Resize getRandom() image

[derelektrischemoench]

Hi guys,

I'm trying to resize images which I query through getRandom(). I can't seem to get it right though. What I have so far is:

 

$randomImage = $pages->get($targetPageId)->images->getRandom()

Which returns an image, albeit in original resolution. I assumed I should be able to call resize() on the image like so:

$randomImage = $pages->get($targetPageId)->images->getRandom()->width(400)

Which unfortunately gives me an exception. I assume this is because getRandom() might not return an image but something else(?).

So how would I do this correctly?

 

Greetings

Look / debug what you get from ->images->getRandom(), maybe via die(var_dump($randomImage));

Then you will know what to do, or you come back with the new information and ask how to proceed further.

The function getRandom() returns null if the field is empty and not an empty object. You cannot call a function from null. You need to check first if the image object exists. Make also sure your selector $targetPageId includes only pages having a field 'images'. Try this:

$randomImage = !empty($pages->get($targetPageId)->images->getRandom())? $pages->get($targetPageId)->images->getRandom()->width(400) : null;
