Helping Users Remember Their Email Addresses
Welcome to my blog, please feel free to subscribe to my RSS feed or leave a comment.
I’m a strong believer that users shouldn’t have to think in order to use my products. In fact, I proudly sport my copy of Don’t Make Me Think to just about every party I venture to, which could explain a lot about the number of parties I go to. In his book, Steve Krug writes a wonderful chapter on helping users recover from their mistake and the most common mistake users make when filling out their web form? Their email address. We can help users by validating at least half of their email address, which should cut down on the number of people that are signing up with errant domains.Let’s look at the PHP function checkdnsrr() which will check if the domain name actually exists and return a true if it does. To use the magic code we simply place the hostname we’re searching for between the brackets and it returns a True boolean if the domain is a valid domain. Remember, it’s better to advise the user that there may be a problem with their domain name and still allow them to complete the form.We may not be able to help them type in the first half of their email, but at least we can help with the domain.
