New Features

1. User group-based discount permission control

• Added a new multi-select option in the Admin Control Panel: “User groups eligible for discounts”
• Administrators can choose one or more user groups to receive the global discount
• Supports checking both the primary user group and secondary user groups
• If no user group is selected, all users can receive the discount (same as the original behavior)

2. Smart discount display logic

• Users with permission: show the original price with strikethrough + discounted price (same as the existing behavior)
• Users without permission:
  • Resource list: only show the original price (discount is hidden)
  • Actual purchase: user pays the original price (prevents discount bypass)
  • User experience: discount information is automatically hidden to avoid confusion

3. Upgrade prompt feature

• Displays a noticeable prompt in the resource list for users without discount permission
• Prompt content: Upgrade to a premium account to get X% off purchases (see the site example for details)
• Prompt position: in the meta information row (after author, date, and category)
• Prompt style: orange text + gift icon, eye-catching but not intrusive
• Dynamic display: automatically reads the discount percentage configured in the Admin Control Panel

Use cases

• Membership tier system: provide exclusive discounts for VIP / SVIP members
• Promotional campaigns: temporarily enable discounts for specific user groups
• Points incentive: encourage users to upgrade to higher membership tiers
