Question

Getting the following error:

Warning: date() expects parameter 2 to be long, string given in /home/15063/brooks/www.brooks-shopping.co.uk/public_html/wp-content/themes/sandbox/functions.php
on line 546

Which points to the line:

$day = date("l, F jS", get_post_meta($post->ID, 'date_value', true));

Can someone suggest, what changes are required to the above line to resolve this please?

Answer 1

Date expects parameter 2 to be a long. i.e. it expects a number to be returned.

You return a string (assuming) with get_post_meta
You need to convert it to a time first before you can return it (a date long)

Instead try

$day = date("l, F jS", strtotime(get_post_meta($post->ID, 'date_value', true)));

The strtotime function return an int as shown here
