   Hi I'm rading through a series of tutorials on how to use Wordpress Custom Fields. It is maybe a little bit over my standard, as my PHP knowledge is pretty limited. This is from the website, but could anyone explain a bit more in depth, whats going on so I can google my way to the rest.

   From the website: http://justintadlock.com/archives/2007/10/16/using-wordpress-custom-fields-subtitles

   The CODE
   //
   

   $subtitle = get_post_meta
   ($post->ID, 'subtitle', $single = true);
   if($subtitle !== '') echo ': ' . $subtitle;

   //

   The explanation from the site:

   "This code pulls your custom field key of “subtitle” out and displays it on whatever pages have a subtitle."

   please elaborate and in PHP language explain what the different things mean.

   Thanks

   By doing my own research I now understand how to use this.

   I guess it was the if statement that I didn't really knew how to use. And the (not equal to) also confused me a bit.

   Basically the not equal too part of the code checks that the custom field has a value before echoing it.
