使用 POST 传递序列化数组会产生意外结果

Question

我很困惑。

我的目标是通过 POST 将数组传递到另一个页面并访问它的数据。我找到了一种使用 serialize() 的方法。

它运行良好，因为我能够在另一页上看到数组，但是当我尝试访问主数组中的嵌套数组时，我没有得到预期的结果。换句话说，我可以访问主数组中的数据，但我得到的是内部数组的“null”。

让我告诉你我做了什么：

//The array:
    $cart = &JModelLegacy::getInstance('cart', 'jshop'); 
    $cart->load(); 

//I can access data of the inner array (the products) within the $cart array, for example:
    $productos = $cart->products;
    echo "<pre>".json_encode($cart, JSON_PRETTY_PRINT)."</pre>";        
    echo "<pre>".json_encode($productos[1], JSON_PRETTY_PRINT)."</pre>";        

//Then serializing it:
    $serializedcart = serialize($cart);

//Then sending it in a form using POST
    <input type='hidden' name='cartserialized' value='<?php print $serializedcart?>'>           

....然后在另一页上：

// I unserialize the transferred array:
$carretilla = unserialize($_POST[cartserialized]);

// And this doesn't work anymore, I get "null" for $productos:
$productos = $carretilla->products;
echo "<pre>".json_encode($carretilla, JSON_PRETTY_PRINT)."</pre>";      
echo "<pre>".json_encode($productos[1], JSON_PRETTY_PRINT)."</pre>";        

为什么？任何帮助将不胜感激。

这是序列化前的输出：（$cart 和购物车内产品的输出。）

{ "type_cart": "cart", "products": [ { "quantity": 1, "product_id": 329, "category_id": "17", "tax": null, "tax_id": "0", "product_name": "ATX Cromo Puro", "thumb_image": "thumb_882-2.jpg", "delivery_times_id": "0", "ean": "882-2", "attributes": "a:1:{i:1;i:28;}", "attributes_value": [ { "attr_id": 1, "value_id": 28, "attr": "Color", "value": "Cromo" } ], "extra_fields": [], "weight": "0.0000", "vendor_id": "1", "files": "a:0:{}", "freeattributes": "a:0:{}", "manufacturer": "Cross", "pid_check_qty_value": "A:218", "price": 570, "href": "\/index.php\/tienda\/product\/view\/17\/329", "free_attributes_value": [] }, { "quantity": 3, "product_id": 469, "category_id": "21", "tax": null, "tax_id": "0", "product_name": "Bater\u00eda Auxiliar", "thumb_image": "thumb_JK-PB035.jpg", "delivery_times_id": "0", "ean": "JK-PB035", "attributes": "a:0:{}", "attributes_value": [], "extra_fields": [], "weight": "35.0000", "vendor_id": "1", "files": "a:0:{}", "freeattributes": "a:0:{}", "manufacturer": null, "pid_check_qty_value": "P:469", "price": 265, "href": "\/index.php\/tienda\/product\/view\/21\/469", "free_attributes_value": [] } ], "count_product": 4, "price_product": 1365, "summ": 0, "rabatt_id": 0, "rabatt_value": 0, "rabatt_type": 0, "rabatt_summ": 0, "model_temp_cart": "tempcart", "price_product_brutto": 1365 } { "quantity": 3, "product_id": 469, "category_id": "21", "tax": null, "tax_id": "0", "product_name": "Bater\u00eda Auxiliar", "thumb_image": "thumb_JK-PB035.jpg", "delivery_times_id": "0", "ean": "JK-PB035", "attributes": "a:0:{}", "attributes_value": [], "extra_fields": [], "weight": "35.0000", "vendor_id": "1", "files": "a:0:{}", "freeattributes": "a:0:{}", "manufacturer": null, "pid_check_qty_value": "P:469", "price": 265, "href": "\/index.php\/tienda\/product\/view\/21\/469", "free_attributes_value": [] }

并在序列化和发送之后：

{ "__PHP_Incomplete_Class_Name": "jshopCart", "type_cart": "cart", "products": [ { "quantity": 1, "product_id": 329, "category_id": "17", "tax": null, "tax_id": "0", "product_name": "ATX Cromo Puro", "thumb_image": "thumb_882-2.jpg", "delivery_times_id": "0", "ean": "882-2", "attributes": "a:1:{i:1;i:28;}", "attributes_value": [ { "attr_id": 1, "value_id": 28, "attr": "Color", "value": "Cromo" } ], "extra_fields": [], "weight": "0.0000", "vendor_id": "1", "files": "a:0:{}", "freeattributes": "a:0:{}", "manufacturer": "Cross", "pid_check_qty_value": "A:218", "price": 570, "href": "\/index.php\/tienda\/product\/view\/17\/329", "free_attributes_value": [] }, { "quantity": 3, "product_id": 469, "category_id": "21", "tax": null, "tax_id": "0", "product_name": "Bater\u00eda Auxiliar", "thumb_image": "thumb_JK-PB035.jpg", "delivery_times_id": "0", "ean": "JK-PB035", "attributes": "a:0:{}", "attributes_value": [], "extra_fields": [], "weight": "35.0000", "vendor_id": "1", "files": "a:0:{}", "freeattributes": "a:0:{}", "manufacturer": null, "pid_check_qty_value": "P:469", "price": 265, "href": "\/index.php\/tienda\/product\/view\/21\/469", "free_attributes_value": [] } ], "count_product": 4, "price_product": 1365, "summ": 0, "rabatt_id": 0, "rabatt_value": 0, "rabatt_type": 0, "rabatt_summ": 0, "model_temp_cart": "tempcart", "price_product_brutto": 1365 } null

Answer 1

为了在 PHP 中反序列化一个对象，你需要先加载类。所以包括定义这个对象类型的脚本，然后反序列化。

Answer 2

谢谢你们。

我尝试按照其他论坛中的建议使用 json_encode 和 json_decode，它似乎工作得更好，并且我在另一端发送和检索数据没有问题。

感谢您宝贵的时间。
