If /else does not work with empty fields

  • Hello! I need help to solve this problem. How I can hide the data in a custom field that is empty? I tried many ways and I’m breaking my head.

    <div class="flexslider">
  <ul class="slides"><li><?php
 if ( has_post_thumbnail()) {
   $large_image_url = wp_get_attachment_image_src( get_post_thumbnail_id(), 'large');
   echo '<a href="' . $large_image_url[0] . '" rel="lightbox[usb]" . title="' . the_title_attribute('echo=0') . '" >';
   the_post_thumbnail('medium');

   echo '</a>';
 }
 ?></li>

 <?php
   $fotos = get_order_field('fotos_fotos');
   if($fotos != ''){
   foreach($fotos as $foto){
      // el segundo parametro de la función get y get_image es el indice del grupo a mostrar
      print '<li>';
      printf('<a href="%s" rel="lightbox[usb]">', get('fotos_fotos',1,$foto) );

      printf('%s', get_image('fotos_fotos',1,$foto) );
	   print '</a>';
      print '</li>';
   }
 }  else {
print '';
}
?>
 </ul>
 </div>

   echo '<a href="' . $large_image_url[0] . '" rel="lightbox[usb]" . title="' . the_title_attribute('echo=0') . '" >';
   the_post_thumbnail('medium');

   echo '</a>';
 }
 ?></li>

 <?php
   $fotos = get_order_field('fotos_fotos');
   pr($fotos);
   foreach($fotos as $foto){
      // el segundo parametro de la función get y get_image es el indice del grupo a mostrar
      print '<li>';
      printf('<a href="%s" rel="lightbox[usb]">', pr(get('fotos_fotos',1,$foto) ));

    it is strange that the get_order_field function returns having 1 field, but the get function returns no information, you could have a backup of the DB
