$user_date = ISSET($_POST['input_date']);

$query1=mysql_query("SELECT START_TIME,END_TIME FROM dummy where MDATE='$user_date'")

Answer 1

isset() returns a boolean value if the variable has been set, not the value of the variable itself. You need something like:

$user_date = isset($_POST['input_date']) ? mysql_real_escape_string($_POST['input_date']) : '';

The above is a ternary operation. If the input value has been set, it is escaped and stored into $user_date. Otherwise, an empty string is returned. You would need to decide what action to take when it isn’t set, the part after :. For example, you could return a default date instead:

$user_date = isset($_POST['input_date']) ? mysql_real_escape_string($_POST['input_date']) : '2012-03-18';
