Valid email adresses

[wizardnet]

I'm building a script to subscribe a site membership. Frist step is request an activation code (generated casually by script and saved in a remote db) filling a form with a nickname and an email address. The activation code is sent on email provided by user.

The question is: how can I check if email address is a valid one (like [e-mail]) before calling mail() function?

thanks 😉

function verifyemail($email_address)
{
if (strlen($email_address) < 3) { return false; } // MAKE SURE EMAIL IS AT LEAST 3 CHARACTERS
if (strpos($email_address,"@") == "") { return false; } // MAKE SURE @ IS PRESENT
if (substr($email_address,0,1) == "@") { return false; } // MAKE SURE FIRST CHARACTER IS NOT @
if (substr($email_address,-1) == "@") { return false; } // MAKE SURE LAST CHARACTER IS NOT @
if (substr_count($email_address,"@") > 1) { return false; } // MAKE SURE THERE IS ONLY 1 @
return true;
}

Pop this in your include file, and reference it in your code.

$email_verified = verifyemail($email_address);

returns true of false.

Now you can do dynamic things based on simple "if" statements, code structure.

Hope this helps, and you have lots of fun.

OK I am having diffuclty uploading files from client to server

***************Here is my form

<form enctype="multipart/form-data" action="<?=$PHP_SELF?>?session_id=<?=$session_id?>&action=<?=$action?>" method="post">

<input type="hidden" name=MAX_FILE_SIZE value=100000000>
<input type="File" name="userfile" size="30" maxlength="255" accept="image/jpeg, image/pjpeg">
<input type="hidden" name="newname" size="30" maxlength="^255" value="<?echo $file_id ?>">

Here is my function

function do_upload($filename,$newname)

{
global $file;
global $tmp_upload_path;
global $new_file_name;
global $user_file;
global $new_name;

$file = basename($filename);
$tmp_upload_path = "server temp directory path";
$new_file_name = "server directoty/folder/path/newame.jpg";
if (!copy($tmp_upload_path.$file, $new_file_name)) echo "failed to copy file<br>\n";
return;
}

I have used this function for intranet applications without any problems, however now I am recieving errors

*************Error
Can't open file for reading

Maybe someone hase a better function I could try?

Please dont respond with something like READ THE MANUAL,I have done that. I would appreciate some real assistance from someone that knows something about file uplaods

Thanks in advance

Rosario,
sorry about that mistake replying to your thread

Bob,

No offense, but... c'mon... checking every violation with an if.. then.. is not wise -> that's why php has regexp...

Here's one for you,

function check_email($email)
{
if(!eregi("^{[a-z0-9-]+(.[a-z0-9-]+)@[a-z0-9-]+(.[a-z0-9-]+)(.[a-z]{2,4})$",} $email))
return -1;
else
return 1;
}

Merry Christmas,

Di
