Enable inline editing for all custom fields
Admin Columns support inline editing for custom fields.
Only use this when you are well aware of any formatting and validating rules on how your custom field value is stored. For example, inline edit will not work on serialized custom field data.
Most editable fields will be text fields and contain the raw value of the custom field.
A few other fields will store the values according to this list:
|Checkmark||Displayed as single checkbox. Value will be stored as 1 or 0|
|Media Library||Displays the media library popup. Value will be stored as an integer (attachment ID)|
|Post title||Displays a selection dropdown with posts. Value will be stored as an integer (post ID)|
|User||Displays a selection dropdown with users. Value will be stored as an integer (user ID)|
|Multiple values||Not supported.|
To enable inline editing for Custom Fields got to the settings tab and click ” Enable inline editing for Custom Fields”.
If you are a developer and you like to modify the custom fields value before it’s being stored to the database. These related filters will allow you to hook into Admin Columns:
