I want to write an if else statement that takes up to 4 image fields. If only one image is uploaded it will only show that in a col-12 grid. If two images are uploaded it will show each image in col-6 grid. If three images are uploaded it will show two images in col-6 and the third in col-12. If four images are uploaded it will show each in a col-6 grid. Please help.

What are the names of your fields? What are the return values of your fields?

This is just a general idea because I don’t have the details.

<?php 
// get all for fields and add them to an array
$images = array();
$images[] = get_field('image_field_1');
$images[] = get_field('image_field_2');
$images[] = get_field('image_field_3');
$images[] = get_field('image_field_4');

$current_image = 0;
foreach ($images as $image) {
  $class = 'col-12';
  if (($current_image == 0 || $current_image == 2) && isset($images[$current_images+1])) {
    $class 'col-6';
  }
  ?><div class="<?php echo $class; ?>">image here</div><?php 
  $current_image++;
}
