Tailor your query to the request of your user(s). I.e. if only one
parameter was passed from the form only match against one field.
E.g.:
$sql = "SELECT ID, publication,run_date,left(ad_copy,40) as
Advertisement FROM classifieds WHERE MATCH ";
if ($param1)
$sql .= "(ad_copy) against ('$param1')";
if ($param1 && $param2)
$sql .= " AND MATCH ";
if ($param2)
$sql .= "(long_group) against ('$param2')";
/* query */

Subject: Trapping for no user input in a query
Hello all
I am trying to query two columns in mysql which have fulltext indexes
using the following:
SELECT ID,publication,run_date,left(ad_copy,40) as Advertisement FROM
classifieds WHERE MATCH (long_group) against ('\"$param2\"') AND MATCH
(ad_copy) against ('\"$param1\"')
As you can probably guess, the $params are coming from a form via php.
The above query works fine when the user submits both parameters but I
can't work out how to trap for the user only entering a single parameter
(which causes the query to always return an empty set)?
Cheers and thanks
kim
