    Hey You Gays Filter

    Are you tired of people always saying ‘guys’ when they’re talking to a mixed gender group of people? I know I am. One weekend I got four (yes four) comments about my code saying “You guys should…” or “Ask the guys who …” and so on.

    All implied I wasn’t the human who wrote the code. Spoiler alert. I was. While I can’t fix the world out there, I do tend to reply with a handy gif:

    Eowyn from Lord of the Rings, pulling off her helm and shouting I AM NO MAN before killing a wraith and saving everyone.

    But I can fix MY site. Since I only need this for comments on my site (I’m in charge of how I write), I can use this:

    add_filter( 'comment_text' , 'hey_you_gays', 11 );
 
function hey_you_gays( $text ) {
    static $dblq = false;
      if ( false === $dblq )
        $dblq = _x('“', 'opening curly quote');
      return str_replace(
        array( ' guys', '‘guys', $dblq . 'guys', '> guys', '(guys' ),
        array( ' guys', '‘gays', $dblq . 'gays', '> gays', '(gays' ),
      $text );
}

    If you need to use it in titles and post content, steal the code from capital_P_dangit(). After all, that’s what we do.

  • Making Plugins Filterable

    Making Plugins Filterable

    I’m really bad at thsi since, generally, I don’t know why people would want to with the plugins I make. Which means I don’t do it. Which means I didn’t know how.

    I have a plugin that records the IP address of users as they register and outputs it on the ‘show users’ page. It’s simple and it works.

    Someone asked me if I could make it link to a place where he could see where the IP was from. Now my intent with the plugin was to list the IPs so I could spot serial sock puppets. But this use-case, I agreed, was valid. I just didn’t want to tie my plugin into one service or another. So I made it filterable.

    As it happens, it was incredibly simple. This is filed under “Stuff I should have known years ago…”

    Make The Output Filterable

    Originally I had the code outputting $theip and, in order to make it filterable, I wrapped that with this:

    if ( has_filter('ripm_show_ip') ) {
    $theip = apply_filters('ripm_show_ip', $theip);
}

    The whole function looks like this:

    	public function columns($value, $column_name, $user_id) {
        if ( $column_name == 'signup_ip' ) {
            $ip = get_user_meta($user_id, 'signup_ip', true);
            if ($ip != ""){
                $theip = $ip;
				if ( has_filter('ripm_show_ip') ) {
					$theip = apply_filters('ripm_show_ip', $theip);
				}
                return $theip;
            } else {
                $theip = '<em>'.__('None Recorded', 'register-ip-multisite').'</em>';
                return $theip;
            }
        }
	    return $value;
	}

    You’ll notice the has_filter() check is only on one possible output? That’s because I’m translating the output on the other one, which says “None Recorded” I could filter that, so people could change it to anything they want, but right now I think that’s a bit odd.

    Filter The Output

    To test this, I made a file /mu-plugins/register-ip-multisite.php and put the following inside:

    function filter_ripm_show_ip($theip) {
    $theip = '<a href="https://duckduckgo.com/?q='.$theip.'" target="new">'.$theip.'</a>';
    return $theip;
}
add_filter('ripm_show_ip', 'filter_ripm_show_ip');

    That made it a link. Simple.

    Does It Work?

    Of course!

    Example of users screen with the IP showing as a link

    I did not apply the filter to the output on the edit-users page, but if that turns out to be needed, I can.
