If Else Statement

[Given2Fly]

Hi, I need help creating an if else statement for shoppingcart.php. Basically, if someone adds product 29 to their cart, the page sees that and redirects them to a page that will show them the course materials they will need to go along with that.

 

Can anyone help?

Hi,

 

I can't remember what the variable name is in osC for product ID (or it's maybe from an array ?? ), anyway let's assume it is called 'product_id' for this exercise, the code would be something like:

 

<?PHP
if(product_id == '29')  {
header("Location: http://www.example.com/course_materials.php"); /* Redirect browser */
}
?>

 

Read up on the header() function here at PHP.NET

In /catalog/includes/application_top.php starting at line 356 you need to change 2 case statements.

 

Original code

      // customer adds a product from the products page
     case 'add_product' :    if (isset($HTTP_POST_VARS['products_id']) && is_numeric($HTTP_POST_VARS['products_id'])) {
                               $cart->add_cart($HTTP_POST_VARS['products_id'], $cart->get_quantity(tep_get_uprid($HTTP_POST_VARS['products_id'], $HTTP_POST_VARS['id']))+1, $HTTP_POST_VARS['id']);
                             }
                             tep_redirect(tep_href_link($goto, tep_get_all_get_params($parameters)));
                             break;
     // performed by the 'buy now' button in product listings and review page
     case 'buy_now' :        if (isset($HTTP_GET_VARS['products_id'])) {
                               if (tep_has_product_attributes($HTTP_GET_VARS['products_id'])) {
                                 tep_redirect(tep_href_link(FILENAME_PRODUCT_INFO, 'products_id=' . $HTTP_GET_VARS['products_id']));
                               } else {
                                 $cart->add_cart($HTTP_GET_VARS['products_id'], $cart->get_quantity($HTTP_GET_VARS['products_id'])+1);
                               }
                             }
                             tep_redirect(tep_href_link($goto, tep_get_all_get_params($parameters)));
                             break;

 

add

 if ($HTTP_POST_VARS['products_id'] == '29') {
                                  tep_redirect(tep_href_link(FILENAME_PRODUCT_INFO, 'products_id=24'));
                             } else {
                         

Where 24 is the product you want to redirect them to.

 

Above each

  tep_redirect(tep_href_link($goto, tep_get_all_get_params($parameters)));

 

to get this as the final

 

// customer adds a product from the products page
     case 'add_product' :    if (isset($HTTP_POST_VARS['products_id']) && is_numeric($HTTP_POST_VARS['products_id'])) {
                               $cart->add_cart($HTTP_POST_VARS['products_id'], $cart->get_quantity(tep_get_uprid($HTTP_POST_VARS['products_id'], $HTTP_POST_VARS['id']))+1, $HTTP_POST_VARS['id']);
                             }
                             if ($HTTP_POST_VARS['products_id'] == '29') {
                                  tep_redirect(tep_href_link(FILENAME_PRODUCT_INFO, 'products_id=24'));
                             } else {
                             tep_redirect(tep_href_link($goto, tep_get_all_get_params($parameters)));
                             break;
     // performed by the 'buy now' button in product listings and review page
     case 'buy_now' :        if (isset($HTTP_GET_VARS['products_id'])) {
                               if (tep_has_product_attributes($HTTP_GET_VARS['products_id'])) {
                                 tep_redirect(tep_href_link(FILENAME_PRODUCT_INFO, 'products_id=' . $HTTP_GET_VARS['products_id']));
                               } else {
                                 $cart->add_cart($HTTP_GET_VARS['products_id'], $cart->get_quantity($HTTP_GET_VARS['products_id'])+1);
                               }
                             }
                              if ($HTTP_POST_VARS['products_id'] == '29') {
                                  tep_redirect(tep_href_link(FILENAME_PRODUCT_INFO, 'products_id=24'));
                             } else {
                             tep_redirect(tep_href_link($goto, tep_get_all_get_params($parameters)));
                             break;

Thank you both..

 

I tried the second one, and now I get this error....

 

 

Parse error: parse error, unexpected T_CASE in /home/jamesray/public_html/eventscart/includes/application_top.php on line 369

 

This is line 369

 

case 'buy_now' : if (isset($HTTP_GET_VARS['products_id'])) {

 

Any thoughts?

[Given2Fly]

Peterr,

 

Where would I put your code? In the header.php or in shoppingcart.php or?

 

Thanks!

In the future post the whole error message.

 

Sorry, I had not tested this. We just need to take out the else statements. So change it to this.

 

// customer adds a product from the products page
    case 'add_product' :    if (isset($HTTP_POST_VARS['products_id']) && is_numeric($HTTP_POST_VARS['products_id'])) {
                              $cart->add_cart($HTTP_POST_VARS['products_id'], $cart->get_quantity(tep_get_uprid($HTTP_POST_VARS['products_id'], $HTTP_POST_VARS['id']))+1, $HTTP_POST_VARS['id']);
                            }
                            if ($HTTP_POST_VARS['products_id'] == '29') {
                                 tep_redirect(tep_href_link(FILENAME_PRODUCT_INFO, 'products_id=24'));
                            } 
                            tep_redirect(tep_href_link($goto, tep_get_all_get_params($parameters)));
                            break;
    // performed by the 'buy now' button in product listings and review page
    case 'buy_now' :        if (isset($HTTP_GET_VARS['products_id'])) {
                              if (tep_has_product_attributes($HTTP_GET_VARS['products_id'])) {
                                tep_redirect(tep_href_link(FILENAME_PRODUCT_INFO, 'products_id=' . $HTTP_GET_VARS['products_id']));
                              } else {
                                $cart->add_cart($HTTP_GET_VARS['products_id'], $cart->get_quantity($HTTP_GET_VARS['products_id'])+1);
                              }
                            }
                             if ($HTTP_POST_VARS['products_id'] == '29') {
                                 tep_redirect(tep_href_link(FILENAME_PRODUCT_INFO, 'products_id=24'));
                            } 
                            tep_redirect(tep_href_link($goto, tep_get_all_get_params($parameters)));
