Question

我是php新手我有基于jquery / javascript的应用程序，它涉及查找附近的地方并按排序顺序给出结果。我正在尝试将排序功能从html页面分离到服务器端php。

它涉及向＆＃34; http://thewebby.net16.net/SortJson.php 发送和ajax请求＆＃34; ，json数组作为参数
解析json请求并对其进行排序

基于这些SO问答

Jquery的

    $.ajax({
        type: "POST",
        dataType: "json",
        url: "/SortJson.php",
        data: {myData:datas},
        success: function(data){
            alert('Items added');
        },
        error: function(e){
            console.log(e.message);
        }
});

PHP

<?php

if(isset($_POST['myData'])){
 $obj = $_POST['myData'];
 //some php operation
 $jsonIterator = new RecursiveIteratorIterator(
    new RecursiveArrayIterator(json_decode($obj, TRUE)),
    RecursiveIteratorIterator::SELF_FIRST);

foreach ($jsonIterator as $key => $val) {
    if(is_array($val)) {
        echo "$key:\n";
    } else {
        echo "$key => $val\n";
    }
}
}else{
 echo "File Working";
}
?>

该页面位于http://thewebby.net16.net 在搜索对象按钮期间检查网络活动时，应该进行ajax调用。但是当我在chrome开发人员工具中检查网络活动时它没有发生

编辑： -

$.post( "SortJson.php",{myData:datas} , function( data ) {
 alert('Items added'+data);

});

当使用$ .post而不是$ .ajax方法工作时，请求正在发送。但是在服务器端，php文件总是进入其他情况

if(isset($_POST['myData'])){..}
else{
 echo "File Working";
}

如何解析php中的以下数据，我收到Invalid参数错误，传递的变量既不是对象也不是数组。更新网站中的代码$.Post而不是$.ajax

var_dump的结果

array (
  0 => 
  array (
    'place' => 'GreenPepper',
    'Distance' => '0.487',
    'Lat' => '8.52699',
    'Lng' => '76.92419100000006',
  ),
  1 => 
  array (
    'place' => 'BAKE \'N\' COOL',
    'Distance' => '0.513',
    'Lat' => '8.527908',
    'Lng' => '76.92643599999997',
  ),
)

对于此json输入

[{"place":"GreenPepper","Distance":0.487,"Lat":8.52699,"Lng":76.92419100000006},{"place":"BAKE 'N' COOL","Distance":0.513,"Lat":8.527908,"Lng":76.92643599999997}]

Answer 1

数据不是json编码。它是由@Quentin指出的形式编码所以不使用Json Iterator我只使用它而没有编码到json作为正常的post参数

for ($row = 0; $row < sizeof($obj); $row++) {


echo $obj[$row]['place'];

}

Answer 2

在文件的开头使用此代码。

<?php
    $postdata = json_decode(file_get_contents("php://input"));
        foreach($postdata as $key => $value){
        $credentials[$key] = $value;
        };
     print_r($credentials) //should return you the php accessible array instead of object.//only for testing purpose


     /*
        You logic to check the database or anyother operation
     */
