JJ NextGen JQuery Carousel

Description

The ‘JJ NextGen JQuery Carousel’ allows you to create a ‘JCarousel’ (https://sorgalla.com/projects/jcarousel/) as a widget or as a shortcode.
This plugin uses the ‘NextGen Gallery’ plugin for its images.

Requirements:

• NextGen Gallery Plugin (https://www.ads-software.com/extend/plugins/nextgen-gallery/)

NextGen Gallery Integration:

• This plugin uses the original width and height of the image uploaded so make sure the images are the correct dimensions when uploaded.
• If a width and height are defined under the configuration all images will be resized to those dimensions (Highly recommended).
• Alt & Title Text Field: Provide a full url here and the image will link to this. Only works if alt field starts with either of these; /, http, or ftp.
• Description Field: Will be used as image alt text. If alt text is present but not a valid url alt text will be used instead for image alt text.

You can specify the following parameters:

NOTE: sc means shortcode:

• Title: Title. Leave blank for no title. (sc: title=”My Carousel”)
• Gallery: Leave blank to use all galleries or choose a gallery to use. (sc: gallery=”galleryid”)
• Order: Order to display results in. You can choose; Random, Latest First, Oldest First, or NextGen Sortorder. Random will still work when a page is cached. (sc: order=”random”|”asc”|”desc”|”sortorder”)
• Shuffle: If order is random and this is true will shuffle images with javascript. Useful if your are caching your pages. (sc: shuffle=”true”|”false”)
• Max pictures: The maximum amount of pictures to use. (sc: max_pictures=”6″)
• HTML id: HTML id to use. Defaults to ‘jcarousel’. Needs to be different for multiple instances on same page. (sc: html_id=”jcarousel”)
• Skin class: Class of skinning to use. Defaults to use the tango skin. (sc: skin_class=”jcarousel-skin-tango”)
• Image width: Width of image. Defaults to 75. (sc: width=”200″)
• Image height: Height of image. Defaults to 75. (sc: height=”150″)
• Image gap: Gap between images. (sc: gap=”5″)

JCarousel settings:

Please check the JCarousel home page for more details (https://sorgalla.com/projects/jcarousel/#Configuration).

• vertical: Specifies wether the carousel appears in horizontal or vertical orientation. Changes the carousel from a left/right style to a up/down style carousel. (sc: vertical=”setting”)
• rtl: Specifies whether the carousel appears in RTL (Right-To-Left) mode. (sc: rtl=”setting”)
• start: The index of the item to start with. (sc: start=”setting”)
• offset: The index of the first available item at initialisation. (sc: offset=”setting”)
• size: Size of existing elements if size is not passed explicitly uses the number of total items. (sc: size=”setting”)
• scroll: The number of items to scroll by. (sc: scroll=”setting”)
• visible: If passed, the width/height of the items will be calculated and set depending on the width/height of the clipping, so that exactly that number of items will be visible. (sc: visible=”setting”)
• animation: The speed of the scroll animation as string in jQuery terms (“slow” or “fast”) or milliseconds as integer (See jQuery Documentation). If set to 0, animation is turned off. (sc: animation=”setting”)
• easing: The name of the easing effect that you want to use (See jQuery Documentation). (sc: easing=”setting”)
• auto: Specifies how many seconds to periodically autoscroll the content. If set to 0 (default) then autoscrolling is turned off. (sc: auto=”setting”)

FAQ

Question:

• How do you make a new skin?

Answer:

• Make a copy of the skins/tango folder located in the plugin folder.
• Rename folder to something else.
• Copy folder to a location where you can create a link to it in the head of your html page. Don’t put in plugins folder or your changes could be lost in updates.
• In skin.css file replace all ‘.jcarousel-skin-tango’ selectors with your own eg, ‘jcarousel-skin-custom’.
• Make your modifications to skin.css.
• Import your new skin.css file in to your html page.
• Use the ‘Skin class’ field in the widget or the shortcode skin_class to assign your new skin class eg, ‘jcarousel-skin-custom’.

Question:

• How do you make carousel scroll in the other direction?

Answer:

• Make scroll parameter a negative number eg -1 or -2 etc. Note: make sure auto is set to number of seconds for auto scrolling.

Question:

• How can I use plugin inside normal PHP code?

Answer:

• echo do_shortcode(‘[jj-ngg-jquery-carousel html_id=”about-jcarousel” gallery=”2″ width=”150″ height=”100″ visible=”2″ scroll=”1″ auto=”3″]’);

Question:

• Doesn’t work after upgrade? or Doesn’t work with this theme?

Answer:

• Please check that you don’t have two versions of jQuery loading, this is the problem most of the time. Sometimes a theme puts in
  tags at the end of newlines aswell.
