Google plus profile link from byline

If you only have one author, then you can add the following to your functions.php:

add_filter( 'tc_author_meta', 'my_author_meta');
function my_author_meta() {
	return sprintf( '<span class="author vcard"><a class="url fn n" href="%1$s" title="%2$s" rel="author">%3$s</a></span>' ,
		esc_url( 'https://example.com' ),
		esc_attr( sprintf( __( 'Follow %s on Google+' , 'customizr' ), get_the_author() ) ),
		get_the_author()
	);
}

Change https://example.com and “Follow … on Google+” to the correct link / phrase. Leave the %s as it is, because it is substituted with the user’s name.

If you have more than one user, then you would need to add some programming logic along the lines of joe's link = something.com, jane's link = something else.com; if joe, then $google_link = joe's link; elseif jane, then $google_link = jane's link; esc_url( $google_link ) (this is psuedo code / I’m paraphrasing — don’t add to functions.php).

Thank you sir, it is the information what exactly I wanted. I worked for me.
