title: get_metadata WordPress function is not working
body: <pre><code>$transactions = get_metadata( 'post', '', '_pfund_transactions' );
  </code></pre>
  
  <p>Not sure what I'm doing wrong. I specified the type and the key. I also left the object ID blank as I'm not sure what should go there.</p>
  
  <p>Here's an example of the data involved in the meta_value field.</p>
  
  <pre><code>a:6:{s:7:"success";s:1:"1";s:6:"amount";s:1:"1";s:11:"donor_email";s:16:"test@test.com";s:16:"donor_first_name";s:4:"adsf";s:15:"donor_last_name";s:3:"dfs";s:17:"transaction_nonce";s:22:"xxxxxx";}
  </code></pre>
  
  <p>The result appears to be empty as the statement below is true</p>
  
  <pre><code>if (! empty( $transactions ) )
  </code></pre>
