使用POST传递序列化数组会产生意想不到的结果

我的目标是通过POST传递数组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。

它工作正常，因为我能够看到另一个页面上的数组，但是当我尝试访问主数组内的嵌套数组时，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，但是对于内部数组我得到“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?>'>

....那么其他页面上：

// 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。

这是串行化之前的输出：（$车和产品内购物车的输出。）

{ "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": [] }

，系列化后发送：

{ "__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

在尝试反序列化之前，您是否验证过$ _POST [cartserialized]在另一页上是否有内容？ – tjfo

使用var_dump，检查是否只是在对象序列化中做了浅拷贝或深层拷贝。 – Bonatti

是的。它有数据，你可以在输出中看到（问题编辑）。唯一的区别是我不知道它来自哪里的附加关键字（值）“__PHP_Incomplete_Class_Name”。至于浅拷贝或深拷贝，我不知道你在说什么Bonatti。多谢你们。 – ILemus

为了反序列化一个PHP中的对象，你需要先加载这个类。因此，请包含定义此对象类型的脚本，然后反序列化。

有关进一步参考，请参阅[对象序列化]（http://php.net/manual/en/language.oop5.serialization.php）。 – showdev

谢谢你们。

我试着使用json_encode和json_decode在其他论坛建议，它似乎工作更好，我没有问题发送和检索另一端的数据。

感谢您宝贵的时间。
