 264      * 1. If the form contains a file upload field, the data does not reach

 266      *    As a workaround I tried jquery.form.js version 2.49. The file
 267      *    upload worked but afterwards the browser presented a tbl_replace.php
 268      *    file and a choice to open or save.
 269      *
 270      * 2. This code can be called if we are editing or inserting. If editing,
 271      *    the "and then" action can be "go back to this page" or "edit next
 272      *    row", in which cases it makes sense to use AJAX. But the "go back
 273      *    to previous page" and "insert another new row" actions, using AJAX
 274      *    has no obvious advantage. If inserting, the "go back to previous"
 275      *    action needs a page refresh anyway.
