Get latest item of images array

[Manaus]

Hello, 

I added a crop image field in the user template, and set the field to accepting 1 file only. I upload the image via the front end using these values:

     $a->setMaxFiles(1);
     $a->setOverwrite(true); 

Now, if I upload an image via the back end or the front end, the image field keeps many images. 

This resolves in a code trouble: if I try to print $page->createdUser->image->getThumb('micro') I get a string: the first image, but I need the last one. Btw printing $user->image I get an array, but it’s not what I need. Tried of course $page->createdUser->image->last()->getThumb('micro'), but returns an error "Pageimage::last does not exist or is not callable in this context"

Thanks for any suggestion...!

I think you might need to do something like this:

$users->get($page->createdUser->name)->image->last->getThumb('micro');

You need to get the name of the createdUser of the current page and get that user's fields from $users.

As for the issue of keeping multiple images - those settings won't work on the front end - you need to delete all existing images before uploading. See this post from Ryan: http://processwire.com/talk/topic/4267-creating-new-page-in-combination-with-a-file-upload/?p=41876

Hope that helps.

Thanks Adrian.

I can't find last in the documentation, just last() (which is behaving differently, as it seems)

Any hint where I can look?

Thanks!

Manaus - my mistake, it should be last(). Please let us know what happens when you try:

$users->get($page->createdUser->name)->image->last()->getThumb('micro');

They are the same. Like with first, child or children. Both version can be used. They're for convenience.
