I am not sure if this is an issue with Wordpress, PHP or the Attachments Plugin.
I am using the Attachments plugin to save attachments to a post with some meta information. One of which is a caption which is a textarea.
When I put multiple lines separated by a newline character and press Publish, when the page comes up again the contents of the textarea display
\n in the textarea (an actual backslash and the character
n), instead of putting a line break.
I am not sure if this is a PHP configuration issue (maybe something to do with escaping database queries?), or a wordpress issue, or an issue just related to this plugin.
