Cannot access protected property Concrete\Core\File\File::$fID

Permalink
Hi there,

I want to place a background on my page, comming from an attribute. <5.7 I did it with the following code:
<?php 
$c = Page::getCurrentPage();
$pl = $c->getCollectionAttributeValue('achtergrond');
   $pv       = File::getByID($pl->fID);
   if (empty($pl)) {
    $image_url    = $this->getThemePath()."/images/banner.png";
   } else {
   $image_url    = $pv->getRelativePath();
}
       ?>

Now I get the error

Cannot access protected property Concrete\Core\File\File::$fID

Does anybody know what to do? Thanks!

Change
$pl->fID


to:
$pl->getFileID();

Although, I'm not sure whether you even need that.

Your example does not specifically explain what type of an attribute the 'achterground' is but if it's already a file attribute, the line that says:
$pv = File::getByID($pl->fID);


is completely unnecessary.

You could use the $pl variable straight away if it's already a File object.

Yes it is a file attribute. 'achtergrond' is dutch for 'background'. The following code is working like a charm:

$pl = $c->getCollectionAttributeValue('achtergrond');
   if (empty($pl)) {
    $image_url    = $this->getThemePath()."/images/banner.png";
   } else {
   $image_url    = $pl->getRelativePath();
}


So thanks a lot!

AFAIK, you even don't need to define $c (if you're on a theme).
But yeah, mainio is correct. If the page attribute is a file type, then you have the image object already, and you can get the the relative url straight off of it.
