About 'Smarty' variable, how to handle it

[DyO13]

Hello everyone, im having a problem with a 'Smarty' variable.

I should say that in the shop im currently working, we sells books, audio-cd's, etc. And there is an option for the audios to get downloaded for a minor price or less points (we use a bonuspoints system).

So in the templates/modules/product_options, i've seen that on products_options_selections_html, there is an input, that shows all the selections, and each item is sorted by values, e.G

Code: PHP  [Auswählen]

 {foreach key=key_data name=key_data item=item_data from=$options_data.DATA}
 
  <input type="radio" name="id[{$options_data.ID}]" value="{$item_data.ID}" {if $smarty.foreach.key_data.first} checked {/if} />
    {$item_data.TEXT} {if $item_data.PRICE!=''}( {$item_data.PREFIX}{$item_data.PRICE} ){/if}
    <br />
    {/foreach}

What i desperate want, is to know how is value="{$item_data.ID}" handled. Im sure that this variable comes from products_attributes.php on 'includes/modules', the ID i mean.

My purpose on knowing this is to relate the value with a specific cart submit.

e.G

Instead of clicking the second 'item' of the input to add it to the shoppingcart, i just want to click on a button i already made in products_info.php which will directly "pick" that option for me and add it to the shopping cart.

Im pretty sure that "all i need to do" is to somehow set the "{$item_data.ID}" variable on the .php file (or even .html part if possible through Smarty) where the button i already implemented is

How is this possible? or maybe i should do it on cart_actions.php? (here i put a new "submit_to_cart" script for buying with bonuspoints

Can it be possible to set the variable from another file which is not product_attributes.php to make it happen, like in product_info.php?

I'll attach a pic.


Note: I wouldn't be asking here if i haven't been spending so much time looking for it. Thanks in advance

What argues against a javascript routine ?
Write a short function with the help of jQuery (I suppose you have jQuery implemented anyway like it is per default) which checks the respective radio button and assign the function to the button via onclick="YOUR_FUNCTION()".

Since we don't know exactly which processes will be launched when clicking that download button I don't have a better idea so far.

*EDIT*
On the other hand /includes/cart_actions.php should be the right place to handle your demands via php by setting the $_POST['id'] (which is the option choosen) may be hard-coded, insofar as it is always the same id.

Thanks a lot! I've been trying before with the $_POST['id'], but i was not getting any result, so i though i wasn't the way of how to do it. But now that you confirm it, i was totally sure, and i could finally do it.
Really big thanks for the help, im so grateful for real. Have a nice day!
