i am making attendance system and i want to increment the value in the database if present. i am unable to update the mysql table. can anybody help me here?
your question is very broad. If you want a useful answer, you need to be more specific.
*Why* are you unable to update the DB? Which part are you having trouble with? The form? processing the form? connecting to the DB? the query itself? Give an example of what you've tried, and explain what you need help fixing.
