title: How to not pass empty input fields in HTML form
body: <p>I have a form that has about a hundred input/text fields for each of our companies products. The form is to be filled out at the end of the day with the number of each product that was sold.</p>
  
  <p>How do I have the form only pass on the relatively small subset of fields that are NOT empty?</p>
  
  <p>I'm not looking for form validation. It's ok for the user to either enter or not enter a value in any of the input fields; however I only want the input fields that did have a value entered into them to be included in the POST that the form passes along.</p>
  
  <p>Thanks</p>
