sanitize_bookmark_field( string $field, mixed $value, int $bookmark_id, string $context )

Sanitizes a bookmark field.


Description Description

Sanitizes the bookmark fields based on what the field name is. If the field has a strict value set, then it will be tested for that, else a more generic filtering is applied. After the more strict filter is applied, if the $context is ‘raw’ then the value is immediately return.

Hooks exist for the more generic cases. With the ‘edit’ context, the ‘edit_$field’ filter will be called and passed the $value and $bookmark_id respectively.

With the ‘db’ context, the ‘pre_$field’ filter is called and passed the value. The ‘display’ context is the final context and has the $field has the filter name and is passed the $value, $bookmark_id, and $context, respectively.
