Answered Get value to retrieve images from articles resource container. Resizing the image with phpThumbOf - Bob Ray's snippet

Quote from: BobRay at May 18, 2012, 01:51 AM

OK, that should make it somewhat easier. If all articles had an image, you could use getResources, but it sounds like that's not the case so you'd have to roll your own. I'm making some guesses here (e.g., that the TV contains a path to the image) -- something like this (untested):

Put this tag in where the image path goes:

[[!getArticleImage]]

Then create a snippet called getArticleImage:

<!--?php
/* getArticleImage snippet */

$c = $modx--->newQuery('modResource');
$c->where(array(
    'hidemenu' => '1', 
    'published' => '1'
));
$c->sortby('publishedon','DESC');
$c->limit(10);

$resources = $modx->getCollection('modResource', $c);

foreach($resources as $resource) {
    $imagePath = $resource->getTVValue('name of image TV here');
    if (!empty($imagePath)) {
         return $imagePath;
    }

}

return 'path_to_some_default_image';

This code (if it works) will check the 10 most recent articles for an image and return the first one found. It will also pull non-article resources that are published and hidden from menus, but there shouldn't be very many of them and they won't have the image TV filled so it will skip them. You can change the limit() number to search more or fewer articles.

Hello! I tried Bob's snippet and it works fine. How can I use phpThumbOf on the snippet to resize the TVvalue instead of outputting a full sized image?

Thanks in Advance. [ed. note: nunofil last edited this post 10 years, 10 months ago.]

Thank you bblinda and Bob.

I tried:



... but I get the same result, as before, no image resize, just the full sized one, I also cleared the cache.
Don't know I what I'm doing wrong? [ed. note: nunofil last edited this post 10 years, 10 months ago.]

Check the spelling of phpThumbsUp against the name of the snippet. I think it's phpthumbsup.

I've tried pThumb (I couldn´t find thumb Plus, probably is this pThumb) but I get this output(error) on the frontend of the site:




Using this:


Its working now. I changed the base url . Thank you both, for pointing me in the right direction. [ed. note: nunofil last edited this post 10 years, 10 months ago.]
