Question

I need a regex that will check the input of a textarea form and detect whether the form contains more than 999 words. This is language independent, i.e. I am using a form plugin that accepts regexs for validation.

Answer 1

All you need is to test simple regex match against input string. Use regex pattern

(?:\b\w+(?:\W+|$)){1000}

If you need add a unicode support, use pattern

(?:\b[\w\p{L}]+(?:[^\w\p{L}]+|$)){1000}
