Well, in that case, you might be able to do something along the lines of this.
I tested this on my server:
Server version: 5.0.51a-log
MySQL client version: 5.0.51a
using phpMyAdmin - 2.11.1.2
I have modified an example from this page:
http://dev.mysql.com/doc/refman/5.0/en/user-variables.html
<?php
#
# Setup database stuff, process input, get everything ready to do the insert.
#
# Now prepare your statement
$SQL = "
SET @confirm_number=(SELECT (MAX(confirm_number)+1) FROM `contacts`);
INSERT INTO `contacts` (
`first_name`,
`last_name`,
`email`,
`phn_number`,
`address`,
`city`,
`state`,
`zip`,
`dates`,
`comments`,
`confirm_number`
) VALUES (
'{$FirstName}',
'{$LastName}',
'{$Email}',
'{$Phone}',
'{$Address}',
'{$City}',
'{$selected_state}',
'{$Zip}',
'{$newdate}',
'{$Comments}',
@confirm_number
)
SELECT @confirm_number AS confirm_number;
";
$confirm_number = NULL;
# Run it and get confirm_number to work with now.
if ( ($result = @mysql_query($SQL)) !== FALSE ) {
list($confirm_number) = mysql_fetch_row($result);
}
if ( is_null($confirm_number) ) {
echo 'Failed to get number';
}
?>
Obviously, I can't test this without your schema. So, I hope it works.
In the end, you should have a result set that gets returned that contains the
'confirm_number' of the newly created entry.
This should also, pretty much, eliminate any chance of a race condition. Since
everything is happening within mysql, it should be very hard to end up
with a condition that you start stomping on records.
Let the list know if it works for you.
