Passing variables without a form using url

manpreet Best Answer 3 years ago

I have been trying to find information on passing variables without a form using url, but I can't seem to find anythig that pertains to my situation. Basically I need to have a page that is hierachical in the sense that you can click one course out of a list, that brings you to a list of sections, and you can click on a section which will bring to a page with the correct information for that one section. I was taught for this situation to use $_SESSION and then to include the variables in the url. My problem is that everytime I click on a course or a section, the information for every single course or section that is a query match is displaying rather than just the information for that one course or section. This is what I have for each of the pages in hierarchical order (not including the connect portion of the code which works fine anyways). I know this is a ton of code, and a complete mess. I will keep searching out information, and many many thanks in advance for any help.

List of Courses

  session_start(); 
$section = $_SESSION['section_id'];
$user_fname = $_SESSION['user_fname'];
$user_lname = $_SESSION['user_lname'];





     $query = "SELECT DISTINCT course_t.course_id, course_name, user_fname, user_lname, section_t.section_id   
               FROM   course_t, authorized_user_t, section_t, teaching_history_t
               WHERE authorized_user_t.authorized_user_id = teaching_history_t.instructor_id
                AND teaching_history_t.section_id = section_t.section_id
                AND section_t.course_id = course_t.course_id";





 $result = @mysql_query($query);



 while ($line1 = mysql_fetch_array($result, MYSQL_ASSOC)) {


   echo '
.$line1['section_id'].'&user_fname='.$line1['user_fname'].'&user_lname='.$line1['user_lname'].'">' .$line1['course_id'].':'.$line1['course_name']. '

'; 




     }

List of Sections (it is supposed to list a single intructor and then each of the sections they teach under their name)
