IMG_ASSIST: Teaser Thumbnail image --> Story Page Preview Size Image?

IMG_ASSIST: Teaser Thumbnail image --> Story Page Preview Size Image ?

Hello Drupal’ists….

Anyone know how to have a Story Teaser display the Thumbnail image, and then the Story Page for this Teaser, automatically display the larger Preview Size for this Image?

4.7.3, Using IMAGE module + IMG_ASSIST, Garland Theme

Thanks

Currently that's not possible, because img_assist works with the Drupal filter system and the output is cached. I've been thinking about changing img_assist (in a future version) to work with the nodeapi hook instead so that it could potentially do something like this (at the expensive of load time -- since output wouldn't normally be cached).

changing img_assist

thanks for the rapid reply... would be great to see this on a future IMG_ASST release...

This image behavior is effectively implemented currently in the IMAGE module, in the Image Gallery … performance overhead a small price to pay…

thanks, GARRY

imagecache

If you're not afraid of a little php, I'd recommend imagecache (http://drupal.org/project/imagecache) and a custom template for the story node type.

hook_nodeapi solution

Dave Cohen - February 6, 2007 - 17:41

I had the same problem and addressed it with hook_nodeapi, like so...

<?php
function custom_nodeapi(&$node, $op, $a3, $a4) {
  if ($op == 'view') {
    // For teasers, show thumbnails, not full images
    if ($a3) {
      //drupal_set_message("custom_nodeapi($op)" . dpr($node->teaser, 1));

      // modify the img tags inserted by img_assist
      $teaser = preg_replace('/<img src="([^"]*)\.([^\."]*)\.([^\."]*)" ([^>]*) class="image ([^"]*)"([^>]*)>/',
                             
                             '<img src="$1.thumbnail.$3" $4 class="image thumbnail" />',
                             $node->teaser);
      //drupal_set_message("new teaser: " . dpr($teaser, 1));
      $node->teaser = $teaser;
      
    }
    
  }
}
?>

Please elaborate

yogadex,

Can you elaborate briefly where you put that code and which variables are passed on to the function?

Thanks, riemann

Found the solution myself

There's a good description on how to use custom_nodeapi() on http://www.angrydonuts.com/the_nuisance_of_the_read_more_fl
Additionally, I slightly changed the code given above in order to make it work with my installation and I also got rid of the caption:

<?php
function custom_nodeapi(&$node, $op, $a3, $a4) {
  if ($op == 'view') {
    // For teasers, show thumbnails, not full images
    if ($a3) {
    
      // drupal_set_message("custom_nodeapi($op)" . dpr($node->teaser, 1));

      // modify the img tags inserted by img_assist
       $teaser = preg_replace('/<img class="image ([^"]*)" src="([^"]*)\.([^\."]*)\.([^\."]*)" ([^>]*) width="([^"]*)" height="([^"]*)" ([^>]*)>/',
                             '<img class="image thumbnail" src="$2.thumbnail.$4" $5 $8>',
                             $node->teaser);
                             
      // get rid of caption layer inserted by img_assist
       $teaser = preg_replace('/<span style="([^"]*)" class="caption">(.*?)<\/span>/',
                             '',
                             $teaser);                             
                                                          
      // drupal_set_message("new teaser: " . dpr($teaser, 1));
      $node->teaser = $teaser;
     
    }
   
  }
}
?>

Excerpt + Image assist

_carey - February 18, 2007 - 10:58

I just use the excerpt module with the image assist module. In the "teaser" area produced by the excerpt module I put a thumbnail image selected from image assist, and in the main body I make a separate selection and put a preview size image. Works great. No hassle.

Anyone know if this works

Anyone know if this works in 5.7? I can't get it to work, any ideas?

Drupal 5.7

By replacing $node->teaser" with "$node->content[body]['#value']" the above snippet worked for me in Drupal 5.7
