Item Publisher

The item publisher app lets you publish items on your website.

Using this app you can:

  • Select a type of item to publish
  • Control how the items are rendered in frontend
  • Set up filters, to further control which items to publish
  • Enable or disable frontend-editing of items

Before you can use the item publisher app you need to have one or more item types defined, and you need to have one or more items created. 

Using the app settings (Figure 2.1) you control which items and item fields you want to publish.

Figure 2.1 The Item Publisher data settings

Here you can:

  • Select the item type you want to publish
  • Select the area you want to publish items from. Your options are:
    • Select items from this language/area – publish items from a specific website
    • Select items from current language/area – publish items from the website with the app attached
    • Select items under the current page – publish all items under current page (the page with the app attached)
    • Select items under the following pages – publish items from one or more pages.
    • Select specific item(s) – publish specific items from the item repository.
    • Named item list – publish items from a named item list
  • Include paragraph items – also publish the paragraph items belonging to the pages you publish
  • Include child items – publish all items (children, grandchildren, and so on) under the selected page/website.
  • Include inherited items – publish all items inherited from a base item type. Available from 8.6.1.0
  • Show login for restricted items – list restricted pages, but require login for accessing the details
  • Item fields – lists: Specify which item fields you want to show in the list view when publishing items
  • Item fields – details: Specify which item fields you want to show in the details view when publishing items

The list settings (Figure 3.1) control how you render lists of items.

Figure 3.1 The Item Publisher list settings

Here you can:

  • Select the template you want to use for the list view
  • Specify a sort order
  • Select you list view type
    • Normal provides you with ordinary paging. Write the number of items you want on a page in the Page Size field.
    • Partial provides you with the option of selecting a partial list of items to show – enter the item to start from in the item from and the item to end with in item to field
  • Specify a page size in items

The details settings (Figure 4.1) control how you to render the details view of each list item. 

Figure 4.1 The Item Publisher details settings

With the details settings you:

  • Create or select a template
  • Specify the paragraph you want to display the details view on, when a user clicks view or edit on an item – the selected paragraph needs to also have the item publisher app attached, with the same item type selected.

If you're publishing page items, you don't need to use the details template at all. You can link directly to the page instead.

With the filter settings, you can set up conditions (rules) in order to limit the subset of items published.

Figure 5.1 You can filter the items before publication by creating filtering rules

To set up a rule:

  • Click add new rule
  • Choose a field to filter on
  • Add a condition and a value to test for
    • Conditions available: is/is not, contains/does not contain, starts with/does not start with, and ends with/does not end with
    • You may choose between the operators AND and OR when combining your filtering rules.

You can use values from the context to control which items are published:

    @Request() – get value from System.Web.HttpContext.Current.Request
    @Session() – get value from System.Web.HttpContext.Current.Session
    @Page() – get value from current Page object, if any. (Current page exists if a valid PageID is in the query string).
    @User() – get value from the current User object.
    @Code() – evaluate C# code
    @Paragraph() – get value from current paragraph object, if any. (Current paragraph exists if a valid ParagraphID is in the query string).
    @ProductID() – get value from current product object, if any. (Current product exists if a valid ProductID is in the query string).

Examples:

    @Page(MenuText) – Get title of page
    @User(Name) – get name of user
    @User(Email) – get email of user
    @Code(System.DateTime.Now.AddDays(1)) – get tomorrow’s date
    @Code(1+2) – get 3 (possible, but stupid, granted)

Finally, the Edit settings allow you to enable frontend editing of items, and the error messages settings allow you to customize the errors shown when users try to save empty or invalid field entries.

Figure 6.1 Enable frontend editing of item fields by using these settings

With the edit settings you can:

  • Enable editing of item fields in the frontend
  • Select the template you want to use for the edit page

With the error messages settings you can:

  • Specify the error message on an incorrect field value used
  • Specify the error message on an empty field

The Item Publisher supports query string filtering.

System type string fields can be filtered using the following operators: 

Example Filtering effect
Name=Razor Exact match
Name=t* Starts with
Name=*t* Contains
Name=*t Ends with

System type numeric fields can be filtered using the following operators:

Example Filtering effect
Number=10 equals
Number=10&Number.op== equals (operator specified)
Number=10&Number.op==eq equals (operator specified)
Number=10&Number.op=!= not equal to
Number=10&Number.op=<>  not equal to
Number=10&Number.op=< less than
Number=10&Number.op=<= less than or equal to
Number=10&Number.op=> greater than
Number=10&Number.op=>= greater than or equal to
Number.from=10&Number.to=20 range (explicit)
Number=10-20 range (implicit)
 

System type double fields can be filtered using the following operators:

Example Filtering effect
Double=0&Double.op=lt less than
Double=0&Double.op=gt greater than

System type date fields can be filtered using the following operators:

Example Filtering effect
DateAndTime=2014-08-01 equal
DateAndTime=2014-08-01&DateAndTime.op=<  before
DateAndTime=2014-08-01&DateAndTime.op=lt  before
DateAndTime=2014-08-01&DateAndTime.op=> after
DateAndTime=2014-08-01&DateAndTime.op=gt after
 
DateAndTime.from=2014-08-01&DateAndTime.to=2015-08-01 range (explicit)

Other useful parameters are:

Parameter Effect
PageSize Forces a pagesize. Overrides the page size defined in the item publisher settings.
orderby=[field] Selects a field to sort by
orderby2=[field] Select an additional field to sort by
direction=[ASC/DESC] Selects a sort direction
direction2=[ASC/DESC] Selects an additional sort direction

Finally, you can also override (or set) most of the app settings from the query string:

  • ItemType
  • IncludeParagraphItems
  • IncludeAllChildItems
  • IncludeInheritedItems
  • sourceArea
  • sourcePage
  • SourceItemEntry
  • SourceItemEntries
  • sourceType
  • ListTemplate
  • DetailsTemplate

 

The Item publisher extension tags - Item.Render/RenderItem() & Item.RenderList/RenderItemList() - are methods to render an item directly in a template without the use of a page or paragraph.

For example:

Example 1: string DataFromItem = RenderItemList(new { ItemType = "NameOfMyItem", ListSourceType = SelfPage, ListSourcePage = "3223", ItemFieldsList = "*", ListTemplate = "ItemPublisher/ListMyItems.cshtml", ListPageSize = "100", }); @DataFromItem Example 2 - Multiple SourcePages string DataFromItem = RenderItemList(new { ItemType = "NameOfMyItem", ListSourceType = SelfPage, ListSourcePage = "3223, 1432, 3421", ItemFieldsList = "*", ListTemplate = "ItemPublisher/ListMyItems.cshtml", ListPageSize = "100", }); @DataFromItem Example 3 - Using a filter @{ var areaId = GetInteger("…"); if (areaId > 0) { @RenderItemList(new { ItemType = "Contact", ListSourceType = "SelfArea", ItemFieldsList = "*", ListTemplate = "ItemPublisher/List/List.cshtml", ListPageSize = 10, ListOrderBy = "Name", Filter = "Areas contains \""+areaId+"\"" }); } }
