Validating that two fields match?
Hello,
Is there something out of the box that will let me validate if two
fields match in struts2? An example would be a form with email and
confirmingEmail fields.
Thanks,
James

If you can validate server-side, adding this functionality to your
validate function is about as basic as it gets. Do you require client
side validation?

Re: Validating that two fields match?
Posted by James Carr <ja...@gmail.com>.
I got it working with fieldexpression, but had to use .equals() vs. ==
Now my next question... in order to get the confirmation field to be
highlighted in red, I needed to add the same field validator for this
field as well. I need the other validation errors to display for the
confirm field (like "is required" and "must be valid") but I want to
suppress the message for "they should match" as it should just display
once. How can I do this without resorting to <s:if> ?
Thanks,
james

I have tried this and it doesn't seem to work at all. I am using
ModelDriven and the model object has a PointOfContact object with an
emailAddress and confirmingEmail attributes.
<field name="pointOfContact.emailAddress">
<field-validator type="requiredstring">

I have tried this and it doesn't seem to work at all. I am using
ModelDriven and the model object has a PointOfContact object with an
emailAddress and confirmingEmail attributes.
<field name="pointOfContact.emailAddress">
<field-validator type="requiredstring">
<param name="trim">true</param>
<message>Email Address is required.</message>
</field-validator>
<field-validator type="email">
<message>Please enter a valid email</message>
</field-validator>
<field-validator type="expression">
<param name="expression">(pointOfContact.emailAddress.equals(pointOfContact.confirmingEmail))</param>
<message>Verify that you have entered the same email
address in both fields</message>
</field-validator>
</field>
The other two validators above it work.

Check out
http://struts.apache.org/2.x/docs/expression-validator.html
If you are using annotations check out
http://struts.apache.org/2.x/docs/expressionvalidator-annotation.html
Your expression will be something like
@ExpressionValidator(expression="email.equals(confirmEmail)",? message="The email fields do not match")

Hello,
Is there something out of the box that will let me validate if two
fields match in struts2? An example would be a form with email and
confirmingEmail fields.
Thanks,

Hi,
I have created a validator called "SameValueValidator", this worked both
client-side and server side, this was for struts2.0.x so I don't know
how will work with the latest struts (and if it works with annotations).
If You are interested here it is:
SameValueValidator.java:
--------------------------
public class SameValueValidator extends FieldValidatorSupport
{
private String otherField;
@Override
public void validate(Object object) throws ValidationException
{
String fieldName = getFieldName();
String val = (String) getFieldValue(fieldName, object);
if (val == null || val.length() <= 0) {
// use a required validator for these
return;
}
String otherVal=(String) getFieldValue(otherField, object);
if(!val.equals(otherVal))
{
addFieldError(fieldName, object);
}
}
public String getOtherField()
{
return otherField;
}
public void setOtherField(String otherField)
{
this.otherField = otherField;
}
}
--------------------------
How to use it in xml:
<field name="password2">
<field-validator type="samevalue" >
<param name="otherField">login.userPasswd</param>
<message key="error.passwordmatch" />
</field-validator>
</field>
Add it as Validator is validators.xml:
<validator name="samevalue"
class="yourpackage.validators.SameValueValidator"/>
Changes required for client-side validation (javascript):
file: template\xhtml\form-close-validate.ftl:
(there are a bunch of elseifs, add this at the end):
-----------------------------------------
<#elseif validator.validatorType = "samevalue">
if (field.value != null) {
var otherField=form.elements['${validator.otherField}'];
if (field.value!=otherField.value) {
addError(field, error);
errors = true;
}
}
</#if>
-----------------------------------------
Regards,
Andras.
