Data::Validate::Email Description

Data::Validate::Email contains common email validation methods. Data::Validate::Email contains common email validation methods.SYNOPSIS use Data::Validate::Email qw(is_email is_email_rfc822); if(is_email($suspect)){ print "Looks like an email addressn"; } elsif(is_email_rfc822($suspect)){ print "Doesn't much look like an email address, but passes rfc822n"; } else { print "Not an email addressn"; } # or as an object my $v = Data::Validate::Email->new(); die "not an email" unless ($v->is_email('foo'));This module collects common email validation routines to make input validation, and untainting easier and more readable.All functions return an untainted value if the test passes, and undef if it fails. This means that you should always check for a defined status explicitly. Don't assume the return will be true. (e.g. is_username('0'))The value to test is always the first (and often only) argument.FUNCTIONSnew - constructor for OO usage new();DescriptionReturns a Data::Validator::Email object. This lets you access all the validator function calls as methods without importing them into your namespace or using the clumsy Data::Validate::Email::function_name() format.ArgumentsAn optional hash reference is retained and passed on to other function calls in the Data::Validate module series. This module does not utilize the extra data, but some child calls do. See Data::Validate::Domain for an example.ReturnsReturns a Data::Validate::Email objectis_email - is the value a well-formed email address? is_email($value);DescriptionReturns the untainted address if the test value appears to be a well-formed email address. This method tries to match real-world addresses, rather than trying to support everything that rfc822 allows. (see is_email_rfc822 if you want the more permissive behavior.)In short, it pretty much looks for something@something.tld. It does not understand real names ("bob smith" ), or other comments. It will not accept partially-qualified addresses ('bob', or 'bob@machine')Arguments$valueThe potential address to test.ReturnsReturns the untainted address on success, undef on failure.Notes, Exceptions, & BugsThis function does not make any attempt to check whether an address is genuinely deliverable. It only looks to see that the format is email-like.The function accepts an optional hash reference as a second argument to change the validation behavior. It is passed on unchanged to Neil Neely's Data::Validate::Domain::is_domain() function. See that module's documentation for legal values.is_email_rfc822 - does the value look like an RFC 822 address? is_email_rfc822($value);DescriptionReturns the untainted address if the test value appears to be a well-formed email address according to RFC822. Note that the standard allows for a wide variety of address formats, including ones with real names and comments.In most cases you probably want to use is_email() instead. This one will accept things that you probably aren't expecting ('foo@bar', for example.)Arguments$valueThe potential address to test.ReturnsReturns the untainted address on success, undef on failure.Notes, Exceptions, & BugsThis check uses Casey West's Email::Address module to do its validation.The function does not make any attempt to check whether an address is genuinely deliverable. It only looks to see that the format is email-like.is_domain - does the value look like a domain name? is_domain($value);DescriptionReturns the untainted domain if the test value appears to be a well-formed domain name. This test uses the same logic as is_email(), rather than the somewhat more permissive pattern specified by RFC822.Arguments$valueThe potential domain to test.ReturnsReturns the untainted domain on success, undef on failure.Notes, Exceptions, & BugsThe function does not make any attempt to check whether a domain is actually exists. It only looks to see that the format is appropriate.As of version 0.03, this is a direct pass-through to Neil Neely's Data::Validate::Domain::is_domain() function.The function accepts an optional hash reference as a second argument to change the validation behavior. It is passed on unchanged to Neil Neely's Data::Validate::Domain::is_domain() function. See that module's documentation for legal values. Requirements: · Perl
