[Résolu] Days to go for future date calculation (Future Date – Now).

I created a shortcode in my functions.php and added it to views. Then on a page I added the shortcode itself as [wedding_countdown users='[wpv-current-user info="id"]'] so that only looking at the current user... but my calculations are huge... so my maths must be off or have I got something else wrong.

I want to calculate between a custom user field (wedding date) and today's date. The custom field will be in the future so I'm counting down in days.

i.e
Wedding Date = 30/01/16
Today's Date = 23/01/16
Result = Only 7 days to go!

/** Custom Countdown Shortcode
 */

function custom_date_countdown_shortcode ( $atts ) {
   global $post;
 
   $timestamp = get_post_meta( $post->ID, 'wpcf-wedding-date', true );
   $timeleft = $timestamp - mktime();
   return round ($timeleft/(60*60*24));
}
add_shortcode( 'wedding_countdown', 'custom_date_countdown_shortcode' );

Dear lindsay,

As you mentioned above, you are going to output the value of user field, you will try with wordpress function get_user_meta(), for example:

/** Custom Countdown Shortcode
 */
 
function custom_date_countdown_shortcode ( $atts ) {
   $timestamp = get_user_meta( get_current_user_id(), 'wpcf-wedding-date', true );
   $timeleft = $timestamp - mktime();
   return round ($timeleft/(60*60*24));
}
add_shortcode( 'wedding_countdown', 'custom_date_countdown_shortcode' );

More help:
get_user_meta
Retrieve a single meta field or all fields of user_meta data for the given user. Uses get_metadata()

Wow - brilliant, seems so obvious now. Thank you so much for your help though... I will learn from it.

Just added for completeness.

For anyone googling this may be of further help... as once the date has passed would not want to display a minus figure. This will check if the wedding date is after today's date, if it is it will return 'Congratulations...' - if not it will return a message, also containing the number of days to go before the wedding date.

/** Custom Countdown Shortcode
 */

function custom_date_countdown_shortcode ( $atts ) {
   $timestamp = get_user_meta( get_current_user_id(), 'wpcf-wedding-date', true );
   $timeleft = $timestamp - mktime();
   
	$wt_time    =   strtotime($timestamp);
	$cur_time   =   strtotime(now);


	if($wt_time > $cur_time ) {
   		return 'Congratulations to you both.';
	}
		else {
			// do the time left stuff
			return 'Only '. round ($timeleft/(60*60*24)). ' more days to go before your very special day!';
			} 
	}

add_shortcode( 'wedding_countdown', 'custom_date_countdown_shortcode' );
