ਫਰਮਾ:Item
 | ਇਹ ਫਰਮਾ ਹੇਠ ਲਿਖੇ ਲੂਆ ਨੂੰ ਵਰਤਦਾ ਹੈ: |
This template packs structured data into a compact item, which can be passed as a parameter to another template. This allows to pass multiple structured items to that template, which can iterate over the items and extract data from them.
Usage[ਸੋਧੋ]
The structured data item contains all parameters (both numbered ones and named ones) passed to the {{Item}} template. For example, {{Item|Alice|Bob|best=Eve}} creates an item with components 1=Alice2=Bobbest=Eve
Multiple items will be passed to an example recipient template {{User:Petr Matas/sandbox/Pets}} like this:
| Markup | Renders as |
|---|---|
{{User:Petr Matas/sandbox/Pets|owner=Bob
| {{Item|name=Tom|animal=cat|legs=4}}
| {{Item|name=Jerry|animal=mouse|legs=4}}
| {{Item|name=Tweety|animal=bird|legs=2}}
}}

Constructs available to recipient templates[ਸੋਧੋ]
Get a component of an item[ਸੋਧੋ]
See Template:Component.
Format an item using a template[ਸੋਧੋ]
See Template:Format item.
Format each item using a template[ਸੋਧੋ]
In the recipient template, use:
{{#invoke:Item|each|template=TransformationTemplate|Separator|Prefix|Suffix|...}}
This transforms all items using a given template. TransformationTemplate is called for each item with the parameters that the item has been created with, plus any additional parameters passed to #invokeSeparator and surrounded with Prefix and Suffix (whitespace is not stripped from these three optional parameters).
The template {{User:Petr Matas/sandbox/Pets}} from the example produces the list of pets using the following code (note the use of newline as a Separator and *Prefix to produce list items):
{{#invoke:Item|each|template=Show pet|
|*}}
Gather given parameter from all items[ਸੋਧੋ]
In the recipient template, use {{#invoke:Item|gather|parameter=ParameterName|template=TransformationTemplate}} to gather the given parameter from all items. TransformationTemplate will be called once and the gathered parameters (one parameter from each item) will be passed to it.
The template {{User:Petr Matas/sandbox/Pets}} from the example produces the total number of legs using {{#invoke:Item|gather|parameter=legs|template=Sum}}.
