image size: fatal error

[reems]

Hi,

I have the following php lines in a template:

$top10 = $pages->find("template=hotel, top10>0,sort=-top10");
foreach($top10 as $top) 
  {
  echo "<li><a href='{$top->url}'>{$top->title}</a></li>";
  $image = $top->foto_upload->first();
  $thumb = $image->size(100, 100); 
// if($image) echo "<img src='$image->url'>";
  }

The last (for the moment commented) line works fine and shows one image but too big. Before showing the image I want to resize it.

But the line "$thumb =$image->size(100, 100);" throws the following error:

Fatal error: Exception: Method Pagefile::size does not exist or is not callable in this context (in /home/travelinlu/domains/travelinluxury.nl/public_html/wire/core/Wire.php line 320) in /home/travelinlu/domains/travelinluxury.nl/public_html/index.php on line 216

Reading the forum on such errors gives me no clear solution. Most of the time the answer is, that the function is called on an image array, but in this case (after using first() ) it is clear just one image I want to resize.

"foto_upload" is (afcourse) an Image field and I use PW 2.4.

Anyone with a solution??

Thanks,

Try

$image->of(true); just before resizing...

I think you have file field instead of image field.

Good catch Antti!

How stupid of me, indeed, it was still a File field instead of an Image field. Thanks Apeisa.

Now it works as it should be.

But, Kongondo, could you explain your solution: $image->of(true); ?

I can't find it in the API and I'm curious what is does.

Btw, that did not work, I got this error:

"Method Pageimage::of does not exist or is not callable in this context"

Thanks!

By default, output will be formatted according filters you may have defined with the field. If you are modifying the values of a page's custom fields, you will need to call $page->setOutputFormatting(false) before doing so. This turns off output formatting, which ensures that saved values don't already have runtime formatters applied to them. ProcessWire will throw an error if you attempt to save formatted fields.

See the cheatsheet. Usually you use this to change values on pages and save them through the API.

I don´t know why to use it here. Kongondo might explain that

Setting ->of(), and the image field will always be an array, no matter what the maxFiles is set to.

( was maybe better if Ryan wasn't that nice for the single image and it would always be an array )

Yep, what Martijn said or read here from the Reiska himself

Thanks guys for stepping in!

Slapped my forehand a few times with that one
