What is the regex for : Allow only letters and spaces but not start with space?

Question

I'm writing a program that let people enter their infomation (name, age....) .For the name input I don't want them to left blank and allow only letters and spaces but not start with space. What is the appropriate regex? I tried with : ^[a-zA-Z\\s]*$ but it didn't work. Thanks!

Answer 1

^([a-zA-Z]+\s*)+$ should do the job

Answer 2

Try this: ^[a-zA-Z][a-zA-Z\s]*$

Answer 3

You should specify the first character separately:

^[a-zA-z][a-zA-Z\\s]*$
