title: Get inputs from multiple textfields to array and insert to db field
body: <p>I have an order form. It has 10 textfields for the user to input a quantity. How do you store the inputs to an array and insert to a db field(separated by comas)? Note: It is NOT required to input on all the textfields. For instance, the inputs are 1,2,3,4..it should appear in the db field also 1,2,3,4</p>
  
  <p>examples and descriptions would be great. I'm relatively new to this.</p>
