I added the following:
$mode=(isset($_GET['mode']))?($_GET['mode']) : "" ;
$id=(isset($_GET['id']))?($_GET['id']) : "" ;
$name=(isset($_GET['name']))?($_GET['name']) : "" ;
$phone=(isset($_GET['phone']))?($_GET['phone']) : "" ;
$email=(isset($_GET['email']))?($_GET['email']) : "" ;
$info=(isset($_GET['info']))?($_GET['info']) : "" ;
The only error message I get now is "PHP Warning: Module 'mysql' already
loaded in Unknown on line 0." However, add, edit still don't work. I
receive an error message saying page can't be displayed and the url shows
PHP_SELF (it shows the correct directory before that). Should I change
***************
Print "<td><a href=" .$_SERVER['PHP_SELF']. "?id=" . $info['id'] ."&name=" .
$info['name'] . "&phone=" . $info['phone'] ."&email=" . $info['email'] .
"&mode=edit>Edit</a></td>";
Print "<td><a href=" .$_SERVER['PHP_SELF']. "?id=" . $info['id']
.."&mode=remove>Remove</a></td></tr>";
**************
too? I assume this is where the url is derived?
I'll post my current script, just in case I've done something wrong. Thanks
again. Robert
