alias ViewHelper <f:alias>

Declares new variables which are aliases of other variables. Takes a "map"-Parameter which is an associative array which defines the shorthand mapping.

The variables are only declared inside the <f:alias>...</f:alias> tag. After the closing tag, all declared variables are removed again.

Using this ViewHelper can be a sign of weak architecture. If you end up using it extensively you might want to fine-tune your "view model" (the data you assign to the view).

Examples

Single alias

<f:alias map="{x: 'foo'}">{x}</f:alias>
Copied!

Output:

foo
Copied!

Multiple mappings

<f:alias map="{x: foo.bar.baz, y: foo.bar.baz.name}">
    {x.name} or {y}
</f:alias>
Copied!

Output:

[name] or [name]
Copied!

Depending on {foo.bar.baz}.
