Question

$my_post = array(

how to make post auto post when the date today (or older day) and auto schedule when the date tomorrow ?
ps: for today (or older day) maybe that code will work correctly but how to do it for auto schedule when i put the date tomorrow or next day (if it possible please give sample code)
update question: what i mean is how to make wp_insert_post make a schedule post when the date set to the future (next day/next month/next year or specific date) because when i try to set 'post_date' => "2015-08-30" the post keep post with today date what i want is that post will create as schedule post
thanks

Answer 1

To test if the date is for tomorrow, try something like this :
$tomorrow = date('Y-m-d', strtotime('tomorrow'));
And for the day after tomorrow :
$day_after_tomorrow = date('Y-m-d', strtotime('tomorrow + 1 day'));
Then you can test $date:
if ($date == $tomorrow) {
echo "tomorrow";
} elseif ($date == $day_after_tomorrow) {
echo "dayaftertomorrow";
}
Updated answer :
Basically post_date is for the time post was made and if you want hack i think that you need to have date in this format : [ Y-m-d H:i:s ]

Answer 2

The post datetime is [ Y-m-d H:i:s ], try it:
<?php
$timezone_offset = get_option( 'gmt_offset' );
$post_date = date_create( "2014-07-30" );
$post_date_gmt = date_create( "2014-07-30" );
$post_date_gmt->add( new DateInterval( "PT{$timezone_offset}H" ) );
//today date 2014-07-27
$title="title";
$content="content";
$date="2014-07-30";
$my_post = array(
'post_title' => $title,
'post_content' => $content,
'post_status' => 'post',
'post_date' => $post_date->format('Y-m-d H:i:s'),
'post_date_gmt' => $post_date_gmt->format('Y-m-d H:i:s'),
'post_author' => 1
);
$post_id = wp_insert_post( $my_post );
?>
Enjoy your code
