Slick Slider

FAQ

I don’t want all galleries to become sliders! Is this possible?

Absolutely! On each gallery Media Modal there’s a checkbox called “Use Slick Slider”. If you leave this box unchecked your gallery will be a simple … gallery.

Is it possible to place the slider somewhere else, say in a widget?

Since Slick Slider uses the default gallery shortcode, you can simply paste it wherever you want it to appear.
Note that you may need to enable support for shortcodes in widgets. Additionally if you want to edit the slider options you’ll have to change it using the shortcode attributes directly.

Is it possible to specify custom links for the gallery images?

Use the plugin WP Gallery Custom Links.

Note: Only support for custom URLs and link targets (including the filter wpgcl_filter_raw_gallery_link_url). No support for additional custom fields or shortcode attributes.

Is it possible to open linked images in a lightbox?

Use the plugin WP Featherlight.

Note: The gallery’s setting “Link To” has to be set to “Media File”.

Is it possible to add captions?

Use the option “Show caption”.

Note: The captions aren’t styled. You need to apply some CSS on them (use the class .slide__caption).

Is it possible to use slick’s JS and CSS independently?

Paste the following lines in your functions.php:

add_action( 'wp_enqueue_scripts', function() {
    wp_enqueue_script( 'slick-slider-core' );
    wp_enqueue_style( 'slick-slider-core-theme' );
}, 11 );

Is it possible to prevent slick’s JS and CSS to get loaded?

Paste the following lines in your functions.php:

add_action( 'wp_enqueue_scripts', function() {
    wp_deregister_script( 'slick-slider-core' );
    wp_deregister_style( 'slick-slider-core' );
}, 11 );

Note: This will also remove the initiation script and helper CSS from the page (see below).

Is it possible to prevent the slider from getting automatically initiated?

Use add_filter( 'slick_slider_init_slider', '__return_false' );.

Is it possible to prevent the plugin from adding additional helper CSS on my page?

These three line of CSS are sometimes required if the page has a white background. Otherwise the slider arrows won’t be visible.
You can turn it off by using add_filter( 'slick_slider_load_helper_css', '__return_false' );.

Is it possible to change the gallery attributes using PHP?

Use the WordPress core filter shortcode_atts_gallery.

Is it possible to adjust the caption’s markup?

Use the filter slick_slider_caption_html. Parameters: caption HTML, attachment ID, post ID, slider instance.

Is it possible to adjust the markup for each slide?

Use the filter slick_slider_slide_html. Parameters: slide HTML, attachment ID, post ID, slider instance.

Is it possible to adjust the markup for the entire slider?

Use the filter slick_slider_html. Parameters: slider HTML, post ID, slider instance.

Is it possible to enqueue scripts and styles unminified?

Use the constant SCRIPT_DEBUG.

I want to buy you a beer!

Thats great, thanks! First of all, you should say thank you to Ken Wheeler who developed the actual slick slider.
If you want, you can buy me a beer too.
