Example

Assume that {{cart.items}} would return 10 items. You could use this helper to limit that behavior to only the first four items, by specifying:

{{#each (limit cart.items 4)}}
    <li class="previewCartItem">
        <div class="previewCartItem-image">
            {{#if type '==' 'GiftCertificate'}}
                <img src="{{cdn ../../theme_settings.default_image_gift_certificate}}" alt="GiftCertificate" title="GiftCertificate">
            {{else}}
                {{> components/common/responsive-img
                    image=image
                    fallback_size=../../theme_settings.productthumb_size
                    lazyload=../../theme_settings.lazyload_mode
                    default_image=../../theme_settings.default_image_product
                }}
            {{/if}}
  ...

See it in Cornerstone.

For one specified search key(s), it retrieves corresponding values from some or all elements in a specified collection.

The pluck helper returns the retrieved values in a comma-separated string. This helper’s general form is:

{{pluck ([limit] <collection> [<limit-value>]) '<search-key>'}}

Parameters

limit, limit-value: Optional parameters to limit the number of results returned.
collection: The collection to search.
search-key: The string to search for.

Example

If each category in categories contains an image object, use dot notation to access the image’s children:

categories: [
  { "id": 1, "name": "Bakeware", "image": { "data": "http://...", "alt": "Bakeware image"} },
  { "id": 2, "name": "Cookware", "image": { "data": "http://...", "alt": "Cookware image"} },
  { "id": 3, "name": "Cutlery", "image": { "data": "http://...", "alt": "Cutlery image"} }
]

Handlebars statement:

{{pluck (limit categories 2) 'image.data'}}
<!-- Returns a comma-separated list of image URLs -->

See it in Cornerstone.

A URL transformer for content delivery networks.

Example

When you reference static assets that you have locally staged outside your <theme-name> directory and uploaded using WebDAV, place the webdav: prefix before each corresponding assetPath parameter. For example, a link like:

<img src="{{cdn 'webdav:img/image.jpg'}}">

will be transformed to a result like:

<img src="https://cdn.bcapp/3dsf74g/content/img/image.jpg">

The presumed WebDAV root directory is /content/. (So, in this example, the image.jpg file has been uploaded to the WebDAV /content/ directory.) The presumed local directory is assets/, so you can omit that path when referencing its contained files or subdirectories.

See it in Cornerstone.

CDN custom endpoints

You can define custom CDN endpoints to use with the cdn helper. This facilitates including large, high-resolution image assets in themes, without exceeding BigCommerce’s 50 MB limit when bundling the theme for upload to BigCommerce.

You could use a local version of the image in development, and a version on a CDN (e.g. Imgix) in production. To do so, define custom CDN endpoints in your theme’s config.json file, as highlighted in the example below:

{
  "name": "Cornerstone",
  "version": "1.3.5",
  "settings": {
    "homepage_new_products_count": 12,
    "homepage_featured_products_count": 8,
    "cdn": {
      "customcdn": "https://bigcommerce.customcdn.net"
          }
     }
}

After defining an endpoint, you can use the short name in the same way as you would use a webdav: abbreviation:

<img src="{{cdn 'customcdn:img/image.jpg'}}" />

In local development, that helper would return:

<img src="/assets/cdn/customcdn/img/image.jpg"/>

Whereas in production, it would return:

<img src="https://bigcommerce.customcdn.net/img/image.jpg" />

As highlighted above, the helper is configured to rewrite local URLs to a assets/cdn/ subfolder. The stencil bundle command will exclude this local assets/cdn/ subfolder from the bundle that it creates. This filtering circumvents the 50 MB size limit on the resulting .zip file.

Format number length, thousands delimiter, and decimal delimiter.

See it in Cornerstone.

The getImageSrcset helper is a replacement for getImage which allows you to generate either a single image URL (for an <img> src) or a list of image sizes for srcset. Srcset allows you to specify a list of sizes from which the browser may choose, based on the expected size of the image on the page, the device’s pixel density, and other factors.

Similar to getImage, it accepts an stencilImage parameter, and optionally, a defaultImage to use as a fallback.

Parammeters

stencilImage: a StencilImage
defaultImage : a fallback image URL to use if the StencilImage is undefined.
Image sizes specified as named parameters on the helper

You can then specify what sizes you want as named arguments on the helper.

Examples

Default sizes

By specifying use_default_sizes=true on the helper, a srcset string will be constructed with a set of sizes chosen by BigCommerce to be optimal for most uses.

{{getImageSrcset image use_default_sizes=true}}
{{getImageSrcset image "https://place-hold.it/500x300" use_default_sizes=true}}

Default sizes:

'80w': '80w',
'160w': '160w',
'320w': '320w',
'640w': '640w',
'960w': '960w',
'1280w': '1280w',
'1920w': '1920w',
'2560w': '2560w',

Single 1x size

{{getImageSrcset image 1x=theme_settings.zoom_size}}
{{getImageSrcset image 1x="1280x800"}}
{{getImageSrcset image 1x="1280w"}}

By specifying a single size as the ‘1x’, size, you can choose to get an image at any size of your choosing. You can reference a value from the theme_settings object (similar to getImage), or you can specify your own size inline. Note that getImageSrcset does not require theme_settings keys to be wrapped in quotes; they should be referenced directly.

Pixel density

{{getImageSrcset image 1x="1280w" 2x="2560w"}}
{{getImageSrcset image 1x="800w" 1.5x="1200w" 2x="1600w"}}
{{getImageSrcset image 1x="640x640" 2x="1280x1280"}}

By specifying several sizes using the pixel density descriptor, you can generate a srcset of different image resolutions for different pixel density screens as described here. For example, you can specify a 2x image for Retina screens, and a 1x image for normal screens.

As above, you can reference theme_settings keys or specify your own size inline.

Inherent width

<img src="{{getImage image 'default'}}" srcset="{{getImageSrcset image 100w='100w' 200w='200w' 300w='300w'}}" />

<!-- =>
<img src="https://cdn11.bigcommerce.com/s-abc123/images/stencil/640x640/products/86/286/ablebrewingsystem4_1024x1024__07155.1456436672.jpg?c=2" srcset="https://cdn11.bigcommerce.com/s-abc123/images/stencil/100w/products/86/286/ablebrewingsystem4_1024x1024__07155.1456436672.jpg?c=2 100w, https://cdn11.bigcommerce.com/s-abc123/images/stencil/200w/products/86/286/ablebrewingsystem4_1024x1024__07155.1456436672.jpg?c=2 200w,https://cdn11.bigcommerce.com/s-abc123/images/stencil/300w/products/86/286/ablebrewingsystem4_1024x1024__07155.1456436672.jpg?c=2 300w" />
-->

<img src="{{getImageSrcSet image 1x='1000x1000'}}" srcset="{{getImageSrcset image 1x='1000x1000' 2x='2000x2000'}}" />

<!-- =>
<img src="https://cdn11.bigcommerce.com/s-abc123/images/stencil/640x640/products/86/286/ablebrewingsystem4_1024x1024__07155.1456436672.jpg?c=2" srcset="https://cdn11.bigcommerce.com/s-abc123/images/stencil/100w/products/86/286/ablebrewingsystem4_1024x1024__07155.1456436672.jpg?c=2 100w, https://cdn11.bigcommerce.com/s-abc123/images/stencil/200w/products/86/286/ablebrewingsystem4_1024x1024__07155.1456436672.jpg?c=2 200w,https://cdn11.bigcommerce.com/s-abc123/images/stencil/300w/products/86/286/ablebrewingsystem4_1024x1024__07155.1456436672.jpg?c=2 300w" />
-->

By specifying several sizes using the inherent width descriptor, you can generate a srcset of different image resolutions based on width, which can in turn be selected by the browser based on the expected size of the image when the page is painted. It is recommended to use this together with a sizes attribute on the <img> as described here. In Cornerstone, this is handled automatically via JavaScript.

As above, you can reference theme_settings keys or specify your own size inline.

See it in Cornerstone.

Renders block if one or more parameters is true. Parameters can be of different types (strings, numbers, arrays, or collections).

Example

The any helper is invoked as shown here:

{{#any items selected=true}}
  <!-- block to display if any items have selected=true -->
{{/any}}

A usage example is templates/components/category/shop-by-price.html, a category page in Stencil’s Cornerstone base theme that does not have faceted search turned on. Shoppers will see “Shop by price” filters instead of product filters.

In this component, the {{#any... helper is used to determine whether a shopper has selected one of the filters, and whether a “reset” button needs to be displayed:

{{#any shop_by_price selected=true}}
    <li class="navList-item">
        <a href="{{category_url}}" class="navList-action">
            {{lang 'category.reset'}}
        </a>
    </li>
{{/any}}

See it in Cornerstone.

Renders block if all parameters are true. Parameters can be of different types (strings, numbers, arrays, or collections).

Example

{{#all items theme_settings.optionA theme_settings.optionB}}
  ... /* block to display, if all items evaluate to true */
{{/all}}

{{#all product.custom_fields theme_settings.show_custom_fields_tabs}}
    <li class="tab">
        <a class="tab-title" href="#tab-{{dashcase (lowercase (sanitize theme_settings.pdp-custom-fields-tab-label))}}">{{sanitize theme_settings.pdp-custom-fields-tab-label}}</a>
    </li>
{{/all}}

See it in Cornerstone.

Render block if comparison of first and third parameter returns true.

Parameters

a {}
operator {}: The operator to use. Operators must be enclosed in quotes: “>”, “=”, “<=”, and so on.
- ==
- ===
- !=
- !===
- <
- >
- <=
- >=
- typeof
b {}
options {Object}: options object
returns {String}: Block, or if specified the inverse block is rendered if falsey.

See it in Cornerstone.

Renders the block if collection has the given value, using strict equality (===) for comparison, otherwise the inverse block is rendered (if specified). If a startIndex is specified and is negative, it is used as the offset from the end of the collection.

Params

collection {Array|Object|String}: The collection to iterate over.
value {any}: The value to check for.

Example

<!-- array = ['a', 'b', 'c'] -->
{{#contains array "d"}}
  This will not be rendered.
{{else}}
  This will be rendered.
{{/contains}}

See it in Cornerstone.

Repeats block for range from index a to element b.

Parameters

a: starting integer
b: ending integer

In particular, this helper is limited to 100 iterations, in order to protect against infinite loops.

The for helper has the following syntax, where parameters <from> and <to> are numbers, and <context> is an object:

Example

{{#for 1 12}}
    {{lang (concat 'common.short_months.' $index)}}
{{/for}}

See it in Cornerstone.

Renders if block when if-statement evaluates to true; otherwise renders else block.

Example

{{#if page_type '===' 'account_order'}}
    <li class="navBar-item is-active">
        <a class="navBar-action" href="{{urls.account.orders.all}}">{{lang 'account.nav.orders'}}</a>
    </li>
{{else}}
    <li class="navBar-item is-active">{{lang 'account.nav.orders'}}</li>
{{/if}}

See it in Cornerstone.

Renders block if on more param evaluates to true.

Parameters

The or operator’s parameters are one or more strings, numbers, arrays, or collections. Parameters can be of mixed types.

Example

{{#or 1 0 0 0 0 0 0}}
<!-- 1 evaluates to true, so block rendered-->
{{/or}}

{{#or options configurable_fields}}
    <a href="#" data-item-edit="{{id}}">{{lang 'cart.checkout.change'}}</a>
{{/or}}

See it in Cornerstone.

Renders block if statement is false; does not support operators for comparison expressions.

Example

{{#each category_results}}
<li class="category-suggestion">
    {{#each this}}
        <a href="{{url}}">{{name}}</a>
        {{#unless @last}} > {{/unless}}
