Product options array when adding to cart

How can I pass options into the add to cart function? I already know how to supply the product_id and the quantity, however, I do not know what information must be in the $options array to add product options to the product.

For example I have the following statement: $this->cart->add( $product_id, $qty = 1, $options = array());

What must be passed to the $options = array()) segment? I assume at least the option_id value must be provided.

An example demonstrating this would be awesome!
Thanks very much!!

In the cart.php file in catalog/controller/checkout/cart.php you can see the main add function being called here: The actual add function in system/library/cart.php meet's the 3 arguments here: There you have your answer. It's the variable $option, which is already an array.

He's asking about the format of the array.

The array can be a few different ways, depending on the option type.

Selectbox & Radio: Checkbox: Text, Date, TextArea: the "252, 253, 254" are the option_ids from the option table
the checkbox values "78, 93, 94, 95" are the option_value_ids from the option_value table
Textboxes are simply stored as a string as entered from the customer.

Take a look at the system/library/cart.php to see how it handles each option type. It looks up the option_id to see what "type" of option it is, then uses the option values for the associated values.

Thank you for your replies!! I am trying to pass checkbox options, however I am still unsuccessful in doing so.

The resulting JSON code shows that the options are still empty for the product:
----start var_dump ($options) for display purposes----
array
'option' =>
array
228 => int 52
----end var_dump ($options) for display purposes----
array
'60:YToxOntzOjY6Im9wdGlvbiI7YToxOntpOjIyODtpOjUy1200' =>
array
'key' => string '60:YToxOntzOjY6Im9wdGlvbiI7YToxOntpOjIyODtpOjUy1200' (length=51)
'product_id' => string '60' (length=2)
'name' => string 'Custom Set' (length=10)
'model' => string 'customset' (length=9)
'shipping' => string '1' (length=1)
'image' => string '' (length=0)
'option' =>
array
empty

I am using the correct ids from the database, so that shouldn't be the issue.

Help is much appreciated! Thanks again guys!!

Any way to pass the Options array from a form. .like list..? How to add the options in this form?


<form action="index.php?route=checkout/cart" method="post">

They already are passed from a form. All you have to do is use Qforia's array formation and look at product.tpl file as an example of the form set up. The options are stored in the $option variable: In your checkout/cart.php file in the add() function you will see this code: This picks up the post data from product.tpl when people are adding options. This is all you need to know in order to fill the $option variable. Aagain, you'll need to look in the product.tpl to mimic how the html fields are set up.
