WP 2.6 allows sites to move the wp-content
directory around, so plugin developers like me can’t depend on them being in a predictable location. We can look to the WP_CONTENT_DIR
and WP_PLUGIN_DIR
constants for answers, but a better solution is likely to use the X_url()
functions. The most useful of those is likely to be plugins_url()
. Even better, you can give these functions a relative path and they’ll return a fully qualified URL to the item.
