    I have three websites, all are implemented with pure PHP, pure CSS and jQuery. I need you to design and implement a simple purchase feature that allows user to click a Buy button, after which user's details are asked and then he can pay the product using the Paddle payment system.

The system must support discounted prices that can be implemented simply by a hard-coded PHP variable. For example, let's say we have $price_normal = 20; (i.e. normal price is 20 ...

    It is an online clothing store. We have variable products configured with color and size attributes, for example a product can have 2 variations; Green/Any size and Black/Any size. There is an image of the product in the corresponding color for each variation, but at the moment the image does not change unless a color AND size is selected (I know this is how Woo works out of the box). We would like to make it so that the image changes when ONLY one color is selected. I have code that allows the variation image of a product to change when only the main attribute (e.g. color) is selected, rather than having to select all the variation attributes (e.g. color and size) for the image change. I would like to adjust this code to my woocommerce *My Budget is $30 fully*
