Thread: Show age from date of birth custom fields.

Show age from date of birth custom fields.

Hi,

I have created 3 custom fields with drop down lists with years, months, days all with a numerical value:

cp_yearofbirth (1900 - 2020)
cp_monthofbirth (01 -12)
cp_dayofbirth (01-31)

By editing the single-ad_listing.php I can show any or all of the fields by using:

<?php echo get_post_meta($post->ID, 'cp_yearofbirth', true); ?> and changing the value.

What I would like to do is use these 3 custom fields to calculate the age of the poster and display it. I know I will have to put the code into the single-ad_listing.php file which is fine as the whole file will be customised anyway.

Does anyone know the code I need to do this?

Thanks, Mark
