Question

The following code is for a WordPress plugin, it displays points and tank of a user:

<?php
if(function_exists('cp_displayPoints') && $authordata->ID){
  echo '<span class="cubepoints_buddypress">'; cp_displayPoints($authordata->ID); echo '</span>';
  if(function_exists('cp_module_ranks_getRank')) echo ' <span class="cupepoints_buddypress_rank">'.cp_module_ranks_getRank($authordata->ID).'</span>';
}
?>

I am trying to extract these two echo functions from the If statement but only succeeded with one of them. I can echo the points like this:

<?php cp_displayPoints($authordata->ID); ?>

Works fine. Now I tried doing the same with the second echo:

<?php cp_module_ranks_getRank($authordata->ID); ?>

But it did not work. Obviously, there is some basic thing that I am missing here. Do you know what it is?

Answer 1

The first one likely prints directly to output, while the second returns its value. So, you need to echo() the second one, just as they’re doing in your sample code:

<?php echo cp_module_ranks_getRank($authordata->ID); ?>
