   Hi there

   Just learning WP and I would appreciate your help with this. I have number of custom posts in my wordpress and I need to pull custom filed from each type of post to homepage.

   Now first post type have field 'imag1', second type have 'imag2', 3rd, 'imag3' etc. How can I call all those values to be shown in one spot. So I want to say show imag1 or imag2 or imag3 - which ever is related ot current post.

   I know how to call one custom field value, works perfectly with:
   <?php echo get_post_meta($post->ID, "imag1", true); ?>

   But how do I call to show any of above?

   Thx a lot good people!

   hi dean_l

   You can use this
   <?php get_post_custom($post_id); ?>

   or make an array of your metakeys and thne start loop and in that loop write your code mean

   <?php echo get_post_meta($post->ID, "imag1", true); ?>

   get_post_meta(); returns an empty string if the Post doesn't have the custom field. You can test it like so:
   

   $image_meta = get_post_meta($post->ID, "imag1", true);
   if($image_meta != '') {
   // post has imag1 meta value -> do stuff
   }

   But why do they all have to be different (imag1, imag2, 'imag3') when they (probably) do the same thing?

   This may work not tested
   

   <php?
   $post_meta = get_post_meta($post->ID);
   foreach ($post_meta as $output) :
   	$pos = strpos($output, 'imag');
   	// Note our use of ===, because == would not work as expected
   	// the position of 'imag' is the 0th (first) character.
   	if ($pos === true) {
   		echo get_post_meta($post->ID, $output, true);
   		return;
   	}
   endforeach;
   ?>

   @Digital Raindrops
   I think the second argument ($key) is required:

   But maybe I'm wrong.

   Thanks keesiemeijer,

   I think the second argument ($key) is required:

   Quite correct, however I had to investigate, this code works and I have tested it, where it selected the correct value (5) from these custom fields.

   Array(
   [0] => _thumbnail_id ($pos = null)
   [1] => _edit_lock ($pos = null)
   [2] => _edit_last ($pos = null)
   [3] => thumbnail_image ($pos = 10)
   [4] => the_image ($pos = 4)
   [5] => image_1 ($pos = 0)
   [6] => iimage_1 ($pos = 1)
   )

   Returns image_1 value "Image number 1"

   <?php $post_meta = get_post_custom();
   	$keys = array_keys($post_meta);
   	foreach ($keys as $output) :
   		$pos = strpos($output, 'imag');
   		// Note our use of === 0, because == would not work as expected returns null or false
   		// the position of 'imag' is the 0th (first) character.
   		if ( $pos === 0 ) {
   			echo get_post_meta($post->ID, $output, true);
   			return;
   		}
   	endforeach;
   ?>

   Interesting that the '_thumbnail_id' is stored in the post meta!
   [_thumbnail_id] => Array( [0] => 227 )

   HTH

   Great. Thanks a lot Sangram, Kessie and David.
   I trying to make kind of custom product listing, so lot of values. This will help to sort them out and display on the homepage. Cheers
