email-validation

I have an email input field where i check if the email is already present in my database using ajax on losing focus from that email input. I want to make sure the email entered is in the correct format before i make an ajax call. Can i do this with html5 built-in email validator or do i have to write my own validation function? Edit:I am already using the html5 email validator but it validates the email only when the form is submitted. Matt Browne In Firefox , it should check the email for validity as you're typing by default (native HTML5 behavior): http://jsfiddle.net/xs65r/ But to support

I'm using the built-in api for scripting against Google Spreadsheets to send some booking confirmations, and currently my script breaks if someone has filled in an invalid email. I'd like it to just save some data to a list of guests that haven't been notified, and then proceed with looping through the bookings. This is my current code (simplified): // The variables email, subject and msg are populated. // I've tested that using Browser.msgBox(), and the correct column values are // found and used // The script breaks here, if an incorrect email address has been filled in MailApp.sendEmail

Array ( [0] => myemail@domain.com [1] => mysecondemail@domain.com [2] => invalidEmail.com ) Notice that the third array value is invalid email format. How do I remove it by using/creating a function? I need the valid email to implode("," the valid email) before sending an email using the mail() function. <?php $len=count($array); for ($i=0;$i<$len;$i++) if (preg_match('^[a-z0-9!#$%&*+/=?^_`{|}~-]+(?:.[a-z0-9!#$%&*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?.)+(?:[a-z]{2,4}|museum|travel)$/i',$array[$i])) echo $array[$i]; ?> $valid = array_filter($emails, create_function('$s', 'return

These are few emails which are not valid. email@domain.web .email@domain.com I have checked above emails in following websites, All of those returns invalid. http://isemail.info/about http://sqa.fyicenter.com/Online_Test_Tools/Email_Address_Format_Validator.php . Yet, android.util.Patterns.EMAIL_ADDRESS pattern validates both. Is there a bug or am I missing something? Both seems to be valid email addresses email@domain.web .email@domain.com since any email address contains three components <username>@<mail-server>.<mail-servertype or server-location> Here android.util.Patterns.EMAIL_ADDRESS

In the current app I'm building I've got a textarea where a user will enter a comma-delimited list of email addresses. I'm currently splitting the list into an array and then saving one by one. But if, say, I have this input... blah@example.com, test@example, foo@example.com ... then blah@example.com will be saved, but saving test@example will fail. So I then need to remove blah@example.com from the comma-delimited string of values that I pass back to the textarea when I show the error that test@example isn't a valid email address. Is there a better way to validate these on the server side and

For many of the sites we develop, we verify the user's email address. Typically the workflow is such: User registers for site (activation email is sent with link to activate) User verifies email address (by clicking aforementioned link) User must log in to site in order to use it (assuming they weren't already logged in) Clients often complain about this process being clunky and somewhat confusing, and I agree. The proposed solution is to remove step 3 and automatically log the user in after step 2. I'm not sure if it matters (hence the question!), but I've always been wary of automatically

As many people may already be aware, correctly validating email addresses can be somewhat of a nightmare. You can search all day long for a C# regex that matches the current RFC standards, and you'll find different regex expressions that give different results. If you look at http://en.wikipedia.org/wiki/Email_address#Local_part , you'll see that a period at the beginning or end of the local part is not allowed. Two consecutive periods are also not allowed. However, the following NUnit test proves that System.Net.MailMessage allows you to instantiate a MailMessage object for some invalid email
