Question

我正在尝试使用Jquery将json文件传递给PHP。当我检查响应时，我得到错误json_decode期望参数1是一个字符串。

这是我的jquery例程

 $("#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 
}); 
});

这是我的PHP脚本

<?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>";
}

?>

这是我的json对象

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

使用php小提琴我创建并测试了这个完美运行的脚本

<?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>";
}

?>

我注意到的一件事是我的php fidle json文件有[]发布的对象不是这个错误消息引用的吗？或者我不应该JSON.stringfy（）并将其作为字符串传递给php并使用JSON_encode？

感谢您的帮助

JSON.stringify返回编码的字符串。您必须发布其返回的值，而不是传递给它的参数。

// 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 
}); 
});

将json文件发布到PHP
