i have the following code...


$assembly = $_POST['product_base'];
$assembly_notes = $_POST['assembly_notes'];

$db = &ADONewConnection('postgres');
$db -> Connect($db_string,$db_owner,$db_pw,$db_name);

$assembly_notes_insert_id = $db->getone("select

$sql = "INSERT INTO t_assembly_notes
(assembly_notes_id, assembly_notes,
assembly_notes_entry_date) VALUES (" .
$assembly_notes_insert_id . ", " .
$db->qstr($assembly_notes) . ", " .
$db->DBDate(time()) . ")";

$result_notes = $db->Execute($sql);

//insert ids into link table
$id = $assembly_notes_insert_id;
if (isset($_POST['product_base']) and
foreach($_POST['product_base'] as $V)
echo "Value: $V<br>\n";

$query = "INSERT INTO
t_link_product_base_assembly_notes " .
"(product_number, assembly_notes_id) " .
"VALUES (" . $db->qstr($id) . ", " . $db->qstr($V) .
$result_link = $db->Execute($query);


everything works fine except for my foreign keys.

this code checks to see whether my assembly_notes_id
is in my product table and checks whether my
product_number is in my assembly_notes table - the
opposite of what i want to happen.

my link table has its assembly_note_id referencing the
assembly_note_id in the assembly_notes table.

my link table has its product_number referencing the
product_number in the product table.

i'm at a loss b/c i don't understand this behavior.


i've created a foreign key in pgadmin 3.

i have a link table that links to product_number and
assembly notes.  the reason for the link table is so i
can allow one note to be attached to more than one

i created a foreign key in pgadmin 3 bwteen the
product_number in the link table and product_number in
my product table.

when i go to the pgadmin 3 constraints folder, open
this foreign key and click on the columns tab, it
shows conflicting information.

Local says "product_number"
Referenced says "product_number"

so far, so good.

Referencing says " dropped 1......." in the
drop down menu.  i previously had to drop my first
created column.

when i first set it up, i made sure to choose
product_number from the drop down menu, but it
defaults back to " dropped 1......."

i'm not sure if this is related to my problem, but too
much information is better than not enough
