Question

i) 具有发送数据守则

  var test={imagename:"apple.jpg",x:"13",y:"33"};

  $.ajax({
 type: "POST",
     url: "some.php",
     data: test,
     success: function(response){
    console.log(response);
    }
   });

但是,现在我想向综合系统提供多种数据。我的《加拿大法典》就是这样。

print $_POST[ imagename ];

i think of an approach like this var test={imagename:"apple.jpg|hen.jpg",x:"13|44",y:"33|22"}; and on php getting $_POST[ imagename ] then split it according to | but i am not liking semantic approach of it.
1-Does any one know better solution?
2-Please provide both javascript,jquery and php code for answer.
3-One final question is this notation called json var test={imagename:"apple.jpg",x:"13",y:"33"};
Thanks

Answer 1

一个阵列是这方面最有意义的解决办法,如 Java文:

var data = [
    {imagename:"apple1.jpg", x:"13", y:"33"},
    {imagename:"apple2.jpg", x:"51", y:"84"},
    {imagename:"apple3.jpg", x:"79", y:"57"}
];

修改如下:

$.ajax({
     type: "POST",
     url: "some.php",
     data: {data: data},
     success: function(response){
         console.log(response);
     }
 });

并且,在公共卫生和社会福利部中,你能够做到:

<?
    print_r($_POST[ data ]); // dumps an array

    $filename1 = $_POST[ data ][0][ filename ]; // filename of item #1
?>

最后,var test={imagename: “apple.jpg”,x:“13”,y:“33”};只不过是一些 Java成文法。页: 1 JSON。尽管JSON像Javales(JS甚至位于JSON的Javagust),但它只不过是你再次寄出的特性。 JSON是数据转让的一种格式。当你“无包装”时(在 Java或PHP),就不再叫JSON。

@pimvdb:

foreach($_POST[ data ] as $data) {
    $filename = $data[ filename ];
    $width = $data[ x ];
    $height = $data[ y ];

    do_something_with_it($filename, $width, $height);
}

Answer 3

您可尝试使用nes物体,如:

var test={imagename:["apple.jpg","hen.jpg"],x:["13","44"],y:["33","22"]};

  $.ajax({
     type: "POST",
     url: "some.php",
     data: test,
     success: function(response){
       console.log(response);
     }
  });

Then from the PHP side, you should be able to access it as an array, by calling:

  $_POST[ image name ][index_num_here];

  Example:
  $_POST[ image name ][0] => "apple.jpg"

Answer 4

Use arrays. Javascript:

var data = {
    "images": [
          {name: "apple.jpg", x: 13, y:14},
          {name: "egg.jpg", x:14, y: 35}
    ]
};

$.ajax({
   type: "POST",
   url: "some.php",
   data: data,
   success: function(response){
     console.log(response);
   }
 });

PHP:

// First.
print $_POST[ images ][0][ name ] // Prints apple.jpg
// Second
print $_POST[ images ][1][ name ] // Prints egg.jpg

// Looping
foreach($_POST[ images ] as $image) {
    print $image[ name ];
    print $image[ x ];
    print $image[ y ];
}

您的榜样

var test={imagename:"apple.jpg",x:"13",y:"33"};

The following part is considered as JSON (JavaScript Object Notation):

{imagename:"apple.jpg",x:"13",y:"33"}

Every JSON string is valid JavaScript as well.

Answer 5

I ve 成功使用

var test={imagename: ["apple.jpg", "banana.png"],x:"13",y:"33"};
$.post( some.php , {data: JSON.stringify(test)}, function(respons) { ... });

在服务器上:

<?php
$data = json_decode(urldecode($_POST[ json ]), true);
echo $data[ imagename ][0];
echo $data[ imagename ][1];
?>
