I just installed the computed fields module and I'm a little lost as to how to use it. I have 2 fields in my content type: field_shortdesc
and field_audio_description
.
If field_shortdesc
is blank I need to display field_audio_description
and vice-versa.
What code do I need to place into the computed code and display code areas? Seems like I can't get even the simplest code to work.
For example if I put $entity_field[0]['value'] = "test";
in the computed area and then put print $entity_field[0]['value'];
in the display code area nothing gets printed out. Obviously I'm doing something completely wrong.
Note the help text in the Display Code section states:
This code should assign a string to the
$display_output
variable, which will be printed when the field is displayed.
Instead of print $entity_field[0]['value']
try $display_output = $entity_field[0]['value']
