email validator

[fogofogo1]

Hello all!

Below I have a simple script that takes an email address from a user and stores it in a database. I have a regex validator in there, but it always returns false. any ideas why?

here is the code..

<?php

 # this function will validate the email
function checkEmail($EMAIL) 
{
   if(eregi("^[a-zA-Z0-9_]+@[a-zA-Z0-9\-]+\.[a-zA-Z0-9\-\.]+$]", $EMAIL)) 
   {
	  return false;
   }
}

# this is processed when the form is submitted 
# back on to this page (POST METHOD) 
if ($_SERVER['REQUEST_METHOD'] == "POST")  
	{ 	
	# check the email is valid
	if(checkEmail($EMAIL) == FALSE) 
	{
  	 	echo "E-mail entered is not valid.";
	} 

	else 
	{
		# escape data and set variables 
		$EMAIL = addslashes($_POST["EMAIL"]); 

		# setup SQL statement 
		$sql  = " INSERT INTO elcartonazoemail "; 
		$sql .= " (email) VALUES "; 
		$sql .= " ('$EMAIL') "; 

		#execute SQL statement 
		$result = mysql_query($sql, $cid); 

		# check for error 
		if (mysql_error()) { print "Database ERROR: " . mysql_error(); } 

		print "<h3>email added</h3>"; 
	}	 	   
}
?> 

<form name="fa" action="index2.php" method="POST">      
<table>                                                                                                         
<tr><td><b>EMAIL: </b> </td><td><input type="text" name="EMAIL" size=30></td></tr>  
<tr><th colspan=2><p><input type="submit" value="Add Record"></p></th></tr>  
</table>

You need to explicitly return true at the end of the function.

PS: A more thorough function that will return more accurate results can be found here: http://www.iamcal.com/publish/articles/php/parsing_email/
