   Greetings,

   I can't get the value of a custom field assigned to a string variable inside a plugin for the life of me.

   Here is what I've done so far..

   I added this function to functions.php in my theme..

   function get_custom_field_value($szKey, $bPrint = false) {
   	global $post;
   	$szValue = get_post_meta($post->ID, $szKey, true);
   	if ( $bPrint == false ) return $szValue; else echo $szValue;
   }

   Inside the plugin, I added this code..

   if ( function_exists('get_custom_field_value') ){
      $custom_field = get_custom_field_value('custom_field_name', false);
   }

   Where custom_field_name is the name of my custom field.

   So, I add a new post, select the custom field and give it a value, add it. Publish the post.

   The value never gets assigned to $custom_field.

   I've searched the web and all posts seem to lead back to using this method. I just can't get it to work

   Where am I going wrong here?

   Thanks!!

   Works just fine for me using the WordPress Default theme's index.php if the code is placed before the endwhile statement (meaning inside The Loop).

   Thanks for your response.

   Isn't this code supposed to work outside the loop? I'm trying to assign the value of a custom field to a variable inside a plugin.

   $custom_field = get_custom_field_value('custom_field_name', false);

   If I manually assign a constant to $custom_field everything works fine with the constant but the above code always returns a null string.

   Does my does my code and logic seem sound?

   No--because you are using $szValue = get_post_meta($post->ID, $szKey, true); and $post->ID would be set in the loop.

   Otherwise you'll need to pass the post ID in your arguments.
