Image Object of file in assets

The CMS Questions

hi,
i’m using lingonberry template and i want to add a feature to display a default image, if there is no cover image selected on a specific page template.

the snippet for the coverimage looks like this:

<?php if($image = $item->coverimage()->toFile()) : ?>
<div class="featured-media">
  <a href="<?= $item->url() ?>">
    <img src="<?= $image->resize(766, null, 85)->url() ?>" rel="bookmark" title="<?= $item->title()->html() ?>"<?php e($image->alt()->isNotEmpty(), ' alt="' . $image->alt()->html() . '"') ?>>
    <?php if($image->caption()->isNotEmpty()) : ?>
    <div class="media-caption-container">
      <p class="media-caption">
        <?= $image->caption()->html() ?>
      </p>
    </div>
    <?php endif ?>
  </a>
</div>
<?php endif ?>

My Problem: when i want to load a default image via:

<?php
if(!$image = $item->coverimage()->toFile())  {
$image = kirby()->roots()->assets() . '/images/defaults/traildefault.jpg' ;
}
?>

i just add the string of the imagefile location to the variable $image and i can’t use things like $image->resize(766, null, 85)->url()

as far as i understand, the problem is, that $image = $item->coverimage()->toFile() generates an object, that is not the same as a string of path to file.
so, i think i need to generate such an object of the “external” image, like it is done with the image of the field.

how to do so?

thx in advance

To get an image object from an asset file you can try this (untested, but from this post):

<?php $image = new Asset('assets/path/to/default.jpg') ?>

hi,
thx a lot.
I just gave it a try and get error Call to undefined method Asset::alt()
on this line:

<img src="<?= $image->resize(766, null, 85)->url() ?>" rel="bookmark" title="<?= $item->title()->html() ?>"<?php e($image->alt()->isNotEmpty(), ' alt="' . $image->alt()->html() . '"') ?>>

This happens because Assets don‘t have a meta .txt file where additional file field content can be stored. The same will happen with $image->caption().

I would try something like this …

<div class="featured-media">
  <a href="<?= $item->url() ?>">
    <?php if($image = $item->coverimage()->toFile()) : ?>
      <img src="<?= $image->resize(766, null, 85)->url() ?>" rel="bookmark" title="<?= $item->title()->html() ?>"<?php e($image->alt()->isNotEmpty(), ' alt="' . $image->alt()->html() . '"') ?>>
      <!-- ... and so on -->
    <?php else: ?>
      <!-- load image from assets and add alt and caption text on your own -->
    <?php endif; ?>
  </a>
</div>

maybe i can work with that. thx a lot.

the question is just a start of editing this snippet. i want to do many things with the image. for example overlaying a watermark. (already got a solution on this)

it seems i found a better solution. i created a new page at site-root which will hold all images i want to call from other pages.

like this:
$image = page('defaultimages')->image('traildefault.jpg');
