How to insert data from shopping cart into the DB - php

I made simple shopping cart using PHP for my website, so now I need to take data from that shopping cart and the form and send it to the DB. I tried writing the code myself but it doesn't work, when I press the submit button nothing happens. What could be the problem?
This is the code I have:
Index.php:
<?php
session_start();
$connect = mysqli_connect("localhost", "root", "", "tut");
?>

My attempt at sending data into the database:
<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "tut";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "INSERT INTO tut (p_name, image, price)
VALUES ('{$mysqli->real_escape_string($_POST['ime'])}')";
if ($conn->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
?>

submit button is placed outside the form tag, make sure your data is submitted

Shopping Cart only enters last item in Database not all of the data

I am having an issue with my shopping cart when I add three items only the last item enters into the database. I am not sure how to get all the items to insert into the database like 3 or 4. I have tried many different ways and still come up with nothing. I still have to also figure how to get subtotal and customer name to attach to the orders
Index.php
<?php
session_start();
require_once("dbcontroller.php");
$db_handle = new DBController();
if(!empty($_GET["action"])) {
switch($_GET["action"]) {
case "add":
if(!empty($_POST["quantity"])) {
$productByCode = $db_handle->runQuery("SELECT * FROM tblproduct WHERE code='" . $_GET["code"] . "'");
$itemArray = array($productByCode[0]["code"]=>array('name'=>$productByCode[0]["name"], 'code'=>$productByCode[0]["code"], 'quantity'=>$_POST["quantity"], 'price'=>$productByCode[0]["price"]));
if(!empty($_SESSION["cart_item"])) {
if(in_array($productByCode[0]["code"],array_keys($_SESSION["cart_item"]))) {
foreach($_SESSION["cart_item"] as $k => $v) {
if($productByCode[0]["code"] == $k) {
if(empty($_SESSION["cart_item"][$k]["quantity"])) {
$_SESSION["cart_item"][$k]["quantity"] = 0;
}
$_SESSION["cart_item"][$k]["quantity"] += $_POST["quantity"];
}
}
} else {
$_SESSION["cart_item"] = array_merge($_SESSION["cart_item"],$itemArray);
}
} else {
$_SESSION["cart_item"] = $itemArray;
}
}
break;
case "remove":
if(!empty($_SESSION["cart_item"])) {
foreach($_SESSION["cart_item"] as $k => $v) {
if($_GET["code"] == $k)
unset($_SESSION["cart_item"][$k]);
if(empty($_SESSION["cart_item"]))

That's because your submit form doesnt support multiple fields.
You have to add a index to each inputs' name.
<?php
$i = 0;
foreach ($_SESSION["cart_item"] as $item){
?>
<tr>
<td style="text-align:left;border-bottom:#F0F0F0 1px solid;" ><input type="text" name="name[<?php echo $i; ?>]" value="<?php echo $item["name"]; ?>"></td>
<td style="text-align:left;border-bottom:#F0F0F0 1px solid;"><input type="text" name="code[<?php echo $i; ?>]" value="<?php echo $item["code"]; ?>"></td>
<td style="text-align:right;border-bottom:#F0F0F0 1px solid;"><input type="text" name="quantity[<?php echo $i; ?>]" value="<?php echo $item["quantity"]; ?>"></td>
<td style="text-align:right;border-bottom:#F0F0F0 1px solid;"><input type="text" name="price[<?php echo $i; ?>]" value="<?php echo $item["price"]; ?>"></td>
<td style="text-align:center;border-bottom:#F0F0F0 1px solid;">Remove Item</td>
</tr>
<?php
$item_total += ($item["price"]*$item["quantity"]);
$i++;

Very heavy wordpress plugin and customization

i have a wordpress website and with customization (cache/minify/database), is really quick in frontend, and in backend, with one exception. I use a plugin where it stores and retrieves players stats, carreers, teams etc.
When saving the team's match player's statistics, it needs 5 minutes to show the page reloaded with the data.
Also when retrieving for example team's season data, it also needs a lot of time to show them.
From what i ve seen, it is related with two of my files that do all the work. tournament_match.php, and functions.php. From hosting they said that it gets all tha database and thats why it is so slow
Here is the tournament_match file
<?php

Ajax Mysql PHP How to show $_SESSION arrays result into DIV

My friends,
I´m facing some hard trouble with Ajax & PHP integration. I have a simple code as below that returns the data from database and shows into div class="item-list". When the user puts the quantity and clicks on submit button, the selected item is uploaded into div class="returned", like the "add item to cart" function. The code is working as well (add & remove from list), but only with refresh on page.
I saw many examples on web and I tried to adapt them to my code (today is my third day of fighting), but with no success. Could you please show to me a way to load the selected items into div class="returned" without refresh on page?
Best regards & thanks a lot!

Your product price is RM6.90. Give only numbers to multiply.
If you want to find out the float no from product price, consider using regex.
This is the way u could do it
$productprice = "RM6.90";
preg_match('/([0-9]+\.[0-9]+)/', $productprice, $matches);
$floatproductprice = (float)$matches[0];// it will contain the float value
$floatproductprice should be used to calculate the total and also this value
should be stored in the database. Also change the type of price details and order total in database to Float or Double.
Your product price appears to have the literal "RM" in it as a suffix. This will cause PHP to abort number processing treating values as zeros.
You must remove non-numeric characters from your strings to make them true numbers. Something like the following may help. Kind of ugly, but simple use.
$capture_prefix = ""; #prefix for last number
function capture_number( $text )
{
global $capture_prefix;
$number = preg_replace( '/^[^\d]+/', "", $text );
$capture_prefix = substr( $text, 0, strlen($text) - strlen($number) );
return $number;
}

You need to initialize the variable in the code like this
require 'database.php';
$id = null;
if ( !empty($_GET['id'])) {
$id = $_REQUEST['id'];
}
if ( null==$id ) {
header("Location: index.php");
}
$category_category_id = "";
$category_name = "";
if ( !empty($_POST)) {
// keep track validation errors
$category_nameError = null;
$category_category_idError = null;
// keep track post values
$category_category_id = $_POST['id'];
$category_name = $_POST['category_name'];
// validate input
$valid = true;
if (empty($category_name)) {
$category_nameError = 'Please enter Category name';
$valid = false;
}
if (empty($category_category_id)) {
$category_idError = 'Please enter Category id';
$valid = false;
}
// update data
if ($valid) {
$pdo = Database::connect();
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "UPDATE category set id = ?, category_name = ? WHERE id = ?";
$q = $pdo->prepare($sql);
$q->execute(array($category_category_id,$category_name,$id));
Database::disconnect();
header("Location: index.php");
}
} else {
$pdo = Database::connect();
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "SELECT * FROM category where id = ?";
$q = $pdo->prepare($sql);
$q->execute(array($id));
$data = $q->fetch(PDO::FETCH_ASSOC);
$category_category_id = $data['id'];
$category_name = $data['category_name'];
Database::disconnect();
}
also change the input field name
<input name = "category_name" id="catogortId" type = "text" placeholder = "Category Name" value = "<?php echo !empty($category_name)?$category_name:'';?>">
You don't have put name attribute value in form so put it like :
<input name="category_name" type="text" placeholder="Category Name" name="category_name" value="<?php echo !empty($category_name)?$category_name:'';?>">
You do not have category_name field.
Change:
<input name="category_id" type="text" placeholder="Category Name" value="<?php echo !empty($category_name)?$category_name:'';?>">
To
<input name="category_name" type="text" placeholder="Category Name" value="<?php echo !empty($category_name)?$category_name:'';?>">
You need to change name = "category_id" to name = "category_name" in updateCategory.php file
Change
<input name = "category_id" type = "text" placeholder = "Category Name" value = "<?php echo !empty($category_name)?$category_name:'';?>">
TO
<input name = "category_name" type = "text" placeholder = "Category Name" value = "<?php echo !empty($category_name)?$category_name:'';?>">
