manage_(screen_id)_columns filter-hook . WP 3.0.0

Filters the column headers for a list table on a specific screen.

The dynamic portion of the hook name, $screen->id, refers to the ID of a specific screen. For example, the screen ID for the Posts list table is edit-post, so the filter for that screen would be manage_edit-post_columns.

Usage

add_filter( 'manage_(screen_id)_columns', 'filter_function_name_6649' );
function filter_function_name_6649( $columns ){
	// filter...

	return $columns;
}

Default: ''
