License

This is a commercial plugin licensed under the Craft License. It will be available on the Craft Plugin Store soon. See LICENSE.md for details.

⚠️ Pre-Release

This plugin is in active development and not yet available on the Craft Plugin Store. Features and APIs may change before the initial public release.

Quick Start

Get up and running with Slideshow Manager in 5 minutes:

1. Install the plugin

composer require lindemannrock/craft-slideshow-manager
./craft plugin/install slideshow-manager

2. Configure global settings (optional)

Go to Slideshow Manager → Settings in the Control Panel
Configure default Swiper behavior (navigation, pagination, autoplay, etc.)
Set CSS custom properties for styling

3. Add a field to your section

Go to Settings → Fields
Create a new "Slideshow Config" field (for per-entry config)
Add it to your entry type

4. Use in templates

{# Get config from entry field or use global defaults #}
{% set config = entry.slideshowConfig ?? craft.slideshowManager.settings.defaultSwiperConfig %}
{% set sliderId = 'slider-' ~ random() %}
{% set swiperConfig = craft.slideshowManager.buildSwiperConfig(config, sliderId) %}
{% set cssVars = craft.slideshowManager.buildCssVars() %}

{# Build slideshow - CSS/JS auto-loaded by plugin #}
<div class="swiper" id="{{ sliderId }}" style="{{ cssVars }}" data-swiper-config="{{ swiperConfig|json_encode|e('html_attr') }}">
    <div class="swiper-wrapper">
        {% for slide in entry.slides %}
            <div class="swiper-slide">
                {{ slide.content }}
            </div>
        {% endfor %}
    </div>

    {# Navigation/pagination if enabled #}
    {% if config.navigation %}
        <div class="swiper-button-prev swiper-button-prev-{{ sliderId }}"></div>
        <div class="swiper-button-next swiper-button-next-{{ sliderId }}"></div>
    {% endif %}

    {% if config.paginationEnabled %}
        <div class="swiper-pagination swiper-pagination-{{ sliderId }}"></div>
    {% endif %}
</div>

{# Initialize slider - simple one-liner! #}
{{ craft.slideshowManager.initSlider(sliderId) }}

That's it! Your slideshow is live. See Usage for more details and Examples for comprehensive use cases.

Installation

Via Composer

cd /path/to/project

composer require lindemannrock/craft-slideshow-manager

./craft plugin/install slideshow-manager

Using DDEV

cd /path/to/project

ddev composer require lindemannrock/craft-slideshow-manager

ddev craft plugin/install slideshow-manager

Via Control Panel

In the Control Panel, go to Settings → Plugins and click "Install" for Slideshow Manager.

Note: Frontend assets are pre-built and included. No build step required for installation.

Custom Swiper Installation

By default, the plugin auto-loads Swiper from CDN. However, you can use your own Swiper installation:

Option 1: Using npm (Recommended for Production)

1. Install Swiper via npm:

npm install swiper
# or
yarn add swiper
# or
pnpm add swiper

2. Import in your JavaScript:

// Your main JS file (e.g., src/js/app.js)
import Swiper from 'swiper';
import { Navigation, Pagination, Autoplay, EffectFade, EffectCube, EffectCoverflow, EffectCards, Grid } from 'swiper/modules';

// Import Swiper styles
import 'swiper/css';
import 'swiper/css/navigation';
import 'swiper/css/pagination';
import 'swiper/css/effect-fade';
import 'swiper/css/effect-cube';
import 'swiper/css/effect-coverflow';
import 'swiper/css/effect-cards';
import 'swiper/css/grid';

// Configure Swiper to use modules globally
Swiper.use([Navigation, Pagination, Autoplay, EffectFade, EffectCube, EffectCoverflow, EffectCards, Grid]);

// Make Swiper globally available
window.Swiper = Swiper;

Note: Only import the modules you need. Available modules include:

Navigation, Pagination, Scrollbar
Autoplay, EffectFade, EffectCube, EffectFlip, EffectCoverflow, EffectCards, EffectCreative
Grid, FreeMode, Thumbs, Parallax, Zoom
Keyboard, Mousewheel, HashNavigation, History, Controller, A11y, Virtual, Manipulation

See Swiper Modules Documentation for complete details.

3. Disable auto-loading in plugin settings:

Via Control Panel:

Go to Slideshow Manager → Settings → General
Disable "Auto Load Swiper CSS"
Disable "Auto Load Swiper JS"

Or via config file:

// config/slideshow-manager.php
return [
    'autoLoadSwiperCss' => false,
    'autoLoadSwiperJs' => false,
];

4. Use the plugin normally: The initSlider() helper will use your bundled Swiper installation automatically.

Option 2: Using CDN (Default)

The plugin auto-loads Swiper from CDN when enabled in settings:

CSS: https://cdn.jsdelivr.net/npm/swiper@11/swiper-bundle.min.css
JS: https://cdn.jsdelivr.net/npm/swiper@11/swiper-bundle.min.js

This is the easiest option but may not be ideal for production due to:

Additional HTTP requests
No control over caching
Dependency on external CDN availability

Option 3: Custom CDN or Version

You can use a different CDN or Swiper version by:

Disabling auto-loading in settings
Loading Swiper manually in your template:

{# In your layout template #}
<link rel="stylesheet" href="https://unpkg.com/swiper@10/swiper-bundle.min.css">
<script src="https://unpkg.com/swiper@10/swiper-bundle.min.js"></script>

    // Plugin settings
    'pluginName' => 'Slideshow',
    'autoLoadSwiperCss' => true,

Per-Entry - Using the Slideshow Config field
At Runtime - Via initSlider() overrides parameter

See Swiper API Documentation for all available options.

Examples

For comprehensive examples covering all features, see docs/examples.md.

Includes examples for:

Basic slideshow setup
Custom styling with CSS variables
Runtime config overrides and debug mode
Grid mode and different effects (fade, cube, coverflow, cards)
Responsive visibility controls
Autoplay configurations
Responsive breakpoints
Multiple sliders on one page
Custom Swiper installation (npm/yarn/pnpm)
Programmatic control and accessing Swiper instances
Advanced techniques like thumbnail navigation

Logging

Slideshow Manager uses the LindemannRock Logging Library for centralized logging.

Log Levels

Error: Critical errors only (default)
Warning: Errors and warnings
Info: General information
Debug: Detailed debugging (includes performance metrics, requires devMode)

Configuration

// config/slideshow-manager.php
return [
    'logLevel' => 'error', // error, warning, info, or debug
];

Note: Debug level requires Craft's devMode to be enabled. If set to debug with devMode disabled, it automatically falls back to info level.

Log Files

Location: storage/logs/slideshow-manager-YYYY-MM-DD.log
Retention: 30 days (automatic cleanup via Logging Library)
Format: Structured JSON logs with context data
Web Interface: View and filter logs in CP at Slideshow Manager → Logs

Log Management

Access logs through the Control Panel:

Navigate to Slideshow Manager → Logs
Filter by date, level, or search terms
Download log files for external analysis
View file sizes and entry counts
Auto-cleanup after 30 days (configurable via Logging Library)

Requires: lindemannrock/logginglibrary plugin (installed automatically as dependency)

See docs/LOGGING.md for detailed logging documentation.

Troubleshooting

Slideshow Not Initializing

Check browser console:

Look for JavaScript errors
Verify Swiper.js is loaded
Check data-swiper-config attribute exists

Verify auto-loading is enabled:

Go to Settings → Slideshow Manager → General
Ensure "Auto Load Swiper JS" is enabled

Clear caches:

./craft clear-caches/all

Navigation/Pagination Not Showing

Check config:

Verify navigation or paginationEnabled is true in your config
Check visibility settings aren't hiding elements

Check element classes:

Navigation: .swiper-button-prev-{{ sliderId }} and .swiper-button-next-{{ sliderId }}
Pagination: .swiper-pagination-{{ sliderId }}

CSS Variables Not Working

Verify auto-loading:

"Auto Load Swiper CSS" must be enabled in settings

Check config:

CSS vars must be configured in settings or config file
Use buildCssVars() in template

Browser support:

CSS custom properties require modern browsers
IE11 not supported

Field Not Saving

Check permissions:

Verify user has permission to edit entries

Clear caches:

Clear Craft caches and reload the entry
Check browser console for errors

Verify Live Preview:

Field works differently in Live Preview mode
Save the entry to persist changes
