WordPress Development Stack Exchange is a question and answer site for WordPress developers and administrators. It's 100% free, no registration required.

I am trying to create a metabox input field in a custom post type and it does not work even if I followed the instructions the best I could. I am not a PHP dev so I guess it could be just a small thing that is missing or it is wrong.

By not working I mean, I does not show at all in the WP UI.

Here is the code:

The other issue is that the Tag is not named even if the function is there.

Thank you in advance. Eri

A question should not rely on a link to an external website. Put the code into your question please. –  toscho Oct 30 '12 at 2:33

In the code, you are trying to pass functions as parameters in add_action(). That syntax works in javascript, but not so well in php. Try doing it with passing the function name instead in add_action()

Lambda functions are working fine in PHP 5.3+. –  toscho Oct 31 '12 at 3:32
