Answer 1

you need to fetch the data from as mysql_query() returns only link identifier, from manual:

For SELECT, SHOW, DESCRIBE, EXPLAIN and other statements returning
resultset, mysql_query() returns a resource on success, or FALSE on
error.

$fetch_date = mysql_query("SELECT date FROM sondaje WHERE id = '$id'") 
             or die("Error! DataBase Name Incorrect!");

$date = mysql_fetch_assoc($fetch_date);
