CI4 validation greater_than on date field - pippuccio76 - 04-20-2025
HI ,
can i validate date with grater than ?
this is my validation :
Code:
'data_tour' => [
'label' => 'Data Partenza',
'rules' => 'required|valid_date[Y-m-d]|greater_than[' . date('Y-m-d') . ']',
'errors' => [
'required' => '{field} obbligatorio',
'valid_date' => ' {field} deve essere una data valida',
'greater_than' => ' {field} deve essere maggiore di oggi'.$post['data_tour'].'|'. date('Y-m-d'),
]
],and this is the validation (not passed) :
Data Partenza deve essere maggiore di oggi2025-04-21|2025-04-20
2025-04-21 is bigger than 2025-04-20...

Convert your date into a unix timestamp after validating it once as a valid date and then perform the greater_than validation. Alternatively, you could pass your dates in a specific format 'Ymd' and the comparison would work.
RE: CI4 validation greater_than on date field - pippuccio76 - 04-20-2025
I create a custom rules:
Code:
<?php
namespace App\Validation;
class DateRules
{
/**
* Check if the first date is bigger than the second date.
*
* @param string $today oggi (Y-m-d format).
* @param string $date_to_control data da controllare(Y-m-d format).
* @return bool
*
*/
public function date_bigger_than_today(string $date_to_control)
{
$today = strtotime("now");
$date_to_control = strtotime($date_to_control);
if ($date_to_control > $today) {
return true;
} else {
return false;
}
}solved

PHP Code:
// PHP Method to compare dates
// Declare two dates in different
// format and use DateTime() function
// to convert date into DateTime
$date1 = new DateTime("12-11-24");
$date2 = new DateTime("2011-03-26");
// Compare the two dates
if ( ! function_exists('compareDates'))
{
function compareDates(string $date1, string $date2): string
{
if ($date1 > $date2) {
return $date1->format("Y-m-d") . " is greater than " . $date2->format("Y-m-d");
} else {
return $date1->format("Y-m-d") . " is less than " . $date2->format("Y-m-d");
}
}
}

@pippuccio76 : You do not need to return the booleans true or false, you can return $date_to_control > $today which evaluates to a boolean.
@InsiteFX :Your code is erroneous InsiteFX. The second parameter of the function doesn't have a $ in front of date2, $date1 > $date2 performs a string comparison not a date comparison and finally applying the ->format method to a string throws a fatal exception. This code is exceedingly error prone. As an aside, whenever you're comparing dates you should use the DateTimeImmutable class rather than DateTime.

Wasn.t my code I got it off the web to show him another way of doing it.
Thank you for pointing the error out. All fixed now.
