Functions

check

$v = FormValidator::Simple::Struct->new();
$v->check(111 , "INT"); # return true
$v->check(111 , "STRING"); # return false and $v->has_error is true 
$v->check([111 , 1222, 333] , ["INT"]);# return true
$v->check({ key  => 'value'},{key=> "ASCII"});# return true
$v->check([{id => 111,id2=> 22.2 },{id=> 1222 , id2=> 1.11},{id=> 333 , id2=> 44.44}] , [{id =>"INT",id2 => "DECIMAL"}]);# return true

has_error

$v->check(
  {key =>  "abcdefghijklmnop" },
  {key => ["ASCII","NOT_BLANK" , ['LENGTH' , 1 , 15]]});
if($v->has_error){
    # error handling routine
}

get_error

$v->check(
  {key =>  "abcdefghijklmnop" },
  {key => ["ASCII","NOT_BLANK" , ['LENGTH' , 1 , 15]]});
if($v->has_error){
    use Data::Dumper;
    warn Dumper $v->get_error;
    #$VAR1 = [
    #  {
    #    'min_value' => 1,
    #    'error' => 'LENGTH',
    #    'position' => '$param->{hoge}',
    #    'max_value' => 15,
    #    'param_name' => 'hoge',
    #    'message' => 'LENGTH IS WRONG'
    #  }
    #];
}

INT

# allow integer ; 10 , 0 , -10
ok $v->check(
   {key =>  "1" },
   {key => "INT"});

STRING

# allow all Strings
ok $v->check(
   ["111" , "abcde"],
   ["STRING"]);

ASCII

# allow Arabic number and alphabet and ascii symbols
ok $v->check(
   ["111" , 'abcde!"#$%%()'],
   ["ASCII"]);

# not allow multi bytes characters
ng $v->check(
   [Non-ASCII character],
   ["ASCII"]);

DECIMAL

# allow integer and decimals ; 10 1,0 , 0 , -10 , -1.0
ok $v->check(
   ["111" , "11.1" , "-11" , '0' , '-1.15'],
   ["DECIMAL"]);

URL

# allow ^http|^https
ok $v->check(
   ["http://google.com" , 'https://www.google.com/'],
   ["URL"]);

ng $v->check(
   ["git://google.com" , 'smb://www.google.com/'],
   ["URL"]);

DATETIME

# The following examples are followed. 
ok $v->check([
    '%Y-%m-%d %H:%M:%S',

    '%Y-%m-%d %H-%M-%S',
    '%Y/%m/%d %H-%M-%S',],
['DATETIME']);

# The following examples are followed. 
ok $v->check([
   '%Y-%m-%d',
   '%Y/%m/%d'],
['DATE']);

TIME

# The following examples are followed. 
ok $v->check([
   '%H-%M-%S',
   '%H-%M-%S'],
['TIME']);

LENGTH

# check value length
$rule = ["ASCII","NOT_BLANK" , ['LENGTH' , 1 , 8]];
ok $v->check(['a'] , $rule);
ng $v->check(['abcdefghi'] , $rule);

$rule = ["ASCII","NOT_BLANK" , ['LENGTH' , 4]];
ng $v->check(['abc'] , $rule) # false 
ok $v->check(['abcd'] , $rule) # true
ng $v->check(['abcde'] , $rule) # false 

BETWEEN

# check value 
$rule = ["INT",['BETWEEN' , 1 , 8]];
ok $v->check([1] , $rule) # true
ng $v->check([3.1] , $rule) # false not INT
ok $v->check([5] , $rule) # true
ng $v->check([7.9] , $rule) # false not INT 
ok $v->check([8] , $rule) # true
ng $v->check([9] , $rule) # false, input is over 8
