Ok, so I have a table in my admin area for my plugin. Each row as an edit button, which should post to the edit page. I don't know how to add my php edit page to the registered wordpress page, though, so I don't know what to put for action in the form.
<td><form action="[edit.php]" method="post"> <input type="hidden" id="<?php echo $issue->id?>" name="id" value="1"> <input type="submit" value="Edit"> </form> </td>
So what should I put inside the brackets (and yes, I will remove the brackets), and where/how do I add edit.php so wordpress knows it exists?
UPDATE: So apparently I just add edit.php normally, but specify null for its parent. Stil no idea what to put in those brackets.
UPDATE 2: Apparently the function I was looking for was menu_page_url...
