How to shorten wordpress related posts title?

Hey ninopro,

thanks for reaching out – I’ll gladly help!
First go to “Plugins”->”Editor” and select WordPress Related Posts plugin in the upper right corner.
Then select the init.php file and replace the “function wp_rp_text_shorten($text, $max_char)” function with this one:

function wp_rp_text_shorten($text, $max_chars) {
	$shortened_text = mb_substr($text, 0, $max_chars - strlen(html_entity_decode(WP_RP_EXCERPT_SHORTENED_SYMBOL, ENT_QUOTES, 'UTF-8') + 2));
	$shortened_words = explode(" ", $shortened_text);
	$shortened_size = count($shortened_words);
	if ($shortened_size > 1) {
		$shortened_words = array_slice($shortened_words, 0, $shortened_size - 1);
		$shortened_text = implode(" ", $shortened_words);

	}

	return $shortened_text . WP_RP_EXCERPT_SHORTENED_SYMBOL; //'...';
}

After that find the line $output .= '<a href="' . $post_url . '" class="wp_rp_title">' . wptexturize($related_post->post_title) . '</a>';
and replace it with this one:
$output .= '<a href="' . $post_url . '" class="wp_rp_title">' . wp_rp_text_shorten(wptexturize($related_post->post_title),15) . '</a>';

You can change that number 15 (title length) to whatever suits you.

Let me know how it goes, take care and have a nice day,

Actually, it’s not quite working. It is shortening posts that only have about 14 characters and I have it set to 65. Surely if it’s under 65 it won’t need to shorten and yet there are posts well under 65 characters that are still being shortened unnecessarily?
