I need to grant users a specific role (Editor, Administrator, etc.) along with all its capabilities on the fly in Wordpress, but I don't want to update their role in the database (so that the next time they come back, they will have their original role). How can I go about doing this?
Here's what I ended up doing:
add_filter( 'user_has_cap', 'override_caps' );
function override_caps($allcaps){
if( ... ){ // When to override caps
$role_name = 'administrator';
$role = get_role($role_name); // Get the role object by role name
$allcaps = $role->capabilities; // Get the capabilities for the role
$allcaps[$role_name] = true; // Add role name to capabilities
}
return $allcaps;
}

I want that user having special role assigned can buy product from my store without pay. I searched around and found Role based shipping/payment plugin. This plugin works fine for other user role but it do not allow user having special role to place order.
Is there a way to allow only users with special role to place order without any payment and shipping method?
Thanks in advance.
You can modify price by this function.Please take backup and perform modifications.
public function get_db_price($id){
$user = wp_get_current_user();
if($user->roles[0] == "VIP"){
return 0;
}
else{
self::$db_prices = get_post_meta($id,'_role_based_price',true );
if(is_array(self::$db_prices)){
return self::$db_prices;
}
}
return false;
}
Have some problem... Maybe somebody knows how to set role for current user in Wordpress.
I tried this code
function uproles()
{
$current_user = wp_get_current_user();
$roles = $current_user->roles;
if (current_user_can('access1') == true) {$role = "access2";}
do_action('set_user_role', $current_user->ID, $role, $roles );
}
But it seems it does not work:(
From admin panel Just goto Users > your user and set the user role to what ever you want. If you want to set a default role to all new users, goto Settings>writing there is a field where you can set the default role.
Iam working with buddypress,
I have a two user roles,
1-student
2-faculty
and i have set default user role as subscriber.
when user registers and activates account by clicking on link sent through mail.User role changes to default(subscriber).
Any idea what is the issue? Below is the code assigning role to user on sign up.
add_action('bp_core_signup_user', 'ad_user_signup_usermeta', 10, 5);
function ad_user_signup_usermeta($user_id, $user_login, $user_password, $user_email, $usermeta) {
if(isset($_POST['signup_membership']) && !empty($_POST['signup_membership']))
update_user_meta($user_id, 'membership', $_POST['signup_membership']);
$userdata = array();
$userdata['ID'] = $user_id;
if(!empty($_POST['signup_usertype'])) {
if($_POST['signup_usertype'] == 'student') {
$userdata['role'] = 'student';
}
if($_POST['signup_usertype'] == 'instructor') {
$userdata['role'] = 'instructor';
}
}
if ($userdata['role']){
wp_update_user($userdata);
}
}
Upon activation, BuddyPress (at least version 2.0.2) updates the user's role to the default role.

You can comment out that line, or write some code to work around it. I'm using "WP Roles At Registration" and ran across the same problem. I ended up adding a filter on bp_core_signup_user to save the original role but you'll want to add something like this to your ad_user_signup_usermeta:
update_user_meta($user_id, 'temp_role', $role_name)
then reset it back in a filter for bp_core_activated_user
public function after_bp_activated_user($user_id, $key, $user) {
$user = get_userdata($user_id);
$role = get_user_meta($user_id, 'temp_role');
if ($role) {
$user->set_role($role[0]);
}
}
add_filter('bp_core_activated_user', array($this, 'after_bp_activated_user'), 30, 3);
I'm using Formidable forms in Wordpress and have a form that registers users. I can use a radio button in the registration form to determine what their role will be. I have a hook for that. What I need, however, is a hook that will change the user role based on radio selection on form entry UPDATE. My current code only works on entry creation. Here is the code that assigns roles on registration:
add_filter('frmreg_new_role', 'frmreg_new_role', 10, 2);
function frmreg_new_role($role, $atts){
extract($atts);
if($form->id == 8){
if($_POST['item_meta'][280] == 'Job Applicant')
$role = 'applicant';
}
return $role;
}
"8" is the id of the form itself. "280" is the id of the radio button field where "Job Applicant" is one of the values. And "applicant" is one of our site's user roles.
I need an adaptation of this that will change the role after the entry has already been created, on update. The closest thing I can find is a hook that changes user role after a successful PayPal payment. I tried to combine the two but I couldn't get it to work. Here is the PayPal generated user role changer:
add_action('frm_payment_paypal_ipn', 'change_paid_user_role');
function change_paid_user_role($args){
$new_role = 'contributor'; //change this to the role paid users should have
if(!$args['pay_vars']['completed'])
return; //don't continue if the payment was not completed
if(!$args['entry']->user_id or !is_numeric($args['entry']->user_id))
return; //don't continue if not linked to a user
$user = get_userdata($args['entry']->user_id);
if(!$user)
return; //don't continue if user doesn't exist
$updated_user = (array)$user;
// Get the highest/primary role for this user
$user_roles = $user->roles;
$user_role = array_shift($user_roles);
if ( $user_role == 'administrator' )
return; //make sure we don't downgrade any admins
$updated_user['role'] = $new_role;
wp_update_user($updated_user);
}
UPDATE: the action hook should probably be: frm_after_create_entry according to Formidable forums.
Many times, researching the core files is more productive than any Google or Manual. Dropping the whole plugin directory in a code editor and researching for the string frm_after_create_entry takes us to the create() method where this hook happens.
After that, there's the update() method and it provides the action hook: frm_after_update_entry.
This hook passes two parameters: $id and $new_values['form_id']. I cannot reproduce your setup, so testing the hook is up to you.
Reference: Actions and filters are NOT the same thing…
In this example:
add_action( 'frm_after_update_entry', 'change_role_to_staff', 10, 2);
function change_role_to_staff( $form_id, $values ){
var_dump($values);
die();
}
As this is an action hook, nothing has to be returned.
There's no $roles or $atts, the parameters are the form ID and Values.
What you're looking for is inside $values.
var_dump() and die() are for debugging purposes and must be removed at once after testing.
Do your wp_update_user with this values and adapting your previous code.
While a user is creating a new post, how do I determine his current role?
I'm assuming you know what hooks of Wordpress you want to use. So skipping that part, it's pretty easy to get the current role of the user
$current_user = wp_get_current_user();
if ( !($current_user instanceof WP_User) )
return;
$roles = $current_user->roles; //$roles is an array
Now, you can iterate over that array to see if the user has a particular role.
Or, you can use current_user_can to look for specific capabilities, if you just want to check whether or not a user has a specific permission versus whether or not they're in the role. For example:
if (current_user_can('delete_posts')) {
//display the delete posts button.
}
This code will help you
<?php echo array_shift(wp_get_current_user()->roles); ?>
