php - Next Previous Post in wordpress -

how can show content in next previous post of wordpress. example. next post link title there, possible show content of post (100 words).

       <div class="alignleftfp">         <?php next_post_link('%link', '%title'); ?> <?php get_next_post();?>         </div>         <div class="alignrightfp">         <?php previous_post_link('%link', '%title'); ?> <?php get_previous_post();?>         </div> 

much appreciated if response. . .

if it's within loop, can use the_excerpt() or get_the_excerpt() depending on requirements.

if it's outside loop, can use function post excerpt post id:

function get_excerpt_by_id($post_id){     $the_post = get_post($post_id); //gets post id     $the_excerpt = $the_post->post_content; //gets post_content used basis excerpt     $excerpt_length = 35; //sets excerpt length word count     $the_excerpt = strip_tags(strip_shortcodes($the_excerpt)); //strips tags , images     $words = explode(' ', $the_excerpt, $excerpt_length + 1);      if(count($words) > $excerpt_length) :         array_pop($words);         array_push($words, '…');         $the_excerpt = implode(' ', $words);     endif;      $the_excerpt = '<p>' . $the_excerpt . '</p>';      return $the_excerpt; } 

hope helps!
