Multiple Record Inserts

currently working on an app that lets users register their career history details with us.The form that captures data has 7 fields which are repeated four times. i.e. the user can enter up to four past employers, four job titles etc. Currently there are four instances of each field which all share the same name (four fields named Employer, four fields named Jobtitle etc...).

I'm guessing the best way to write all the info back to the Database is to split the form data into an array and then use a Looping or For i = 0 to whatever..... type structure but i can't figure out how it should be done or if this is even the right way to do it.
