passing data in url, what happens if no data is passed

[deadlyhifi]

I am working in php with MySQL.

Some of the pages in my site require some data to be passed in the url. In most cases it is 'data_region'. If this isn't passed in the url I get an 'undefined index' error. Is there a way to say:

if 'data_region' exists use the information that it passes,
else use '?data_region=ALL'

At the moment I am just using a web forwarder on the index page to forward to the main.php with the correct data_region instead of having main.php as the index. This is OK but it sometimes takes a while, especially on slower connections.

Any help appreciated.

My code:

Yes, there is. Dreamweaver should take care of this for you, but the
recordset code ignores the default value.

Change the following section from this:

> $region = "ALL";
> if (isset($_GET['data_region'])) {
> $colname_rs_video = (get_magic_quotes_gpc()) ? $_GET['data_region'] :
> addslashes($_GET['data_region']);
> }

To this:

$region = "ALL";
if (isset($_GET['data_region'])) {
$colname_rs_video = (get_magic_quotes_gpc()) ? $_GET['data_region']
: addslashes($_GET['data_region']);
}
else {
$colname_rs_video = "ALL";
}

Thanks for your reply.

I can see what you're trying to do here but it isn't working because it is still looking for '?data_region' in the URL. I need it to apply 'data_region=ALL' when 'data_region' is not mentioned in the URL.

In that case, put this at the top of your page:

if (!isset($_GET['data_region']) $_GET['data_region'] = 'ALL';

you Monsieur Powers deserve an award.

don't forget the extra ')' though...

if (!isset($_GET['data_region'])) $_GET['data_region'] = 'all';
