You could always just use the built-in WP get_post_meta() function. You might have to do some data manipulation if you want the image src, but it’s definitely doable, since CCTM just saves field values as postmeta.
The problem I’m running into is that I need to try and turn the post id into the image id for the custom field.
I’ve tried these, but I don’t get the image id or the URL to the image:
$post_thumbnail_id = get_custom_field($post_ID, 'wine_bottle_image');
$attachmenturl = get_custom_field($post_ID, 'wine_bottle_image');
$attachmenturl = get_custom_field($post_ID, 'wine_bottle_image:to_image_src');
If I hard code an image ID, I get the correct image
$post_thumbnail_id = 437;
$attachmenturl = wp_get_attachment_url($post_thumbnail_id);
Any suggestions?
Have you verified that the other plugin is storing the value as expected in the wp_postmeta table? The get_post_meta() function would be a more transparent window into that table.
Your syntax for get_custom_field() is incorrect: that function is meant to be called within the context of an existing post (i.e. the post-id is implied). See https://code.google.com/p/wordpress-custom-content-type-manager/wiki/get_custom_field
It expects a field name, NOT a post id. You will not have a custom field named 1 or 2 or whatever the post id is.
