Am retrieveing an "available" ipaddress from a table, then later trying to
perform an update to "assign" the address to an id. The update produces no
error, but doesn't update either. Must be overlooking something but can't place
a finger on it.
Table "host_ipaddress"
Attribute | Type | Modifier
-----------+---------+----------
server | text | not null
type | text |
hostnum | integer | not null
address | text |
Index: host_ipaddress_pkey
<?PHP
# Variables
$database = ***pg_connect statement***
$hostnum=2; # client reference number
$primipaddr=AssignPrivateIP($hostnum,'web'); #function returns IP address
# Function
function AssignPrivateIP($hostnumber,$server) {
global $database;
$query = "SELECT address FROM host_ipaddress WHERE server='$server' AND
type='private' AND hostnum=0 LIMIT 1";
$result = pg_exec($database,$query);
if(pg_numrows($result)==0) {
$return=0;
} else {
$row = pg_fetch_array($result,0);
$return=$row[0];
}
return $return;
}
# Queries
# following does not work, the hostnum in the database table stays at 0
$query="UPDATE host_ipaddress SET hostnum=$hostnum WHERE address='$primipaddr'";
# the following updates all records for the server/of type priv to 2
# **EXCEPT** the IP address we retrieved from the function (which we want to
update)
$query="UPDATE host_ipaddress SET hostnum=2 WHERE server='web' AND type='priv'";
...appropriate exec etc...
?>
