Ditto call - trunc introtext

    Hello,

    I’m searching how to trunc a introtext [+summary+] from a chunk like this:


    <div id="tpl-image-div2"><img src="[+tvimage_220-170+]" width="220" height="170" align="left" /> </div>
    <div id="tpl-image-div3"><a href="[~[+id+]~]">[+title+]</a></div>
    <div id="tpl-image-div4">[+tvauteur_n1+], le [+date+]</div>
    <div id="tpl-image-div5"> [+summary+]... </div>
    </div>

    I’ve tried with PHx, Ditto (&truncOffset, &truncLen) - no luck !

    My ditto call:
    [!Ditto? &tpl=`tpl-menu-image` &parents=`41` &display=`1` &extenders=`summary` &trunc=`true` &truncOffset=`15` &truncLen=`120`!]

    Does anybody have a solution or a snippet call that work ?

    Thanks for you help
    Mehdi

      I don’t think that Ditto has an ability to truncate/shorten its placeholders. The shortest way (not necessarily simpliest) is a creation of your own snippet to handle such a shortening. Here goes an idea of such a snippet. Suppose, we name it "truncate", its code may look like:
      /* ----------
parameters:
$what - text to shorten
$len - desired length of the shortened text
   ---------- */
if (strlen($what) > $len) {
  /* there is a point to truncate */
  $what = preg_replace('/^(.{' . $len . ',}? ).*$/is', '$1', $what) . '...';
}
return $what;

      Then the part of your template relating to [+summary+] should look like:
      <div id="tpl-image-div5">[[truncate? &what=`[+summary+]` &len=`80`]]</div>

      The above-presented code of the snippet is merely an idea of it. The shortening is done via regular expression that takes at least $len characters (80 in an example) and truncates at the first space met.

          Another alternative would be to use ditto’s built in PHx features to truncate the field. Here is some info on PHx:
          http://wiki.modxcms.com/index.php/PHx

          You can use PHx in a Ditto Tpl by setting &phx=`1` in the Ditto call:

            Something is happening here, but you don&#39;t know what it is.

              hi,

              this truncate snippet is cool, but his should not be necessary as Ditto is supposed to be able to truncate into its summary pl , but it seams absolutely out of order ( however its doc is clear: http://ditto.modxcms.com/extenders/summary.html )
