title: Multiple select array not sending data
body: <p>as ussual I wanted to use multiple select. </p>
  
  <pre><code>&lt;select  multiple="multiple" class="form-control" name="kraj[]"&gt;
  &lt;option value="1"&gt;Středočeský&lt;/option&gt;
  &lt;option value="2"&gt;Jihočeský&lt;/option&gt;
  &lt;option value="3"&gt;Plzeňský&lt;/option&gt;
  &lt;option value="4"&gt;Jihomoravský&lt;/option&gt;
  &lt;option value="5"&gt;Vysočina&lt;/option&gt;
  &lt;option value="6"&gt;Moravskoslezský&lt;/option&gt;
  &lt;option value="7"&gt;Ústecký&lt;/option&gt;
  &lt;option value="8"&gt;Olomoucký&lt;/option&gt;
  &lt;option value="9"&gt;Kralovehradecký&lt;/option&gt;
  &lt;option value="10"&gt;Pardubický&lt;/option&gt;
  &lt;option value="11"&gt;Zlínský&lt;/option&gt;
  &lt;option value="12"&gt;Karlovehradecký&lt;/option&gt;
  &lt;option value="13"&gt;Liberecký&lt;/option&gt;

  <p>But this time i am not getting data from this. Other parts of form working properly but after selecting some options i get an empty array of kraj[]. print_r looks like:</p>
  
  <p>`Array
  (   ...</p>
  
  <pre><code>[delka] =&gt; 5000
  
  [kraj] =&gt; 
  
  [onoffswitch] =&gt; on
  ...
  </code></pre>
  
  <p>)`</p>
  
  <p>I just cant see, what is wrong, im kinda desperate. Deadline tommorow, and stuck at this :D</p>
