Validate field input is string laravel

Question

In the documentation I saw this

string:value

The field under validation must be a string type.

But as I understand (from the scarce explanation + the example given) I must validate with a certain string value. But what I want is to validate simply that the input value contains just letters from the alphabet.

Apparently

'name'  => 'required|string'

won't cut it, because it has to be string:SomeValue

So, what is the correct way, to set a validation rule In the model class that validates against string?

@Dagon, what do you mean by context? A certain value to validate with, or what? — Milkncookiez

I think what you're looking for is the 'alpha' validation rule Laravel provides. This will ensure the value you are validating contains only alphabetic characters. Docs: http://laravel.com/docs/4.2/validation#available-validation-rules

You can use the regex validator for this:

'name'  => ['required', 'regex:/^([a-zA-Z]+)(\s[a-zA-Z]+)*$/']

([a-zA-Z]+): This means that the input must begin with one or more letters.

(\s[a-zA-Z]+)*: This means that after the first word (name) you can add one space with another word (name) & it can be done 0 or more times.

If you want to force the user to input his first name(s) + last name(s) you could change the '*' character to a '+' character.

This might be a late answer but it still might help someone.

Also, you can use

required|min:3|max:100|regex:/^[\p{L}\p{M}\s.\-]+$/u

This regular expression pattern is used for validating a string containing Unicode alphabetic characters, including letters, marks, and spaces.
The pattern starts with ^ which means the start of the string, followed by [\p{L}\p{M}\s.-]+, which is the character class that matches one or more occurrences of Unicode alphabetic characters (\p{L}), marks (\p{M}), spaces (\s), hyphen (-), and dot (.) characters.
The + sign after the character class specifies that it should match at least one occurrence of the characters within the character class.
