Answer 1

You're missing a quote on this line:
$check = mysql_query("SELECT * FROM basvurular WHERE memb_id='$memb_id'");
Also, to check whether a SELECT query returned any rows, you should use mysql_num_rows(), not mysql_affected_rows() -- the latter is only for queries that modify tables.
You should also check that the query is successful:
$check = mysql_query("SELECT * FROM basvurular WHERE memb_id='$memb_id")
or die(mysql_error());
