How only allow NFT minting after course completion

Question

I am new to ethereum I building a course page where you would get an NFT if you complete the course. Any idea on how to implement it.

Answer 1

you need to have mapping to get track of whether an address is completed the course or not eg: mapping(address => bool) public isCompleted you can updtae this mapping if specefic address completed the course.

you also need a function called getReward then in the function you should check the mapping, you can implement it like this :

function getreward() public{
    bool courseCompleted = isCompleted[msg.sender];
    require(courseCompleted,"not completed the course");

    // if require get passed then the code to transfer or mint the NFT goes here
}
