What i want to achieve is to get dates through get_post_meta and push them in array and passing it into js code. But when i use below code first post in loop's dates gets formatted and other posts dates showing 01-01-1970. Working since 5 hours any help will be appreciated.

Here is wordpress the code.


function bpem_event_calendar_tab() {

global $bp;

if (isset($bp->groups->current_group->slug)) {


'name' => 'Event Calendar',

'slug' => 'events-calendar',

'parent_slug' => $bp->groups->current_group->slug,

'parent_url' => bp_get_group_permalink($bp->groups->current_group),

'screen_function' => 'bpem_event_calendar_roup_show_screen',

'position' => 90));



add_action('wp', 'bpem_event_calendar_tab');

function bpem_event_calendar_roup_show_screen() {

//add_action('bp_template_title', 'ev_new_group_show_screen_title');

add_action('bp_template_content', 'bpem_event_calendar_group_show_screen_content');

$templates = array('groups/single/plugins.php', 'plugin-template.php');

if (strstr(locate_template($templates), 'groups/single/plugins.php')) {

bp_core_load_template(apply_filters('bp_core_template_plugin', 'groups/single/plugins'));

} else {

bp_core_load_template(apply_filters('bp_core_template_plugin', 'plugin-template'));



/*function ev_new_group_show_screen_title() {

echo 'New Tab Title';


function bpem_event_calendar_group_show_screen_content() {
$group_name =  sanitize_title(bp_get_current_group_name());
$event_data = array();

$args = array(
'post_type'      => 'bpem_event',
'posts_per_page' => -1,
/*   'meta_key'          => 'evn_group_slug',
'meta_value'     => $group_name,*/

$event_query = new WP_Query( $args );
if ( $event_query->have_posts() ) : while ( $event_query->have_posts() ) :       

$start_date = get_post_meta( get_the_id(), 'evn_startDate');
$start_d = date("Y-m-d", strtotime($start_date[$i]));
//echo $start_d.'<br>';

$start_time =   get_post_meta(get_the_id(), 'evn_startTime');
$start_t    =   date("H:i:s", strtotime($start_time[$i]));

$end_date = get_post_meta( get_the_id(), 'evn_endDate');
$end_d = date("Y-m-d", strtotime($end_date[$i]));
//echo $end_d;

$end_time = get_post_meta(get_the_id(), 'evn_endTime');
$end_t = date("H:i:s", strtotime($end_time[$i]));

$event_data[] = array(
'title'         =>  get_the_title(),
'start'         =>  $start_d.'T'.$start_t,
'end'           =>  $end_d.'T'.$end_t
//'end_date'        => $enddate[0]
$json = json_encode($event_data);

echo "<div id='bpem-calendar'></div>";


<script type="text/javascript">

jQuery(document).ready(function() {
var todayDate = jQuery.datepicker.formatDate('yy-mm-dd', new Date());
header: {
left: 'prev,next today',
center: 'title',
right: 'month,agendaWeek,agendaDay'
defaultDate: todayDate,
businessHours: true, // display business hours
editable: false,
events:<?php echo json_encode($event_data); ?>




} ?>

This is the output.

[{"title":"JSON Expert Meetup","start":"2019-03-25T07:00:00","end":"2019-03-27T09:30:00"},{"title":"WordPress MeetUp Karachi","start":"1970-01-01T00:00:00","end":"1970-01-01T00:00:00"},{"title":"WP Meetup Karachi","start":"1970-01-01T00:00:00","end":"1970-01-01T00:00:00"},{"title":"JQuery Masters Meetup","start":"1970-01-01T00:00:00","end":"1970-01-01T00:00:00"}]

  • I don't think you want $start_date[$i]. You probably are looking for $start_date[0]. I would check out what $start_date looks like. – MikeNGarrett Mar 25 at 13:07
  • Bundle of thanks mike problem solved and yes that was the issue thumbs up. – Zaheer Abbas Mar 25 at 13:18

I don't think you want $start_date[$i]. You probably are looking for $start_date[0]. That's why you're only getting the first result and none of the following results. 1970-01-01T00:00:00 is the epoch time and shows up because strtotime() cannot convert the date you're giving it, so that's what it returns by default.

I would check out what $start_date looks like.
