You should be able to check it using a regular expression. Should be plenty of examples on Google...

Thanks

I've used many regex's over the years -- some strict some not; but my current method for validating email with PHP is using the PHP's pre-baked filter_var()

PHP Code:

  //best way is with php5 filters: 
if(!filter_var(, FILTER_VALIDATE_EMAIL)){
    return false;
}

Thanks

You could use this,

//email validations
if(!$this->validate_email($_POST['email']))
{
$this->add_error("Please provide a valid email address");
$ret = false;
}

With this function
function validate_email($email)
{
return eregi("^[_\.0-9a-zA-Z-]+@([0-9a-zA-Z][0-9a-zA-Z-]+\.)+[a-zA-Z]{2,6}$", $email);
}

Hope that helps,

Shawn

use this,

if(!empty($_POST['email'])) {
if(!preg_match("/^[_\.0-9a-zA-Z-]+@([0-9a-zA-Z][0-9a-zA-Z-]+\.)+[a-zA-Z]{2,6}$/i", $_POST['email'])){
$errors = "Please enter a valid email address.";
} else { $email = mysql_real_escape_string(trim($_POST['email'])); }
} else { $errors[] = "You forgot to enter email address."; }

Hi,

First make sure your input type is email.

<input type="email" size="30" value="" />

Then for 2nd layer validation, just use the code provided by dwoods.

Use PHP built in functions

if(filter_var($mail, FILTER_VALIDATE_EMAIL))
{
echo "Mail is valid!";
}
