Allow only letters; no punctuation no numbers

Hey guys can you help me with this. I've got this '/[^A-Za-z]/' but cannot figure out the punctuations part.

Gracious!

#^[^a-z]+$#i

Your code was correct, you just need ^ and $. So it means all character from the beginning to the end doesn't allow outside alphabet. Negative match is preferred than positive match here.

you can also use the shorthand \w for a "word character" (alphanumeric plus _). Of course some regex engines may differ on support for this, but if it's PCRE it should work. See here (under heading "escape sequences").

The regular expression you are using doesn't allow letters; it's the opposite of what you are reported in the title.

/[a-z]/i is enough, if you want to accept only letters. If you want to allow letters like à, è, or ç, then you should expand the regular expression; /[\p{L}]/ui should work with all the Unicode letters.

Inside of a character class, the ^ means not. So you're looking for not a letter. You want something like

[A-Za-z]+

/[^A-Za-z]*/ will match everything except letters. You shouldn't need to specify numbers or punctuation.
