Regex Validation

[Adnan Zamurred]

Hi there,

I've searched the wiki but couldn't find any example for regex expression. 

I need the following:

1. Regex validation for maximum of 100 words (Includes numbers and letters) 

2. Regex for email address e.g. @hotmail.co.uk

Can I get some assistance please?

Also, is there a way for a user to check how many words they have typed? I am building a form where the user types a passage of maximum 100 words, anything more than that should stop the user to type further.

For the word count you could try this:

^(?:\b\w+\b[\n\r\s]*){1,100}$

They may hit the character limit before the word limit though depending on the field used. You could add the text into the validation message "Max word limit reached" and add to the description of the field "Max 100 words"

For addresses it is simply

(.*@hotmail.com)

I just tried the above, it works for 100 words. However, it fails for any special characters such as full stops.

Is there a way to add it in?

@Adnan Zamurred try this:

^(?:\b\w+\b[\n\r\s\W]*){1,100}$

I missed the \W on the last one to account for special characters.
