Hide flexible content is all fields are empty

Hi I know that I can use a conditional statement to check if a particular field is empty.

But how would I do this if I want to check that all fields within a flexible content loop are empty?

You’d need to check every field. I would probably do something like

$sub_fields = array(
  'create',
  'an',
  'array',
  'of',
  'sub_field',
  'names',
);
if (have_rows('flex_field')) {
  while (have_rows('flex_field')) {
    the_row();
    $has_content = false;
    foreach ($sub_fields as $sub_field()) {
      if (get_sub_field($sub_field)) {
        // flex field has content
        $has_content = true;
        // do not need to continue loop once you find content
        break;
      } // end if get sub field
    } // end foreach sub field
    if (!$has_content) {
      // this layout has no content
      // skip it
      continue;
    } // end if !content
    // *********************************************
    // code to display layout here
    // *********************************************
  } // end while have rows
} // end if have rows
