Slick Slider Default, Size and Image Link

Hi Philipp

I was able to partially fix the above by making use of the Function my_gallery_default_type_set_link (regarding the Link to). For the Default Size I have found a solution on stackoverflow .

So the only thing that I was not able to fix is that Slick Slicker is tick marked by default.

Hi @ivobirrer,
I’m really sorry for the delay; have been very busy in the past weeks.

I’m glad you were able to solve some of the issues on your own. For the sake of completeness I’d like to post “my” suggestion how to solve this.

Use the filter shortcode_atts_gallery (see the FAQ’s, question “Is it possible to change the gallery attributes using PHP?”):

/**
 * 1. Link images to media file.
 * 2. Set the image size to <code>large</code>.
 * 3. Always use Slick Slider.
 */
add_filter( 'shortcode_atts_gallery', function( $result, $defaults, $atts ) {
	$result['link'] = 'file'; // 1.
	$result['size'] = 'large'; // 2.
	$result['slick_active'] = true; // 3.
	return $result;
}, 10, 3 );

Note: Substitute image size large with your custom image size.

The main difference to the media_view_settings hook is that shortcode_atts_gallery is only executed for galleries and not for all media files.

Important note: The current version of Slick Slider (0.5.1) does not respect slick_active set with the shortcode_atts_gallery filter. I made a change on the development version to add support for this. You need to manually install it to make it work.

The next version will probably have a setting on the Media Settings page to always enable Slick Slider.

I hope this is useful for you.

Hi Philipp

No issue. Glad that you found time to answer my Questions. I have tried the above solution but Slick-Slider stops running as soon as I add the above filter. It simply shows the native gallery again.

Ah, my bad.

I was testing the code against the unpublished in-development version of this plugin. $result['slick_active'] = true; (boolean) will only work from the next version on. For now, you’ll have to write $result['slick_active'] = 'true'; (string).

Sorry for this!

Note that on the gallery modal the checkbox “Use Slick Slider” will have no effect and will stay unchecked. Don’t get confused by this.

Runs like a charm. Many thanks for your outstanding support!

Tried to switch-off Slick-Slider for one of my Galleries by adding slick_active=”false” to the Shortcode. Same I tried for the “Link to” because I use Slick-Slider also in the Widgets and there images should not be linked to anywhere. But now it seems that any tweaking to the Shortcode is ignored, right?

BTW: Another Donation is on its way to you.

That’s a legitimate objection.
Let’s check if the attributes are set in the shortcode (meaning they differ from the WordPress defaults, see below) and if so, don’t overwrite them:

/**
 * 1. Link images to media file.
 * 2. Set the image size to <code>large</code>.
 * 3. Always use Slick Slider.
 */
add_filter( 'shortcode_atts_gallery', function( $result, $defaults, $atts ) {
	if ( ! isset( $result['link'] ) ) {
		$result['link'] = 'file'; // 1.
	}
	if ( ! isset( $result['size'] ) ) {
		$result['size'] = 'large'; // 2.
	}
	if ( ! isset( $result['slick_active'] ) ) {
		$result['slick_active'] = 'true'; // 3.
	}
	return $result;
}, 10, 3 );

The default value for link is “Attachment Page”, for size is thumbnail. See Gallery Shortcode for details.

I hope we get closer to a useful solution.

Thanks for your donation!

Philipp, great job!

Exactly what I was looking for. Many thanks for your very appreciated support and this great plugin.

Would be great if you could implement this into the Settings Page. This came up because my fellow colleagues often forget to maintain the right settings (e.g. Slick Slider = on, Link to = File and preferred Image-Size).

I’m glad it’s working for you. Set to resolved.
