Data::FormValidator's main aim is to make the tedious coding of input
|
|
validation expressible in a simple format and to let the programmer focus
|
|
on more interesting tasks.
|
|
|
|
When you are coding a web application one of the most tedious though
|
|
crucial tasks is to validate user's input (usually submitted by way of
|
|
an HTML form). You have to check that each required fields is present
|
|
and that some fields have valid data. (Does the phone input looks like a
|
|
phone number? Is that a plausible email address? Is the YY state
|
|
valid? etc.) For a simple form, this is not really a problem but as
|
|
forms get more complex and you code more of them this task becames
|
|
really boring and tedious.
|
|
|
|
Data::FormValidator lets you define profiles which declare the
|
|
required fields and their format. When you are ready to validate the
|
|
user's input, you tell Data::FormValidator the profile to apply to the
|
|
user data and you get the valid fields, the name of the fields which
|
|
are missing. An array is returned listing which fields are valid,
|
|
missing, invalid and unknown in this profile.
