WP_Widget_Block::get_dynamic_classname( string $content ): string
Calculates the classname to use in the block widget’s container HTML.
Contents
Description
Usually this is set to $this->widget_options['classname'] by dynamic_sidebar() . In this case, however, we want to set the classname dynamically depending on the block contained by this block widget.
If a block widget contains a block that has an equivalent legacy widget, we display that legacy widget’s class name. This helps with theme backwards compatibility.
Parameters
-
$contentstring Required -
The HTML content of the current block widget.
Return
string The classname to use in the block widget's container HTML.
