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.
Examples¶
Single alias:
<f:alias map="{x: 'foo'}">{x}</f:alias>
Output:
foo
Multiple mappings:
<f:alias map="{x: foo.bar.baz, y: foo.bar.baz.name}">
{x.name} or {y}
</f:alias>
Output:
[name] or [name]
depending on {foo.bar.baz}
Note: Using this view helper 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).
