will help you I think you got enough help with the guys, If you still not sure how to code it, here you go:
Single record
code :
$query = "SELECT     products.`product_name`, product_category.`price`
          FROM       products    
          LEFT JOIN  product_category
          ON         products.product_category_id = product_category.id
          WHERE      products.id = 3";

if ($stmt = $mysqli->prepare($query)) {     
    $stmt->execute();
    $stmt->bind_result($product_name, $price);
    $row = array();
    while ($stmt->fetch()) {
        $row = array('product_name'=>$product_name, 'price'=>$price);
    }   
    $stmt->close();
}
return $row;
$query = "SELECT     products.`product_name`, product_category.`price`
          FROM       products    
          LEFT JOIN  product_category
          ON         products.product_category_id = product_category.id
          WHERE      products.id = 3";

if ($stmt = $mysqli->prepare($query)) {     
    $stmt->execute();
    $stmt->bind_result($product_name, $price);
    $rows = array();
    while ($stmt->fetch()) {
        $rows[] = array('product_name'=>$product_name, 'price'=>$price);
    }   
    $stmt->close();
}
return $rows;
$query = "SELECT     products.`product_name`, product_category.`price`
          FROM       products    
          LEFT JOIN  product_category
          ON         products.product_category_id = product_category.id
          WHERE      products.id = 3";

if ($stmt = $pdo->prepare($query)) {     
    $stmt->execute();
    $rows = $stmt->fetchAll();
}
return $rows;

I wish this help you join is a reserved word in mySQL. You will either need to enclose it in backticks:
code :
`join` 
$id = 10;
$name = "John Doe";

$query = "INSERT INTO employee(id, name) values (?, ?)";
$query->bind_param("i", $id);
$query->bind_param("s", $name);

I hope this helps you . In order to use num_rows on prepared statements you need to call store_result first.
The manual also mention the above.
code :
<?php
// Your database info
$db_host = 'localhost';
$db_user = '';
$db_pass = '';
$db_name = '';
$code = substr(str_shuffle("0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"), 0, 20);

if (!isset($_POST['email']))
{
    die('Please fill in the email field.');
}

if (!filter_var($_POST['email'], FILTER_VALIDATE_EMAIL))
{
    die('Invalid email address');
}

$con = new mysqli($db_host, $db_user, $db_pass, $db_name);
if ($con->connect_error)
{
    die('Connect Error (' . mysqli_connect_errno() . ') '. mysqli_connect_error());
}

$sql = "SELECT first, last FROM users WHERE user = ?";
if (!$result = $con->prepare($sql))
{
    die('Query failed: (' . $con->errno . ') ' . $con->error);
}

if (!$result->bind_param('s', $_POST['email']))
{
    die('Binding parameters failed: (' . $result->errno . ') ' . $result->error);
}

if (!$result->execute())
{
    die('Execute failed: (' . $result->errno . ') ' . $result->error);
}

$result->store_result();
if ($result->num_rows == 0)
{
    die('No username found...');
}

$result->bind_result($first, $last);
$result->fetch();

// After using fetch, we can print the data
echo $first, " => ", $last;

$result->close();

$update = 'UPDATE users SET reset = ? WHERE user = ?';
if (!$stmt = $con->prepare($update))
{
    die('Update query failed: (' . $con->errno . ') ' . $con->error);
}

if (!$stmt->bind_param('ss', $code, $_POST['email']))
{
    die('Update binding parameters failed: (' . $stmt->errno . ') ' . $stmt->error);
}

if (!$stmt->execute())
{
    die('Update execute failed: (' . $stmt->errno . ') ' . $stmt->error);
}

$stmt->close();
$con->close();

if (mail($_POST['email'], "Example.org Password Reset Code", "Dear $first $last,\n\n Please visit the following url to reset your password:\n http://www.example.org/reset.php?c=$code\n\nSincerely,\nSender", "From: noreply@example.org"))
{
    echo "Email sent";
}
else
{
    echo "Failed to send email";
}
mysqli-- prepare statement failing with error "no table used"

mysqli-- prepare statement failing with error "no table used"

This might help you new to writing in php, I'm using a $mysqli->prepare() function to get a statement ready for execution, but it keeps failing and I don't know why. THe error inside the $mysqli->error is "no table used," and I can't seem to find much documentation for that either... if anyone could help out, that would be hugely appreciated. Code below: , Apparently,
code :
SELECT * FROM (SELECT ? )
PREPARE myStmt 
  FROM 'SELECT * FROM (SELECT ? ) AS tmp WHERE NOT EXISTS (
    SELECT Identifier FROM eeg WHERE Identifier = ?
    ) LIMIT 1'
PREPARE myStmt FROM "select * from (select ? from eeg) tmp"; 
PREPARE myStmt FROM "select *,? from (select * from eeg) tmp"; 
PREPARE myStmt FROM "select *,? from (select 'asdf') tmp"; 
PREPARE myStmt FROM "select * from eeg where Identifier in (select ?)"; 
if ($usertest = $datasqli->prepare("INSERT INTO eeg (Identifier) 
    SELECT ? from (select 1) tmp WHERE ? NOT IN
      (SELECT Identifier FROM eeg WHERE Identifier = ?)")) {

seems to work fine Almost every thing is ok, except you can not get the results from fetch statement as you do.
All depends on how your login function will work, you can do it in many ways, I will demonstrate 3 examples and leave it up to you:
code :
SELECT `user_id`, `email`, `username`, `password` FROM `users`......etc...
SELECT * FROM `users`......etc...
$stmt->bind_result($id);
$result = $stmt->fetch();
$output = $stmt->get_result();
while ($row = $output->fetch_array(MYSQLI_NUM))
{
    $result = $row;
}
print_r(login("user", "1234"));
Array ( [0] => 1 [1] => user@user.com [2] => user [3] => 1234 ) 
$stmt->bind_result($id);
$result = $stmt->fetch();
$stmt->bind_result($db_user_id, $db_email, $db_username, $db_password);
$stmt->fetch();
$stmt->bind_result($id);
$result = $stmt->fetch();
$stmt->bind_result($db_user_id, $db_email, $db_username, $db_password);
while ($stmt->fetch()) {
    echo $db_user_id;
}

seems to work fine The problem is the space between max and (. From the documentation:
code :
SELECT coalesce(max(p_order), 0) + 1 AS new FROM pages
