Filters a specific option before its value is (maybe) serialized and updated.

Description

The dynamic portion of the hook name, $option, refers to the option name.

Parameters

$valuemixed

The new, unserialized option value.

$old_valuemixed

The old option value.

$optionstring

Option name.

More Information

This filter is applied to the option value before being saved to the database; this allows the overriding value to be stored. To use this filter, you will need to add filters for specific options names, such as “pre_update_option_foo” to filter the option “foo“.

Source

$value = apply_filters( "pre_update_option_{$option}", $value, $old_value, $option );
