How can i display cart page in separate tab in php? - php

Here is my 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"],$_SESSION["cart_item"])) {
foreach($_SESSION["cart_item"] as $k => $v) {
if($productByCode[0]["code"] == $k)
$_SESSION["cart_item"][$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"]))
unset($_SESSION["cart_item"]);
}
}
break;
case "empty":
unset($_SESSION["cart_item"]);
break;
}

I need to display another tab for displaying shopping cart.
May i know, how can i do this? Thanks in advance.


If I read your instructions correctly, and I am not 100% sure I am, I think you want to only display the cart on add. To do this I think I would break your page up into parts so that each portion has a task. then you can more easily separate out your cart from your all-products display. You can also more-easily use the cart on other parts of the site since it is a class:
class.ShoppingCart.php
<?php

public function __construct($db)
{
$this->db = $db;
}

switch($_GET["action"]) {
case "add":
$this->AddToCart();
break;
case "remove":
$this->RemoveFromCart();
break;
case "empty":
$this->EmptyCart();
break;
}
}
}
public function AddToCart()
{
// I don't know if code is supposed to be numeric or not and I also
// don't know if you sanitize your input, but from just looking at this
// it looks dangerous (sql injection-prone)
if(!empty($_POST["quantity"]) && is_numeric($_GET["code"])) {
$productByCode = $this->db->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"]));

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

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: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>

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

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;
}

Answer:
if (!empty($_GET["bookID"])) {
foreach($_SESSION["cart_item"] as $subKey => $subArray){
if($subArray["bookID"] == $_GET["bookID"]){ /* CHECK IF THERE IS A BOOKID THAT HAS THE SAME $_GET["bookID"] */
unset($_SESSION["cart_item"][$subKey]);
}
} /* END OF FOREACH */
}
You store your array with sub-array of bName, bookID, quantity, and price in your session variable. The code I have provided will check the $_GET["bookID"] if it is in a sub-array of bookID. And if it does found one, it will remove that set of array.
[
{"bName":"Physics","bookID":"1","quantity":"1","price":"1100.00"},
{"bName":"Algebra","bookID":"2","quantity":"2","price":"1200.00"},
{"bName":"Calculus","bookID":"3","quantity":"3","price":"1300.00"}
]
Recommendation
Create an extra table. Lets name it cart_table
cart_id | userID | bookID |
---------+----------+----------+
1 | 1 | 1 |
2 | 1 | 2 |
3 | 1 | 3 |
userID column is the user's ID and bookID column is the book's ID that the user puts into the cart.
The advantage of this is even if the user logs-out, when this user returns, he/she will still be able to see the books that he/sher puts into his/her cart.

Can anyone help me to fix this, thanks in advance.

In your case you need to use another form with an input box that retrieve the quantity from user, Html5 has a input type number ( user can only add number ):
<input type="number" name="quantity" min="1" max="50" value="<?php echo $item["quantity"]; ?>">
- but it's for html5
for Xhtml & HTML4.01 you can use:
<input type="text" value="<?php echo $item["quantity"]; ?>" name="quantity">
& you also need a simple number validation by php using "is_numeric" function.
Hope i can help
