great model

Really nice idea :)

Btw: The first two links do not work.

Thanks,

I was going to "port" this to Cake is ones I got some free time on my hands, but I guess this isn't necessary any more! :)

[...] ThinkingPHP » Remember the days before spam? A CakePHP Model for Akismet Felix Geisendörfer has implemented an Askimset spam filter helper for CakePHP (tags: cakephp spam helper) [...]

Wouldn't Akismet be better implemented as a component? Also it need not depend on the web model which in turn depends on curl extension

Writing a private method for doing an http post using sockets specifically for akismet would be trivial and make the component self contained....

Here is the code for a similar function I wrote for some other software

function pp_http_post($request, $host, $path, $port = 80) {
global $pp_user_agent;

$http_request = "POST $path HTTP/1.0\r\n";
$http_request .= "Host: $host\r\n";

$http_request .= "Content-Type: application/x-www-form-urlencoded; charset=utf-8\r\n";

$http_request .= "Content-Length: " . strlen($request) . "\r\n";

$http_request .= "User-Agent: {$pp_user_agent}\r\n";

$http_request .= "\r\n";

$http_request .= $request;

$response = '';

if( false !== ( $fs = fsockopen($host, $port, $errno, $errstr, 30) ) ) {
fwrite($fs, $http_request);

while ( !feof($fs) )
$response .= fgets($fs, 1160); // One TCP-IP packet

fclose($fs);

$response = explode("\r\n\r\n", $response, 2);

}

return $response;
}

This in turn has been adapted from the code in word press

Odd, the "official" akismet plugin replies true or false. your model returns true or 1.
so for those that don't know, that means you need to type === true if you want to check if it's spam (the extra = is for type check)

Also, i wonder what happens in case of unreachable/unresponding askismet servers? i noticed the use of a timeout variable in your web_model. is it safe to assume that if there is no response in this time the askismet-checking aborts and the logic continues to process? and in that case, what will be returned?

Offcourse that's okay :-)

Okay what i said wasn't 100% correct.
After some testing i found out that what is really returned is this:

'true' (the string, not the boolean), when the hit is true

true (the boolean) when the hit is false

i thought earlier that 1 was also an option but i was mislead cause 1 is what you see when you echo(true);

so to be really sure about the result, this is how i check:
if($is_spam === 'true') echo 'spam';

if($is_spam === true) echo 'not spam';

Still i would love to hear more from you felix, especially about the question what will happen in the case of the unreachable/unresponding askismet server :)

Hey thanks a million!

I'm successfully using Akismet through your models and I really really really want to thank you! You saved me...

On reading your post I had the same thoughts on looking further for a component. Thanks for the explanation on why the code should be a model and not a component. It all makes sense now.

Thanks a lot for this, I'm testing it right now. Lol, kind of ironic to see a spam comment turn up here then, I guess akismet isn't perfect but yeah there is no perfect solution against spam right..
