   Hi Everybody,

   I have a problem I try to get meta data value to put them in an php array but doesn't work well.

   I get my value called slidecolortochange but when I add it into my array the size is just 1 but my array should be 2.

   If I add directly my value into the array it works fine, i get the right size.

   What Im doing wrong?

   if ( get_post_meta($post->ID, 'slidecolortochange', false) ) : ?>
   
   <?php $slidecolortochange = get_post_meta($post->ID, 'slidecolortochange', true);
   
   	$slidecolortochange = trim($slidecolortochange);
       //echo $slidecolortochange; 
   
   	$test = array($slidecolortochange);
   	print_r($test);
   	$size = count($test);
   	echo 'size : '.$size;
   
   endif; ?>

   Regards

   I think the issue is that this code:

   <?php $slidecolortochange = get_post_meta($post->ID, 'slidecolortochange', true);

   should be changed to:

   <?php $slidecolortochange = get_post_meta($post->ID, 'slidecolortochange', false);

   The true in the first code block shown above tells WordPress to only retrieve a single meta value, even if multiple meta values are stored in the database.

   I've tried before but that give me an array into another one.

   I got that:
   

   Array
   (
       [0] => 3=>'roro', 5=>'toto'
   )
   size : 1

   And my custom field value is: 3=>'roro', 5=>'toto'

   Maybe Im doing wrong. I just want to get a number associated with a name.

   Do you have another idea to make it?

   In that case, try:

   <?php $slidecolortochange = maybe_unserialize( get_post_meta($post->ID, 'slidecolortochange', true) );

   and see if that works for you.
