Monorder_XH facilitates placing order or reservation forms for single items resp. events (hence the name which is a synaeresis of "mono" and "order") on your website. Ordering resp. booking takes in account the number of items on stock resp. the free places, so overbooking is not possible.
The forms have to be created with Advancedform_XH, and it is possible to use a single form for multiple sales items resp. events. However, it is only possible to offer one form for a particular item resp. event on each page, so if you have more demanding needs use a shopping resp. a booking system.
Besides its actual use, Monorder_XH serves to demonstrate the possibilities and limitations of using Advancedform_XH's hook system for custom plugins.
The plugin requires an UTF-8 encoded CMSimple_XH installation, PHP ≥ 5.1 and Advancedform_XH. It is released under GPLv3.
