I am having trouble with a db query that was working not too long
ago. I did upgrade from php4 to php5 and wonder if there are some
differences that could explain my issue. Below is the code where I
suspect things are breaking down.
// build sql query from form values
$select_query = "select * from grid_cell where township = $township
and range = $range and rdir_shortname = '$rdir_shortname'
and section = $section and forty_name = '$forty_name'";
//echo $select_query; // use for debugging sql query
// retrieve the query info from postgresql
//this returns a resource, so put the resource into a variable
$result = pg_query($select_query);
//echo $result; // use for debugging sql query
// process results. First argument pg_result is the returned result
set ($grid_cell),
// second argument is the row offset, and the third argument is the
column offset.
$forty_grid = pg_result($result, 0, 0);
//echo $forty_grid; // use for debugging sql query
If I uncomment echo $select_query, the scrip prints the proper query
like this:
select * from grid_cell where township = 67 and range = 1 and
rdir_shortname = 'W' and section = 1 and forty_name = 'NWNW'
However, if I uncomment echo $result, the script prints:
Resource id #2
and also the error:
Unable to jump to row 0 on PostgreSQL result index 2
I think that the variable $result is getting the result from pg_query
and subsequently $forty_grid is not receiving what it expects either.
Does anyone see what I'm not doing right here?
Thanks,
