Callback function to filter non-multidimensional theme mods and options.
Description
If switch_to_blog() was called after the preview() method, and the current site is now not the same site, then this method does a no-op and returns the original value.
Parameters
$originalmixedrequired- Old value.
Source
public function _preview_filter( $original ) {
if ( ! $this->is_current_blog_previewed() ) {
return $original;
}
$undefined = new stdClass(); // Symbol hack.
$post_value = $this->post_value( $undefined );
if ( $undefined !== $post_value ) {
$value = $post_value;
} else {
/*
* Note that we don't use $original here because preview() will
* not add the filter in the first place if it has an initial value
* and there is no post value.
*/
$value = $this->default;
}
return $value;
}
