Re: DB interface problem

Hi Giff, No worries - I know the feeling well! At first glance this looks OK, however I notice that there is no "res" property defined in the STH class, like there is session and query. $this->res on line 202 is what's causing the issue - PHP is saying it's not a valid PostgreSQL result resource, so if you trace back to where that comes from, you get to line 175: $this->res = @pg_execute($this->session, $query); PHP is therefore trying to assign a query result to a property that doesn't exist. I would have expected PHP to throw an error at this but it may have been obscured with your logging settings, I'm not sure. Try adding "public $res;" after line 85 and see what you get. You could also add "var_dump($this->res);" between lines 175 and 176 which should tell you what PHP thinks "$this->res" is. And lastly, you could get a back-trace of the rows() method call to see if it's being called before $this->res has been assigned - just add the line "var_dump(debug_backtrace());" between lines 201 and 202. Hope this gives you a starting pointer! Regards, Andy On 27 October2009, at 19:36, Giff Hammar wrote:

Andy, Sometimes I'm too fast for my own good. I added .txt to the file and it should be visible as http://www.sv-phoenix.com/dbi_pgsql.txt. Just appending the .txt didn't work. Thanks for taking a look! Giff On Tue, 2009-10-27 at 17:49 +0000, Andy Shellam (Mailing Lists) wrote:

Hi Giff, I want to have a look at this for you, but you'll need to put the file on your server as plain-text because your server is parsing the PHP code and only sending us the output, not the source code. Append *.txt to your file on the server and we should be able to see it better! Andy On 27 October2009, at 12:48, Giff Hammar wrote:

I started having trouble with a DBI interface to my PostgreSQL database after I built a new Ubuntu machine. The Postgres version is 8.3 and the DBI was written several years ago (by someone else). I'm using PHP version 5.2.6-3ubuntu4.2 with apache2. The problem is that I get the error: Warning: pg_num_rows(): supplied argument is not a valid PostgreSQL result resource in /var/www/lib/dbi_pgsql.php on line 202 I don't know what to check next to figure out why this is happening. Here is what I have done so far: - Updated the old PHP commands in the dbi file to reflect new ones var -> public pg_numrows -> pg_num_rows pg_cmdtuples -> pg_affected_rows pg_exec -> pg_execute - Connected to the database as the same user by using straight PHP calls vs the DBI. It worked fine. - Connected to the database via psql and that worked fine, too. There is something with the DBI class that is not right, but I am a novice with objects and classes, so I can't pin it down. The whole file is here: http://www.sv-phoenix.com/dbi_pgsql.php - it's 205 lines so I didn't want to put the whole thing in this post. If anyone can take a look at it and let me know what to check next, I would really appreciate it.
