Shorten excerpts option has bug (with fix)

I have found a slight bug with the “Shorten excerpts” option.

When selecting the “Shorten to closest space/period” options the result is that this always happens to the excerpt even though the excerpt length is less than the value given in the “Excerpt length” option.

The fix is to alter the scu_element2() function in the lib.php plugin file as follows.

//excerpt
function scu_element2() {
    global $post, $scu_layout, $scu_sc;

    $l      = scu_val('excerptlength', $scu_layout);
    $filter = scu_val('filter', $scu_layout);

    //if (strlen($post->post_excerpt) > 1){
    //  $t = $post->post_excerpt;
    //}else{
    //$t = $post->post_content;
    //}

    //main content field, strip all tags
    if ($filter == 1 or $filter == '') {
        $t = strip_shortcodes(strip_tags($post->post_content));
    }
    //excerpt field, strip all tags
    if ($filter == 2) {
        $t = strip_shortcodes(strip_tags($post->post_excerpt));
    }
    //meta data, full html
    if ($filter == 3) {
        $custom = get_post_custom($post->ID);
        $t      = $custom['text'][0];
       //	$t = str_replace("\n", "<br />", $t);
    }
    //show with full html
    if ($filter == 4) {
       //warning apply filtersaddfilters outside $t, but is needed on the postpage
       $t = apply_filters('the_content', $post->post_content);
       //  $t = strip_shortcodes(strip_tags($post->post_content));
       // $t = strip_shortcodes($post->post_content);
       // $t = $post->post_content;
       //									$t = str_replace("\n", "<br />", $t);
    }
    //excerpt field, full html
    if ($filter == 5) {
        $t = $post->post_excerpt;
    }

    //shorten to period
    if ($filter < 3) {

        if (strlen($t) > $l) {
            $cont   = '...';
            $period = scu_val('excerptshorten', $scu_layout);

                                            //period shorten
            if ($period == 1) {
                $p = strrpos(substr($t, 0, $l), '.');
                if ($p > 0 and $p < $l and $l > 0) {
                    $l    = $p + 1;
                    $cont = '';
                }
            }
                                            //space shorten
            if ($period == 2) {
                $p = strrpos(substr($t, 0, $l), ' ');
                if ($p > 0 and $p < $l and $l > 0) {
                    $l = $p + 1;
                    //$cont = '';
                }
            }

            //shorten
            if (strlen($t) > $l and $l > 0) {
                $t = substr($t, 0, $l) . $cont;
            }
        }
    }

    //add a read more link
    $pe = scu_val('postexcerpt', $scu_layout);
    if ($pe > 0) {
        $l  = get_permalink($post->ID);
        $cl = 'scu-readmore';
        $t .= ' <a class="' . $cl . '" ' . $style . '  href="' . $l . '">Read more</a>';
    }

    return scu_div($t, 'scu-excerpt-layout' . $scu_layout, 2);
}
