add image tags to upload

[pmichaelis]

Hey,

I would like to add tags to an image field upload via api. Does anybody have some information on that?

im using the following code to update images on a page. 

# remove images
if(count($page->images)) {
  $page->images->deleteAll();
  $page->save();
}

# upload images
foreach($product->image as $image) {
  $page->images->add($image->url);
  $page->images->tags = ? // not working
}

$page->save();

During Page Update the backend says:
Session: Item 'tags' set to ProcessWire\Pageimages is not an allowed type

Thanks for help.

Hi, if I'm not mistaking, the tags are added to the image:

# upload images
foreach($product->image as $image) {
  $image->tags = "tag1 tag2";
  $page->images->add($image); //assuming $image is already a PageImage?
}

The imagefield itself can only be used to query the tags of the images then:

//e.g.
$page->images->findTag('tag1');    

Hope this helps

Hey Sebii,

thanks for your help, but I could not figure it out.

foreach($product->image as $image) {
  $image->tags = "tag1 tag2";
  $page->images->add($image->url);
}

$product->imgae is an external array of images. It has nothing to do with the page images. So there is nothing like $image->tags.

foreach($product->image as $image) {

$page->images->append($image->url);

$page->images->last()->tags = "tag1 tag2";

}

Hi sorry, it looked like it is already coming from a different imagefield.

foreach($product->image as $image) {
  $pageimage = new PageImage($page->images, $image->url); 
  $pageimage->tags = "tag1 tag2";
  $page->images->add($pageimage);
}

Edit: Woops, too slow and too much fiddeling. See the answer above...
