Import CSV data to fields in MySQL Database
Question
I am trying to upload a CSV file which contains the fields stated in the link below [see CSV example] via a web form. The user can browse their computer by clicking the upload button, select their CSV file and then click upload which then imports the CSV data into the database in their corresponding fields. At the moment when the user uploads their CSV file, the row is empty and doesn't contain any of the data that the CSV file contains. Is there a way i could solve this so that the data inside the CSV file gets imported to the database and placed in its associating fields?
CSV example:
