Creating dynamic sliders with Soliloquy for free

I wanted to create a simple dynamic slider using Advanced Custom Fields, but Soliloquy does not have this option out of the box. After poking around the source of Soliloquy I found the filter soliloquy_custom_slider_data which lets us add our own slider data. Here is the required code to dynamically generate a slider. (This code is not ACF-specific, you can use any data source.)

Your slider will be available using the shortcode:

[soliloquy type="frontpage"]

The code to generate this dynamic slider:

add_filter('soliloquy_custom_slider_data', function($data, $atts, $post) {

    //Bail early if not our slider type
    if(isset($atts['type']) && $atts['type'] !== 'frontpage') {
        return $data;
    }

    $data_dynamic = [
        'id' => 0,
        'slider' => [
            //This is where you enter all your dynamic slides!
            //72 and 73 below are the IDs of the image attachments used in the slider. 
            72 => [
                'status' => 'active',
                'id' => 72,
                'attachment_id' => 72,
                'title' => 'Image title',
                'link' => 'http://example.com',
                'alt' => 'Alt text',
                'caption' => 'Caption',
                'type' => 'image',
                'linktab' => 0
            ],
            73 => [
                'status' => 'active',
                'id' => 73,
                'attachment_id' => 73,
                'title' => 'Image title',
                'link' => 'http://example.com',
                'alt' => 'Alt text',
                'caption' => 'Caption',
                'type' => 'image',
                'linktab' => 0
            ]
        ],
        'config' => [
            //This is the general slider config
            'type' => 'default',
            'slider_theme' => 'base',
            'slider_width' => 1080,
            'slider_height' => 400,
            'transition' => 'fade',
            'duration' => 5000,
            'speed' => 400,
            'gutter' => 20,
            'slider' => 1,
            'aria_live' => 'polite',
            'classes' => [
                'frontpage-slider'
            ],
            'title' => '',
            'slug' => '',
            'rtl' => 0
        ]
    ];

    return $data_dynamic;
}, 11, 3);

I am using Soliloquy Lite, although I’m sure this works with the paid options as well. You can also easily create multiple dynamic sliders, each pulling data from different sources.
