I'm trying to create a custom post meta box that allows a user to select multiple boxes/cells in a grid view. My idea is similar to creating a multiselect or checkbox group, but I don't know how to implement all the options.
array( "name" => "grid_options", "title" => "Test Grid", "description" => 'Select the options from this grid', "type" => "grid", "scope" => array( "post" ), "capability" => "edit_post" ),
...customFields function case:
This only displays the table as I need it, the <input> code is where I'm having an issue. I can use jQuery to manipulate the value of the input when a user clicks on a table cell and it posts the array, but I don't know how to store that array of selections into the post meta when the post is saved/updated.
I've thought of using a "checkbox group" but from my understanding, then I have to specify all 1152 options before-hand in the meta-box array, which is definitely not ideal.
Any idea's on how to accomplish this would be greatly appreciated.
