[SOLVED] Can I make a registration form in only one script page? [more details inside]

[samoi]

Hi guys, 

 

I'm just wondering if I just make a reiteration script in only one page! and no html page to redirects the form to be $_POST submitted to another page!

 

For example:

 

The form.html

<form action="register.php" method="POST">

    username : <input type="text" name="username">

                   <br />

    password : <input type="password" name="password">

                   <br />

                     <input type="submit" value="Insert into the db">
</form>

 

 

and the register.php

 

<?php
$conn = mysql_connect("localhost", "root", "pass");
$db = mysql_select_db("database_name");

$username = clean($_POST['username']);
$password = clean($_POST['password']);

if(!$username || !$password)
   {
         echo " No input inserted! ";
   }
else
   {
         $insert = "INSERT INTO users (username, password) VALUES ('$username', '$password')";

         $do_insert = mysql_query($insert);

                echo "the data has been inserted succeffully";
   }

function clean($str)
{
        return mysql_escape_string($str);
}
?>

 

 

 

 

The question is, can I make all of them in only on page? instead of doing them in two pages, and what are the positives and negatives of using this method?

 

 

Thank you in advance.

Of course you can. A simple example.

 

<?php
  if (isset($_POST['submit'])) {
    // process form
  } else {
    // display form
?>
<form action="" method="post">
  <input type="submit" name="submit">
</form>
<?php
  }
?>
