Thanks for your opinion @brenfm. I have already used that but I can’t get what I’m intend to do.
Well, my intention is to put some data in a custom post type called services with small thumbs (icons) and then give the user capability to choose from these alternatives. However, when a user checks some of the check boxes, it is intended that the thumbs to be published in a row and the value should be displayed as tooltip.
Of course, this could be solved by calling the values into the custom field (as discussed earlier in this post) but I can not get the value or the thumb to be published.
For example, The values of the custom post type appears in the custom field (check boxes and select box) but when I intent to retrieve the value, I get only the ID’s of the post types and not the values. Meanwhile, even empty values appearing with list buttons without any value.
Is there any way to retrieve the thumb, value and the key by any code and at the same let the empty values to be ignored?
Please, anyone!
Any help is appreciated.
