post carousel – limit the words in post entry summary

This option is available only in the premium version of the plugin.

With the free version, you can accomplish the same by overriding the WP hook/filter named ‘lae_posts_grid_entry_excerpt’.

There are number of examples of how to use filters here – https://gist.github.com/live-mesh/90a79048686651fa0bfbf0eb40493611 and the above mentioned filter is available at includes/widgets/portfolio.php line number 929.

hi,
now i have limit the words in excerpt with:

add_filter('lae_posts_carousel_entry_excerpt', 'mytheme_restrict_excerpt', 10, 1);

function mytheme_restrict_excerpt($excerpt) {

    $excerpt = '<div class="entry-summary">';

    $length = 170; // ......

How can i add a “read more button”? it didn’t work with (see link below) because of limit the excerpt, the button is affected.

You can just append the read more button to the excerpt like below –

add_filter('lae_posts_carousel_entry_excerpt', 'mytheme_restrict_excerpt', 10, 1);
function mytheme_restrict_excerpt($excerpt) {
    $excerpt = '<div class="entry-summary">';
    $length = 120; // number of characters without breaking the words
    $append = '...';
    $string = get_the_excerpt();
    $string = trim($string);
    if(strlen($string) > $length) {
        $string = wordwrap($string, $length);
        $string = explode("\n", $string, 2);
        $string = $string[0] . $append;
    }
    $excerpt .= $string;
    
    $read_more_text = __('Read More', 'livemesh-el-addons');
    $excerpt .= '<div class="lae-read-more">';
    $excerpt .= '<a class="lae-button" href="' . get_the_permalink($post_id) . '">' . $read_more_text . '</a>';
    $excerpt .= '</div><!-- .lae-read-more -->';
    
    $excerpt .= '</div><!-- .entry-summary -->';
    return $excerpt;
}

Thank you, works fine.
