How do you create a contact form with React? I wish it was so easy. All you can do with React is to build a contact form. As for sending emails, you’ll have to set up a backend part using some server-side languages like PHP.


Description: ----- The filter_var function, when used with FILTER_VALIDATE_EMAIL marks an email address with an = in it as invalid. According to RFCs 822, 2822 and 5322, = is a valid component to the local-part of an e-mail address.

PHP contact forms, of course, allow for different methods of sending emails. Yep, filter_validate_email is good enough. Just remember that the BEST way to validate an email is to send them an email and let them click a link to confirm, link most sites do. Also, remember that filter_var returns FALSE for invalid emails, and remember to use === for the comparison. According to this description the valid_email() function is deprecated and scheduled for removal in CodeIgniter 3.1+. The web page says that the PHP function filter_var() should be used instead. But filter_var() takes two arguments, whereas valid_email() only takes one.
