I have a mysql database for various music genre. What I want to do is, I want to relate all my blog posts to specific genre. For that I have to add custom field in wordpress add/update post form. This will include the custom meta box with list of checkboxes. These checkboxes are generated using the “genre” table. I also want to allow multiple checkbox selection.
In database it should be stored in a table like this
post_genre_master
------------------------
id (auto generate)
post_id
genre_id
I tried to create a code for static values like this the one on below link but for empty values, but this lose the array indexes when some checkboxes are not selected.
The “act_id” in this code sample is actually “genre_id”
