That's a PHP feature :)
-------------------------------------
> php -r "var_dump('0' == 'AR');"
bool(false)
> php -r "var_dump(0 == 'AR');"
bool(true)
----------------
If the first operand of comparison operator is integer then the second
is converted to integer. (int)'AR' is int(0).
With best regards,
Alexander Veremyev.

Subject: [fw-general] Custom Validator, '0' == 'AR' is true ???
Hi all. I have this validator:
class validator_selectChoice extends Zend_Validate_Abstract
{
const SELECTCHOICE = 'selectChoice';
/*
* Rappresenta il valore di default che non deve essere quello
scelto dall'utente.
*/
private $_errorValue;
protected $_messageTemplates = array(
self::SELECTCHOICE => "You need to choice a value"
);
public function __construct($err = 0) {
$this->_errorValue = $err;
}
public function isValid($value)
{
$this->_setValue($value);
var_dump("E: $this->_errorValue");
var_dump("V: $value");
if ($value == $this->_errorValue) {
var_dump("iF!!!!!!!!!!!!!!!!!!!!");
$this->_error();
return false;
}
return true;
}
}
This is the debug log (via var_dump output)
string 'E: 0' (length=4)
string 'V: AR' (length=5)
string 'iF!!!!!!!!!!!!!!!!!!!!' (length=22)
string 'E: 0' (length=4)
string 'V: 5' (length=4)
string 'E: 0' (length=4)
string 'V: 1' (length=4)
Why '0' == ' AR' is true ?
Tnx.
