* 1. If the form contains a file upload field, the data does not reach
* tbl_replace.php. This is because AJAX does not support file upload.
* As a workaround I tried jquery.form.js version 2.49. The file
* upload worked but afterwards the browser presented a tbl_replace.php
* file and a choice to open or save.
*
* 2. This code can be called if we are editing or inserting. If editing,
* the "and then" action can be "go back to this page" or "edit next
* row", in which cases it makes sense to use AJAX. But the "go back
* to previous page" and "insert another new row" actions, using AJAX
* has no obvious advantage. If inserting, the "go back to previous"
* action needs a page refresh anyway.
