   I need some coding help here. I want to capture a custom field and using an "if not null statement echo output in a link form". Here's what I thought would work but does not:

   <?php if ( $wpcm_number_facebook != '' ) { echo '<li><span class="number">'<a href=\"' . $wpcm_number_facebook. '\" /> (facebook) </a>' </li>'; } ?>

   <?php
   // $fieldnm is null if the custom field doesn't exist
   $fieldnm = get_post_meta($post->ID,'yourfieldname',true);
   
   // If the field exists
   if($fieldnm) { ?> YOURHTMLHERE <?php } 
   
   // Field is null (doesn't exist)
   else { ?> SOMEOTHERHTML <?php }
   ?>

   Or using echo..

   <?php
   // $fieldnm is null if the custom field doesn't exist
   $fieldnm = get_post_meta($post->ID,'yourfieldname',true);
   
   // If the field exists
   if($fieldnm) { echo 'something to echo'; } 
   
   // Field is null (doesn't exist) // Remove if not needed
   else { echo 'the field is null'; }
   ?>

   Hope that helps...

   Update 'yourfieldname' with your actual custom field name.
