Code snippet: display products with options selected


Recommended Posts

I want to display a product with non-default options already selected. This behavior is achieved when a user clicks on a product in the shopping cart but does not work outside of that specific action. The code below allows options to be passed via the $HTTP_GET_VARS['id[]'] array.


In product_info.php, comment out the existing tep_draw_pull_down_menu() function call and add:


if ($cart->contents[$HTTP_GET_VARS['products_id']]['attributes'][$products_options_name_values['products_options_id']]> 0) {

 $default_options_value = $cart->contents[$HTTP_GET_VARS['products_id']]['attributes'][$products_options_name_values['products_options_id']];


elseif ($HTTP_GET_VARS['id'][$products_options_name_values['products_options_id']] > 0) {

 $default_options_value = $HTTP_GET_VARS['id'][$products_options_name_values['products_options_id']];


else {

 $default_options_value = '';


echo tep_draw_pull_down_menu('id[' . $products_options_name_values['products_options_id'] . ']', $products_options_array, $default_options_value);


The if() evaluates true if the user clicks on their cart product (the standard behavior). The elseif() evaluates true if the GET variable id[$foo] -- where $foo is the current product option id -- is greater than 0.


To test it out, find the option id and values by viewing the html source for the product, looking for <select name="id[2]"><option value="43"> or somesuch code. Then call product_info.php?products_id=52&id[2]=43 (with your numbers inserted of course).


Hope someone finds this useful. Please let me know if anything looks awry.

Thanks for the posting... I've been trying to do something like this for a while and no luck

I tried to implement this code and when I clicked on the "add to cart" button I got a stream of messages on the left side of screen such as

Warning: in_array(): Wrong datatype for second argument in /public_html/cart/includes/boxes/categories.php on line 31

The page still diplayed the item added to cart but where the "option" is usually shown I just received a dash.


Also, since you already twicked with the code that is in charge of the product's options, do you know how I can just get the option a user chose and pass its value to another page. In the next page I want to take that "option" value that was passed and only then add it along with the product to the cart -- do you have any ideas of how I can implement this??


Thank you

Who would have thought that so much can be created from 0`s and 1`s...
