Swiper.js ACF Gallery slider

You can create a simple Image slider with Swiper.js and ACF Gallery field. Here is the quick tutorial for that.

1. Create ACF Gallery field and set the ACF field to Return the Image ID
2. Add Images
3. Embed the Swiper.js
4. Add a code for Swiper initialization

Create ACF Gallery field and add images

Go to ACF, create a field group and add field type Gallery.

Add images to the field:

Prepare the Slider

You need to embed the swiper js and css. You can use the CDN or download and add to your FTP.

<link
  rel="stylesheet"
  href="https://cdn.jsdelivr.net/npm/[email protected]/swiper-bundle.min.css"
/>

<script src="https://cdn.jsdelivr.net/npm/[email protected]/swiper-bundle.min.js"></script>

I am using Advanced Scripts for that and load it from my theme folder:

Create the slider code and add it to the page or template (if you use Oxygen builder, use unwrapped code block).

<div class="swiper-container self--center">
    <div class="photo-slider swiper self--center">
        <div class=" swiper-wrapper">
            <?php
            $images = get_field('fotogalerie'); // ACF field slug
            $size = 'full'; // (thumbnail, medium, large, full or custom size)
            if ($images) : ?>
                <?php foreach ($images as $image_id) : ?>
                    <div class="swiper-slide slider-image">
                        <?php echo wp_get_attachment_image($image_id, $size); ?>
                    </div>
                <?php endforeach; ?>
            <?php endif; ?>
        </div>
    </div>
</div>

Add .JS code for slider initialization (customize it how you need with Swiper API):

const swiper = new Swiper('.photo-slider.swiper', {
    disableOnInteraction: false,
    slidesPerView: 1,
    centeredSlides: true,
    loop: true,
    // Responsive breakpoints
    breakpoints: {
        480: {
            slidesPerView: 2,
            spaceBetween: 15,
        },
        768: {
            slidesPerView: 2,
            spaceBetween: 25,
        },
        1366: {
            slidesPerView: 3,
            spaceBetween: 40,
        },
        1920: {
            slidesPerView: 4,
            spaceBetween: 45,
        }
    },
    autoplay: {
        delay: 1,
    },
    speed: 5000,

    grabCursor: true,
    // Navigation arrows
    navigation: {
        nextEl: '.swiper-button-next',
        prevEl: '.swiper-button-prev',
    },
});

Thats it, you are done.
