Look ahead

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I know that this functionality exists...japhy told me a while back on perlguru and I lost it in the code that I was working on. Now that perlguru is down I can't look it back up.

This is what I am trying to do:

# connect to the specified driver via DBI
$dbh = DBI->connect("dbi:$input->param('driver')(RaiseError=>1):");
[download]

...but the '$input->param('driver')' can't be called like this; I get: Can't connect(dbi:CGI=HASH(0x16ec2e8)->param('driver')(RaiseError=>1):), no database driver specified...

Anyone know what that code is to do a look ahead?

TIA

PS: A perlmonks user setting question: Is there a 'email notify' option available for getting a message when a response is given? I can't find the setting anywhere.

Try executing your statement in an `eval()` block. Tip: You may want to avoid putting your email address in a node. Sooner or later it will be harvested and increase your amount of spam.

No email, but you are a frequent visitor to the Monastery, right?	[reply] [d/l]
