Computed Field display only if below 0

Question

In my computed field I'm trying to make it display the field and it's label only if the value is negative. If it is above 0 it should not display anything, not even field label.

So far in "Display Code (PHP)" I have:

if $entity_field_item['value'] < '0' { ;
$display_output = $entity_field_item['value'] . '%';
}else{$display_output = ''};

But it just returns the label with no value.

The classic

$display_output = $entity_field_item['value'] . '%';

works fine though.

Answer 1

Try this:

if ($entity_field_item['value'] != 0)
 {
 $display_output = $entity_field_item['value'] . 'pkt';
 }
 else($display_output = NULL);

Answer 2

One issue that I can see is in the if condition $entity_field_item['value'] < '0'

You should remove the quotes from $entity_field_item['value'] < 0 this should make the if condition as expected. But the Label would still be visible.

To remove that you would need to use the patch from the below link
