PHP null返回與json_decode

Question

由於某種原因我有一個所見即所得的編輯器生成的HTML json字段的問題。

我正在使用wordpress和angularJS，我試圖做一個窗體，更新某個職位。

使數據正常工作我正在做類似於服務器上的事情

$data = [ 
'title'=>$post->post_title, 
'description'=>$post->post_content // contains html via a WYSIWYG editor 
.... more stuff 
] 
header('Content-Type: application/json'); 
echo json_encode($data); 
exit; 

表單自動填充上述數據OK。

當我試圖通過將JSON.stringify（數據）返回給服務器來更新帖子時，問題就在發生。當我嘗試在服務器上執行json_decode（$ _ POST ['data']）時，我得到以下PHP錯誤，這是由於data.description的HTML內容而發生的。沒有data.description我的代碼工作正常更新後

json_last_error: 4 
json_last_error_msg: "Syntax error" 
json_decode($_POST['data']) == null 

但在Javascript中，當我做的console.log（JSON.stringify（數據））和驗證JSON數據是好的。我沒有使用魔術配額get_magic_quotes_gpc（）=> 0。我也試過stripslashes（$ _ POST ['data']）;

這個問題似乎很奇怪，因爲數據已成功轉換爲json的PHP，然後通過JavaScript解碼，但反向操作無法正常工作。當在服務器收到

值的console.log的（JSON.stringify（數據）），其是完整

$ _POST [ '數據']值.. JSON字符串是不完整的

更新 好吧我認爲這是'&'nbsp;在發送到服務器時打破json的HTML。如何從nbsp;消毒？ encodeURIComponent（）？或替換（）？

function ($http, globals) { 
    var request = { 
     method: 'POST', 
     url: globals.ajax_url, 
     headers: { 
      'Content-Type': 'application/x-www-form-urlencoded' 
     } 
    }; 
    return function (action, data) { 
     var queryStr = "action=" + action; 
     if (data) { 
      queryStr += "&data=" + JSON.stringify(data); 
     } 
     request.data = queryStr; 
     return $http(request); 
    }; 
} 

Answer 1

應該

echo json_encode($postdata); 

$postdata是變量的名稱，而不是$data

Answer 2

終於找到了解決方案。 我不得不添加encodeURIComponent，因爲& nbsp;通過tinymce WYSIWYG添加 - 在查詢字符串中會導致問題，如果不逃脫。

function ($http, globals) { 
      var request = { 
       method: 'POST', 
       url: globals.ajax_url, 
       headers: {'Content-Type': 'application/x-www-form-urlencoded'} 
      }; 
      return function (action, data) { 
       var queryStr = "action=" + action; 
       if (data) { 
        queryStr += "&data=" + encodeURIComponent(JSON.stringify(data)); 
       } 
       request.data = queryStr; 
       return $http(request); 
      };
