I’d like to check if the user input is an email address in JavaScript, before sending it to a server or attempting to send an email to it, to prevent the most basic mistyping. How could I achieve this?
I’m writing a very simple mock-up to demonstrate some HTML5 form-validation. However, I noticed the email validation doesn’t check for a dot in the address, nor does it check for characters following said dot.
How can I validate the input value is a valid email address using php5. Now I am using this code
RFC822 (published in 1982) defines,
amongst other things, the format for
internet text message (email)
addresses. You can find the RFC’s by
googling – there’s many many copies of
them online. They’re a little terse
and weirdly formatted, but with a
little effort we can seewhat they’re
getting at.
After reading various posts I decided not to use REGEX to check if an email is valid and simply use PHP’s inbuilt filter_var function. It seemed to work ok, until it started telling me an email was invalid because I had a number in it.
I’m working on an email validation regex in PHP and I need to know how long the TLD could possibly be and still be valid. I did a few searches but couldn’t find much information on the topic. So how long can a TLD possibly be?
Is there any rule for having a specified amount of @ symbol in any email id.
Just come to my mind if we’re to check if an email id is valid or not using PHP.
Scenario:
I have a contact form on my web app, it gets alot of spam.
I am validating the format of email addresses loosely i.e. ^[email protected]+..+$
I am using a spam filtering service (defensio) but the spam scores returned are overlapping with valid messages. At a threshold of 0.4 some spam gets through and some customer’s questions are wrongly thrown in a log and an error displayed.
Using PHP, what are some ways to generate a random confirmation code that can be stored in a DB and be used for email confirmation? I can’t for the life of me think of a way to generate a unique number that can be generated from a user’s profile. That way I can use a function to make the number small enough to be included in the URL (see this link). Remember, the user has to click on the link to “confirm/activate” his/her account. If I can’t use numbers, I have no problems using both letters and numbers.
