Finaly something from Statik that Ray was happy with!

Oh btw, we need a PHP forum. Make Ray the moderator.

[Statik]

lol @ PHP forum

[Ray]

I'm always happy that Statik helps me, I think we just suffer from that "neither of us are native English speakers" issue, so we never understand what the other really means.

That might be just my poor explanation and phrasing though.

I am completely clueless over validating 0 as integer. I am trying to validate user input in the range of 0 to 2. The user input is given to a function like this:

Code: [Select]

(int)mysql_real_escape_string(filter_var(trim($_POST['score']), FILTER_SANITIZE_NUMBER_INT))
Now inside the function, I even checked it to be exactly 0 like this:

Code: [Select]

if ($score === 0) echo 'something';
That worked. However... in the validation process, it's not working, probably because the FILTER_VALIDATE_INT filter does not validate 0 as an integer, even though I did everything for it to accept it as an integer. Values 1 and 2 are accepted by this:

Code: [Select]

filter_var($score, FILTER_VALIDATE_INT, array('options' => array('min_range' => 0, 'max_range'=> 2 )))
Anyone can tell me why this validation fails for the value 0?

EDIT: found out 0 is handled as empty for some reason.

I'm far away from excellent English, but thank you, that feels nice from a native speaker. Yes, Statik always has an answer and he is a great coder, no doubt about that, I'm just usually looking for something else, not what he thinks and I meant that if I was Russian and I could ask him in our native language, he would give me the exact answer I'm looking for.

Why so much trouble for a range Ray?

Code: [Select]

if (in_array(trim($_POST['score']), range(0, 2)))
    //do stuff.


[Statik]

Hey MI, you are wrong (!), try to set $_POST['score'] to "2a", "a2", "bbb", etc.

For Ray (less words, more links!):

http://php.net/manual/en/function.filter-var.php (NOTE: Returns the filtered data, or FALSE if the filter fails.)

Solution: http://www.cleancode.co.nz/blog/664/filter_validate_int-0

[Statik]

Wasn't sure if I should write this... but simple regular expression is shorter and cleaner way to validate integer:

Code: [Select]

if (preg_match('/^[0-2]$/', $score))
    ...

Interesting theme

Btw don't we have a C/C++ topic? Because I need help in Visual C++ xD

Btw the website looks cool Ray!

Statik he simply wants to validate the POST data to see whether it is one of the 3 values or not. I highly doubt if he wants to get "2" from "2a".

Exactly, but when you use in_array() without the 3rd parameter set to true, the comparison is not strict, it means 2 == '2a' and 0 == 'abbbdd2'. Maybe smth like that will work tho: in_array($_POST['score'], array('0', '1', '2'), true), I didn't check.

No offense, Ray. Was just a funny answer after all that code stuff.
