Secondary Image in Image Field

Recommended Posts

ZGD    10

I'm currently developing a site where some image fields need to be able to have two images associated with them, a thumbnail and a full sized image (which is often a different crop) which will be shown in a lightbox view.

This is fine for most templates, I'm just using normal image fields that return an array and support up to two images. If a second image is present in the field then it will be used as the alternative image for the lightbox. If only one image is present, it will be used for both thumbnail and full sized (the template resizes for the thumbnail using the API). However I have templates with flexible layouts using a repeater matrix, and one of the matrix types is an 'image grid'. This is an image field that supports an unlimited number of images, so obviously this method is not suitable here.

I've tried creating a repeater in this matrix type which contains an image field (each supporting two images, as above), but this means that I can no longer drag and drop multiple images at once. Each image in the grid has to be uploaded individually which is a big problem as there are many instances of these grids with a large number of images.

I've tried the ImageExtra module but it seems you can't add an image field as a secondary field.

Any suggestions as to how I might solve this problem?

Are you saying that an images field inside a repeater does not allow drag-and-drop uploading? I'm not aware of any such limitation and with a quick test it seems to be working for me, even inside nested repeaters.

I think you should check out the Croppable Image 3 module for managing your different crops.

Nope not quite, sorry I probably wasn't very clear there. Drag-and-drop does indeed work inside repeaters, my problem is that if I need to separate each image and its associated crop in the image grid into a separate repeater with an image field then I can't drag-and-drop say 20 images at once. I have to manually drag each image to the associated field in the repeater array.

An ideal situation would be the ability to store a secondary image with each image. For example each image has an input for alt text, I would somehow like there to be another input for another image. Essentially nested images.

CroppableImage3 is great but it also won't work for this as the images are prepared outside of PW as they have various other applications. The crops also aren't systematic and we also need to support the option for the crop being a completely different image entirely.

What you want the system to do is simply not possible with core features. Image fields are file storage fields and even the description for them is more of a convenience functionality rather than a good way to store information. I've not used ImageExtra by now, so I'm not sure how it does save it's additional data, but it seems it doesn't do what you need as well.

For such an image grid you should still go with single pages holding the image / thumbnail and additional info. Maybe you can use a pagetable to display those imagepages and keep the convenience of drag&drop / nice overview over items, which is not so nice with repeaters.

If this is the case, how does that go together with each/lots of those images having custom made thumbnails as well? It probably either going to be a lot of manual uploading work or you strip the feature of custom thumbnails. If both is not possible you probably wont get around building something custom to create those grids.

Thanks @LostKobrakai. That all makes sense.

I'd estimate less than 5% of images will have alternatives, so the manual uploading for those would be manageable. Being able to drag and drop multiple images at once is really the priority, but I had a better look through all the core modules earlier and decided the development time to create something custom probably wasn't worth it for this project. I looks like we will have to go with a repeater or pagetable approach as you've suggested.

      Hi all,
      PW: 3.0.42
      I'm trying to have responsive images in the body field. First I need to stop the image tag generated by CKEditor adding the width attribute to the image tag on insertion. I found the 'Skip width attributes on image tags?' in the settings of ProcessPageEditImage and that suggests it does exactly what I'm after.
      Sadly, even when this checkbox is checked and a new image is inserted the width attribute is still added.
      Am I missing something?
      TIA.

      A simple recursive function that walks over all image fields and those inside repeaters(including FieldtypeFieldsetPage) to find images tagged with a certain tag(s). It can easily be extended to file fields by changing instanceof FieldtypeImage to FieldtypeFile, or be restricted to file fields by adding a !$type instanceof FieldtypeFile, too. Adapted from ProcessPageEditLink::getFilesPage() method.
      /** * Find all images tagged with a certain tag in a page including repeater items. * * @param $page Page to search tagged images * @param $tag string|array Image tag(s). Can be 'foo' for single, 'foo|bar' for multiple OR tags, 'foo,bar' or ['foo', 'bar'] for multiple AND tags * @return array Tagged images in [basename => Pageimage] associated array form or empty an array */ function findTaggedImages(Page $page, $tag) { $tagged = []; foreach ($page->template->fieldgroup as $f) { $type = $f->type; if ($type instanceof FieldtypeImage) { /** @var Pageimages $images */ $images = $page->{$f->name}; if (!$images) continue; $tagged = array_merge($tagged, $images->findTag($tag)->getArray()); } else if ($type instanceof FieldtypeRepeater) { $items = $page->{$f->name}; if (!$items) continue; if ($items instanceof PageArray) { foreach ($page->$f as $item) $tagged = array_merge($tagged, findTaggedImages($item, $tag)); } // FieldtypeFieldsetPage returns a single page instead of a PageArray elseif ($items instanceof Page) { $tagged = array_merge($tagged, findTaggedImages($items, $tag)); } } } return $tagged; } And can be used as 
      $featuredImages = findTaggedImages($page, 'featured'); // get first featured image $featured = reset($featuredImages); // or array_shift($featuredImages)

      Hello,
      I have repeater field with an image field as one of its fields. It works correctly on all but one templates. I added an image, it shows the image uploading, but then the image just disappears and it doesn't save. What could it be ?
       
      Thanks

      Hi there,
      I'm looking to render some square images that are based on portrait originals. When the image is selected, I'll display it in portrait mode but when the images are in a "summary" mode, I want them square. What would be the best way to generate a square image from a portrait original? FYI, I would ideally prefer these images to based on IMG tags and not background images.
      Cheers!
