The removal works great with this hook !

To be sure I list all the widgets only after the widgets_init hook :

add_action( 'after_setup_theme', 'hook_the_remove', 1) ;
function hook_the_remove() {
  remove_action('init', 'wp_widgets_init', 1);
  add_action('widgets_init', 'show_widgets_list', 999999) ;
  other_widgets_init() ;
}
function other_widgets_init() {
 	if ( !is_blog_installed() )
		return;

	do_action('widgets_init');
}
function show_widgets_list() {
	global $wp_widget_factory;
	foreach($wp_widget_factory->widgets as $name => $w)
		echo $name . ' - ';
}

I also replaced all my calls to the_widget with this to avoid errors messages in case a widget cannot be found :

function secure_widget($name, $ins, $args) {
	global $wp_widget_factory;
	if (array_key_exists($name, $wp_widget_factory->widgets ))
		the_widget($name, $ins, $args);
	//else echo "<b>$name</b> is not present";
}
function test_widget($name) {
	global $wp_widget_factory;
	if (array_key_exists($name, $wp_widget_factory->widgets ))
		return true ;
	return false;
}

Thanks for your help !

Yes it’s in a plugin file. I don’t see what you mean. The action I’m trying to remove has the priority “1”, which seems pretty early a priority. And it is part of the wordpress core. I don’t see how I can be before.

You mean I should put my

remove_action('init', 'wp_widgets_init', 1);

in another ‘init’ ? Like in this ?

add_action( 'init', 'hook_the_remove', 1) ;
function hook_the_remove() {
  remove_action('init', 'wp_widgets_init', 1);
  add_action('widgets_init', 'show_widgets_list', 999999) ;
  other_widgets_init() ;
}

That sounds wierd. And I tested it, it doesn’t work : the default widgets are still loaded, even if after the others.

I am able to remove it with your code from an ‘init’ action hook callback.

Could you show me your code please ?

have a look at this, I think this is close to what you’re trying to do :

https://justintadlock.com/archives/2010/08/20/linking-terms-to-a-specific-post

Each tool (Preparation, Assessment, etc.) is a custom post. On the WP Admin, each tool is a category;

Not clear for me : is it a custom post or a category ?

If it’s a post, you could use editor for the big text (the_content) and excerpt for the description-preview (the_excerpt : check spelling, I never get it right)

As the big text is just desc + a list, you could even simplier put a “more” separator in you editor and have an automatic exerpt

The patch works fine fot export BUT the import fails :
post created ok
taxonomy terms created ok
post-terms link NOT OK, I have to manually reassign them, THAT sucks !
