Create Ajax + PHP
I need to create a logic for a "reservations" page. The scenario is as follows:
When opening the incident page, the client will have to fill two fields:
- date (calendar) *screenshot
- hour (combo box) *screenshot
When the client selects a date and time in which it has already been used, it should show a warning notifying you to choose a new time.
I would need some tips on how to do the ajax + php part.
Can someone help me?
