Hi, I have a problem and a doubt at the same time.
Custom Table 2.1.1
First, what is the purpose of the third parameter Key
MB_Custom_Table_API::create( $table_name, $columns, $keys = array() ); I may be missing something in the translation into my language.
Now I see a problem, I'm using the example in the documentation with the address-phone-email fields and the key email parameter, but when I have the keys parameter enabled when saving a post the fields are not saved in the database, and when remove the optional key field the data is saved normally.
Can you please share the code that you are using to create the custom table and custom fields? And share your database info. Somehow in my demo site, I have to use the third parameter $key to save the data to the custom table.
keys Array of key column IDs. These columns will be indexed. Optional.
