mysql_select_db("test") or die(mysql_error());

$queryc = "INSERT INTO `table` (data17)values ('".addslashes($test)."')";
mysql_query($queryc) or die(mysql_error());

Answer 1

for the database connection, it should be:

 $conn = mysqli_connect('localhost', 'test', 'test') or die(mysqli_error($conn));

for the query, it should be:

mysqli_query($conn, $queryc) or die(mysqli_error($conn);

remember, the mysqli_query's arguments are database connection, query also, it would be better if the query ($queryc) was:

$queryc = "INSERT INTO `table` (data17)values mysqli_real_escape_string($test))";
