Mail Sending Problem

[clarnp49]

This is a serious problem for me. I am using some code from a script I found and like because it's complete but I am having one problem with it and it's easier to ask her because then I get an explanation of whats wrong.
The problem is it won't send the email. It fails and throws the error message of failed to send.
It used to work and now it does not, the Webhost says they did some upgrades to PHP Version 5 but I am using Version 4 with this script.

Below is the code for the forgot password, the problem is because the password is MD5 I can't it again, and if I can't send an email then I won't know what the password is. I have resorted to posting the information on fail just so the password can be retrieved, but that's insecure.

function Forgot_pwd_form(){
global $error_msg;

echo "<center><font class=\"title\">"._SEND_NEW_PASSWORD."</font>
<form method='POST' action='users.php'>
<table border='0' cellpadding='4'>
        <tr>
                <td bgcolor='#E2E2E2'>"._USERNAME." :</td>
                <td bgcolor='#E2E2E2'><input type='text' name='username' size='11'></td>
        </tr>
        <tr>
                <td bgcolor='#E2E2E2'>"._EMAIL." :</td>
                <td bgcolor='#E2E2E2'><input type='text' name='email' size='11'></td>
        </tr>
        <tr>
                <td>&nbsp;</td>
                    <td>
                    <input type='hidden' name='maa' value='do_Forgot_pwd'>
                    <input type='submit' value='"._SEND_PASSWORD."'></p>
                </td>
        </tr>
</table><center>$error_msg</center>
</form>";
}

function Forgot_pwd(){
         global $user, $prefix, $db;

         
         Forgot_pwd_form();
         
}

         $result = $db->sql_query("SELECT * FROM ".$prefix."_users WHERE username='$username' AND email='$email'");
         $check = $db->sql_numrows($result);
         if($check == 1){

         function new_pwd() {
                  $chars = "abchefghjkmnpqrstuvwxyz0123456789";
                  srand((double)microtime()*1000000);
                  $i = 0;
                  while ($i <= 7) {
                            $num = rand() % 33;
                            $tmp = substr($chars, $num, 1);
                            $pwd = $pwd . $tmp;
                            $i++;
                  }
                  return $pwd;
         }
         $new_pwd = new_pwd();

         $sql = $db->sql_query("UPDATE ".$prefix."_users SET password='$md5_password' WHERE email='$email'");

         $eol ="\r\n";

         }

         //print success message and redirect browser
         msg_redirect(""._NEW_PWD_SENT_TO_YOUR_EMAIL."","users.php","10");

         //this else for :  if($check == 1){
         }else{
                
                Forgot_pwd_form();
                echo "<center><font class=\"error\">"._WRONG_USEREMAIL."</font></center><br>";
                
         }
} 

If there is a better way of doing this please advise as I would like to understand HTML email as I am working on a newsletter script that uses this same structure.

If its MD5 you will have to use a reset password script. More work but better security when using MD5.

Have you tried just a blank php script with only the mail function in it to test if mail() is working properly on your server?

<?php

mail('your@email.com', 'My test subject', 'My Test Email');

?>

The code above should help you. If that fails you need to contact your host to find out why you cant send emails anymore. Chances are they upgraded a few other things not just php.
