Question

I have the following code:

print $node->field_carousel_1[0]['filepath'];

What i would like to do is change the 1 and use a variable instead.

Do you have any idea how i would be able to do this?

What i am aiming for: Using a variable instead of the one to create a looping function to print field_carousel_1, field_carousel_2, field_carousel_3 etc

Answer 1

You can try something like this:

for ($i=1; $i<4; $i++) {
  $field = "field_carousel_$i";
  $arr = $node->$field;
  print $arr[0]['filepath'];
}
