發佈json文件到PHP

Question

我想通過JQuery將json文件傳遞給PHP。當我檢查響應時，我得到錯誤json_decode期望參數1是一個字符串。

這裏是我的jQuery常規

$("#ProcessData").click(function(){ 
var cols = $("#tblGroup thead tr th").map(function(){ 
return $(this).text(); }); 

var headers = cols; 

// Fetch the data from the table body 
var tableObject = $("#tblGroup tbody tr.tableClass").map(function(i){ 
var row = {}; $(this).find('td').each(function(i){ 
var rowName = headers[i]; 
row[rowName] = $(this).text(); 
}); 

return row; 

}).get(); 

// convert object to JSON 
JSON.stringify(tableObject); 

//now call ajax to pass info to php 

$.ajax({ 
url: 'php/ProcessOrder.php', 
data: {my_json_data: tableObject}, 
type: 'POST', 
async: false, 
dataType: 'json', cache:false 
}); 
}); 

這裏是我的PHP腳本

<?PHP 
//this is the layout of the json object 
//Title:First Name:Surname:Group Name this will needamending as the json object builds 

require("dbsettings.php"); 
$_Reference= $_POST["my_json_data"]; //this is a json object 
// Loop through Array 
$someArray = json_decode($_Reference, true); // Replace ... with your PHP Array 

foreach ($someArray as $key => $value) { 
echo $value["Title"] . ", " . $value["First Name"] . ", " . $value["Surname"] . ", " . $value["Group Name"] . "<br>"; 
} 

?> 

這裏是我的JSON對象

{"Title":"Mr","First Name":"12","Surname":"12","Group Name":"as"} 

使用PHP撥弄我創建並測試這個腳本完美工作

<?php 

$someJSON = '[{"name":"Jonathan Suh","gender":"male"},{"name":"William Philbin","gender":"male"},{"name":"Allison McKinnery","gender":"female"}]'; 


// Loop through Array 
$someArray = json_decode($someJSON, true); // Replace ... with your PHP Array 

foreach ($someArray as $key => $value) { 
echo $value["name"] . ", " . $value["gender"] . "<br>"; 
} 

?> 

有一件事我沒有通知我的PHP FIDLE JSON文件[]張貼的對象不會是這樣的錯誤信息是指什麼呢？或者我不應該JSON.stringfy（），只是將它作爲一個字符串傳入PHP並使用JSON_encode？

感謝您的任何幫助

JSON.stringify返回編碼的字符串。您必須發佈其返回的值，而不是傳遞給它的參數。

// convert object to JSON 
json = JSON.stringify(tableObject); 

//now call ajax to pass info to php 

$.ajax({ 
url: 'php/ProcessOrder.php', 
data: {my_json_data: json}, 
type: 'POST', 
async: false, 
dataType: 'json', cache:false 
}); 
});
