Check if image has tags saved

[suntrop]

The documentation is a little short on this topic … there seems to be only a getTag() and findTag()

No way to check if there is a tag at all? The hasTag() method seems to be not allowed on image fields.

I want to use an existing image field (something like WordPress’s featured image/post thumbnail) to gather images for a gallery as well.

Problem is …

<?php if(count($page->images)): ?>
	<img class="pull-right thumbnail" src="<?php echo $page->images->first->height(300)->url ?>" alt="">
<?php endif; ?>

… there are thousands of pages/images without any tags and I can’t tag them all with »featured« to use them as now. Thus I have to tell my template to only use the first image without a tag to use as the featured image.

Sounds complicated Hope you know what situation I am in

$tagless_images = new WireArray();
foreach ($page->images as $image) {
    if(empty($image->tags)) {
        $tagless_images->add($image);
    }
}

Now $tagless_images is a WireArray of images on the page that have no tag.

Edit: this is better...

$tagless_images = $page->images->filter("tags=''");

Thanks. It works

The filter method looks far better, but I need the tagged photos later on this page.
I tried this one 

<?php if(count( $page->images->has("tags=''") )): ?>

but it is always true, even if there are only images with tags.

Not sure what you mean; $tagless_images are your images without tags, for images with tags you use:

$mytag_images = $page->images->findTag('mytag');

I tried this one 

<?php if(count( $page->images->has("tags=''") )): ?>

but it is always true, even if there are only images with tags.

Count does not belong in your if expression: ->has() returns true or false so it doesn't make sense to count it.

filter() strips out all images without a tag. Those are not in $page->images after using filter()

[Robin S]

Okay, replace filter() with find():

$tagless_images = $page->images->find("tags=''");

[suntrop]

Well, that was simple  

Haven't thought of using find() behind images. Need to use PW more again.

Thanks!
