the name table , have 2 columns id , description. 1 i'm trying here edit description column through php.

pass row's id , not description edit.php script , work better

<?php     while( $row = mysql_fetch_array($res) )         echo "$row[id]. $row[description] <a href='edit.php?edit=$row[id]'>edit</a><br />"; ?>

please dont use mysql_ database extension, deprecated (gone ever in php7) if learning php, spend energies learning pdo or mysqli_ database extensions, and here decide use
