displaying cart contents and then updating

[aussieguy]

Gday people

I need to find a stand alone script that will work the same as a display contents of a shopping cart.

I have been able to

Put data into a table using session ID as the user

Retrieve the data from the table using the session ID in the select query

But I have no idea on how to:

The shopper can delete a record by inserting a zero into the values (just to make matters worse there are TWO values Adult and Child that must be zero in order to delete the record)

Or the shopper can modify the record by putting a different number into the textbox

then pressing one submit button to modify/delete the records

Any help in where to find examples--- or code snippets will be greatly appreciated.

Thanks in advance

hi,

why do you insert the records if they are NULL or 0?

do something like this

if ($form_adult == NULL || $form_adult == 0)
{
	// don't insert data
} else {
	//insert data
}


if ($form_child == NULL || $form_child == 0)
{
	// don't insert data
} else {
	//insert data
}

hope this helps,
