I know how to do that in pure SQL but I can’t get WP_Query to nest conditions in the way required. If it is acceptable, the easiest way to make this work would be to assign an arbitrary far future end date when the data is saved to the database. Something like strtotime(“2038-01-01”). That is … Read more
I’m not sure if select multiple value from the select box is what you want, but from a quick look at you code i would say you should put <select name=”‘.$field[‘id’].'[]” id=”‘.$field[‘id’].'”> instead of <select name=”‘.$field[‘id’].'” id=”‘.$field[‘id’].'”> since you want a multiple select.

You don’t appear to be setting meta_box_nonce anywhere in your code. As your cd_meta_box_save function returns if the nonce isn’t set, your fields will not be saved. See the codex for more on nonces.

You should be able to pass the name of the custom field in the shortcode: [cgview title=”fieldname”] Not tested; I just took a look at the source code (and now my eyes hurt).
Output during saving You can not print something during the data is saved. If you use die( var_dump( $your_var ) ); it will print the values, but also stops the script. The reason is, first the data will be parsed. Then you will be redirected back to profile.php. So everything you print while parsing the … Read more
Post thumbnail size for custom field only
Custom fields are not intended as grouping mechanism, they are suited for data that can have wildly different values that are not group like. For example product weight would be a good candidate since it can wildly vary and typically there is no interest in grouping like “show me all products that weight 200g”. For … Read more
