News Manager

[fabsn]

hi there.
i use the excerpt function to shorten news on the overview page. i now want to add a link which links to the full version (as the headline already does). Something like a linked [read more] instead of just [...] plain text

i tried something by adding the following in the function nm_show_post (site.php)

Code:

...
<div class="nm_post_content"><?php echo $content; ?></div>
      <?php
      
          echo '<a href="';
        echo $url;
        echo '">read more</a>';
        
      # print tags, if any
      if (!empty($post->tags)) {
...

this causes the correctly linked text under every news excerpt, but also at the end of every news itself.

i then tried to add some code in the function nm_create_excerpt (functions.php)

Code:

/*******************************************************
* @function nm_create_excerpt
* @param $content the post content
* @return a truncated version of the post content
*/
function nm_create_excerpt($content) {
  global $NMEXCERPTLENGTH;
  $len = intval($NMEXCERPTLENGTH);
  $content = strip_tags($content);
  $url     = nm_get_url('post') . $slug;

  if (strlen($content) > $len) {
    if (function_exists('mb_substr'))
      $content = trim(mb_substr($content, 0, $len, 'UTF-8')) . ' [<a href="'. $url . '">read more]</a>';
    else
      $content = trim(substr($content, 0, $len)) . ' [...]' . $url;      
  }
  return "<p>$content</p>";
}

this adds the link ".../index.php?id=blog&post="
but the last part of the url is missing.

Could somebody help me with this? Thanks in advance
