Question

I’m having a problem with this piece of PHP. It’s meant to print out a table of products chosen from the last page – passed through POST with names in the format ‘quantityN’ where N is a number <150 & refers to a unique ID – primary key – in the table CSGames.

I know that the problem isn’t with my $connection, as I successfully load the list in the last page.

The error:

Warning: pg_query() [function.pg-query]: Query failed: ERROR: syntax error at or near "FROM" LINE 1: ...efnumber,name,platform,price WHERE refnumber='20' FROM CSGam... ^ in /berw/homes1/g/gij2/public_html/cs25010/basket.php on line 102

My live project can be found here – index>catalogue>basket.

Does anyone have any idea what’s wrong with my code? Thanks in advance.

SELECT refnumber, name, platform, price FROM CSGames WHERE refnumber='".$id."'

should work. SELECT statements are always structured like so:

SELECT [column names] FROM [table name] WHERE [conditions]

Your query was structured like:

SELECT [column names] WHERE [conditions] FROM [table name]
