1. Catalog expressions

Most of these expressions can be used inside a catalog page. templates, header or footer

  • {{Current Date}} - current timestamp on the server (UTC time)
    Use custom formatting, e.g. {{Current Date:MMMM dd, yyyy}}, where
    MM, MMM, MMMM - month (digits, short, full), d, dd, ddd, dddd (day, week), yy, yyyy - year

  • {{Section Name}} - defined in Table of Contents  setting

  • {{Page Number}} - a current catalog page number

Flags for a product price list  (or variant, categories, collection lists)

  • {{AltRow}} - even row flag

  • {{IsFirst}}, {{IsLast}} - first or last elements flag

  • {{IsPDF}} - displays in PDF

{{If IsPDF}}PDF{{Else}}Online{{/If}}

<div style="background-color:{{If AltRow}}#54acd2{{Else}}#ffffff{{/If}};">
...
</div>

Any text expression can use character limit. For example

  • {{Description:50}} or {{Name: 20}} that will produce text my description... if it exceeds the limit

Barcodes

  • Use {{BarcodeImage}} or {{BarcodeImageExt}} to display a barcode image, if the field name is different (e.g. MyField) use {{BarcodeImage:MyField}} or {{BarcodeImageExt:MyField}}

  • BarcodeImageExt - display image with a code text below

  • You can use barcode image with a code directly {{BarcodeImageExt:89567894}}

2. Products

Products have built-in fields (e.g. Name, Code, etc.) and custom fields defined by you on the category level (e.g. Price, Image, Retail Price, Shop Link, etc.).

Usage: These fields could be used in product text box or inside product iterator.
Example :
{{Name}} {{Description}}
{{Products}} {{Name}} - {{Price}} {{/Products}}

Product built-in  and standard fields:

  • Code

  • Name

  • Category

  • Rank – also used in showroom for ordering

  • Modified – date product last modified

  • VariantCount – number of product variants

  • Image

  • Description

  • Price

  • Category and collection fields - Category.Name, Collection.Description, etc. (see the following section)

Product prices: {{Price:#,###.00}}, {{Calc: Price * 1.13 - Discount}}
You can display price fields (with type Money or Number) with custom formatting and calculation based on other fields. Read more about displaying product prices.

Examples:
{{Price:#,###.00}} displays 1,200.50 for price field 1200.5
{{Sale Price:#}} displays number without fractions 10 for Sales Price field 10.99
{{MSRP: C #.###,00}} displays € 1,200,50 for MSRP field €1200.5, but 1,200,50 if no currency in the field.
{{Calc: 2 + 2}} displays 4
{{Calc: Price * 1.13: #.00}} displays 11.30 for Price field 10
{{Calc: Price * (100 - Discount) / 100: #,###}} displays 8 for fields Price = 10 and Discount = 15

Use parameters for shared values like currency rates or discounts

${{Calc: Price * USD Rate: #.00}}

Link: {{Link: Address Field or address : Field or custom text}} 

You can display a link to any web page based on your product fields. Read more about displaying a link to the external web page.

Examples
{{Link:Store Link:Name}}  will display a link with the address from Store Link field and and link text from product Name field.
{{Link:My Link}} displays a link with the address from My Link product field using the address a link text
{{Link:Site Link:Click here}} displays a link with address from Site Link product field with custom text 'Click here'.
{{Link:www.google.com:Google}} - displays a link to www.google.com with a text 'Google'

Product iterator: {{Products:condition operators}}content…{{/Products}}

Example:
{{Products: Category = Shoes : Price > 0 : Order By > Code }}
{{Name}} - {{Description}} - ${{Price}}
{{/Products}} 

You can use individual iterators {{Product1}} and {{Products2}} to create cross tables. The product iterator should have the prefix Product1. (or Product2.)

Example:

{{Products1: Product1.Category=Feature}}
{{Product1.Image:Fit:40:40}}{{Product1.Name}}
{{/Products1}}

3. Categories / Collection

Usage: Category and collection fields can be used inside category iterator or  product text

Category / Collection fields:

  • Name

  • FullName – includes parent name if exists

  • Description

  • Color

  • Parent –  parent collection  / category

  • ProductCount – number of products in this category

  • FullProductCount – number of products in this and child category

  • Thumbnail – category thumbnail image

Product text box

{{Category.Name}} same as {{Category}}
{{Collection.Description}}

Category iterator: {{Categories:condition operators}}content…{{/Categories}}

Examples:
{{Categories: ProductCount > 0}}
{{Thumbnail:Fit:50:50}}  {{Name}} ({{ProductCount}}) {{Description}}
{{/Categories}}

{{Categories: Parent = Clothing}}{{Name}}{{Products}}{{Name}} - ${{Price}}{{/Products}}{{/Categories}}

4. Variants

Variants have built-in fields and configured on category level options (e.g. Color, Size). You can reference options by name or index – Color or Option:1 (same as Option), Size or Option:2.
Use Option:1:Title for the name of the first option 

Usage: These fields could be used only inside the variant iterator.
Example : 

{{Variants}} {{SKU}} {{Option:1}} / {{Option:2}} - {{Price}} {{/Variants}}
{{Variants}} {{SKU}} {{Color}}/{{Size}} - {{Price}} {{/Variants}}
{{Variants}} {{SKU}} {{Option:1:Title}} : {{Option:1}} {{/Variants}}

{{/Variants}}

{{Variants:OrderBy > SKU}}
{{SKU}} - {{Option}}{{Separator:,}}
Barcode: {{Barcode}}
Quantity: {{Quantity}}

{{/Variants}}
  • You can iterate product and category options titles with {{OptionTitle}} .

{{Categories}}
{{Options}} {{OptionTitle}} {{/Options}}
{{/Categories}}

 It could be used in table headers html (switch to edit in code view)

<!--{{Categories: ProductCount > 0 }}-->
{{Name}}
<table>
<tr>
    <th>Name</th>
    <!--{{Options}}-->
    <th>{{OptionTitle}}</th>
    <!--{{/Options}}-->
</tr>
<!--{{Products}}-->
<tr>
    <td>{{Name}}</td>
    <!--{{Options}}-->
    <td>{{Variants}}{{OptionValue}}{{/Variants}}</td>
    <!--{{/Options}}-->
</tr>
<!--{{/Products}}-->
</table>
<!--{{/Categories}}-->

5. Images

Image fields (product, variants, category thumbnail) could have additional parameters – positioning, width, and height to align with rest of text.

Format: {{Image:Position:Width:Height}}

Position could be  Fit, Fill, Stretch,Center,Default

Example:
{{Image}} - automatically sized
{{Image:Fit:200:100}} - sized to fit into box 200 x 100 pixels 

6. Condition Operators

These are condition operators you can use in any iterator or {{If}}

Operators:

  • ~ contains as sub string: {{Products:Description ~ Sale}}

  • = – text is equal {{Products: Category = Shoes}}

  • <> – text is not equal {{Products: Category <> Shoes}}

  • <,<=,>,>= – compare numbers (or text in alphabetical order){{Products: Price > = 10 : Price <= 100}}{{Categories: ProductCount > 0}} 

  • ! in front of condition makes it negative {{Products: !Description~Sale}}

  • ^ field is included in comma delimited list: {{Products: Category ^ Shirts, Jeans}}

7. Sort, limit and unique operators

These expressions can be used in any iterator. You can also use them in paging scenario

  • OrderBy – sort by descending (>) or ascending order (<)
    {{Products: OrderBy > Price}} – price in descending order
    {{Products: OrderBy < Price}} – price in ascending order

  • LimitBy – take only limited number of items
    {{Products: LimitBy = 50 }} – first 50 products
    {{Products: LimitBy = 10 : OrderBy > Price}} – top 10 products by price

  • SkipBy – skip first number of items
    {{Products: SkipBy = 10 }} – skip first 10 products
    {{Products: Category = Shoes : SkipBy = 20: LimitBy = 10 : OrderBy > Code }} – skip first 20 products  and show next 10 products in category Shoes ordered by Code

  • Unique - display only unique values from the list Unique = [Field Name]

    {{Products: VariantCount > 0}} 
    {{Name}}
    {{Variants: Unique=Color}}{{Color}}{{/Variants}}
    {{/Products}}
  • show products page links - the iterator displays only if the category changes

    <table>
    <!--{{Products : Unique = Category }}-->
    <tr>
    <td>{{Category}}</td>
    <td>{{Product Page Link}}</td>
    </tr>
    <!--{{/Products}}-->
    </table>

8. Conditional text

Use {{If condition}}…{{/If}} to show text if condition is true. You can use extended version {{If...}}...yes...{{Else}}...no...{{/If}}

Examples:
{{If Price > 100}} High price {{Else}} Low price {{/If}}
{{If Tag~sale}} Sale: {{Sale Price}} {{/If}} 

Check empty fields:
{{If Price}} Price: {{Price}} {{/If}}

For negative condition put ! before expression
{{If !Price}} No price {{/If}}
{{If !Description}}{{Category.Description}}{{/If}}
​ 

Or combine both outcomes with {{Else}}:
{{If Price > 0 }} Price: {{Price}} {{Else}} No price {{/If}}}
{{If Description}}{{Description}}{{Else}}{{Category.Description}}{{/If}}

You can use it inside any iterator

{{Products}} {{Name}} - {{If Price=0}} N/A {{/If}} {{If Price>0}} ${{Price}} {{/If}} {{/Products}}

Check variant properties of the product 

{{If Variants:Color=Red}}Red exists{{/If}}
