PHP MD5 Create User Form -

-

i have used tutorial here: http://www.phpeasystep.com/phptu/26.html create login form website. have set upassword field in database md5 , of passwords in database encrypted md5.

the login works perfectly, confused creating registration form.

the form requests user input desired password. confused how take password user inputs, converting md5 , inputting md5 password upassword field in user table.

below code have processresgistration.php file:

/* database connection info*/ mysql_select_db("dbname", $con);  $encryptedpassword = md5($_post['upassword']);  md5($upassword);  $sql="insert users (uname, upassword, usurname, ufirstname) values ('$_post[uname]','$encryptedpassword','$_post[usurname]','$_post[ufirstname]'";  if (!mysql_query($sql,$con))   {   die('error: ' . mysql_error());   } echo "account created.  can login";  mysql_close($con) ?>

the code above supposed to:

  • create variable named encryptedpassword
  • use upassword encryptedpassword
  • convert encrypted password md5
  • input md5 password users table upassword

i'm sure i've not used correct variable somewhere, or have done simple error syntax; comments/help appreciated!

thanks, chris m

you code require validation & escaping, more :

<?php  /* database connection info */ mysql_select_db("dbname", $con);  if ($_request['method'] == 'post') {     $uname = filter_input(input_post, 'uname');     $upassword = filter_input(input_post, 'upassword');     $usurname = filter_input(input_post, 'usurname');     $ufirstname = filter_input(input_post, 'ufirstname');      // validation here ...      // if ok, crypte password     $hashedpassword = md5($upassword);      // , store      $sql = sprintf(         'insert users (uname, hashedpassword, usurname, ufirstname)          values (%s, %s, %s, %s);',             mysql_real_escape_string($uname, $con),             mysql_real_escape_string($hashedpassword, $con),             mysql_real_escape_string($usurname, $con),             mysql_real_escape_string($ufirstname, $con)     );      if (!mysql_query($sql,$con)) {         die('error: ' . mysql_error());     }      mysql_close($con);     echo "account created.  can login"; }  ?>

now login

<?php  if ($_request['method'] == 'post') {     $uname = filter_input(input_post, 'uname');     $upassword = filter_input(input_post, 'upassword');     $hashedpassword = md5($upassword);      $sql = sprintf(         'select * users uname = "%s" , hashedpassword = "%s" limit 1',             mysql_real_escape_string($uname, $con),             mysql_real_escape_string($hashedpassword, $con),         );      // etc etc ... } ?>
