![]() I expect Name and Source to be in the 0-50 character length, occasionally up to 150. I expect to query and/or sort based on Name, Source, Generated, and Written. There are several columns in this particular table in C# they are defined as such: I am reading about DataAttributes to further describe in C# what I want the database to do and my question is: what penalty will I be eating by having these nvarchar(max) strings in my table (see example below)? I am a programmer first, and a DBA second, by necessity. You typed '%length%' chars.I have some databases created using Entity Framework Code First the apps are working and in general I'm pretty happy with what Code First lets me do. $validator->setMessage('Youre string is too long. $validator = new Zend\Validator\StringLength() ![]() Using the setMessage() method you can set another message to be returned in case of the specified failure. You should always set an encoding manually. When your installation and your application are using different encodings, then $validator2->isValid("Ärger") // returns true $validator2 = new Zend\Validator\StringLength([ $validator->isValid("Ärger") // returns true $validator->isValid("Ärger") // returns false In this case you will see the below behaviour. We assume that your installation uses ISO and yourĪpplication it set to ISO. You can set an encoding at instantiation with the encoding option, or by using Than PHP itself, you should set an encoding manually. When your application is using a different encoding Even when you don't set the encodingĮxplicitly, PHP uses one. When you try to set a lower maximum value than the specified minimum value, orĪ higher minimum value as the actual maximum value, the validator will raise $validator->isValid('Testi') // returns false $validator->isValid('Test') // returns true $validator->isValid('Tes') // returns false Value: $validator = new Zend\Validator\StringLength() If you need a strict length, then set the min and max properties to the same $validator->isValid(".") // returns false Of 30 characters, but require at least three charcters: $validator = new Zend\Validator\StringLength() Sometimes you will need to set both a minimum and a maximum string length Īs an example, in a username input, you may want to limit the name to a maximum Limiting both minimum and maximum string length You can set the value after instantiation using the setMin() $validator->isValid("Testing") // returns true ![]() $validator->isValid("Test") // returns false Property using an integer value: $validator = new Zend\Validator\StringLength() To limit the minimal required string length, set the min SetMax() method getMax() retrieves the value. You can set the maximum allowed length after instantiation by using the $validator->isValid("Testing") // returns false $validator->isValid("Test") // returns true To limit the maximum allowed length of a string you need to set the max max: Sets the maximum allowed length for a string.īy default, this validator checks if a value is between min and max using aĭefault min value of 0 and default max value of NULL (meaning unlimited).Īs such, without any options, the validator only checks that the input is a.min: Sets the minimum allowed length for a string.encoding: Sets the ICONV encoding to use with the string.The following options are supported for Zend\Validator\StringLength: Integers, floats, dates or objects can not be validated with this validator. Zend\Validator\StringLength supports only the validation of strings. This validator allows you to validate if a given string is between a defined Limiting both minimum and maximum string length. ![]()
