I have an input that can have only 2 values apple or banana. What regular expression can I use to ensure that either of the two words was submitted?

To run a “whole words only” search using a regular expression, simply place the word between two word boundaries, as we did with ‹ \bcat\b ›. The first ‹ \b › requires the ‹ c › to occur at the very start of the string, or after a nonword character.
However, to recognize multiple words in any order using regex, I'd suggest the use of quantifier in regex: (\b(james|jack)\b. *){2,} . Unlike lookaround or mode modifier, this works in most regex flavours.
A word boundary, in most regex dialects, is a position between \w and \W (non-word char), or at the beginning or end of a string if it begins or ends (respectively) with a word character ( [0-9A-Za-z_] ).
This will do:
/^(apple|banana)$/ to exclude from captured strings (e.g. $1,$2):
(?:apple|banana) Or, if you use a standalone pattern:
apple|banana There are different regex engines but I think most of them will work with this:
apple|banana If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
