I want to pass an array from one page to excell generation page. I tried to pass through session($_SESSION['sql'] = $var). But value is not set.
The array is actually $result = mysql_query($query);
did you call session_start() at the beginning of your scripts? Is the query executed without an error? Are there any rows returned?
Start with something simple and see if it works:
Page 1: session_start();
query database...
print_r() the result
store the result in session variable
link to Page 2
Page 2:
session_start();
print_r the session variable
