I'm taking a guess, but it sounds like you want to insert a row with a URL
plus the ID of the record the URL is stored under? If so, there are a couple
ways you can accomplish this. Take a look at create sequence in the docs for
an explanation.
One method is not to create the table with a serial ID. Create it with an
int and use a manual sequence. That way you get the ID value before
inserting the row. A bit more work to set up the table, but less work later.
If you want to stick with the serial type, you'll have to use pg_getlastoid
and look up the ID of that row. Less work setting up the table, but more
work in your scripts. Here's an example
$check=pg_Exec($connection,"create table mytable(my_id serial primary
key,my_url char(50);");
$check=pg_Exec($connection,"INSERT INTO mytable(my_url) values(null);");
$oid=pg_GetLastOid($check);
$idrow=pg_Exec($connection,"SELECT my_id FROM mytable WHERE oid='$oid';");
$id=pg_Result($idrow,0,'my_id');
$url=$url.$id;
$check=pg_Exec($connection,"UPDATE mytable SET my_url='$url' WHERE
my_id='$id';");
Of course, you could also use WHERE oid='$oid' instead. Just remember, you
can't count on an OID remaining the same all the time. Don't try to use OIDs
like a primary key. Every time postgres is started the oid could point to a
different object or even no object at all. Quite safe to use in the above
manner though.
