making blog interface with registration and junk

[boxxertrumps]

Im creating a module akin to blogger.com and i have run into a snag...
im using this to create a user...

$new_UN = $_POST["post_user_new"]
$new_PW = $_POST["post_pass_new"]
$new_EM = $_POST["post_mail_new"]

INSERT INTO `login` ( `user` , `password` , `email` )
VALUES ( '$new_UN', '$new_PW', '$new_EM' );

CREATE TABLE `$new_UN` (`date` INT UNSIGNED NOT NULL , `title` VARCHAR( 64 ) NOT NULL ,
`entry` TEXT NOT NULL , `autoID` INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY );

How would I have a user input his/her user name and password then have the details inserted into the table that was created along with his account?

I'm not quite sure what you are asking, so let me know if this is right. You want to insert the user info in a table that's already in the db, then (after that), you want to create a new table with the name of the new user that just registered? Is this what you are trying to accomplish?

no, i mean after that is done and the user adds an entry into his blog.
how would i have the password from the login form and the password in the database compared to each other.
then if they are the same, the entry is added, and if they are different, it displays a page that says "Incorrect password" or something.

you could connect to the database, then user the query

$userInfo = mysql_query("SELECT * FROM `users` where `username`='$username'");

then from there, use

//see if username is in the database

if (!mysql_num_rows($userInfo)) {

//display error message.

echo 'No such user!';
}

else { //if it is in the db, continue

$q = mysql_fetch_array($userInfo);

   if ($password != $q[password]) {

//if entered password not equal to pwd in db display error

         echo 'wrong password';
  }

  else { //if pwd is correct, display msg
        
         echo 'You are logged in!';
      postblog(); //use postblog function (or any other function)
  }
}

Hope this helps!

Thanks thetestingsite.
heres the new code.

// connection info
if ( $_POST["post_user"] != '') {
$user = $_POST["post_user"];
$password = $_POST["post_pass"];

$title = $_POST["post_title"];
$entry = $_POST["post_entrys"];
$date = date()

$userInfo = mysql_query("SELECT * FROM `login` where `user`='$user'");

if (!mysql_num_rows($userInfo)) {echo 'No such user!';}
else {
$q = mysql_fetch_array($userInfo);
if ($password != $q[password]) { echo 'wrong password'; }
else {echo 'Post Successful';
INSERT INTO `$user` ( `date` , `title` , `entry` ) VALUES ( '$title', '$entry', '$date' );
}
}
}
else {
?>

<form action="<?php echo $_SERVER[PHP_SELF]; ?>" method="post">
Username:<input type="text" name="post_user"><br />
Password:<input type="password" name="post_pass"><br />
Title:<input type="text" name="post_title"><br />
Entry:<textarea rows="20" colums="50" name="post_entry"></textarea><br />
<input type="submit" value="submit"> </form>

<?php }; ?>
