Regular Expressions for Custom Field Validation in RT 3.6.0

Hi Everyone,

Once I was told where Custom Field Validation is maintained in RT 3.6.0,
I thought I make this small contribution to RT 3.6.0. The following code
snippet contains several useful regexp validations. Two of these are
provided with RT 3.6.0 (Mandatory, Digits), the new additions are as
follows:

  1. DateYYYYMMDD - Date in YYYY-MM-DD or YYYY/MM/DD format
  2. DateMMDDYYYY - Date in MM-DD-YYYY or MM/DD/YYYY format
  3. DateDDMMYYYY - Date in DD-MM-YYYY or DD/MM/YYYY format
  4. Float - Floating Point Numbers
  5. Email - Email address format
  6. IPAddress - IP Address format
  7. USZipCode5 - US 5 digit Zip Code
  8. UZZipCode9 - US 9 digit Zip Code
  9. USZipCode5or9 - US Zip Code (either 5 digit or 9 digit)
  10. USTelephone - US Telephone Numbers
  11. RowRackHeight - Something used by us locally for locating
    equipment in out data center; Row #, Rack #, and Unit Height # in Rack.

I hope you find this information useful. Also, if folks have additional
regular expressions they should contribute them to this forum so they
can be shared with everybody.

Take care!

The following module contains the Custom Field Validation definitions
for RT 3.6.0:

/opt/rt3/share/html/Admin/CustomFields/Modify.html

The following code begins at line 82; I removed the regexp for “Years”
and added new code beginning at line 89:

<& /Widgets/ComboBox,

Name    => 'Pattern',

Default => $CustomFieldObj->Pattern,

Size    => 50,

Values  => [

    '(?#Mandatory).',

    '(?#Digits)^[\d.]+$',

‘(?#Float)^(+|-)?([0-9]+.?[0-9]*|.[0-9]+)(eE?[0-9]+)?’,

    '(?#DateYYYYMMDD)^(19|20)\d\d([-

/.])(0[1-9]|1[012])\2(0[1-9]|[12][0-9]|3[01])$',

    '(?#DateMMDDYYYY)^(0[1-9]|1[012])[-

/.](0[1-9]|[12][0-9]|3[01])- /.\d\d’,

    '(?#DateDDMMYYYY)^(0[1-9]|[12][0-9]|3[01])[-

/.](0[1-9]|1[012])- /.\d\d’,

‘(?#Email)[1][\w.-][a-zA-Z0-9]@[a-zA-Z0-9][\w.-][a-zA-Z0-9].[
a-zA-Z][a-zA-Z.]*[a-zA-Z]$’,

‘(?#IPAddress)^((25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9][0-9]|[0-9]).){3}
(25[0-5]|2[0-4][0-9]|1[0-9][0-9]|[1-9][0-9]|[0-9])$’,

    '(?#USZipCode5)^\d{5}$',

    '(?#USZipCode9)^\d{5}-\d{4}$',

    '(?#USZipCode5or9)^\d{5}(-?\d{4})?$',

‘(?#USTelephone)^1?\s*-?\s*(\d{3}|(\s*\d{3}\s*))\s*-?\s*\d{3}\s*-?\s*
d{4}$’,

    '(?#RowRackHeight)^\d{2}-\d{2}-\d{2}$',

    '',

],

Nick,

I submitted a patch to Jesse that implements a callback
so that new validations can be easily added. Hopefully the
patch will make it into 3.6.1.

Also, for every validation it would be useful to have
another validation that makes it possible to insert
no data.

For example:

(?#Date)^\d\d\d\d-\d\d-\d\d$
(?#Optional Date)^(\d\d\d\d-\d\d-\d\d)?$

The first requires a date. The second allows a blank
CF, but a date is entered it has to match the format.
