DataValidator: is_date () method

Hi guys! Continuing our series of posts on the DataValidator class , today we are going to address the is_date () method , which, as the name says, is a function for validating fields of type Data (or Date if you prefer) .

The method is very flexible because it allows the validation of both instances of the DateTime class and a date (including time) in a specific format defined by the user.See a validation using an instance of the DateTime class.

ini_set('default_charset','UTF-8');    
include 'DataValidator.php';
 
$validate = new Data_Validator();
 
$date = new DateTime;
 
$validate->set('date', $date)->is_date();
 
if($validate->validate()){
    echo 'Thats ok!';
}
else{
    print_r($validate->get_errors());
}

Now see that if you don’t want a DateTime object, you can pass a certain date and inform via parameter which format it should obey.

$date = '12/31/2013'; //Date in format m/d/Y
$validate->set('date', $date)->is_date('m/d/Y');
 
if($validate->validate()){
    echo 'Thats ok!';
}
else{
    print_r($validate->get_errors());
}

Now let’s look at a time validation in the format HH: mm: ss (Tip: Feel free to pass returns from the date () function as parameters).

$date = date('H:i:s'); //Get the current time in the format HH:mm:ss
$validate->set('date', $date)->is_date('H:i:s');
 
if($validate->validate()){
    echo 'Thats ok!';
}
else{
    print_r($validate->get_errors());
}

Well, I believe that’s it.
