get_post_meta, get_post_custom array indexing problems

    Hi,

    I’m experiencing some very weird array indexing problems for get_post_meta and get_post_custom.

    In short, I want to have a post where I can enter multiple custom fields of the same type(name)and then extract the value of each and display them on a page in the order they were entered (in my case, the homepage).

    I should also mention I am doing this outside of the Loop.

    Instead of receiving an array that contains the custom field values in the same order I entered them in the admin area, the entries are mixed.

    I tried this:

    <?php

  $custom_fields = get_post_custom(244);
  $my_custom_field = $custom_fields['field_title_here'];
  foreach ( $my_custom_field as $key => $value )
    echo $key . " => " . $value . "<br />";

?>

    and this

    <?php

  $my_custom_field2 = get_post_meta(244,'field_title_here',false);
  foreach (   $my_custom_field2 as $key => $value )
  echo $key . " => " . $value . "<br />";

?>

    Example output:

    0 => Title 3
    1 => Title 4
    2 => Title 1
    3 => Title 2

    The order I entered them in the admin area is ascending:

    Title 1
    Title 2
    Title 3
    Title 4

    Does anyone know what’s happening?

    I have the same problem, meta data seems to be ordered by date modified not meta_id like you would expect 🙁

    Had the same problem.
    Ended up putting together a function to select custom fields.

    General notes here:
    http://blog.tinkerworkshop.com/wordpress-get_post_custom-wrong-order/

    Function is:

    function get_post_custom_X($id){
	global $wpdb;
    $querystr = "SELECT wposts.ID, wpostmeta.meta_ID, wpostmeta.meta_key, wpostmeta.meta_value ".
    			"FROM $wpdb->posts wposts, $wpdb->postmeta wpostmeta ".
    			"WHERE wposts.ID = wpostmeta.post_id AND wposts.ID = ".$id." ".
    			"ORDER BY wpostmeta.meta_id ASC";
	$pageposts = $wpdb->get_results($querystr, OBJECT);
	$return = array();
	foreach($pageposts AS $key=>$val){
		$return[$val->meta_key][] = $val->meta_value;
	}
	return $return;
	//print '<!--'.print_r($return).'-->';
}
