In a php generated table, i use drag and drop on the rows, to change the sorting. (first image, second image....)
If i drop the 4th row as first, it will be first, but the row i dropped, it stays as 4th, the rows wont renumber them.
How can i renumber the rows, and put the index in the hidden input named sorrend_hidden?
