This method will display cached content if it is available.
If not, it will start caching and would expect an View::endCache
call to end the cache and save the content into cache.
A typical usage of fragment caching is as follows,
php
if ($this->beginCache($id)) {
...generate content here
$this->endCache();
}
| public beginCache ( string $id, array $properties = [] ) : boolean | ||
| $id | string | a unique ID identifying the fragment to be cached. |
| $properties | array | initial property values for [[FragmentCache]] |
| return | boolean | whether you should generate the content for caching. False if the cached version is available. |
public function testCacheDisabled2()
{
$expectedLevel = ob_get_level();
ob_start();
ob_implicit_flush(false);
$view = new View();
$this->assertTrue($view->beginCache('test'));
echo "cached fragment";
$view->endCache();
ob_start();
ob_implicit_flush(false);
$this->assertTrue($view->beginCache('test', ['enabled' => false]));
echo "cached fragment other";
$view->endCache();
$this->assertEquals("cached fragment other", ob_get_clean());
ob_end_clean();
$this->assertEquals($expectedLevel, ob_get_level(), 'Output buffer not closed correctly.');
}
