search form

................
echo '<div class="awqsf_box"><p class="awqsf-button"><input type="submit" id="awqsf_submit" value="'.$options[0]['button'].'" alt="[Submit]" name="wqsfsubmit" title="Search" /></p></div>';
echo '<input type="hidden" name="lang" value=" <?php echo qtrans_getLanguage(); ?> ">'; 

echo '</form>';

Why doesn’t <?php echo qtrans_getLanguage(); ?> work?
