Removing the share buttons from listing sidebar

first req – a bit outside the scope of support, but I hope you can help me learn a bit more about how to use filters —

I want to modify this function I found in geodirectory_hooks_actions.php

function geodir_detail_page_sidebar_content_sorting()
{
	$arr_detail_page_sidebar_content =
	apply_filters('geodir_detail_page_sidebar_content' , 
					array( 	'geodir_social_sharing_buttons',
							'geodir_share_this_button',
							'geodir_detail_page_google_analytics',
							'geodir_edit_post_link',
							'geodir_detail_page_review_rating',
							'geodir_detail_page_more_info'
						) // end of array 
				); // end of apply filter
	if(!empty($arr_detail_page_sidebar_content))
	{
		foreach($arr_detail_page_sidebar_content as $content_function)
		{
			if(function_exists($content_function))
			{
				add_action('geodir_detail_page_sidebar' , $content_function);	
			}
		}
	}
}

I can get what I’m after by commenting out

//'geodir_social_sharing_buttons',
							//'geodir_share_this_button',

But then of course I’m modifying the core plugin which I don’t want to do.

I tried a few things in the functions.php – for example adding:

remove_filter('geodir_detail_page_sidebar', 'geodir_social_sharing_buttons');

I also tried this:

function geodir_sidebar_custom() {
						array( 	//'geodir_social_sharing_buttons',
							//'geodir_share_this_button',
							'geodir_detail_page_google_analytics',
							'geodir_edit_post_link',
							'geodir_detail_page_review_rating',
							'geodir_detail_page_more_info'
							); // end of apply filter
}
add_filter('geodir_detail_page_sidebar_content', 'geodir_sidebar_custom')

Neither had the intended effect.

In the original code – it’s a variable which is then pulling a filter which is itself an array of functions… pretty nesty!

My theme has share buttons baked in already that look really nice so that’s why I’m trying to hide them.

FWIW – a feature request is to just turn those into widgets as well… it would make things more plugin-like and less theme like — I was surprised those elements where so baked in when the other elements in the listing side bar are widgeted – the my dashboard, map and popular listing stuff.

Thank you for helping me with a little copy paste code or refer me to a better tutorial – I’ve been through the codex and a few other tuts out there – but clearly not got my head around how to apply what I’ve learned to this situation.
