Filter bloginfo_rss only passes one argument

[tzafrir]

According to ​The codex the filter bloginfo_rss should pass a second argument, $show, that tells exactly what blog info is called.

However, in feed.php:

function bloginfo_rss($show = '') {
	echo apply_filters('bloginfo_rss', get_bloginfo_rss($show));
}

Only the content argument is passed.

As expected, when trying to use the second argument in the filter function, I receive a warning: Missing argument 2.

I'm aware that one way to solve this is to remove the wrong part from the codex, but I'm hpoing more towards actually having that feature, becuase right now it makes it impossible for me to filter only bloginfo_rss('name'), for example.

Can filters even accept a 2nd argument? I thought that was only actions that could.

[tzafrir]

They accept a second argument in the same manner as actions,

add_filter('filtername', 'function', priority, argumentcount);

[Viper007Bond]

Ah, RTFM, huh? Heh.

Wondered why apply_filters('customfiltername', $var1, $var2) never worked for me...

[tzafrir]

What does that mean, invalid?

There is still no way to properly use this filter.

[tzafrir]

apply_filters() isn't passing a 2nd parm, so adding a 2 to add_filter() does nothing.

Reopening by advice of Viper007bond.
