Syntax #

From lib/eztemplate/classes/eztemplateswitchfunction.php:

{switch match=$node.class_identifier}
{case match='article'}
    <span class="badge">{'Article'|i18n( 'design/mytheme' )}</span>
{/case}
{case match='event'}
    <span class="badge">{'Event'|i18n( 'design/mytheme' )}</span>
{/case}
{case}
    {* no match: the case without a match is the default *}
{/case}
{/switch}

The media design's title template uses a switch on the error type and number to name error pages.

Matching several values #

{case in=array( 'article', 'blog_post' )}
    ...
{/case}

A condition #

{case} compares values only (match or in). A process= parameter appears in the class's comment as a TODO and is not implemented. For a range or any other condition, use {if}:

{if gt( $children|count, 5 )}
    ...
{else}
    ...
{/if}

When not to use it #

• Per content class markup belongs in override templates, not in one big switch (Node templates by class).
• Two branches are clearer with {if}.
