1 Martin Hejtmanek (CTO),
Webinar 11/25/2009 Macros in Kentico CMS Martin Hejtmanek (CTO),

2 Topics Macro types and syntax Localization macros
Context (data) macros QueryString macros Cookie macros Custom macros Path macros Path expressions Macro parameters Macros as the web part properties When to use and not use macros and why

3 Macro types and syntax Syntax – {<type><expression><type>} Type – Single character $ = Localization % = Context (data) ? = QueryString value @ = Cookie value # = Custom macro ^ = Inline control (not covered today) Optional parameters – {<type><expression>[<parameter>]*<type>} Parameter – |(<name>)<value>

4 ResHelper.GetString(“General.Cancel”)
Localization macros {$expression$} - ($ as string) Localization from resources {$General.Cancel$} ResHelper.GetString(“General.Cancel”) In-place localization – {$=<default text>[<translation>]*$> Translation - |<culture>=<text> {$=Hello|cs-cz=Ahoj|de-de=Hallo$} = switch (currentCulture) { case cs-cz: return “Ahoj”; case de-de: return “Hallo”; default: return Hello; }

5 Context (data) macros {%expression%} – (% as data value)
General context macros – [<selector>.]<fieldname> Available when the given context object is available {%CurrentDocument.DocumentName%} – Current doc. name {%IP%} – Client IP address {%CurrentDateTime%} – Datetime.Now Data context macros – [<selector>.]<fieldname> Available only for specific modules or actions {%Path%} – Path property from the web part {%OrderStatus.StatusDisplayName%} – In the invoice No specific API code – Just get the desired data using API …

6 QueryString macros {?expression?} – (? as query)
Available within the page request {?param1?} Request.QueryString[“param1”]

7 Cookie macros {@expression@} – (@ as internet / cookie)
Available within the page request CookieHelper.GetValue(“CMSPreferredCulture”)

8 Custom macros {#expression#} - (# as C# or code)
Not processed by engine, processed by YOUR CODE! {#TimeToEndOfTheWorld#} ~/App_Code/Global/CMS/CMSCustom.cs CMSCustom.ResolveCustomMacro(resolver, “TimeToEndOfTheWorld”, out bool match) public static string ResolveCustomMacro(MacroResolver sender, string expression, out bool match) { if (expression.ToLower() == "timetoendoftheworld“) { match = true; return (new DateTime(2012,12,21).Subtract(DateTime.Now)).ToString(); } else { match = false; return expression; } }

9 Path macros {&expression&} – (& as path)
Resolves AliasPath – See previous webinar {&./Teaser&} – Document named Teaser under current document {&/{1}/{3}&} – First and third level of current document path CMSContext.ResolveCurrentPath(“./Teaser”)

10 Path expressions for macros
. = Current document path (only on beginning) .. = Parent document path (if on beginning, starts from current) {<index>} = Specific part of current document path How to read the path expressions ./Teaser – “Teaser document under current document ../Teaser – “Teaser document under the parent document /Products/{1}/{2} – Document in products section matching the first two levels of current path /Accessories/{1}/% - All accessories within the same main section as current product

11 Macro parameters |(name)value
Culture, Format, Default, Encode, ToLower, ToBool, Equals, … Full list in the documentation – Appendix A {?param1|(default)N/A?} QueryString value of param1 or N/A if not available {%CurrentDocument.DocumentName|(encode)false%} Current document name, never HTML encoded {%CurrentDocument.DocumentName|(encode)true%} Current document name, always HTML encoded

12 Macros in web part properties
All web part properties are resolved unless it is disabled Some of them may be excluded CMSAbstractWebPart.mNotResolveProperties = “;yourproperty1;yourproperty2;”; Some of them may automatically escape SQL injection CMSAbstractWebPart.mSQLProperties = “;wherecondition;orderby;yourproperty;”; Web part property can use data macro to use another property Text = Container title is {%ContainerTitle%} If you need to do some web part setting dynamic, use custom macro

13 When to use and not use macros
Use macros in: Web part properties (even non-text ones) s and other templates Anywhere where it is recommended in the documentation In places where you need to set up something dynamically, it is easier to use macro than Copy – Paste – Change the web part Don’t use macros for: ASPX page templates Transformations Layouts In places where you have direct access to the API, it is more efficient to query the objects directly

14 Q&A Now is the time for your questions
The webinar recording will be available on our new Partner portal and later on the DevNet.
