title: Retrieving database info while requesting other data
body: <p>I am not sure how to fix this issues.
  Basicly, I need to be enable to retrieve data from a database.
  But this needs to be limited to the users account plan. 
  For example: an user has a membership plan, which comes with 5 emails. 
  He will need to be enable to see 5 emails, instead of my whole email database getting extracted. </p>
  
  <p>Code:</p>
  
  <pre><code>$SQLSelect = $odb -&gt; query("SELECT * FROM `accounts` ORDER BY `ID` DESC LIMIT = '" . ($_POST['email']) . "'");
  </code></pre>
