Item Name Validation rule for hyphens

Question

I have been successful in creating a field validation rule where the Title should not have hyphens by using a regex validation. That is working as expected. Now, I need to validate the items while creating it like the item's Name shouldn't have hyphens in it. I have created an Item Validation rule as shown in below image.

But, the rule is not working as expected. I tried in all types of "Validation Rules" and the items still can be created with hyphens in it. Can anyone correct me if I am missing anything.

Answer 1

The issue I can see is that you are using FieldValidators under the type i.e. Sitecore.Data.Validators.FieldValidators.RegexValidator,Sitecore.Kernel

And the logic for this validator checks for the field.

 string controlValidationValue = this.ControlValidationValue;
 if (string.IsNullOrEmpty(controlValidationValue))
        return ValidatorResult.Valid;
 string parameter = this.Parameters["Pattern"];
 if (string.IsNullOrEmpty(parameter) || new Regex(parameter, RegexOptions.IgnoreCase).IsMatch(controlValidationValue))
        return ValidatorResult.Valid;
 this.Text = this.GetText("The field \"{0}\" does not match the regular expression \"{1}\".", this.GetFieldDisplayName(), parameter);
 return this.GetFailedResult(ValidatorResult.Error);

So you should create a new validator class and use it in your validation rule by passing the class and assembly name in the Type field. Here is an example of OOTB validator that is checking the encoded character.

  Item obj = this.GetItem();
  if (obj == null || !obj.Paths.IsContentItem)
    return ValidatorResult.Valid;
  string name = obj.Name;
  string displayName = obj.DisplayName;
  if (this.ContainsEncodedAndDecodedSymbols(name))
  {
    this.Text = this.GetText(Translate.Text("The item name contains both encoded characters and characters that are used to replace encoded characters when Sitecore generates an item URL."));
    return this.GetFailedResult(ValidatorResult.Error);
  }
  if (!this.ContainsEncodedAndDecodedSymbols(displayName))
    return ValidatorResult.Valid;
  this.Text = this.GetText(Translate.Text("The item display name contains both encoded characters and characters that are used to replace encoded characters when Sitecore generates an item URL."));
  return this.GetFailedResult(ValidatorResult.Error);  

So you need to use the code that is given in the RegexValidator class and pass the name of the item, not the field.

And it will solve your issue.

You can tell Sitecore how is your regex pattern through a setting.

<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">
    <sitecore>
        <settings>    
            <setting name="ItemNameValidation">
                <patch:attribute name="value">^.*$</patch:attribute>
            </setting>
        </settings>
    </sitecore>
</configuration>

Just replace the pattern ^.*$ by yours.
