Handling forms with repeating fields


Inf51

Recommended Posts

I'm working on a shopping cart type site and I have a page which displays the contents of the cart (stored in a database).

 

I'd like the user to be able to tick a 'delete' checkbox or change the quantity on a record and click an update button to either delete or update that item's record.

 

I'm happy with how I can do this with a single item or having a repeating region in my code where each item is within its own <form></form> tag and has its own submit button but I would like to have just one form and one submit button but containing all the items in the cart.

 

I guess I may need to have my code dynamically name the form fields so that for example the product ID for item 1 can be differentiated from the ID for item 2, 3, 4 etc.

 

I'm happy with the SQL involved but I'm just not sure how I process a form with multiple records in it in PHP - do I need to count the number of records in a form and loop though them somehow?
