PHP Question

wordpress custom excerpt length not working

I have this code in my functions.php

function custom_excerpt_length() {

return 15;

}

add_filter('excerpt_length', 'custom_excerpt_length');


but it doesn't work as it gives me the full text and not the 15 words I specified. And the grid I have set up on my website is not right because of this.

my movie grid

Thanks in advance

Answer

Also use this code for multiple type of getting excerpt

function excerpt($limit) {
      $excerpt = explode(' ', get_the_excerpt(), $limit);
      if (count($excerpt)>=$limit) {
        array_pop($excerpt);
        $excerpt = implode(" ",$excerpt).'...';
      } else {
        $excerpt = implode(" ",$excerpt);
      } 
      $excerpt = preg_replace('`\[[^\]]*\]`','',$excerpt);
      return $excerpt;
    }

    function content($limit) {
      $content = explode(' ', get_the_content(), $limit);
      if (count($content)>=$limit) {
        array_pop($content);
        $content = implode(" ",$content).'...';
      } else {
        $content = implode(" ",$content);
      } 
      $content = preg_replace('/\[.+\]/','', $content);
      $content = apply_filters('the_content', $content); 
      $content = str_replace(']]>', ']]>', $content);
      return $content;
    }

then in your template code you just use..

<?php echo excerpt(25); ?>
