I have a custom post type product using ACF (Advanced Custom Fields)

I would like to schedule a daily cron task automation to export all published posts into post_id.txt, one for each post.

I know there are plugins that can export custom post type and ACF to CSV or XML.

But my requirement is a more customized task.

A simplified example, the format of the output file post_id.txt should be and each field separated by \n:

eg. 1234.txt

POST_TITLE
PRODUCT_IMAGE(ACF URL FIELD)
CATEGORY
TAGS
CONTENT

I can access all these information in the template loop, but how do I write a function to export them as the above job requirement?

Any pointer and direction of where to begin is appreciated.

Schedule your backup with WP Cron - https://codex.wordpress.org/Function_Reference/wp_schedule_event

In the cron event, run your query for posts or CPTs and be sure to add 'numberposts' => -1, to return all.

When you loop through your posts from the resulting query, push the values to an array $data[]=$some_string_data_for_prop;

And when you're ready to write the data, convert the array values to a single string; $output = implode("\n", $data);

Then write the data to a file file_put_contents($filepath, $output);

  • All the steps make sense to me. I'm using a W3 Total Cache and I use the system cronjob for my wp-cron execution to ensure it's running at my scheduled time. The thing I'm not sure is where do I put the actual code? In my template file or in functions.php? Or can I create a separate .php file for this task or even making it a dedicated plugin? In this case, how do I use the Wordpress functions if it's a standalone file? – KDX Aug 8 '16 at 2:05

    It's tricky, you can put it in functions.php but you really only want to turn on/off the event. It's probably best to make it as a plugin (since it's not theme related) and have a button that starts/stops the process. – jgraup Aug 8 '16 at 2:08
  • Yes, it's unrelated to theme but I find the theme's loop is the easiest to implment. I understand the logic here, just not sure where do get started. Any pointer to instruction on writing a simple basic plugin? – KDX Aug 8 '16 at 2:16

    Plugins are pretty easy. It's a file with the same name as the folder in /wp-content/plugins/your-plugin/your-plugin.php - wppb.me - codex.wordpress.org/Writing_a_Plugin – jgraup Aug 8 '16 at 3:22
