$mysession is blank, you also are setting $_SESSION['ajaxtext'] to an empty variable. You need to put the correct info into $mysession.

So possibly, you can first set the proper information into $mysession, by doing $mysession = $query['row_info'], then you can call it into the textarea. You can debug as well, do print_r($mysession), if it displays NULL or FALSE then it's because nothing has been set, it might even be completely empty. So try doing, $mysession = 'test'; to first see if the forms are being submitted properly. But no matter what when you input data and want it submitted into your db you will need to use <form>.
