Check Box Validating.. and display values

thara

Hello..

I have Two HTML form and one is a Check boxes form that enable users to select their category. Then I need to display second form according to the categories they selected in first form. I use this code in first form to validate form submission..

  if ( isset( $_POST['category']) && sizeof( $_POST['category']) <= 3) {

     $category = $_POST['category'];         

  } else {

     $errors[] = 'Please select atleast 1, not more than 3 categories';
  }

If errors array is empty I did this..

  if ( empty( $errors )) {  // If everything's OK      

     $_SESSION = $category;

     $url = 'http://localhost/lanka_institute/tutorsignup/select_subjects.php? // Define the URL.
     ob_end_clean(); // Delete the buffer.
     header("Location: $url");
     exit(); // Quit the script.   

  }

Can I know and is this correct? I display category list from mysql category table, it has category name and category id

this is my html part from first page

  echo '<td width="50%"><input type="checkbox" name="category[]"  vlaue="' . $info['category_id'] . '" />&nbsp;&nbsp;' . $info['category_name'] . '</td>';

any help appreciated.

Thanks in advance..

Its still problem.. my first form is 'sign_up.php' and second is select_subject.php'. sign_up.php page has more categories and users can select up to 3 more categories there. So. after selecting and user click the continue bottom, page want to go to second form page its select_subject.php page. In there, i want to display the categories which user selected from sign_up.php page and also its provide to select subjects according to the categories they have selected.

my problem is how can I check what are the categories user have selected and how they display in my second page.

category come to first page from my category table. It has category_id and category_name columns.

thanks for any help..

You should be getting the selected items in $_SESSION['category'] on select_subject.php. However the ideal approach would be, build a html to post directly to select_subject.php instead of storing it in session and redirect.

<form method="post" action="select_subject.php"> <your select boxes> </form>

I did it so.. then my error message not working. page directly going to select_subject.php page. I have limited to 3 categories which users can select in first page. If it is not so I need to display an error message in sign_up.php page.

Ok, in your way, what is the value of $_SESSION['category'] in select_subject.php ?
