Data stored in the database

  • Hi,

    I wanted to better understand the data saved in the table _postmeta

    I have a field called “name”.
    Why in the database I always have 2 records, for example:

    meta_key: name – meta_value: Harry
    meta_key: _name – meta_value: field_5ae479557b812

    What would be field_5ae479557b812?


  • That is the field key reference. ACF uses that to get the settings for the field so it knows what to do with the value stored for the field in the DB.
