This project is in opencart 220.127.116.11 Arabic ver.
I have this website where students can pay for their in classroom course.
Every three courses we have are given at the same time, so I set them in one product with three options (in radio button).
So one student can be in one of these three (same time) courses. But, I have a problem. If the same student goes back and add another same time course by mistake. I want to stop this from happening by doing this:
Rule: if any option from product (A) is in cart, then product (A) display is blurred or grayed out and can't be used. If product (A) is deleted from cart, then product (A) display will be back to normal. all products will have same rule, no limits to cart. No text or warning messages to students (just visually show the student that the product is unavailable) this is why I did not want to use any of the available extensions.
- I have opencart ver. 18.104.22.168 in Arabic.
- All students inter the site as Guest.
I need this done ASAP.
