Different Blog Title per User Group using Genesis Child Theme WordPress
I am trying to use newly created code to filter the site's title and to show a different title per Role Scoper User Group. I already have the Role Scoper Function to grab the RS Scoper thanks to help here. But now I need to show a different blog site title per Role Scoper user group in my Genesis theme. This is the code I have so far in my child theme's function file:
/*Role Scoper User Group Grabber using Widget Logic*/
function is_usergroup_can($groupid) {
global $wpdb, $user_ID, $user_identity; // make several variables accessible using global for custom function
// $wpdb The $wpdb object can be used to read data from any table in the WordPress database,
$custom_query = $wpdb->get_row( $wpdb->prepare("SELECT * FROM $wpdb->user2group_rs WHERE user_id = '".$user_ID."'") );
if($custom_query->group_id == $groupid)
return 1;
}
/* Different Titles based on user group */
add_filter ('genesis_site_title', 'title_for_group_nine');
function title_for_group_nine (){
// print site_title of choice
if(user_group_can('9')) {
$uglinka = '<a href="http://domain.com">Site Title</a>';
return $uglinka;
}
elseif(user_group_can('10')) {
$uglinkb = '<a href="http://domain.com">Site Title</a>';
return $uglinkb;
}
else
echo "Bummer!";
}
When I ran the filter I funnily enough saw nothing except for the site title. I was logged on as administrator and I normally will see all.

Hi Jasper,
Did you see, in the query the $user_ID cannot be set without the user got logged in. So you cannot get any output for the function is_usergroup_can($groupid) without log in.
The usergroup of Role scoper is working on the basis of user id. Without user id you cannot differentiate user groups.

I see Kannan C. Well, what other options are there to filter the title on every page based on user group? The initial function works great with widget logic. I thought I could use a filter to replace the site title by one depending on what user is logged on connected to what user group. Each user group will have to have a different site title. Now a single is loaded from settings > site title. So I thought let's filter the database data grabbed before it is displayed on the browser screen. Really new to hooks and filters and still a juniot programmer for backend stuff so please help me out here.
Kannan C comments:
Again, the function can work 100% for logged in users. You can show different titles for different user groups only where a user is logged in. Then only the function can get the user id of the logged in user.
i found you missed the global variable in the above function.
function title_for_group_nine (){
$wpdb;
//your other stuff
}
this will work for logged in users.
Kannan C comments:
oh i apologize, you have the sql query on other function. So $wpdb will make no difference there.

Kannan C comments:
can you clear me one thing? are you looking for Title to show for logged in users or without login?
rhand comments:
The website is private so only registered users see content
For all logged in users under group a I need title a, under group b I need title be, and so on. For that I thought a filter using one of [[LINK href="http://dev.studiopress.com/hook-reference"]]Genesis' hooks[[/LINK]] that deals with the site title inside each page. Now only one title is loaded from the backend for all logged in users...
rhand comments:
Perhaps one of these filters should be used:
<blockquote>Header Section Filters
genesis_seo_title
Default value: $title, $inside, $wrap
Applied to the output of the genesis_seo_site_title function which depending on the SEO option set by the user will either wrap the title in <h1> or <p> tags.
genesis_seo_description
Default value: $description, $inside, $wrap
Applied to the output of the genesis_seo_site_description function which depending on the SEO option set by the user will either wrap the description in <h1> or <p> tags.
genesis_pre_load_favicon
Default value: false
genesis_header_scripts
Default value: genesis_get_option('header_scripts')
Applied to the output of the header scripts.
</blockquote>
Still reading and trying stuff..
Kannan C comments:
i don't how genesis framework works. but upon seeing the code, let's try this way
find
add_action( 'genesis_title', 'wp_title' );
to
add_action( 'genesis_title', 'title_for_group_nine ' );
no need for add_filter. this is a quick fix but you may loose genesis title settings
rhand comments:
add_action ('genesis_title', 'title_for_group_nine');

}
elseif(user_group_can('10')) {
$uglinkb = 'a href="http://domain.com">Title</a>';
return $uglinkb;

caused:
<blockquote>Fatal error: Call to undefined function user_group_can() in /home/user/domain.com/studentzone/wp-content/themes/enterprise/functions.php on line 99</blockquote>
which has if(user_group_can('9')) {
$uglinka = '<a href="http://domain.com">Title</a>';
I guess we need to make that function global first?

you have typo in the function name

are you sure you have the function is_user_group_can() in the functions.php file?
it is hard for me to figure out the error without checking the theme files..

Man! again you made a typo, replace this with yours

Sorry about that. I guess I will have to give this a break tonight. Will try once more..

Thanks for all the work so far. Code now loads without errors. But when I log in using one of the two users belonging to group 9 I still see the same title and not the new one. Code used at the moment:
/* Different Titles based on user group */
function title_for_group_nine (){
global $wpdb;
// print site_title of choice
if(is_usergroup_can('9')) {
$uglinka = '<a href="http://domain.com">Title 9</a>';
echo $uglinka;
}
elseif(is_usergroup_can('10')) {
$uglinkb = 'a href="http://domain.com">Title 10</a>';
return $uglinkb;
}
else
echo "Bummer!";

Check that user also belongs to other group. echo the result of all your if conditions.

/* Different Titles based on user group */
add_action( 'genesis_seo_title', 'new_title_per_group');

$uglinka = '<h1 id="title"><a href="http://domain.com">Title 9</a></h1>';

Works. Just need to rework all so the same style and HTML is applied as before. All good now. Thanks for hanging in there with me!
