email validation

[Dean Wilson]

Hi, I have this code below and I want to add in a validation command, so the user needs to fill that space in.

I don't know where to put this code in the php. Any help would be greatfull.

function check_email ($email1) {
         return 
(ereg('^[-!#$%&\'*+\\./0-9=?A-Z^_`a-z{|}~]+'.'@'.'[-!#$%&\'*+\\/0-9=?A-Z^_`a-z{|}~]+\.'.'[-!#$%&\'*+\\./0-9=?A-Z^_`a-z{|}~]+$',$email1));
} 

Insert.php file

<?php

include("config.php");
include("global.php");

mysql_connect($DBhost,$DBuser,$DBpass) or die("Unable to connect to database");
mysql_select_db ($DBname);

mysql_query ("INSERT INTO tellafriend (Name1, Email1, Date, Name2, Email2) values ('$name1', '$email1', (now()), '$name2', '$email2')");

// Start Message to friend

$message = "This message is from your friend -- $name1 at $email1
----------
$mainmsg
";

    mail($email2,"$emailsubject",
         $message, "From:$gbsitename <$adminemail>");

?>

Try the following, I think you'll find it much better

<?php

include("config.php");
include("global.php");

mysql_connect($DBhost,$DBuser,$DBpass) or die("Unable to connect to database");
mysql_select_db ($DBname);



////////////////////////////////////////////////////////////
// validate_email
//
// - Validates Email Address
//
// Usage:
// if (!validate_email($email)) { echo 'Bad'; } else { echo 'Good'; }
////////////////////////////////////////////////////////////
function validate_email($str_input){ 
   if (eregi("^([a-z]|[0-9]|\.|-|_)+@([a-z]|[0-9]|\.|-|_)+\.([a-z]){2,3}$", $str_input, $arr_vars) && 
       !eregi("(@.*@)|(\.\.)|(@\.)|(\.@)|(^\.)", $str_input, $arr_vars)){ 
      return true; 
   }
}

if (!validate_email($Email2)) {
    echo 'Bad Email Address Entered';
}
////////////////////////////////////////////////////////////

mysql_query ("INSERT INTO tellafriend (Name1, Email1, Date, Name2, Email2) values ('$name1', '$email1', (now()), '$name2', '$email2')");

// Start Message to friend

$message = "This message is from your friend -- $name1 at $email1
----------
$mainmsg";

    mail($email2,"$emailsubject",
         $message, "From:$gbsitename <$adminemail>");

?>

Well you can put that code in any file you want (as long as you include it).

The you just would issue:

if (check_email($email_address)
{
good
}
else
{
bad
}

Where $email_address is the address you want to check. You'll have to fill in the code for good and bad.

Thanks John, can you help me a little more?

I have added that code to the insert.php file but how would I go about adding $email1, $email2, $name1, $name2 to that list.

Here is the live version, http://www.boxxnet.com.au/tellafriend/submit.php
No matter what you enter it always comes up with that error. "Bad Email Address Entered"

First, I made one slight mistake with the code above. It should be:

if (!validate_email($Email2)) {
    echo 'Bad Email Address Entered';
 exit();
}

By that do you mean if you enter multiple email addresses into the "send to" field??

If not, what do you mean?

No matter what you enter it always comes up with that error. "Bad Email Address Entered" [/B]

Well, almost impossible to tell you what you did wrong, because you have not provided me/us with the code that you have...

Telling you what it wrong, without the code, is somewhat like having to guess where a single submarine in the entire Atlantic ocean

John, there is 4 feilds. $email1 $email2, $name1 and $name2 are all different feilds.

I was it so the user has to enter his email and his friends email -- Here is the full code.

       !eregi("(@.*@)|(..)|(@.)|(.@)|(^.)", $str_input, $arr_vars)){ 
      return true; 
   }
}


if (!validate_email($Email2)) {
    echo 'Bad Email Address Entered';
 exit();

    mail($email2,"$emailsubject",

Anyway, the above should work just fine
