title: Weird Variable / Mysql Issue
body: <p>I just don't know what to do, and don't know how to search about this weird problem. Here is is:</p>
  
  <p>All the connection on the page are working correctly, just in case:</p>
  
  <p>I Have this code to update an Email on the Database</p>
  
  <pre><code>$fUsername = mysql_real_escape_string($_GET['user']);
  $fPassword = mysql_real_escape_string($_GET['senha']);
  $fEmail = mysql_real_escape_string($_POST['fEmail']);
  
  $sql = "UPDATE usuario SET email='$fEmail ' WHERE username = '$fUsername' and senha = '$fPassword'";
  $result=mysql_query($sql);
  </code></pre>
  
  <p>Now, the Problem:</p>
  
  <p>This query is not Updating the "Email" field on the BD. It just makes the field empty.</p>
  
  <p>If I echo the $sql var, I get this:
    UPDATE usuario SET email='teste@gmail.com ' WHERE username = 'teste1' and senha = 'e10adc3949ba59abbe56e057f20f883e'</p>
  
  <p>If I ran manually this query on the mySQL, it updates the field like I want.</p>
  
  <p>If I manually pass a value to the $fEmail var (<strong><em>$fEmail = "teste@gmail.com"</em></strong>). It works just fine.</p>
  
  <p>The only way that don't work is when I take the value from the <strong>Form</strong>.</p>
  
  <p>Does anyone have the solution for this? D:</p>
