Question

I have a form with input=file. I’d like to validate in with javascript/jquery and check if the file field is filled. How can I do this ?

Answer 1

$(document).ready(function() {
  $('#my-form-id').submit(function(ev) {
    if (!$('#my-file-input-id').val()) {
      ev.preventDefault();
      alert('Please select a file to upload.');
    }
  });
});
