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
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.
