[PHP] suppressing errors
Hello All,
I am trying to use the "@" symbol to suppress errors returned by a
mysql_query call. This doesn't seem to be working as I get an new page with
the error in it in my browser. Any help with this would be greatly
appreciated.
Here is a snippet of the code I am using
$query = "select user_id from users where username='$username'";
$query_db = @mysql_query($query, $db_connection);
$row = @mysql_fetch_array($query_db);
if($row) {
$message[] = "That username is already taken. Please select
another.";
} else {
Thanks,
Preston

RE: [PHP] suppressing errors
The error is one from mysql stating that I am trying to add a duplicate
entry. I would rather handle this in my code hence the following lines in
my code.
if($row) {
$message[] = "That username is already taken. Please select
another.";
} else {
Thanks for the response.
Thanks,
Preston

[PHP] isset
Hello All, I am trying to use the isset function to test if the page has been submitted, but it seems as though it is not working. I am wondering is there a configuration option that is messing with the functionality of isset. Any help would be appreciated.

[PHP] multiple select list
Hello All, I have seen what I am trying to do on other web sites, but they were written in client side scripting languages. This may or may not be a limitation of server side scripting languages. What I am trying to do is dynamically generate 2 drop down list. I want the second list to contain different values based on what people choose in the first drop down list. If someone could guide me to some documentation on how to accomplish this it would be greatly appreciated.
