}
can you tell me whats wrong? The if statement with the query to database wont execute and if i remove the if statement of sched exist the query will execute. i dont know whats the problem. Help me please
empty($_POST) is never false. better ask for if ( count($_POST) == 0)
mysql_result(result,0) returns the value of the first column of the first row of the result. This will probably not be 1 unless it happens that the first row is an ID column and the first result happens to have an ID of 1. You really should be doing something like:
$result = mysql_query(/*your query*/);
if ($result) return true;
else return false;
