I'd like to check a table to retrieve rows for which one field equals

$product = $row ['selection'];

$fields = substr($fields,'',-1);

This ...
$db_connect->fetch_array($sql_result);
$store_result = $db_connect->query("select * from $sql_usertable WHERE
(($sql_usertable.product1 = '($fields)')||( $sql_usertable.product2 =
'($fields)')||($sql_usertable.product3 = '($fields)')) order by id desc
limit $entry, $entries_per_page");
doesn't work. It selects nothing (obviously because no single field
equals
' (Prod1, Prod2, Prod3) '). But it's the idea. Can I change the:
= '($fields)'
syntax I'm trying?
The actual select checks more fields for this or that and gets more
complicated so I'd like to keep this as simple
as possible. I would like to do this without UNIONS (in one pass) if
possible (my
dbsql.php doesn't seem to go beyond regular query).
Try "in":
where productx in (Prod1, Prod2, Prod3)
THANKS. You saved me another day of frustration trying UNION! :-)
In addition your answer also got me here:
http://dev.mysql.com/doc/refman/4.1/en/comparison-operators.html
Except when $fields = '' (blank) >>> MySql error. Can put in if but leaves
an undefined resource (warning). Any way to initialize a resourse?
($store_result = $db_connect->query)?
