Description: ------------ Validation of decimal numbers such as ".5" fails, although "0.5" passes. As db engines (in our case Oracle) do not store the leading zero, we get validation failures using DB_DataObject in combination with Validate. Test script: --------------- $testval='-.5'; $test = Validate::number( $testval, array('decimal'=>'.')); var_dump($test); Replacing line 270 of Validate.php with the following two lines gives the expected result: $num_regex = $dec_regex == '' ? "|^[-+]?\s*[0-9]+\$|" : "/^[-+]?\s*(([0-9]+)([$decimal][0-9]+)?)|([$decimal][0-9]+)\$/"; if (!preg_match($num_regex, $number)) { Expected result: ---------------- bool(true) Actual result: -------------- bool(false)
