Warning: date() expects parameter 2 to be long...

[mat3osz]

Hi!
I need some help with PHP.

A few days ago I installed the plugin into Wordpress.

Everything worked, but today an error occurred.

Warning: date() expects parameter 2 to be long, string given in /home/wp-content/plugins/upcoming-events-lists/upcoming-events-lists.php on line 211

 

Line 210 and 211:

$start_date = get_post_meta( $post_id, 'event-start-date', true );
echo date( 'F d, Y', $start_date );

Can somebody be so kind as to tell me what I need to change to resolve this?

I need to fix this ASAP ;/ 

Thanks.

start_date is apparently NOT an integer, ie, a time value.  You need to do a strtotime() on it before trying to format it is a viewable date/time value.

The date() function expects a Unix timestamp (i. e. an integer) as the second parameter. See the PHP manual.

 

Your $start_date is appearently not a Unix timestamp. It may be a MySQL DATE which must be parsed before it can be converted. There may be a WordPress function for it. Otherwise you'll have to parse the date yourself and then reformat it.

<?php

const MYSQL_DATE_FORMAT = 'Y-m-d';



$input = '2016-08-30';
echo DateTime::createFromFormat(MYSQL_DATE_FORMAT, $input)->format('F d, Y');
