Get All Custom Fields Code
<?php
function display_my_customs($id = 0){
//if we want to run this function on a page of our choosing them the next section is skipped.
//if not it grabs the ID of the current page and uses it from now on.
if ($id == 0) :
global $wp_query;
$content_array = $wp_query->get_queried_object();
$id = $content_array->ID;
endif;
//knocks the first 3 elements off the array as they are WP entries and i dont want them.
$first_array = array_slice(get_post_custom_keys($id), 3);
//first loop puts everything into an array, but its badly composed
foreach ($first_array as $key => $value) :
$second_array[$value] = get_post_meta($id, $value, FALSE);
//so the second loop puts the data into a associative array
foreach($second_array as $second_key => $second_value) :
$result[$second_key] = $second_value[0];
endforeach;
endforeach;
//and returns the array.
return $result;
}
?>
