I'm trying to add extra functionality to a WordPress/WooCommerce free plugin but I got stuck. I hope I can explain properly because I am not a developer.
The plugin stores all the data (product options) in a dedicated index in wp_options table, as a serialized array.
What I want to do is to create/read/update/delete the product ID in this array based on the status of a checkbox. Something like: - if this product has this option, show a ticked checkbox - if not, add this option to this product when the checkbox is ticked - remove this option from this product when the checkbox is unticked.
But I've noticed the plugin sores it in two locations within the same array, here [conditional_rules_json] => [[[{"subject":"product","comparison":"equals","cvalue":["11","20"]}]]]]
and here
[value] => Array (
[0] => 11
[1] => 20
).
11 and 20 are the IDs of the products that are using this option now.
I don't understand how I am supposed to update the IDs based on the status of the checkbox. Am I supposed to update it in both locations or just one? And how can I do it? str_replace?
