Hi,
From documentation in Symfony book, chapter 6:
<quote>
The Front Controller's Job in Detail
.
.
7. Activate filters (for instance, if the request needs authentication).
8. Execute the filters, first pass.
9. Execute the action and render the view.
10. Execute the filters, second pass.
11. Output the response.
</quote>
From documentation, it is clear that Filter chain makes multiple
passes. In my case it is making 3 passes. I want my filter to get
executed exactly once every page request. No matter how many passes
filter chain makes before it is rendered.
If I use code like this:
class myFilter extends sfFilter
{
public function execute($filterChain)
{
// Execute this filter only once
if ($this->isFirstCall())
{
//some code here
}
// Execute next filter
$filterChain->execute();
}
}
my filter gets executed 3 times as filter chain have to make 3 passes.
How can make sure that my filter gets executed exactly once, that too in
first pass itself?
