Leverage JavaScript variables within JSON objects

I have a JavaScript variable that I want to use in a JSON format.

var add = mixItems[i][0] + "," + mixItems[i][1];
jQuery.getJSON("wp-content/plugins/proteinmixer/php/addtocart.php" , function(data){
});

Here is the PHP code:

require_once('../../../../wp-blog-header.php'); 
header('Content-Type:application/json'); 
global $woocommerce; 
$productId = 66; 
$quantity = 10; 
//$add = $productId.",".$quantity.""; 
//$add = add; 
$addtocart = $woocommerce->cart->add_to_cart($add); 
echo json_encode($addtocart);

We need to include the variable ADD in the JSON data.

Answer №1

To convert any JavaScript value or object into a JSON string, you can utilize the JSON.stringify() method:

var combined = mixItems[i][0] + "," + mixItems[i][1];
var jsonCombined = JSON.stringify(combined);
