Basically I want to check to see if $fileDir is already in my database. I
do this as:
$result = mysql_query("SELECT fileDir FROM shoots WHERE
(fileDir='$fileDir')");
How do I check the result? I normally use
mysql_result($result, $row, $field)
to read my result, but if I try that I get an error:
if(mysql_result($result, $row, $field))
gives me:
Warning: Unable to jump to row 0 on MySQL result index 3
cheers,
