Attempting to insert multiple values using PHP JQuery AJAX which is quite a headache for beginners of Web Development.
Note that :- These are only attempts. The upper first and third one is not mine as it belongs to some another user and used for reference but the bottom one which is modification is done by me. Cannot guarantee that it will work but I can give 50% assurance of work if correct changes are implemented.
