Variable: Set

Sets a single variable in the TemplateVariableContainer scope. The variable then becomes accessible as {var}.

Combines well with v:var.get to set shorter variable names referencing dynamic variables, such as:

<v:var.set name="myObject" value="{v:var.get(name: 'arrayVariable.{offset}')}" />
<!-- If {index} == 4 then {myObject} is now == {arrayVariable.4} -->
{myObject.name} <!-- corresponds to {arrayVariable.4.name} -->

Note that {arrayVariable.{offset}.name} is not possible due to the way Fluid parses nodes; the above piece of code would try reading arrayVariable.{offset}.name as a variable actually called "arrayVariable.{offset}.name" rather than the correct arrayVariable[offset][name].

In many ways this ViewHelper works like f:alias with one exception: in f:alias the variable only becomes accessible in the tag content, whereas v:var.set inserts the variable in the template and leaves it there (it "leaks" the variable).

If $name contains a dot, VHS will attempt to load the object stored under the named used as the first segment part and set the value at the remaining path. E.g. {value -> v:var.set(name: 'object.property.subProperty')} would attempt to load {object} first, then set property.subProperty on that object/array using ObjectAccess::setPropertyPath(). If {object} is not an object or an array, the variable will not be set. Please note: Extbase does not currently support setting variables deeper than two levels, meaning a name of fx foo.bar.baz will be ignored. To set values deeper than two levels you must first extract the second-level object then set the value on that object.

Using as {value -> v:var.set(name: 'myVar')} makes {myVar} contain {value}.
