Posted 6 years ago #just the name? Like it display something like: "Welcome user!"?
there is a script for that:
<?php global $user_nickname;
get_currentuserinfo();
if ( $user_nickname<> "" ) { ?>
<?php echo $user_nickname ?>
<?php } else { ?>
Welcome Guest<?php } ?> -
No doubt there is a better way then doing it like this but...
function dirty_get_role($id){
$role = explode('"',$wpdb->get_var("SELECT meta_value FROM wp_usermeta WHERE meta_key = 'wp_capabilities' and user_id = '$id'"));
return $role[1];
}
This is a VERY, dirty way of doing it!

Posted 6 years ago #I tried to put the function directly in my sidbar for a test but don't work... i tryied this:
<?php
global $userdata;
get_currentuserinfo();
$role = explode('"',$wpdb->get_var("SELECT meta_value FROM wp_usermeta WHERE meta_key = 'wp_capabilities' and user_id = '$userdata->ID'"));
echo $role[1];
?>and work very well... but i use widgets, and when i putted in my function.php (or use phpexec widget), all under the widget in the home page disappear... where i'm wrong?? :(
This is the code i used for functions.php:
function widget_user_role() {
global $userdata;
get_currentuserinfo();
$role = explode('"',$wpdb->get_var("SELECT meta_value FROM wp_usermeta WHERE meta_key = 'wp_capabilities' and user_id = '$userdata->ID'"));
echo $role[1];
}
if ( function_exists('register_sidebar_widget') )
register_sidebar_widget(__('User Role'), 'widget_user_role'); -
Im not too sure how to help you here, ive not really looked at widgets myself.
Do you get a error at all on the sidebar? or is it just a case of nothing else will display after the widget_user_role()prints out?
Sorry i should have also mentioned above that you would need to global $userdata if you hadnt already got hold of the userid.

Posted 6 years ago #I don't get an error... nothing will display after the function call... but if i try the same code outside of a function it worck perfectly.
I know about the $userdata variable but, the function you suggest me don't work if i put it in a template file... i used the code without the function (as I mentioned above) and the role is shown correctly.
in practice:
1)the code only work outside a function in the template (i will try to put the function in other file and the call in the template or the widget)
2)the code don't work in a widget -
The function i wrote only returns the role value, so you would need to echo dirty_get_role(); for my one to print.
Try putting your widget_user_role() as the last widget on your sidebar, if it then displays all the other widgets you know there summat wrong with the widget_user_role() function its self.
Also if its working when not being used as a widget it would seem to suggest you have not written the function correctly, i belive theres a certain way you are supose to write you widgets.
But as i said before, ive not really bothered with widgets so cant really help much on that side of things!

Posted 6 years ago #Hi phunky... tnx for your reply. I solved with this your function mod:
<?php function get_role_from_db() {
global $wpdb, $userdata;
get_currentuserinfo();
$ruoloutente = explode('"',$wpdb->get_var("SELECT meta_value FROM wp_usermeta WHERE meta_key = 'wp_capabilities' and user_id = '$userdata->ID'"));
echo $ruoloutente[1];
} ?>
I forgot the "global $wpdb" variabile... :P
I can call it without an echo, and work perfectly if I put it in the sidebar, in a plugin, or in a widget in functions.php of my template. Only don't work if i put the entire function in a phpexec widget (it's a text widget that can eval() php code), but i think it's a bug that i must discuss with the widget's author...In any way, if there is some less dirty function that can do this, i appreciate a little help... thanks to all replyers

Hi Rediect1, glad you got it sorted!
Im almost certain there is a built in function to get the user role but ive totaly forgot what it is.
Tbh i tend to re-create the get_currentuserinfo() function myself with one that gathers all the user detail including wp_usermeta and the user role.
Anyway im glad you got it to work :)
