Email field validation

Please let me know the email field validation
Regards,
Pallavi

I made an awesomely good email verification string:
'^[[:alnum:]][[:alnum:]_\-\.]*@([[:alnum:]]([[:alnum:]\-]*[[:alnum:]])?\.)+[[:alpha:]]+$'Try to break it for me :)
-UPDATE 1-
'^[[:alnum:]]([[:alnum:]_\-\.]*[[:alnum:]])?@([[:alnum:]]([[:alnum:]\-]*[[:alnum:]])?\.)+[[:alpha:]]+$'Forgot the last character of the local part has to be alnum :)
Argh, hyphens still break it in the local part.
-UPDATE 2-
'^[[:alnum:]]([-[:alnum:]_\.]*[[:alnum:]])?@([[:alnum:]]([-[:alnum:]]*[[:alnum:]])?\.)+[[:alpha:]]+$'Hah, apparently hyphens can't be escaped from...
You have to put them at the start or end of the list.

Email field validation function

HI,
I came across this regular expression which i am using for email validation :
var filter=/^(\w+(?:\.\w+)*)@((?:\w+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$/iCould you please explain the reg expression.Also how can i include
"-" (hyphen) and underscore to this reg expression?
Thanks a lot!

Why not use the jakarta EmailValidator?
org.apache.commons.validator.EmailValidator
then you can say things like
public boolean vaildEmailAddress(String sEmail){
EmailValidator emailValidator = EmailValidator.getInstance();
return emailValidator.isValid(sEmail);
)

Validating Emails fields in my Dialog Box

Hi all, I want to validate emails in my dialog box. My field are automatically fill by an XML and I want to validate them. I am able to validate them when the user enter a new email but if the user do not enter a new email and hit "OK", there is no validation. Any idea? Thanks!
var submitEmailTo = "[email protected]\rclient@somewherecom"
var submitEmailFrom = "[email protected]"
var patt = /^[a-zA-Z0-9_.+-]+@[a-zA-Z0-9-]+\.[a-zA-Z0-9-.]+$/g;

Actually this code is attached to a button action. When my form is opened at first, my fields are populated and all the extra information are send to custom metadata.
The opearator here, will hit a button and a big dialog box appear with all the job information. You see actually only the email cluster. The idea is to help the operator to easily build an email with copy and paste. Sometime the emails fields will be filled automatically and sometime the operator will fill them.
The reason I go through a dialog box is I don't want the client to see to much information and the email is sent by a another application.
My first idea was to put a validation script on the "OK" button but it seems not possible to "cancel" this action.

Validating Email Field

Hi
I am developing a form in which there is an email field which i have to enter in a textArea.
tell me how can i check whether the entered email id is valid or not.
Its urgent
Thanks in advance
Dhiraj

In case you are using JDK version prior to 1.4 you can use following function.
<pre>
* Validates the structure of the Email Address. This method covers most
* requirements of the RFC822 specification.
* @param strEmailAddress Email Address to be validated
* @return true if validation is successful, false otherwise
* @see RFC822
* @see * Online Email Validator
public static boolean isValidEmailAddress(String strEmailAddress)
          boolean bValid = true;
          // return false if strEmailAddress is either null or empty
          if (isNullorEmpty(strEmailAddress)) {
               return false;
          // calculate length of the email address
          int iLength = strEmailAddress.length();
          // get the first occurrence of @ char
          int iCharAtPosition = strEmailAddress.indexOf("@");
          // validation fails if @ character is not present
if (iCharAtPosition == -1) {
     bValid = false;
          // validation fails if @ character found is in the first or last position
else if ((iCharAtPosition == 0) || (iCharAtPosition == (iLength - 1))) {
     bValid = false;
          // validation fails if more than 1 @ character are present
else if (strEmailAddress.indexOf("@", iCharAtPosition + 1) > -1) {
bValid = false;
          else {
               // traverse thru all the characters in the given email address
     for (int i = 0; i < iLength; i++) {
          // get the character at the i position
     char c = strEmailAddress.charAt(i);
     if (c == '.') {
                         // validation fails if . character found is in the first or last position
          if ((i == 0) || (i == (iLength - 1))) {
          bValid = false;
          break;
     // . character cannot come before @ character
     else if (i == (iCharAtPosition-1)) {
          bValid = false;
          break;

Update address-dependent email field on save of BP

We have a requirement to update the address-dependent email field from the address-independent email field upon saving a Business Partner.
I've been working on the 'BUPA_ADDR_UPDATE' BADi but am having no luck with it so far. I have managed to retrieve the data in the address-independent email field using the 'BUPA_CENTRAL_GET_DETAIL' Function Module but as yet have not been able to do the update of the address-dependent email field.
Can anyone offer any guidance please ?
thanks,
Malcolm.

Hi Malcolm,
Try using the BADI : ADDR_UPDATE.
Email is a part of the address management, so you would need an address badi.
BUPA_ADDR_UPDATE is a business partner badi and only has the address reference - such as address number, validity, move date, etc..it will not help in cases where you need to work with address fields such as city, country, email,etc.
Another approach :
Try writing your code in PARTNER_UPDATE badi. This is called after save of BP. So you can probably trigger another update on the BP's address from here..
Hope this helps you.
Cheers,
Rishu.

Field validation regular expression to accept only numbers

Hello.
I would like to have a field validation regular expression to accept only numbers - no characters. The list of pre-packaged regular expressions that are included with ApEx does not contain this and I am not a very good regular expression writer. Can anyone help?
Thanks!
Boris

Under the Regular Expression validation all you need to have is:
^[[:digit:]]$For the email address it just depends how detailed you want it:
^((?>[a-zA-Z\d!#$%&'*+\-/=?^_`{|}~]+\x20*|"((?=[\x01-\x7f])[^"\\]|\\[\x01-\x7f])*"\x20*)*(?<angle><))?((?!\.)(?>\.?[a-zA-Z\d!#$%&'*+\-/=?^_`{|}~]+)+|"((?=[\x01-\x7f])[^"\\]|\\[\x01-\x7f])*")@(((?!-)[a-zA-Z\d\-]+(?<!-)\.)+[a-zA-Z]{2,}|\[(((?(?<!\[)\.)(25[0-5]|2[0-4]\d|[01]?\d?\d)){4}|[a-zA-Z\d\-]*[a-zA-Z\d]:((?=[\x01-\x7f])[^\\\[\]]|\\[\x01-\x7f])+)\])(?(angle)>)$or...
[\w-]+@([\w-]+\.)+[\w-]+Hope these help

Email address validation

Hi,
We recently deployed a basic questionnaire being used by military personnel. We turned on the "Submission Receipts" option so that respondents could receive a copy of their submission. We have discovered that due to the elaborate format of some military email addresses (First.Middle.Last.role(civ, ctr, mil)@whatever.mil), the system was not allowing the results to be recorded because it deemed the email address invalid. Can someone verify whether or not this is indeed an issue in the FormsCentral processing?
Thanks!

Previously, we had the "Submissions Receipts" option turned on and used an email address field. We got reports that people with .mil email addresses were getting errors that the email address was invalid and subsequently the data did not seem to be captured. So, we turned off the option and changed the "Email" field to a text field so that it didn't perform the validation check. Since that field is now optional, it isn't a big issue but might be of some use in the future.
This morning I went to share access to the form to an employee who works for a company with a .us email address. When I typed in her email address, the interface said it was an invalid email address. I just tried again and this time it worked fine so if you fixed it, thanks for the quick turnaround.
If you require more detailed information or a link to the form, please email me directly. Thanks!

Email address validation pattern

First off, I'm using JDK 1.4.2_07. What I'm trying to do is validate email addresses with the String.matches(String pattern) function. What I'm having a problem with is coming up with the regex pattern that represents any syntactically valid email address. If someone has a regex pattern that does represent any syntactically valid email address, I would appreciate it if you posted it in a reply to this message. Thanks!

Email form validation

Having trouble with an email form validation. I have an email
field that is optional. Therefore, if the user leaves it blank, the
form should submit. However, I also want to check that if the user
did fill out the email address, it is valid. I am checking that if
it does not contain and '@', a '.' or does contain a ',' to give an
error. Whenever I submit a blank form, it keeps giving error that
the email address is not valid. Here is my code:
<cfif (Len(Trim(form.email)) IS 0)>
<cfif form.email does not contain "@" or form.email does
not contain "." or form.email contains ",">
<script language="JavaScript">
alert("Your email address is not valid. Please correct it
and resubmit the form.")
history.back()
</script>
<cfabort>
</cfif>
</cfif>
Please assist. Thanks, Lumpia.

Trying to create a Field Validation Expression and need help

I have a picklist field and another field that are in question. I want to set some sort of rule that forces the second field to be populated only If specific values are selected from the picklist field.
I was going the route of a field validation Rule, but everything i've tried so far does not produce the results i am trying to achieve.
The first type of expression i tried was:
([<plProduction_Print_Account_Category_ITAG>] <> LookupValue("OCC_CUST_LOV_ACCOUNT_1", "No Production Print") AND ([<stSIC_Code_ITAG>] IS NULL))
This is generating the field validation error message when i select any of the correct values from the picklist. the problem is still the second field, which will generate the error if a value is entered into the second field, regardless of the picklist value selected. Switching the "IS NULL" to "IS NOT NULL" only reverses the problem on the second field, causing the error to generate when the second field is updated to a NULL or blank value.
I also tried :
= 'No Production Print' AND [<stSIC_Code_ITAG>] IS NOT NULL
and got similar results.
([<plProduction_Print_Account_Category_ITAG>] = LookupValue("OCC_CUST_LOV_ACCOUNT_1", "No Production Print"))
Similar results as well.
Does this need to be an IIF statement? Do I need to make this a workflow expression instead? i could really use some help as I have tried everything i can think of and admit, i'm not the expression guru!!!. Any assistance would be appreciated.
TeknoMan

Yes we have the same request and we used the following expression. Example we have a field "Método de pago" ( [<plMtodo_de_pago_ITAG<]), it's values are "CHEQUE and DEPOSITO" if we select DEPOSITO three more fields were requiered Route, Sucursal de banco and Clabe so we have to put this validation in the four fields including Metodo de pago.
[<plMtodo_de_pago_ITAG>] <> "DEPOSITO" OR ([<Route>] IS NOT NULL AND [<nSucursal_de_banco_ITAG>] IS NOT NULL AND [<stCLABE_ITAG>] IS NOT NULL)
well in the field CLABE we put the following [<plMtodo_de_pago_ITAG>] <> "DEPOSITO" OR ([<Route>] IS NOT NULL AND [<nSucursal_de_banco_ITAG>] IS NOT NULL AND [<stCLABE_ITAG>] IS NOT NULL AND Len([<stCLABE_ITAG>])=18) this was because the len of the value must be 18 characters.
I hope this works for you

How can I do field validation on the last two characters of a text field?

I have a text field. The user is required to enter the last two characters as numbers. I want to apply validation on this field. How can i achieve the same?
EX: If the user enter ABCDE, an error messgae stating the last two digit should be numeric.
I tried using the below in the field validation which did not work.
(0+Right([<ExternalSystemId>],2)) > 0 AND (0+Right([<ExternalSystemId>],2)) < 99.
Any ideas would help?

Try this-
FindOneOf(Right([<Field1>],"2"),"abcdefghijklmnopqrstuvwxyz")=0

Mandatory field validation on Page links.

We have created a Portal application where we included different applications as taskflows. We have also created a tabbed interface which helps us to communicate from one task flow to another taskflow. When we are in one page of taskflow and try to move to another page of different taskflow using tabbed interface we receive mandatory field validation error which prevents us to move to any other page until we fill all the mandatory fields. We need to move to different page of taskflow by using the tabbed interface even without filling all the necessary mandatory fields. Can anyone help us to resolve this issue as this is very important for our project.

Field Validation on Read Only Field

I'm trying to create a pop up error box if a field contains null values. The problem is that the field I'm trying to do the validation on is a read-only field. It's the Account field on the Contact Object or Module. It won't allow me to include validation. The goal here is to have a POP UP ERROR box come up if someone does not select a value for that field. Making it required doesn't generate a popup box, it only has a small "required" text next to the field which can be easily missed by a user. Any ideas?

Hi !
I found the way to do what you wan't, but it sounds a bit strange for me...
You have to put a field validation on the Account Id field. I made some tests to know what is in the AccountId field when it's blank and i see that the value is "No Match Row Id" !!
So your validation rule must be simply
*<> "No Match Row Id"*
It worked for me, the error message appears... But I think this is something we have to report to Oracle...
Hope this will help, feel free to ask more !

How to pass smtp_addr(email field) to cremas idoc while creation of vendor?

Hi All,
i am creating the vendors by IDOC by using CREMAS basic type CREMAS05.
There is no email field in any of the idoc segments,as i need to pass the email address being mandatory,
i created the Z segment and added the email field into it and then created the z extension and added this zsegment into the extension.
Now how do i and where do i map this field so that email data is also passed while creating the vendor master.
i have debugged the cremas Function Module IDOC_INPUT_CREDITOR and the data is getting passed segment wise,and for customer segement i.e for the zsegment there is a enhancement section where i need to pass this field,but i do not know how do i map this field and with what structure.
Please let me know how do i handel this/or is there in other way to do it.
Thanks.
RJP.

Hi,
the email is part of the address data. It is therefore not belonging to the customer master data. So it is also not part of the DEBMAS idoctype.
To distribute via ALE accurate customer address data, you need to distribute ADRMAS, ADR2MAS, ADR3MAS idoctypes too.
