比较今天的发布日期get_the_date（）-Wordpress

Question

I want to be able to calculate the days that post was created and compare with today to echo "Today/ Yesterday/ Last Week/ Last Month". The date format I get from get_the_date() is "December 1, 2015" so I'm wondering if I need to use a different function that I don't know about.

Answer 1

You just need to the get_the_date() function;

Now Date Should In YYYY-MM-DD Format

for that

$date1 = date('Y-m-d', strtotime(get_the_date())) ;
$current_date1 = date('Y-m-d', time()) ;

Now use this function

function dateDifference($date_1 , $date_2 )
{
    $datetime1 = date_create($date_1);
    $datetime2 = date_create($date_2);

    $interval = date_diff($datetime1, $datetime2);

    return $interval->format('%a');

}

//call above function
echo $days = dateDifference($date1, $current_date1);

Answer 2

I'm not sure if there is any WordPress function but you can get your values using built in PHP functions.

Yesterday:

date('Y-m-d', strtotime("-1 day"));

Last week

date('Y-m-d', strtotime("-1 week +1 day"));

Last month

date('Y-m-'.1, strtotime("-1 month")); //First day of -1 month

You can read more about strtotime here http://php.net/manual/en/function.strtotime.php

Here is also a link to the date function, if you havent had any experience with it before: http://php.net/manual/en/function.date.php

You would want to use Ymd format for wordpress querys read more about that here: http://php.net/manual/en/function.date.php
