Hello.
I’m trying to update a boolean custom field based on whether a post has ‘expired’.
A post is considered expired when its publish date exceeds 30 days. To check this, I am retrieving the post publish date using get_the_date() and adding 30 days to it. Then I check whether this new date is greater than or equal to the present date.
However, the if statement used to compare the dates doesn’t seem to get triggered at all. I checked a post which was published today, and the Boolean True / False field is false. I checked a post published a year ago, and it’s still false (expected: true).
Can anyone help me figure out what’s going on? If you have any suggestions as to how I can improve this, please feel free to mention it.
Kind regards.
add_filter('acf/load_field/name=is_listing_expired', 'acf_listing_expiry');
function acf_listing_expiry($field) {
$start_date_string = get_field('listing_start_date'); //Get the start date value
$date_format = "Ymd";
$listing_date = DateTime::createFromFormat($date_format, get_the_date('Ymd', null)); //Convert to a DateTime object
$modify_amount = "+" . get_field('days_till_expiry') . " days"; //Get the days till expiry value, minimum value is 2
$new_date = $listing_date->modify($modify_amount); //Get the end date
$current_date = date($date_format);
//Check if the date has reached
if($new_date <= $current_date) {
$field['default_value'] = true;
return $field;
} else {
$field['default_value'] = false;
}
$field['default_value'] = false;
return $field;
}
I have not tested this, but you problem probably stems from the fact that “Ymd” in not a valid input format for DateTime. What I mean is that where you are using get_the_date('Ymd', null)); in this statement $listing_date = DateTime::createFromFormat($date_format, get_the_date('Ymd', null)); is not a valid input value.
