how to calculate and display an item's age

charlie.elsey · May 20th 2020

A client has e.g. a car site... they need to display a car's current age e.g. car manufactured in 2017 is in 2020 3 years old - yes, that simple output in whole years

If we have the manufactured_date as a field in database what simple code could be used in template to display/output a list of cars with their current ages

many thanks

Hi Charlie,

One option is to write a template filter to calculate the age. Another option is to calculate it with a callback function using the each option:

PHP

perch_content_custom('Cars', [
'each' => function($item) {
// calculate the age from $item['manufactured_date']
// age hard-coded for demonstration
$item['age'] = '3 years';
return $item;
}
]);
