</head>
<body>
<h1>Login<h1>
<form action='#' method='post'>
<table cellspacing='5' align='center'>
<tr><td>User name:</td><td><input type='text' name='name'/></td></tr>
<tr><td>Password:</td><td><input type='password' name='pwd'/></td></tr>
<tr><td></td><td><input type='checkbox' name='remember' /> <span>Remember me</span></td></tr>
<tr><td></td><td> <span><a href="forgot.php">Forgot password</a></span></td></tr>
<tr><td></td><td><input type='submit' name='submit' value='Submit'/></td></tr>
</table>

</form>
<?php
session_start();
//your values are stored in cookies, then you can login without validate
if(isset($_COOKIE['name']) && isset($_COOKIE['pwd']))
{
    header('location:welcome.php');
}
// login validation in php
if(isset($_POST['submit']))
{
 mysql_connect('localhost','root','') or die(mysql_error());
 mysql_select_db('new')  or die(mysql_error());
 $name=$_POST['name'];
 $pwd=$_POST['pwd'];
 if($name!=''&&$pwd!='')
 {
   $query=mysql_query("select * from login where name='".$name."' and password='".$pwd."' ")  or die(mysql_error());
   $res=mysql_fetch_row($query);
   if($res)
   {
    if(isset($_POST['remember']))
{
  setcookie('name',$name, time() + (60*60*24*1));
  setcookie('pwd',$pwd, time() + (60*60*24*1));
}
    $_SESSION['name']=$name;
    header('location:welcome.php');
   }
   else
   {
    echo'You entered username or password is incorrect';
   }
 }
 else
 {
  echo'Enter both username and password';
 }
}
?>
</body>
</html>

<html>

 border-radius:5px;
 }

<h1>Forgot Password<h1>
<form action='#' method='post'>
<table cellspacing='5' align='center'>
<tr><td>Email id:</td><td><input type='text' name='mail'/></td></tr>
<tr><td></td><td><input type='submit' name='submit' value='Submit'/></td></tr>
</table>
</form>
<?php
if(isset($_POST['submit']))

 mysql_connect('localhost','root','') or die(mysql_error());
 mysql_select_db('new') or die(mysql_error());
 $mail=$_POST['mail'];
 $q=mysql_query("select * from login where mail='".$mail."' ") or die(mysql_error());
 $p=mysql_affected_rows();
 if($p!=0) 
 {
  $res=mysql_fetch_array($q);
  $to=$res['mail'];
  $subject='Remind password';
  $message='Your password : '.$res['password']; 
  $headers='From:guruparthiban19@gmail.com';
  $m=mail($to,$subject,$message,$headers);
  if($m)
  {
    echo'Check your inbox in mail';
  }
  else
  {
   echo'mail is not send';
  }
 }
 else
 {
  echo'You entered mail id is not present';
 }

    1. You can't send mail from local. So you can test this feature at server.

  9. Thank you so much for this my friend, just remember guys, your site must be online and hosted for the mail function to work.

    Worked like a charm for me. :)

  10. When I try this (it's hosted on my webserver) I do not get an email. The funny thing is if I set the "to" field to an email address with the same domain as the site it works, like for example if I try sending to someone@mydomain.com or someotheraddress@mydomain.com (and the "from" is coming from mydomain) it will go through. When I try sending to someone@gmail.com or someone@somewhereelse.com it does not go through.


    I get the following error: Warning: mail(): SMTP server response: 530 SMTP authentication is required. in E:\HostingSpaces\graffix\myserverpath

    It seems like it will only send emails to my domain from someone (my contact form works fine, the user is the "from" address and my email is the "to") but not when I'm trying to send someone else an email from my domain.

    Any ideas?

    1. You can send mail only from your server. Not from local system. If u want to send mail from your local system, then you need to setup SMTP port php.ini file and also you need a net connections.

    1. We can use trim() only for trim space or any values in a string. Please check your array whether it have values or not? Then pass array values into trim().

  21. how can we reset password for above code??
    can you share the link or code?

    ReplyDelete
    Replies
    1. In this tutorial, the above code snippet only send password to corresponding mail address. So the user can see his password in his inbox.

      If you want to reset password, first get password from user and then update that password to login table. The MySQL Query is:

      "update login set password='PASSWORD' where email='MAIL' and name='NAME';"
