Overwrite product atrribute

[chillermiller]

Hello everybody,

 

i have a product with two attributes 'color' and 'size'. The client ist able to choose between 200 colors so I implemented a custom colorpicker.

 

When the user clicks "add to cart" I want to pass the choosed color as an attribute to the product object itselt.

{if ($group.group_type == 'select')}
<select name="{$groupName}" id="group_{$id_attribute_group|intval}" class="form-control attribute_select no-print">
{foreach from=$group.attributes key=id_attribute item=group_attribute}
<option value="{$id_attribute|intval}"{if (isset($smarty.get.$groupName) && $smarty.get.$groupName|intval == $id_attribute) || $group.default == $id_attribute} selected="selected"{/if} title="{$group_attribute|escape:'html':'UTF-8'}">{$group_attribute|escape:'html':'UTF-8'}</option>
{/foreach}
</select>

{hook h='CustomHook'}

At the moment, I got my variables in jQuery in the "CustomHook".

 

Hoch can i make overwrite the procedure from prestashop provided?
