    Hello everyone!

    I need some help with regular expressions. I'm using preg_match to validate name field for a form. I need to allow only alphabets and spaces. I'm unable to get it working for spaces. Please suggest me some code.

    Here is what i'm doing. if(!preg_match('[a-zA-Z\s]', $name))...

    Thanks

    Right now you're letting in just a single character, you need to wrap your expression in () and add + after the [] which means 1 or more.

    This should work: ([a-zA-Z\s]+)

    Note the space after the second Z, thats all you have to do.
    
"/^[a-zA-Z ]+$/"
    PHP:
    ..and this one indicates the first letter needs to be a Capital letter, which names should be I guess.
    
"/^[A-Z][a-zA-Z ]+$/"
    PHP:
