Make sure that your project references system.web.mvc v3.xxxxx. Then your code should be something like this: using System.Web.Mvc; . . . . [Required(ErrorMessage = “This field is required.”)] public string NewPassword { get; set; } [Required(ErrorMessage = “This field is required.”)] [Compare(nameof(NewPassword), ErrorMessage = “Passwords don’t match.”)] public string RepeatPassword { get; set; }
In 3.5SP1 / 3.0SP2, they also added a new property to the ValidationRule base, namely, ValidatesOnTargetUpdated=”True”. This will call the validation as soon as the source object is bound, rather than only when the target control is updated. That may not be exactly what you want, but it’s not bad to see initially all the … Read more
I solved this same problem by overriding the validate_unique() method of the ModelForm: def validate_unique(self): exclude = self._get_validation_exclusions() exclude.remove(‘problem’) # allow checking against the missing attribute try: self.instance.validate_unique(exclude=exclude) except ValidationError, e: self._update_errors(e.message_dict) Now I just always make sure that the attribute not provided on the form is still available, e.g. instance=Solution(problem=some_problem) on the initializer.
According to the documentation: $validator = Validator::make($request->all(), [ ‘file’ => ‘max:500000’, ]); The value is in kilobytes, for example: max:10240 = max 10 MB. max:1 = max 1024 bytes. Note that there are efforts to change the value of 1 kilobytes from original 1024 to 1000 bytes, but major frameworks like Laravel remain using original … Read more
Here’s a free and sort of “outside the box” way to do it. Not 100% perfect, but it should reject blatantly non-existent addresses. Submit the entire address to Google’s geocoding web service. This service attempts to return the exact coordinates of the location you feed it, i.e. latitude and longitude. In my experience if the … Read more

// Function for basic field validation (present and neither empty nor only white space function IsNullOrEmptyString($str){ return ($str === null || trim($str) === ”); }
I believe there are three different cases that you have to worry about: strings (anything that requires quotes): ”” + replace(@string, ””, ”””) + ”” names (anything where quotes aren’t allowed): quotename(@string) things that cannot be quoted: this requires whitelisting Note: Everything in a string variable (char, varchar, nchar, nvarchar, etc.) that comes from user-controlled … Read more
You can use the DataAnnotations.Validator class, as described here: http://johan.driessen.se/archive/2009/11/18/testing-dataannotation-based-validation-in-asp.net-mvc.aspx But if you’re using a “buddy” class for the metadata, you need to register that fact before you validate, as described here: http://forums.silverlight.net/forums/p/149264/377212.aspx TypeDescriptor.AddProviderTransparent( new AssociatedMetadataTypeTypeDescriptionProvider(typeof(myEntity), typeof(myEntityMetadataClass)), typeof(myEntity)); List<ValidationResult> results = new List<ValidationResult>(); ValidationContext context = new ValidationContext(myEntity, null, null) bool valid = Validator.TryValidateObject(myEntity, context, … Read more
According to this: Do any browsers yet support HTML5’s checkValidity() method?, and this may not be the latest truth since HTML5 is a work in progress, the Form.checkValidity() and element.validity.valid should let you access validation information from JavaScript. Assuming that’s true, your jQuery would need to attach itself to the form submit and make use … Read more
