Laravel photo gallery with Alpine.js – Image is not fully displayed after clicking the thumbnail
To create a Laravel photo gallery with Alpine.js, you can follow the steps below:
-
Install Laravel and Alpine.js: First, make sure you have Laravel installed on your local machine or server. Then, install Alpine.js by adding it to your
app.scss
orapp.css
file:@import 'alpinejs';
Or, add it to your
webpack.mix.js
file:require('alpinejs');
-
Create a new controller for the photo gallery: Create a new controller called
PhotoGalleryController.php
in theapp/Http/Controllers
directory:namespace App\Http\Controllers; use Illuminate\Http\Request; class PhotoGalleryController extends Controller { public function index() { $photos = ['photo1.jpg', 'photo2.jpg', 'photo3.jpg']; // Replace with your actual photo paths return view('photo-gallery.index', compact('photos')); } }
-
Create a new view for the photo gallery: Create a new file called
index.blade.php
in theresources/views/photo-gallery
directory:@extends('layouts.app') @section('content') <div x-data="{ currentImage: '{{ asset('images/photo1.jpg') }}' }"> <div class="gallery"> @foreach ($photos as $photo) <img src="{{ asset($photo) }}" alt="Photo" @click="currentImage = '{{ asset($photo) }}'"> <div class="thumbnail"> <img src="{{ asset('images/thumbnail-' . pathinfo($photo, PATHINFO_FILENAME) . '.jpg')) }}" alt="Thumbnail" @click="currentImage = '{{ asset($photo) }}'"> </div> @endforeach </div> <img src="{{ currentImage }}" alt="Current Image"> </div> @endsection
Make sure to replace
'{{ asset('images/photo1.jpg') }}'
with the actual path to your first photo in thex-data
attribute. Also, make sure to create athumbnail-*
image for each photo and place them in thepublic/images
directory. -
Create a new route for the photo gallery: Add the following line to your
routes/web.php
file:Route::get('/photo-gallery', 'PhotoGalleryController@index')->name('photo-gallery');
-
Test the photo gallery: Start your Laravel server and visit
http://localhost/photo-gallery
in your web browser. Click on a thumbnail to see the corresponding full-size image.However, you may notice that the full-size image is not fully displayed after clicking the thumbnail. This is because the image is being loaded asynchronously, and the thumbnail's
click
event handler is executed before the full-size image has finished loading. To fix this, you can use Alpine.js'sintersectionObserver
to detect when the full-size image is in the viewport and then set thecurrentImage
variable accordingly. -
Update the view for the photo gallery: Update the
index.blade.php
file as follows:@extends('layouts.app') @section('content') <div x-data="{ currentImage: '{{ asset('images/photo1.jpg') }}' }"> <div class="gallery"> @foreach ($photos as $photo) <img src="{{ asset($photo) }}" alt="Photo" @click="showImage(this)"> <div class="thumbnail"> <img src="{{ asset('images/thumbnail-' . pathinfo($photo, PATHINFO_FILENAME) . '.jpg')) }}" alt="Thumbnail" @click="showImage(this)"> </div> @endforeach </div> <img x-show="currentImageShown" src="{{ currentImage }}" alt="Current Image" x-on:intersection="currentImageShown = true"> </div> @endsection <script> document.addEventListener('alpine:init', () => { Alpine.data('gallery', () => ({ showImage(el) { this.currentImage = el.src; } })); }); </script>
This updated code uses Alpine.js's
intersectionObserver
to show the full-size image only when it is in the viewport. ThecurrentImageShown
variable is set totrue
when the image is in the viewport, and the full-size image is displayed using thex-show
directive.With these changes, the full-size image should now be fully displayed after clicking the thumbnail.
