Switch ViewHelper <f:switch>
Note
This reference is part of the documentation of Fluid Standalone. If you are working with Fluid in TYPO3 CMS, please refer to TYPO3's ViewHelper reference instead.
Switch ViewHelper which can be used to render content depending on a value or expression.
Implements what a basic PHP switch() does.
An optional default case can be specified which is rendered if none of the
case conditions matches.
Using this ViewHelper can be a sign of weak architecture. If you end up using it extensively
you might want to consider restructuring your controllers/actions and/or use partials and sections.
E.g. the above example could be achieved with <f:
and the partials "title.male.html", "title.female.html", ...
Depending on the scenario this can be easier to extend and possibly contains less duplication.
Examples
Simple Switch statement
<f:switch expression="{person.gender}">
<f:case value="male">Mr.</f:case>
<f:case value="female">Mrs.</f:case>
<f:defaultCase>Mr. / Mrs.</f:defaultCase>
</f:switch>
Output:
"Mr.", "Mrs." or "Mr. / Mrs." (depending on the value of {person.gender})Go to the source code of this ViewHelper: SwitchViewHelper.php (GitHub).
