->url on image not giving full path, only folder with no filename

[joer80]

When I do $page->BackgroundImage->url it gives the path without the filename.  Is that normal?  I was thinking it gives both.

If I do  $page->BackgroundImage->url . $page->BackgroundImage I can get it to show both.

What am I doing wrong?

Thanks!

I am not sure what is going on in your case (I am sorry I dont have an answer). However, $page->BackgroundImage->url should return the pull path to the image.

This is the usual array of images problem - either add first()->url, or set the image field to only accept one image.

[joer80]

That is what I would have thought also, but it is set to "Single Item (Null if empty)" with 1 as the max images.

Looks like it is returning an array no matter what I do.

Any chance you have output formatting turned off?

[joer80]

I do further down the page.  This is the flow.

addHookBefore (save)

      $event->message("background-image: " . $page->BackgroundImage->url);
     //Gives  background-image: /site/assets/files/1312/

addHookAfter (save)

     setOutputFormatting(false);

(save a different page)

Do a little experiment and dump or bd($page->of()); before your $event->message and see what you get.

[joer80]

var_dump($page->of()); doesnt seem to do anything.

If I take off the "->of()" it will print out the page info.

[adrian]

Well, that's weird - here it returns true or false.

Anyway, we are getting off track. Either turn on output formatting before $event->message, or simply add first() before url and you should be fine. Does that work or not?

[joer80]

I was able to use output buffering and get it to: result: bool(false)

ob_start();
var_dump($page->of());
$result = ob_get_clean();
$event->message("result: " . $result);

I am in a module that is hooking before page save so maybe it would be best if I leave output format off?  I am wondering if processwire is expecting that?  

I dont mind treating it like an array as long as it is expected behavior and not a bug that will be fixed later!

Thanks for all your help!

[adrian]

It's not a bug - when saving, output formatting has to be off.

PS - you should get familiar with Tracy:

bd($page->of()) is a lot easier than messing around with ob_start and var_dump

[joer80]

Ok, thanks for the tip!

Actually, output formatting is always off in a module. If output formatting is off, Image fields will always return an array, no matter your settings. So...first(), last(), eq()....are your go to guys...

Only if it's executed before or after template rendering, which is most of the time, but not always. That's why I go with this in places, where I cannot be sure about the state of output formatting:

$page->getUnformatted('image')->first()->url
