使用Ajax发布PHP对象数组

Question

大家好我无法弄清楚我做错了什么，我有一个文件的对象数组并试图通过另一个php文件使用ajax来传递该数组

我的php对象数组是

Array
(
    [0] => Files Object
        (
            [id] => 39
            [case_id] => 35
            [file_name] => 5M UK Limited - Annual progress report 2017.pdf
            [file_path] => 5MUK01C/5M UK Limited - Annual progress report 2017.pdf
            [file_size] => 5233880
            [file_type] => application/pdf
            [file_date] => 2017-04-25 10:28:28
            [downloads] => 11
            [temp_path:Files:private] => 
            [upload_dir:protected] => /Users/johnfieldsend/Library/Mobile Documents/com~apple~CloudDocs/Web Development/document.center.new/httpdocs/uploads
            [upload_errors:protected] => Array
                (
                    [0] => No Errors.
                    [1] => Larger then upload_max_filesize - Try to reduce the sizre of your file.
                    [2] => Larger than the MAX_FILE_SIZE - Try to reduce the sizre of your file.
                    [3] => Partial upload.
                    [4] => No file.
                    [6] => No template directory.
                    [7] => Can't write to disk
                    [8] => File type not allowed, please upload either a word or pdf file.
                )

            [errors] => Array
                (
                )

        )

    [1] => Files Object
        (
            [id] => 40
            [case_id] => 35
            [file_name] => Notice to opt out 5M UK Limited.pdf
            [file_path] => 5MUK01C/Notice to opt out 5M UK Limited.pdf
            [file_size] => 182099
            [file_type] => application/pdf
            [file_date] => 2017-04-25 10:32:54
            [downloads] => 4
            [temp_path:Files:private] => 
            [upload_dir:protected] => /Users/johnfieldsend/Library/Mobile Documents/com~apple~CloudDocs/Web Development/document.center.new/httpdocs/uploads
            [upload_errors:protected] => Array
                (
                    [0] => No Errors.
                    [1] => Larger then upload_max_filesize - Try to reduce the sizre of your file.
                    [2] => Larger than the MAX_FILE_SIZE - Try to reduce the sizre of your file.
                    [3] => Partial upload.
                    [4] => No file.
                    [6] => No template directory.
                    [7] => Can't write to disk
                    [8] => File type not allowed, please upload either a word or pdf file.
                )

            [errors] => Array
                (
                )

        )

)

此数组存储在变量$files

中

我试图通过ajax将此代码传递给我的charts.php文件，代码为

  var jsonData = $.ajax({
      type: 'POST',
      url: '/ajax/process/charts.php?chart=files',
      data: <?php echo json_encode($files, true) ?>,
      dataType: "json",
      async: false
    }).responseText;

如果我检查页面，我可以看到我的数组的json字符串被传递给ajax

type: 'POST',
  url: '/ajax/process/charts.php?chart=files',
  data: [{"id":"39","case_id":"35","file_name":"5M UK Limited - Annual progress report 2017.pdf","file_path":"5MUK01C\/5M UK Limited - Annual progress report 2017.pdf","file_size":"5233880","file_type":"application\/pdf","file_date":"2017-04-25 10:28:28","downloads":"11","errors":[]},{"id":"40","case_id":"35","file_name":"Notice to opt out 5M UK Limited.pdf","file_path":"5MUK01C\/Notice to opt out 5M UK Limited.pdf","file_size":"182099","file_type":"application\/pdf","file_date":"2017-04-25 10:32:54","downloads":"4","errors":[]}],
  dataType: "json",
  async: false

但我无法访问charts.php

中的任何数据

我的回复是

array(1) {
  ["undefined"]=>
  string(0) ""
}

Answer 1

问题可能如下：

也许在AJAX调用中没有正确定义数据，请尝试以下方法：

var jsonData = $.ajax({
      type: 'POST',
      url: '/ajax/process/charts.php?chart=files',
      data: { 
           "myArray": '<?php echo json_encode($files) ?>'
      }
      dataType: "json",
      async: false
}).responseText;

并尝试使用（在charts.php中）回显它：

echo json_decode($_POST['myArray']);

我在2天前遇到了类似的问题，但我的解决方案有所不同，我发送了这样的数组：

data { "myArray": '<?php echo urlencode(json_encode($myArray));?>' }

然后像这样抓住它：

json_decode(urldecode($_POST['myArray']));

希望有所帮助
