How to Regenerate user_privileges Files Easily in vTiger

In vTiger CRM, the user_privileges files store the access permissions for each user. If these files become corrupted or you need to regenerate user_privileges Files (for example, after updating roles or profiles), you can do so through the following methods:

1. Using vTiger’s Recalculate Permissions Option

The simplest way to regenerate user_privileges files is through the Recalculate Permissions option in the UI.

Steps:

1. Go to CRM Settings:

• From the vTiger dashboard, click on the gear icon in the top-right corner to access CRM Settings.

2. Navigate to User Management:

• Under the Users & Access Control section, click on Users.

3. Recalculate Permissions:

• Select the user whose privileges need to be recalculated.
• In the user detail view, you’ll see an option to Recalculate Permissions (typically near the bottom of the page).
• Click on this option to regenerate the privileges file for the user.

2. Manually Regenerate the Privileges Files

If the above method doesn’t work or you want to regenerate the files for all users, you can do it programmatically.

Steps:

1. Access vTiger Directory:

• Navigate to your vTiger CRM installation directory on the server, usually under public_html, or wherever the CRM files are stored.

2. Run the PHP Script to Regenerate Files:
You can use vTiger’s built-in function to regenerate user_privileges files for all users.

• Open the file includes/utils/UserInfoUtil.php.
• Find the function createUserPrivilegesfile($userId). This function is responsible for generating the user privileges file for a specific user. To regenerate the files for all users, you can write a small script to loop through the users and regenerate their privileges.

   include_once('includes/utils/UserInfoUtil.php');
   global $adb;

   $result = $adb->pquery("SELECT id FROM vtiger_users WHERE status = ?", array('Active'));
   while ($row = $adb->fetch_array($result)) {
       $userId = $row['id'];
       createUserPrivilegesfile($userId);  // Regenerate privileges for this user
       echo "Regenerated user_privileges for user: " . $userId . "\n";
   }

• Save this script as regenerate_privileges.php and upload it to the root directory of your vTiger installation.

3. Run the Script:

• Open the script in your browser by visiting http://yourdomain.com/vtigercrm/regenerate_privileges.php.
• The script will loop through all active users and regenerate the user_privileges files.

4. Delete the Script:
After successfully regenerating the files, delete the script from the server for security reasons.

3. Regenerating for Specific Users via Code

If you want to regenerate the user_privileges files for a specific user via code:

1. Log in to your server.
2. Execute the following PHP code in the vTiger CRM environment:

   include_once('includes/utils/UserInfoUtil.php');
   $userId = 1; // Replace with the ID of the user you want to regenerate
   createUserPrivilegesfile($userId);

This will force the system to recreate the user_privileges file for that specific user.

4. Regenerating via SQL (For Advanced Users)

If the above methods fail and you’re familiar with SQL, you can delete specific entries related to user privileges and let the system regenerate them the next time the user logs in.

For example:

DELETE FROM vtiger_user2role WHERE userid = '1';  // Replace '1' with the user's ID.

Make sure you have a backup before performing SQL operations directly.

Conclusion

In the case of vTiger CRM, the user_privileges files store the access permissions for every single user. If all these files become automatically ruined or you want to regenerate user_privileges files (for instance, after updating profiles or roles), you can do it with the help of the above-mentioned methods by having the best Vtiger hosting solutions.
