How to create&display cart via a php script

[BenDev]

Hello,

 

I have to send a request to a script on my server in order to create and display a cart for my PrestaShop : 1.7.1.1 .

An old script exist (for an older version of Prestashop) and I wanted to modify it but I've got an issue with this :

<?php
require_once('config/config.inc.php');
include_once('classes/Cookie.php');
require_once('vendor/autoload.php');
$context = Context::getContext();
$debug = fopen("debug.txt", "a");
$cookie  = $context->cookie;
$id_cart = $cookie->id_cart;

fwrite($debug, "Context = ");
fwrite($debug, json_encode($context));
fwrite($debug, "Cookie = ");
fwrite($debug, json_encode($cookie));

$basketHeader = "Location: https://www.my-site.com/fr/panier";

$products_type_max = 5;
$basket = array();

if(!empty($_GET)){
	fwrite($debug, "GET = ");
	fwrite($debug, json_encode($_GET));
	foreach($_GET as $key=>$value){
		$basket[$key]=preg_replace("/[^0-9]/", "", $value);
	}
	fwrite($debug, "Basket = ");
	fwrite($debug, json_encode($basket));

	if(count($basket) != (2 * $products_type_max) ){
		header($basketHeader);
		exit();
	}
}
else{
	header($basketHeader);
	exit();
}

if (isset($basket))
{
	if ($cookie->id_cart)
	{
		$cart = new Cart($cookie->id_cart);
	}

	if(!isset($cart) OR !$cart->id){
		$cart = new Cart();
		$cart->id_shop_group = 2;
		$cart->id_shop = 1;
		if(!isset($cookie->id_customer)){
			$cart->id_customer = 0;
			$cart->id_address_delivery = 0;
		} else {
			$cart->id_customer = (int)($cookie->id_customer);
			$cart->id_address_delivery = (int)(Address::getFirstCustomerAddressId($cart->id_customer));
		}
		$cart->id_guest=(int)($cookie->id_guest);
		$cart->id_address_invoice = $cart->id_address_delivery;
		$cart->id_lang = (int)($cookie->id_lang);
		$cart->id_currency = 1;
		$cart->id_carrier = 0;
		$cart->recyclable = 0;
		$cart->gift = 0;
		$cart->add();
		$cookie->id_cart = (int)($cart->id);    
		$cart->update();
	}
	
	for($i=0;$i<$products_type_max;$i++){
		if($basket['qty'.$i]>0){
			$cart->updateQty($basket['qty'.$i],$basket['id'.$i]);
		}
	}

	if(!($cart->containsProduct(13))){
		$cart->updateQty(1,13);
	}

	fwrite($debug, "Cart = ");
	fwrite($debug, json_encode($cart));

	fclose($debug);
	header($basketHeader);
	exit();
}

This script get the parameters, create a cart in prestashop but when i redirect the user... the cart page is empty.
I can see the abandoned cart in the admin, but the user/visitor have nothing shown...

Problem with cookie/session ? Can you guide/hep me ?
 

PS: I'm more a JS developper, and i have put many debug log in this script to help my research ^^' sorry if it bother you

 

Best regards,

Hello,

<?php
require_once('config/config.inc.php');
include_once('classes/Cookie.php');
require_once('vendor/autoload.php');

ini_set("display_errors", 1);

$debug = fopen("debug.txt", "a");
$context = Context::getContext();


$basketHeader = "Location: https://www.my-site.com/fr/panier";

$products_type_max = 5;
$basket = array();

/**
 * Get the infos or redirect
 */
if(!empty($_GET)){
	foreach($_GET as $key=>$value){
		$basket[$key]=preg_replace("/[^0-9]/", "", $value);
		//fwrite($debug, $key. ' = '.$basket[$key]);
	}
	
	if(count($basket) != (2 * $products_type_max) ){
		header($basketHeader);
		exit();
	}
}
else{
	header($basketHeader);
	exit();
}

fwrite($debug, json_encode($context));

/**
 * Try to set basket
 */
if (isset($basket))
{
	if (is_null($context->cart)) {
    $context->cart = new Cart($context->cookie->id_cart);
		$context->cart->id_shop_group = 1;
		$context->cart->id_shop = 1;
		if(!isset($cookie->id_customer)){
			$context->cart->id_customer = 0;

		} else {
			$context->cart->id_customer = (int)($cookie->id_customer);
			$context->cart->id_address_delivery = (int)(Address::getFirstCustomerAddressId($context->cart->id_customer));

		$context->cart->update();
	}
	
	for($i=0;$i<$products_type_max;$i++){
		if($basket['qty'.$i]>0){
			$context->cart->updateQty($basket['qty'.$i],$basket['id'.$i]);
		}
	}

	if(!($context->cart->containsProduct(13))){

	}

	fwrite($debug, "Cart = ");
	fwrite($debug, json_encode($context->cart));

	fclose($debug);
	
	header($basketHeader);
	exit();
}

Add the modified code (display cart not working yet) (see edit history)

[BenDev]

How can I redirect the user to cart page without loosing all my context ?

or have I to use another function to redirect with parameters ?

It's so frustrating to have no clue, no useful documentation and so few helpers (thanks to ndiaga for the message)
