Mandatory Fields

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

I currently have the following for some mandatory fields:

$Mandatory_Fields="*Customer Name*Customer Email*Phone Number*Payment 
+Method*BillingAddressLine1*BillingCity*BillingPostCode*CardStartDate*
+CardIssueNo*CardSecurityCode";
[download]

Idealy I would like to make the CardStartDate, CardIssueNo and CardSecurityCode only mandatory if credit card as a payment method is selected. Is there anything like an immediate if I could place in there to only make these mandatory if a radio button is true? I hope I have explained this clearly. Thanks as always. Simon

Make it a bit more readable while you're at it. `$Mandatory_Fields= '' . join( '', 'Customer Name', 'Customer Email', 'Phone Number', 'Payment Method', 'BillingAddressLine1', 'BillingCity', 'BillingPostCode', param( 'Payment Method' ) eq 'Credit Card' ? qw( CardStartDate CardIssueNo CardSecurityCode ) : () );` [download] Update: I see that Anonymous wants a '*' before each entry including the first one, not just as a delimeter.

Hi, I have just tried: `$Mandatory_Fields= '' . join( '', 'Customer Name', 'Customer Email', 'Phone Number', 'Payment Method', 'BillingAddressLine1', 'BillingCity', 'BillingPostCode', param( 'payMethods' ) eq 'Credit Card' ? qw( CardStartDate CardIssueNo CardSecurityCode ) : () );` [download] But I am getting an internal server error when trying it out. Any ideas please?	[reply] [d/l]

Try running: perl -c scriptname Internal server errors are usually the result of your code not compiling. If that is the case, running perl -c will give you a more helpful error message.	[reply]

using CGI.pm you could. `if ( $cgi->param("radiobutton") eq "true" ) { $Mandatory_Fields = "this and that and that..."; }else { $Mandatory_Fields = "this and that..."; }` [download] -silent11	[reply] [d/l]
