5.7 page attribute

Permalink 2 users found helpful
I building a website where I would like to make page lists with thumbnail. This all fine, but I would like that set up several thumbnails for a page and when calling the page list display a certain thumbnail according to a checked attribute.
This was working perfectly in 5.6.X, but in 5.7 it give me an error like: "An unexpected error occured. File does not exist."
I figured out that I have to put all the thumbs attribute for each page on the list, no matter if has the boolean attribute or not, to avoid the error. I would like to set the thumbnails just where I need it not on every page.
Here is my code that worked well previously:
<?php 
defined('C5_EXECUTE') or die("Access Denied.");
$th = Loader::helper('text');
$ih = Loader::helper('image');
?>
<?php  foreach ($pages as $page):
      // Prepare data for each page being listed...
      $title = $th->entities($page->getCollectionName());
      $url = $nh->getLinkToCollection($page);
      $img = $page->getAttribute('webdesignthumb');
      $thumb = $ih->getThumbnail($img, 400, 281, true);
      $category = $page->getCollectionAttributeValue('webdesign');
      if ($category) { 
?>

Can you please provide the exact error that you are getting?

I believe that 
$img = $page->getAttribute('webdesignthumb');

returns the fileID not an actual file object, so you would need to do 
$fileID = $page->getAttribute('webdesignthumb');
if(intval($fileID > 0){
   $img = File::getByID($fileID);
   $thumb = $ih->getThumbnail($img, 400, 281, true);
}

The exact error is the one I wrote in the post, aka "An unexpected error occured. File does not exist."
Let me clarify a little bit. There is no problem with the file ID. The problem is that the page list controller try to pull thumbnail specified at the "webdesignthumb" attribute for all the pages in the location. But I have this thumbnail set only on pages when also the webdesign boolean attribute is present. And because there are pages without the "webdesignthumb" attribute it give me the above error (off course in some occasion the file does not exist since it wasn't specified).
My problem, or my question is that the code run perfectly on 5.6.x but not on 5.7.x. If you know what was changed in the page list module and how should I modify my code to work again?

I tried your suggestion and still got an error, different this time :)
The error is: An unexpected error occurred.
syntax error, unexpected '{'

I see your point, but still, the problem wasn't with the fileID. For example if I set the thumbnail "webdesignthumb" on every page the page list block is working fine. But this is not productive, since I will have 10 different thumbnail attributes and setting them on each page, regarding that I need it or not, is pointless.

I think I understand what you are saying, would it work right if you did this:

$category = $page->getCollectionAttributeValue('webdesign');
if ($category) { 
   $img = $page->getAttribute('webdesignthumb');
   ?>
   <article class="project"> 
          <a href="<?php  echo $url ?>" title="<?php  echo $title ?>">
      <?php 
      if($img){
         $thumb = $ih->getThumbnail($img, 400, 281, true);
         ?>
              <div class="thumb">
                     <img src="<?php  echo $thumb->src ?>" alt="" width="<?php  echo $thumb->width ?>" height="<?php  echo $thumb->height ?>" />
              </div>
      <?php } ?>
           <h2 class="project-title"><?php  echo $title ?></h2>

I figured out finally. Actually you where right about the fileID, and I can filter the page list without the other attribute (the boolean one). So the correct code is like this:
<?php  foreach ($pages as $page):
      // Prepare data for each page being listed...
      $title = $th->entities($page->getCollectionName());
      $url = $nh->getLinkToCollection($page);
      $fileID = $page->getAttribute('webdesignthumb');
      if(intval($fileID > 0)){
      $img = File::getByID($fileID);
      $thumb = $ih->getThumbnail($img, 400, 281, true);      
?>
<article class="project"> 
    <a href="<?php  echo $url ?>" title="<?php  echo $title ?>">
        <div class="thumb">
            <img src="<?php  echo $thumb->src ?>" alt="" width="<?php  echo $thumb->width ?>" height="<?php  echo $thumb->height ?>" />
        </div>
        <h2 class="project-title"><?php  echo $title ?></h2>

You missed a ')' first time, this is why it was giving the syntax error.
