Email verification - at least verify its in e mail form

[jduke6]

function isValidEmail($email){

return eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $email);

}

 

How do I incorporate the code above into my code?? 

 

<?php 

error_reporting(E_ALL ^ E_NOTICE); 
?>
<?php
// make sure the form has actually been submitted . . .
if( strtolower($_SERVER['REQUEST_METHOD']) === 'post' ) { 


// 1. Create a database connection
$connection = mysql_connect("localhost", "root", "maven777");
if(!$connection){
	die("Database connection failed: " .mysql_error());
}

// 2. Select a database to use
$db_select = mysql_select_db("homesloans", $connection);
if(!$db_select){
	die("Database selection failed: " .mysql_error());
}

$radius = ($_POST['radius']);
$type = ($_POST['type']);
$price = ($_POST['price']);
$bedrooms = ($_POST['bedrooms']);
$bathrooms = ($_POST['bathrooms']);
$parking = ($_POST['parking']);
$city = ($_POST['city']); 
$details = ($_POST['details']);
$firstname = ($_POST['firstname']);
$lastname = ($_POST['lastname']);
$email = ($_POST['email']);
$phone = ($_POST['phone']);





$query="INSERT INTO leads (leadid, city, radius, type, price, bedrooms,
bathrooms, parking, details, firstname, lastname, email, phone)

VALUES('NULL', '[$city]', '[$radius]', '[$type]', '[$price]', '[$bedrooms]',
		'[$bathrooms]', '[$parking]', '[$details]', '[$firstname]', '[$lastname]', 		            '[$email]', '[$phone]')";

mysql_query($query) or die ('Error updating database');

echo "Database Successfully Updated."; // not necessarily. The only way to know for sure is to check  that mysql_affected_rows() > 0
}
?>

The absolute best email validation solution atleast in my opinion is is_email

http://code.google.com/p/isemail/

I incorporate it into all of my sites. It verifys addresses against all RFC codes

what about PHP's filter_var function? I'm sure there are issues, feel free to inform me.

function checkEmail($email) {
return filter_var($email, FILTER_VALIDATE_EMAIL);
}

if you just want to verify it's an emailaddress i would go for the native filter_var function. saves 52kb.
