POST json array with php and ajax - PROBLEM

Question

I can not understand how I can pass through scripts (below) an "action" variable and a "products" array created with php.

<?php
   $actionFile = "add";
   $products = array("Name product", "price", "sku", ....);
?>
<script>
    function uploadProducts() {
        var formData = new FormData();
        formData.append("action", <?php echo json_encode($actionFile); ?>);
        formData.append("products", <?php echo json_encode($products); ?>);

        $.ajax({
            type: 'POST',
            url: './controllers/uploadProductsController.php',
            data: formData,
            processData: false,
            contentType: false,
            beforeSend: function(){
                // Show image container
                //$("#loader").show();
                console.log("1");
            },
            success: function(response){
                //$('.response').empty();
                //$('.response').append(response);
                console.log("2");
                console.log(response);
            },
            complete: function(){
                // Hide image container
                //$("#loader").hide();
                console.log("3");
            }
        });            
    }
</script>

uploadProductsControlle.php (code below) I print the array as a single string and no as Array.

<?php
    include("../../functions.php");

    $action = $_POST['action'];
    $productsArr = $_POST['products'];
    $response = array();

    var_dump(json_encode($productsArr));  //ERROR THIS PRINT STRING

    foreach($productsArr as $product) {
        echo $product;
    }
    ?>

I need "products" as an array to do a cycle. Thanks

你应该使用 json_decode 函数

$productsArr = json_decode($_POST['products']);
