Sending login information in an e-mail if user forgets, HELP!

[SauloA]

I'm trying to create a form that will that will send a user their password through an email.  The user is supposed to put their username in the text box and than get an email with their login information.

 

Here's my code.  The problem seems to be this code.  I'd appreciate the help.

 

mysql_select_db($database_connBlog, $connBlog);
$sql="SELECT user_pass, user_email FROM user_tbl WHERE user_sname='".$user_sname."'"; 
$r = mysql_query($sql, $connBlog); 
if(!$r) { 
  $err=mysql_error(); 
  print $err; 
  exit(); 
} 
if(mysql_affected_rows()==0){ 
  print "no such login in the system. please try again."; 
  exit(); 
} 
else { 
  $row=mysql_fetch_array($r); 
  $password=$row["user_pass"]; 
  $email=$row["user_email"]; 

  $subject="your password"; 
  $header="from:[email protected]"; 
  $content="your password is ".$password; 
  mail($email, $subject, $row, $header); 

  print "An email containing the password has been sent to you"; 
}

Here's the form where the usename is inputted.

<form name="forgot" method="post" action="forgot.php">
  <input name="sname" type="text" value="user_sname" size="20"/><br />
  <input type="submit" name="submit" value="submit"/>
  <input type="reset" name="reset" value="reset"/>
</form>

 

If this isn't a good way of sending login information.  Can someone send me in the right dircetion?

What exactly is the problem? You are yet to ask a question.

I don't know what the problem is.  I'm assuming that there's somthing wrong with my code.  Maybe somebody can tell me what's missing or how to fix it.

What is the symptoms of your problem? What isn't happening that you expect to happen?

[SauloA]

The part of my code that says:

 

if(mysql_affected_rows()==0){

  print "no such login in the system. please try again.";

  exit();

 

is working is displaying "no such login in the system. please try again." as it should display if there is an error.

 

I don't know what the error is though.

Well for one there is no function called that...

mysql_affected_rows() only works with queries which actually alter records not SELECT statements. Your code might look more like....

 

<?php
  mysql_select_db($database_connBlog, $connBlog);
  $sql="SELECT user_pass, user_email FROM user_tbl WHERE user_sname='".$user_sname."'"; 
  if (!$r = mysql_query($sql, $connBlog)) {  
    $err=mysql_error(); 
    print $err; 
    exit(); 
  }
  if (!mysql_num_rows()){ 
    print "no such login in the system. please try again."; 
    exit(); 
  } 
  $row=mysql_fetch_array($r); 
  $password=$row["user_pass"]; 
  $email=$row["user_email"]; 

  $subject="your password"; 
  $header="from:[email protected]"; 
  $content="your password is ".$password; 
  if (mail($email, $subject, $row, $header)) { 
    print "An email containing the password has been sent to you"; 
  }
?>

Um... Yes there is.

Weird...when I looked it up in the manual to check the arguments, it redirected me to mysqli_affected_rows - over and over again.

Now it's not doing it...wtf was I doing?

[SauloA]

There's still an error with:

 

  if (!mysql_num_rows()){

    print "no such login in the system. please try again.";

    exit();

  }

 

in your code thorpe.

Instead of trying to get this code to work, can somebody tell me or redirect me somewhere that shows how send a user their password through an email if the user forgets their login information.
