Please i need a little php help. i have a shopping site, kinda like a online movie ticket booking system. The problem i have is when a user is trying to book for a ticket he goes through the various steps. User first buys the ticket then u chooses the number of seats to book for and continues to the next step. The main issue is that after choosing the number of seats to book for and clicks on continue and then clicks on the browser back button, one more seat adds up to the previous booked seats. Please help me to still maintain the number of booked seats is browser back button is clicked. Thanks...
