Code to automatically create more-tag or excerpt.

    Hi, is there some code/plugin which creates excerpts or more <more-tag>s (and auto-summaries) from Posts?
    I have thousands of Posts to import from old CMS, so doing this manually is not possible. I think this is a fairly common task, so I hope there’s already some plugin/hack available.

  • You can do this by calling the_except() function. It must be called inside the wordpress loop.

    If you want to automatically append a string such as “Read more…” for each excerpt you have called, it can be achieved by using add_filter function in wordpress.

    Ex. 

    <?php
    function addReadMoreToExcept(){
        global $post;
        $post_excerpt = get_the_excerpt( $post->ID );
        $readMore_permalink = get_the_permalink( $post->ID );
        $readMore_format = "[Read More...]";
        $readMore = sprintf( "%s %s", $post_excerpt,$readMore_permalink, $readMore_format  )
        return $readMore;
    }
    add_action('the_except', 'addReadMoreToExcerpt');

   /** Code not tested **/
?>

    Something like that.

    Thanks
