Check Box Validating..

[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'] . '" />  ' . $info['category_name'] . '</td>';

 

 

any help appreciated.

 

Thanks in advance..

Well, it seems you already know that $_POST["checkbox"] is an array of the checkboxes the user has selected, so... use that to determine what you want to show in the second form.

Can you be more specific about what you're not sure how to do?

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.
