The display pattern and filters are written in Liquid Syntax, which is the Shopify templating language. It has objects (the field values), filters (manipulations like uppercase) and tags (if/else operations). Please make yourself familiar when you plan to update the display pattern with specific patterns.

{% if %}
 {{data.layerid.fieldid | filter}}
{% endif %}

In general, Liquid has three different types you can work with:

• Objects: The value of the field you want to access. Always written in two pairs of curly braces. Access a field from a layer, and be aware that objects in Picturepark always start with data: data.layer.text
• Filters: Change the output, e.g., append text, uppercase. Always added with a pipe to the objects inside the curly braces. Append Picturepark to the value: | append " Picturepark". You can add multiple filters to one value to translate, truncate, and append in one statement: {{data.layer.text | translate | truncate | append }}
• Tags: For logic operations, e.g., if the field has a value. Always written in a pair of curly braces with a percentage symbol. Check if field exists: {% if data.layer.field %} {% endif %}

Find additional information and examples listed here: http://help.current-rms.com/en/articles/1040768-an-introduction-to-liquid-syntax

{% if data.layer.field %}
 {{data.layer.field | append " Picturepark"}}
{% endif %} 

The Picturepark display pattern uses Liquid objects for the field values. You can access all information directly. 

1. Data.Schema.Field ( Data.Schema.Field ) will result in "Value1 (Value2)"
2. Data.Schema.Field will result in “Value”

As tagboxes store multiple values (tags) you must use a liquid tag, the for loop: 
{% for item in Data.SchemaIAm.FieldAffectedFromSchemaIAm %} {{ item.FieldnameFromReferencedSchema.Language}} {% endfor%}

Display Pattern Liquid Filters

Liquid Filters are supported, but the C# naming convention must be respected. Find here an extensive list of possible filters, some of which may not work in Picturepark. 

Look here for more filters: https://github.com/Shopify/liquid/wiki/Liquid-for-Designers#standard-filters

{{data.schema.Textfield | truncate: 5, '' }}

• truncates down to 5 characters

{{data.schema.Textfield | truncate: 5, '...' }}

• truncates down to 5 characters and append three dots

{{data.schema.Textfield | upcase }}

• converts the values to uppercase

{{data.schema.Textfield | append: ' VIT' }}

• appends VIT to the values

{{data.fileMetadata.fileName | replace: data.imageMetadata.fileExtension , "" }}

• replaces the file extionsion in the original file name with nothing aka removes the file extension

{{data.schema.Textfield | capitalize }}

• capitalizes every word

{{data.schema.Textfield | downcase }}

• converts the values to lowercase

{{data.schema.Textfield | prepend: 'Picturepark' }}

• prepends Picturepark to the value in the field

If you find a specific filter you want to use that is not working, please contact support@picturepark.com.

Additional Picturepark Liquid Filters

{{data.fieldpath2textfield | translate }}

• Displays the correct translated value of the field, if available, even without display pattern translations.

{{data.fieldpath2tagboxfield | tagbox_name }}

• Use the name pattern of the linked lists for display

{{data.fieldpath2tagboxfield | tagbox_list }}

• Use the list pattern of the linked lists for display

{{data.fieldpath2datefield | local_date}}

• Displays the date value in your computer's regional setting time zone. 

Date Format Syntax

You can format the date to different formats, the syntax is like strf.

• %m > month as 01..12
• %b > month as Jan…Dec
• %Y > year with century as 2021
• %y > year without century as 21

{{data.xmpMetadata.xmp.createDate | date: "%Y-%m"}}
Output: 2021-06
{{data.xmpMetadata.xmp.createDate | date: "%Y"}}
Output: 2021
{{data.xmpMetadata.xmp.createDate | date: "%m, %Y"}}
Output: 06, 2021
