The user doesn't even have to hit back, each time the form is
submitted, the data is rearranged in opposite order.
Too keep my data together, here is what the data in the arrays looks
like:
Array
(
[0] => 01-30-2004|Wilkes-Barre|PA|Salt Lake|UT||Yes|Yes
[1] => 01-16-2004|Wilkes-Barre|PA|Salem|WA||Yes|Yes
[2] => 01-02-2004|Wilkes-Barre|PA|Denver|CO||Yes|Yes
[3] => 01-08-2004|Denver|CO|Wilkes-Barre|PA||No|No
[4] => 01-23-2004|Salem|WA|Wilkes-Barre|PA||No|No
[5] => 02-11-2004|Salt Lake|UT|Wilkes-Barre|PA||No|No
)
Then, in my script, after the new data is merged with the existing
array, I sort:
$array = $_SESSION['Air_Reservations'];
sort($array)
New output:
Array
(
[0] => 02-11-2004|Salt Lake|UT|Wilkes-Barre|PA||No|No
[1] => 01-23-2004|Salem|WA|Wilkes-Barre|PA||No|No
[2] => 01-08-2004|Denver|CO|Wilkes-Barre|PA||No|No
[3] => 01-02-2004|Wilkes-Barre|PA|Denver|CO||Yes|Yes
[4] => 01-16-2004|Wilkes-Barre|PA|Salem|WA||Yes|Yes
[5] => 01-30-2004|Wilkes-Barre|PA|Salt Lake|UT||Yes|Yes
)
See now? I didn't add a new record this time, but it happens with our
without adding anything new. Each time the array is sorted, this
happens.
Thanks,
Jake
