# Idea from https://github.com/mconigliaro/notes/blob/master/wordpress/permissions.md
#
# To use this script run:
# ./fix-wordpress-permissions.sh [CONTAINER]
#

WP_OWNER=www-data               # <-- wordpress owner
WP_GROUP=www-data               # <-- wordpress group
WP_CONTAINER=${1:-'wordpress'}  # <-- container running wordpress

docker compose exec ${WP_CONTAINER} /bin/bash -c " \
      chown --changes ${WP_OWNER}:${WP_GROUP} wp-config.php  && \
      chmod 600 wp-config.php && \
      chown --recursive --changes ${WP_OWNER}:${WP_GROUP} wp-content  && \
      find wp-content -printf '' && \
      find wp-content -type f ! -perm 644 -print0 | xargs --no-run-if-empty --null chmod --changes 644 && \
      find wp-content -type d ! -perm 755 -print0 | xargs --no-run-if-empty --null chmod --changes 755 \
