Hi,
I want to generate the page title out of the given meta keywords,
separated by the pipe symbol ”|“.
Eg:
[view.yml]
indexSuccess:
metas:
keywords: computer, science, maths
in filters the should be sth. like:
class prepareTitleFilter extends sfFilter
{
public function execute ($filterChain)
{
if ($this->isFirstCall())
{
$response = $this->getContext()->getResponse();
$metas = $response->getMetas();
if ( isset($metas['keywords']) )
{
$this->title = implode(' | ', preg_split('@,\s*@', $metas
['keywords']));
$response->setTitle( $this->title );
}
}
$filterChain->execute();
}
}
My poblem: I can't find the right position in the chain to place my
own filter. Either I can set the page title but can't get the
keywords, or I can read the keywords and it's too late for setting the
title.
An idea, anybody?
