Add page to Joomla Component to assign bib numbers

We have a website that is using the Joomla component Event Booking to sign up users for events. These events are for races and for each person we assign them a 'bib' number, to keep track of the racers. Different races may have different numbers, for example one race may only use numbers 1000 to 9999, or another race may only use numbers 200 to 400. We need to add a new page to the admin section of this component where the admin can assign bib numbers to all registrants for an event. This page will need a little bit of javascript and ajax to populate some of the form fields. The specifics are below: - Add a new menu item under 'Components > Event Booking' called 'Assign Bib Numbers' - This page will have the following form: - Choose Event (drop down) - choose from all the available events - Choose Sub Event (drop down) - dynamically populated list of sub events based on the choice of 'Event' field - Bib Range (two text fields) - enters a range of two numbers, ie. '100' to '200' - Preview button - Delete button This is how the form works: - It will select all registrants for the selected Event/Sub Event. It will cycle through that list and assign each person a number, starting at the beginning range and stopping at the end range. If there are more users than numbers then it will stop and the remaining users don't get a number. If someone already has a number then it will skip that person. - When the admin clicks on 'Preview' it will show a preview table of what the bib assignments will be. After the table will be a save button to save the bib assignments. When the admin clicks 'save' the numbers will be saved to the database in the registrants table. - There are some entries in the registration table that are only used for billing, these users should not be assigned numbers. - The delete button will delete all user numbers for the selected Event/Sub Event with numbers in the range. ie. Event = New Run Sub Event = 5k Run Range = '100' to '200' - This would delete all numbers between '100-200' for the event 'New Run', sub event '5k Run' Let me know if there are any questions about the project.
