Extracting Data

[ddluc32]

I usually only do design work, but a client wanted a log in system to his website, so I decided to do it.

 

I set everything up correctly, and users can sign up, login, and log out. However, he wants to be informed when a user logs into his site.

 

So say (user x) wants logs in, my client wants to receive an email with all of (user x)'s account information. How do I pull a row from mysql based on the login information provided?

 

My database is has 7 columns: user, pass, name, address, state, phone, email

add a column with user_id:

 

alter table table_name add column user_id int AUTO_INCREMENT;

 

next when a user logs in save the information in a session:

 

<?php
// Connect to database
$user = mysql_real_escape_string($_POST['user']);
$pass = md5($_POST['pass']);
$sql = mysql_query("select * from users_table where user = '$user' and pass = '$pass'");
if(mysql_num_rows($sql) == 1){
session_start();
$row = mysql_fetch_assoc($sql);
$id = $_SESSION['user_id'] = $row['user_id'];
$name = $_SESSION['name'] = $row['name'];
$addr = $_SESSION['address'] = $row['address'];
$state = $_SESSION['state'] = $row['state'];
$phone = $_SESSION['phone'] = $row['phone'];
$email = $_SESSION['email'] = $row['email'];
$message = <<<OPT
User ID: $id
Name: $name
Address: $addr
State: $state
Phone: $phone
Email: $email
OPT;
mail("tosomeone@somesite.com", "Title", $message);
}
?>

<?php // rnlogin.php
include_once 'rnheader.php';

echo "<h3>Member Log in</h3>";
$error = $user = $pass = "";

if (isset($_POST['user']))
{
$user = sanitizeString($_POST['user']);
$pass = sanitizeString($_POST['pass']);


if ($user == "" || $pass == "")
{
	$error = "Not all fields were entered<br />";
}
else
{
	$query = "SELECT user,pass FROM rnmembers
			  WHERE user='$user' AND pass='$pass'";

	if (mysql_num_rows(queryMysql($query)) == 0)
	{
		$error = "Username/Password invalid<br />";
	}
	else
	{
                        $user = mysql_real_escape_string($_POST['user']);
		$pass = md5($_POST['pass']);
		$sql = mysql_query("select * from rnmembers where user = '$user' and pass = '$pass'");
		if(mysql_num_rows($sql) == 1){
			$row = mysql_fetch_assoc($sql);
			$id = $_SESSION['user_id'] = $row['user_id'];
			$name = $_SESSION['name'] = $row['name'];
			$addr = $_SESSION['address'] = $row['address'];
			$state = $_SESSION['state'] = $row['state'];
			$phone = $_SESSION['phone'] = $row['phone'];
			$email = $_SESSION['email'] = $row['email'];


			echo "$id <br />";
			echo "$name<br />";
			echo "$addr<br />";
			echo "$state<br />";
			echo "$phone<br />";
			echo "$email<br />";
									}
		die("You are now logged in. Please
		   <a href='home.php?view=$user'>click here</a>.");
	}
}
}




echo <<<_END
<form method='post' action='rnlogin.php'>$error
Username <input type='text' maxlength='16' name='user'value='$user' /><br />
Password <input type='password' maxlength='16' name='pass' value='$pass' /><br />
<br />
<br />
<input type='submit' value='Login' />
</form>
_END;
?>

 

Where rnheader.php includes:

 

session_start();

if (isset($_SESSION['user']))
{
$user = $_SESSION['user'];
$loggedin = TRUE;
}
else $loggedin = FALSE;

 

It doesn't come up with any errors, but it doesn't display anything (i changed it just from mailing to just displaying for now). It displays the $id, which is 1. but the other fields are blank.

 

I appreciate the help! Thanks!

why are you doing the query twice?

[ddluc32]

That was just me being sloppy, copy and pasting your code into mine.

 

Here is what  I did. Mind you, I am not even 50% sure of what I'm doing, so if it looks wrong, it probably is.

 

updated code:

 

<?php // rnlogin.php
include_once 'rnheader.php';

echo "<h3>Member Log in</h3>";
$error = $user = $pass = "";

if (isset($_POST['user']))
{
$user = sanitizeString($_POST['user']);
$pass = sanitizeString($_POST['pass']);


if ($user == "" || $pass == "")
{
	$error = "Not all fields were entered<br />";
}
else
{
     $sql = mysql_query("select * from rnmembers where user = '$user' and pass = '$pass'");

	if (mysql_num_rows(queryMysql($sql)) == 0)
	{
		$error = "Username/Password invalid<br />";
	}
	else
	{
		$user = mysql_real_escape_string($_POST['user']);
		$pass = md5($_POST['pass']);
		if(mysql_num_rows($sql) == 1){
			$row = mysql_fetch_assoc($sql);
			$id = $_SESSION['user_id'] = $row['user_id'];
			$name = $_SESSION['name'] = $row['name'];
			$addr = $_SESSION['address'] = $row['address'];
			$state = $_SESSION['state'] = $row['state'];
			$phone = $_SESSION['phone'] = $row['phone'];
			$email = $_SESSION['email'] = $row['email'];

			echo "$id <br />";
			echo "$name <br />";
			echo "$addr <br />";
			echo "$state<br />";
			echo "$phone<br />";
			echo "$email<br />";

		die("You are now logged in. Please
		   <a href='home.php?view=$user'>click here</a>.");
	}
}
}

}



echo <<<_END
<form method='post' action='rnlogin.php'>$error
Username <input type='text' maxlength='16' name='user'value='$user' /><br />
Password <input type='password' maxlength='16' name='pass' value='$pass' /><br />
<br />
<br />
<input type='submit' value='Login' />
</form>
_END;
?>

what is:

 

queryMysql()?

[ddluc32]

function queryMysql($query)
{
$result = mysql_query($query) or die(mysql_error());
return $result;
}

[The Little Guy]

remove it from the code.

[ddluc32]

Yes. Thank you so much!
