Image size problem when using first

[huseyin]

Hello,

i use PW 3.0.148 0n local XAMPP.

It works like this when i have single image field :
$page->image->size(z,y)->url

But as soon as i have multiple images field and add "first" or "first()" or "eq(0)" than i get no output.

ERROR : $page->image->eq(0)->size(z,y)->url 
WORKS : $page->image->eq(0)->url 

Can anybody reproduce this and find the reason?

How is your inputfield's formatted value configured? try setting it to be formatted as a single item.

I have 2 fields one is single item, the other is multiple items. 

With the single item field it works. But i need also the other multiple items field and with the multiple items field it should work also..

you need to check images count

if(count($page->images)) {
  // the page has one or more images
}

So sorry.

while checking i realized the field was "file" instead "image". Corrected this and it works now.

Sorry again and thank you for your effort.
