Activation Code - PHP (:

[Stotty]

Ive made a register page and it emails a activation code

 

$activ_code = rand(1000,9999);
$server = $_SERVER['HTTP_HOST'];
$host = ereg_replace('www.','',$server);
mysql_query("INSERT INTO users
              (`user_email`,`user_pwd`,`country`,`joined`,`activation_code`,`full_name`)
			  VALUES
			  ('$_POST[email]','$md5pass','$_POST[country]',now(),'$activ_code','$_POST[full_name]')") or die(mysql_error());

$message = 
"Thank you for registering an account with $server. Here are the login details...\n\n
User Email: $_POST[email] \n
Password: $_POST[pass2] \n
Activation Code: $activ_code \n
____________________________________________
*** ACTIVATION LINK ***** \n
Activation Link: http://$server/activate.php?usr=$_POST[email]&code=$activ_code \n\n
_____________________________________________
Thank you. This is an automated response. PLEASE DO NOT REPLY.

ATM : the code is 4 letters so anything from 0000 to - 9999 random

 

So output is Your activation code is : 8989 i want it to look more pro and send out

 

Your activation code is 1089-8778-9090-8787

 

 

Thanks

In advanced

for($i=0;$i < 4; $i++)
{
   $activ_code.= rand(1000,9999).($i < 4 ? "-" : '");
}

 

That will loop through four times, generate a random number (*make sure you look up how to really make this more random*) and then add a "-" between the number so long as we're not over 4 loops

[Ken2k7]

$i = 0;
$activ_code = '';
while (++$i < 5) $activ_code .= rand(1000, 9999) . '-';
$activ_code = rtrim($activ_code, '-');

 

OR

 

$i = 0;
$activ_code = array();
while (++$i < 5) $activ_code[] = rand(1000, 9999);
$activ_code = implode('-', $activ_code);

Thanks KEV

 

after using that code in the email it send the write code 7787-8880-9990-9989

 

but in the database its still imputting 2456 a 4 numbered one

 

How can i fix this

 

$i = 0;
$activ_code = array();
while (++$i < 5) $activ_code[] = rand(1000, 9999);
$activ_code = implode('-', $activ_code);
$server = $_SERVER['HTTP_HOST'];
$host = ereg_replace('www.','',$server);
mysql_query("INSERT INTO users
              (`user_email`,`user_pwd`,`country`,`joined`,`activation_code`,`full_name`)
			  VALUES
			  ('$_POST[email]','$md5pass','$_POST[country]',now(),'$activ_code','$_POST[full_name]')") or die(mysql_error());

 

 

Imputting into the database code is

"INSERT INTO users
              (`user_email`,`user_pwd`,`country`,`joined`,`activation_code`,`full_name`)
			  VALUES
			  ('$_POST[email]','$md5pass','$_POST[country]',now(),'$activ_code','$_POST[full_name]')") or die(mysql_error());

 

 

Thanks
