A custom post type for choosing images and content which outputs a <a href="http://getbootstrap.com/javascript/#carousel" rel="nofollow ugc">carousel</a> from <a href="http://www.getbootstrap.com" rel="nofollow ugc">Twitter Bootstrap</a> using the shortcode <code>[image-carousel]</code>.
The plugin assumes that you’re already using Bootstrap, so you need to load the Bootstrap javascript and CSS separately.

CPT Bootstrap Carousel

A custom post type for choosing images and content which outputs Bootstrap Image Carousel (slider) from the [image-carousel] shortcode.

Andrés Villarreal

Agnosia Bootstrap Carousel hooks the <code>[gallery]</code> shortcode with attribute <code>type="carousel"</code> in order to show a <a href="http://getbootstrap.com/javascript/#carousel" rel="nofollow ugc">Bootstrap Carousel</a> based on the selected images and their titles and descriptions.
This plugin assumes either your theme includes the necessary Bootstrap javascript and CSS files to display the carousel properly, or that you have included those files on your own. It will not include the files for you, so if they are not present, the carousel will not work and you will only obtain its bare HTML.
<h4>Basic example:</h4>
<pre><code>[gallery type="carousel" ids="61,60,59"]
</code></pre>
<h4>Required attributes:</h4>
<ul>
<li><code>type</code>: it needs to be <code>type="carousel"</code>.</li>
<li><code>ids</code>: you must provide a list of <code>ids</code> corresponding to attachments, like <code>ids="1,2,3"</code>.</li>
</ul>
Otherwise, the default <code>[gallery]</code> shortcode function will be processed instead of this plugin’s one.
<h4>Optional attributes:</h4>
<ul>
<li><code>name</code>: any name. String will be sanitize to be used as an HTML ID. Recommended when you want to have more than one carousel in the same page. Default: agnosia-bootstrap-carousel. Example: <code>[gallery type="carousel" ids="61,60,59" name="myCarousel"]</code></li>
<li><code>indicators</code>: indicators position. Accepted values: before-inner, after-inner, after-control, false (hides indicators). Default: before-inner. Example: <code>[gallery type="carousel" ids="61,60,59" indicators="after-inner"]</code></li>
<li><code>width</code>: carousel container width, in <code>px</code> or <code>%</code>. Default: not set. Example: <code>[gallery type="carousel" ids="61,60,59" width="800px"]</code></li>
<li><code>height</code>: carousel item height, in <code>px</code> or <code>%</code>. Default: not set. Example: <code>[gallery type="carousel" ids="61,60,59" height="400px"]</code></li>
<li><code>titletag</code>: define HTML tag for image title. Default: h4. Example: <code>[gallery type="carousel" ids="61,60,59" titletag="h2"]</code></li>
<li><code>wpautop</code>: auto-format text. Default: true. Example: <code>[gallery type="carousel" ids="61,60,59" wpautop="false"]</code></li>
<li><code>title</code>: show or hide image title. Set false to hide. Default: true. Example: <code>[gallery type="carousel" ids="61,60,59" title="false"]</code></li>
<li><code>text</code>: show or hide image text. Set false to hide. Default: true. Example: <code>[gallery type="carousel" ids="61,60,59" text="false"]</code></li>
<li><code>containerclass</code>: extra class for carousel container. Default: not set. Example: <code>[gallery type="carousel" ids="61,60,59" containerclass="container"]</code></li>
<li><code>itemclass</code>: extra class for carousel item. Default: not set. Example: <code>[gallery type="carousel" ids="61,60,59" itemclass="container"]</code></li>
<li><code>captionclass</code>: extra class for item caption. Default: not set. Example: <code>[gallery type="carousel" ids="61,60,59" captionclass="container"]</code></li>
<li><code>control</code>: control arrows display. Accepted values: true (to show), false (to hide). Default: true. Example: <code>[gallery type="carousel" ids="61,60,59" control="false"]</code></li>
<li><code>interval</code>: the amount of time to delay between automatically cycling an item. If false, carousel will not automatically cycle. Default: 5000. Example: <code>[gallery type="carousel" ids="61,60,59" interval="2000"]</code></li>
<li><code>pause</code>: pauses the cycling of the carousel on mouseenter and resumes the cycling of the carousel on mouseleave. Default: “hover”. Example: <code>[gallery type="carousel" ids="61,60,59" interval="hover"]</code></li>
<li><code>size</code>: size for image attachment. Accepted values: thumbnail, medium, large, full. Default: full. See <a href="https://codex.wordpress.org/Function_Reference/wp_get_attachment_image_src" rel="nofollow ugc">wp_get_attachment_image_src()</a> for further reference. Example: <code>[gallery type="carousel" ids="61,60,59" size="full"]</code></li>
</ul>
<h4>Native supported attributes:</h4>
<ul>
<li><code>orderby</code>: Alternative order for your images. Example: <code>[gallery type="carousel" ids="61,60,59" orderby="rand"]</code></li>
