How to change default worpdress widgets?

Question

PHP

Hello. It is necessary to display arbitrary fields in standard WP widgets (for example, a text widget) that will be added from the admin panel. For example, the class field, which allows you to set your own class for the output text. How to do it? After all, standard widgets are stored in system files and everything will be erased when updating.

Answer 1

Hello. You can copy the widget to your plugin and replace it with the standard one, as, for example, Custom Meta Widget
does .

function customMetaWidget_swap() {
  unregister_widget( 'WP_Widget_Meta' );
  register_widget( 'customMetaWidget' );
} add_action( 'widgets_init', 'customMetaWidget_swap' );

Or find a ready-made plugin, perhaps someone has already implemented what you need
