richedit_pre filter-hook . WP 2.0.0

Deprecated in 4.3.0. It is no longer supported and can be removed in future releases. It is recommended to replace this hook with the same one.

Filters text returned for the rich text editor.

This filter is first evaluated, and the value returned, if an empty string is passed to wp_richedit_pre(). If an empty string is passed, it results in a break tag and line feed.

If a non-empty string is passed, the filter is evaluated on the wp_richedit_pre() return after being formatted.

Usage

add_filter( 'richedit_pre', 'filter_function_name_220' );
function filter_function_name_220( $output ){
	// filter...

	return $output;
}

$output(string)

Text for the rich text editor.
