Scheduled Posts Feature

[taufik-nurrohman]

The idea is to compare two given dates where the first date is the current date and the other is the future date:

$now = $_SERVER['REQUEST_TIME'];
$schedule = strtotime('2030-12-04 15:30:00');

if ($schedule - $now <= 0) {
    // Publish the post!
}

Store the schedule date in a property other than time (let’s say schedule) and then save the associated page as draft:

---
title: Sceduled Post
description: This post will be published in the future.
schedule: 2030-12-04 15:30:00
...

Lorem ipsum dolor sit amet.

Save it as .\lot\page\article\scheduled-post.draft.

To monitor the publication schedule, you will need to loop through the contents of .\lot\page\article folder to compare the schedule date value with the current date value. If the criteria has been met, change the page file extension from .draft to .page, and add time data to the associated page file if necessary:

$now = $_SERVER['REQUEST_TIME'];
foreach (g(LOT . DS . 'article', 'draft') as $k => $v) {
    $v = new Page($k);
    if (!$v = $v->schedule) {
        continue;
    }
    $schedule = strtotime($v);
    if ($schedule - $now <= 0) {
        $folder = dirname($k) . DS . pathinfo($k, PATHINFO_FILENAME);
        rename($k, $folder . '.page');
        if (!is_dir($folder)) {
            mkdir($folder, 0755, true);
        }
        file_put_contents($folder . DS . 'time.data', $v);
    }
}

Another way is to store the schedule data separately from the page. I didn’t check the performance but it should be more efficient than the above method because we can take off the YAML parser tasks just to get the schedule data:

$now = $_SERVER['REQUEST_TIME'];
foreach (g(LOT . DS . 'article', 'draft') as $k => $v) {
    $folder = dirname($k) . DS . pathinfo($k, PATHINFO_FILENAME);
    if (!is_file($file = $folder . DS . 'schedule.data')) {
        continue;
    }
    $schedule = strtotime($v = file_get_contents($file));
    if ($schedule - $now <= 0) {
        rename($k, $folder . '.page');
        file_put_contents($folder . DS . 'time.data', $v);
        unlink($file); // Remove the `schedule.data` file (optional)
    }
}
