Member Group Sponsorship
By Paul

You can use member group sponsorship to let people purchase special powers (which might include the ability to add more listings than regular members) or let them have all their listings promoted to a special type at once for extra recognition.

First, fill out the general settings at the top of Admin Panel -> Settings -> Sponsorship. You can use any of the three supported payment processors -- PayPal, 2checkout and nochex -- or you can leave all three of those fields blank and process payments manually.

Click the "Add Usergroup Sponsorship Level" link to add a level. Follow the instructions on screen. Important Note: the item numbers can be any unique numbers for PayPal or nochex, but for 2checkout the item number must be the same number as a corresponding product you set up through the 2checkout interface that has your desired price and an approved URL of WhereverYouInstalledWSN/2checkout.php .

If you want to require all registrations from non-admins to be sponsored, just create a sponsorship level which promotes to "Members" (you can have them revert to guests or to another usergroup you set up for expired members with guest-like permissions).

After you've set up a sponsorship level you'll see the levels you've created listed on the sponsorship settings page for you to edit.

You can customize the payment buttons and the rest of the payments page at Admin Panel -> Templates -> Manage Templates -> "Sponsor Purchase - Usergroup". You can set the price in the paypal button to whatever value you want, and that amount will be credited to the account on purchase, and deducted at the rate specified by your sponsorship settings. In other words, feel free to have people buy in $100 quantities even if you want to deduct at $1/day. Note that this won't work for 2checkout, which only accepts product numbers.

You'll find a link (to membersponsor.php) asking your members to sponsor has appeared at the bottom of pages. This is in your wrapper template.

Notes

To test paypal using paypal's sandbox, you need to set the $paypalsandbox tweak -- and remove it before going live.
