BuddyPress.org

The top part of a member profile is in the /members/single/member-header.php template, and each user in the member directory uses the /members/members-loop.php template.

//Calculate someone's age based on a date of birth string

$year = date("Y");  // Get this year as a string, date(string format, [timestamp default: now])

$dobtime = strtotime("04/09/1980"); // Get date of birth as a timestamp

$age = $year - date("Y",$dobtime);  // Take advantage of auto conversion to subtract this year from the year of the DOB

$bday = date("m/d/",$dobtime).$year; // Create a timestamp from their month and day of birth combined with this year

if((time()-strtotime($bday))<0) $age = $age - 1; // Compare their bday for this year to current timestamp and subtract one from the year if their birthday has not occurred yet

Don’t have time to work it out right now. Why dont you just have a profile field asking age?

For now just supply a field title age and then user can enter the number

@kirkslater,
Since you asked it in another thread, here is what you need

Put this function in your functions.php or bp-custom.php

/**
* Get Age from BuddyPress date of Birth
* <a href='https://buddypress.org/community/members/param/' rel='nofollow'>@param</a> string $dob_field_name :name of the DOB field in xprofile, like Dob or Date of Birth
* <a href='https://buddypress.org/community/members/param/' rel='nofollow'>@param</a> int $user_id : the user for which you want to retrieve the age
* <a href='https://buddypress.org/community/members/param/' rel='nofollow'>@param</a> string $format: the way you want to print the difference, look t  for the acceptable agrs
* @return string :the formatted age in year/month
*/

function bpdev_get_age_from_dob($dob_field_name,$user_id=false,$format="%y Years, %m Month(s), %d days"){
if(!$user_id)
$user_id=bp_displayed_user_id ();

$dob_time=xprofile_get_field_data($dob_field_name, $user_id);//get the datetime as myswl datetime

$dob=new DateTime($dob_time);//create a DateTime Object from that

$current_date_time=new DateTime();//current date time object
//calculate difference
$diff= $current_date_time->diff($dob);//returns DateInterval object
//format and return
return $diff->format($format);

}

and Now you can output the age anywhere using

echo "Age".bpdev_get_age_from_dob("DOB Field Name");//display for the displayed user

//or
echo "Your Age".bpdev_get_age_from_dob("DOB Field Name",bp_loggedin_user_id());//display for logged in user

You can pass the Dob field name, user_id and the format in which you want to show the difference.
here is the gist in case the code gets garbled: https://gist.github.com/1257476
Hope that helps.

PS: It will need php 5.3.3 or above.

No problem. glad it helped

@SBrajesh I tried the codes you gave, but
I got an error when put in echo:
Fatal error: Call to undefined method DateTime::diff() in /home/dom/public_html/wp-content/plugins/buddypress/bp-themes/bp-default/functions.php on line 377

Line 377 is this – $diff= $current_date_time->diff($dob);//returns DateInterval object

Any idea how to correct that?
Thanks.

Don’t mind, it is working….

hey there guys how would i be able to show the code

‘ echo “Age”.bpdev_get_age_from_dob(“DOB Field Name”);//display for the displayed user

//or
echo “Your Age”.bpdev_get_age_from_dob(“DOB Field Name”,bp_loggedin_user_id());//display for logged in user’

as a profile field on the users profiles?

Same as before but:

echo $dob->format(‘F, d’);
