/**
|
|
* Variable assigning ViewHelper
|
|
*
|
|
* Assigns one template variable which will exist also
|
|
* after the ViewHelper is done rendering, i.e. adds
|
|
* template variables.
|
|
*
|
|
* If you require a variable assignment which does not
|
|
* exist in the template after a piece of Fluid code
|
|
* is rendered, consider using ``f:alias`` ViewHelper instead.
|
|
*
|
|
* Usages:
|
|
*
|
|
* ::
|
|
*
|
|
* {f:variable(name: 'myvariable', value: 'some value')}
|
|
* <f:variable name="myvariable">some value</f:variable>
|
|
* {oldvariable -> f:format.htmlspecialchars() -> f:variable(name: 'newvariable')}
|
|
* <f:variable name="myvariable"><f:format.htmlspecialchars>{oldvariable}</f:format.htmlspecialchars></f:variable>
