Valid Email Function

I have a function that I call to check if the email address is correct and return back an error.

the call

php Code:

Original - php Code
$vs = valid_email($email); if ($vs = false) { include '../inc/header.inc'; print "<td></td><td><br><br><center><font color=green><b>Opps is this correct email ?<$email> try again please.<br><br></center></font></b>n"; include '../inc/footer.inc'; die; }

 
$vs = valid_email($email);
if ($vs = false)
    {
    include '../inc/header.inc';
    print "<td></td><td><br><br><center><font color=green><b>Opps is this correct email ?<$email> try again please.<br><br></center></font></b>n";
    include '../inc/footer.inc';
    die;
    }

the function

php Code:

Original - php Code
function valid_email($email) { // check an email address is possibly valid if (ereg("^[a-zA-Z0-9_.-]+@[a-zA-Z0-9-]+.[a-zA-Z0-9-.]+$", $email)) return true; else return false; }

 
function valid_email($email)
{
  // check an email address is possibly valid
  if (ereg("^[a-zA-Z0-9_.-]+@[a-zA-Z0-9-]+.[a-zA-Z0-9-.]+$", $email))
    return true;
  else 
    return false;
}

I can type type anything into the field and it will accept
any suggestions.....

RE: Valid Email Function

This code will do the job.

php Code:

Original - php Code
<? function valid_email($address) { if(ereg('^[a-zA-Z0-9_]+@[a-zA-Z0-9-]+.[a-zA-Z0-9-.]+$',$address)) return true; else return false; } $result=valid_email('myname@mydomain.com'); if($result) echo "Email address is valid."; else echo "Email address is invalid."; ?>

<?
function valid_email($address)
{
    if(ereg('^[a-zA-Z0-9_]+@[a-zA-Z0-9-]+.[a-zA-Z0-9-.]+$',$address))
        return true;
    else
        return false;
}
 
$result=valid_email('myname@mydomain.com');
if($result)
    echo "Email address is valid.";
else
    echo "Email address is invalid.";
?>

RE: Valid Email Function

It seems like nothing wrong with your function to validate the email. The problem is on your calling part.

Be careful when you compare with the if condition.

the link in your code

php Code:

Original - php Code
if ($vs = false)

 
if ($vs = false)

should be,

php Code:

Original - php Code
if ($vs == false)

 
if ($vs == false)

RE: Valid Email Function

or even better, do it the right way:

php Code:

Original - php Code
if (!$vs) { // ... }

if (!$vs) {
    // ...
}
