->roles as $role )
    		echo "<img src='/path/to/images/{$role}.png' alt='{$user->display_name}' />";
    }

    If you just wanted to check for a single role, just use:

    if ( 'administrator' == $role )

    Thanks, greenshady. Again, I'm probably missing something, since I'm woefully ignorant of php. I did try solution you suggested, but it didn't work. This is probably because I'm misunderstanding something, but if you'd humor me just a little further, it'd be of great help.

    When I use this ...

    <?php $user = new WP_User( $comment->user_id );
    
    if ( 'administrator' == $role ) && is_array( $user->roles ) ) {
    	foreach ( $user->roles as $role )
    		echo "<img src='/image.gif' alt='{$user->display_name}' />";
    } ?>

    I get this ...

    Parse error: syntax error, unexpected T_BOOLEAN_AND

    Sorry for all the confusion, and thanks for putting up with my ignorance. I had a friend explain the greenshady's code to me piece by piece, and now I've got it working just fine. All it took to make the whole thing work perfectly were some transparent images for the user roles I don't want icons on.
