![]() Step 4: Create Gallery page with Views module Next, click to "manage display" next Gallery content typeĪfter this step, you'll need to add some demo content (go to your_site/node/add/gallery). On image gallery field settings, scroll to "Number of value" and choose "Unlimited". Click "Create new style" and add "Scale and Crop" effect, fill 150 in with, and 150 in height.Īfter create content type, go to Structure -> Content Types and click to "manager fields" next Gallery content typeĭelete body field and add new "Image Gallery" field. This is pretty simple, just follow the prompts and fill in the fields.įrom admin toolbar, go to Configuration -> Image Styles (your_site/admin/config/media/image-styles), add new style name "gallery-thumb". ![]() Go to Structure -> Content Types (/admin/structure/types) and add a new content type called Gallery (remember this machine name for step 5). Not sure? you can read installation guide here) and the views module. Requirementsįor this tutorial you will need to install Drupal 7 (because this tutorial for Drupal 7. ![]() Yes, you can use any theme you want.ĭemo for this tutorial here. Through the tutorial I'm going to show you how to create an image gallery page on Bartik (Drupal's default theme) theme. I will show you how to create a gallery page that you could easily modify or customize. Remember though to inject the entity type manager if you are in such a context that you can.Create an image gallery in Drupal is not difficult, you can use some modules but they're often more than you need and sometime difficult to tweak. You now have the image URL which will generate the image upon the first request. $url = $style->buildUrl('public://my-image.png') This would render the image tag with the image having been processed by the style.įinally, if we just want the URL of an image with the image style applied, we need to load the image style config entity and ask it for the URL: $style = \Drupal::entityTypeManager()->getStorage('image_style')->load('thumbnail') So to render an image with a particular image style, we need to do the following: $render = [ What we should do is always return render arrays and expect them to be rendered somewhere down the line. Second of all, in Drupal 8 we no longer (should) call theme functions like above directly. This means they are created and exported like many other things. ![]() It may not yet exist, but on the first request, it would get generated.įirst of all, image styles in Drupal 8 are configuration entities. ![]() The function it uses internally for preparing the url of the image is image_style_url() which returns the URL of the location where the image is stored after being prepared. The theme prepares the URL for the image, runs the image through the style processors and returns a themed image (via theme_image()). You'll see this pattern all over the place in Drupal 7 codebases. In Drupal 7, rendering images with a particular style (say the default "thumbnail") was by calling the theme_image_style() theme and passing the image uri and image style you want to render ( some other optional parameters): $image = theme('image_style', array('style_name' => 'thumbnail', 'path' => 'public://my-image.png')) In this article we are going to look at how we can render images using image styles in Drupal 8. ![]()
