使用ajax post方法不起作用的變量

除DeleteUser（id）以外的所有其他函數都不起作用我只能通過post方法傳遞第一個變量，我認爲這是我嘗試過很多次的「id」，並且在addRecord.php腳本它給了我使用ajax post方法不起作用的變量

PHP公告：未定義指數：ID1， PHP公告：未定義指數：date1的

和那張但對於 DeleteUser（ID），它工作正常我正在嘗試這個LINK教程，並替換了表格細節，並且很好地顯示了表格和按鈕也，但我不能從這個

function addRecord() { 
     // get values 
     var id = $("#id").val(); 
     var date = $("#date").val(); 
     var time = $("#time").val(); 
     var news = $("#news").val(); 

     // Add record 
     $.post("ajax/addRecord.php", { 
      id1:id, 
      date1:date, 
      time1:time, 
    news1: news   //if i give news1:"test" it does not work 
     }, function (data, status) { 
      // close the popup 
      $("#add_new_record_modal").modal("hide"); 

      // read records again 
      readRecords(); 

      // clear fields from the popup 
      $("#id").val(""); 
      $("#date").val(""); 
      $("#time").val(""); 
     $("#news").val(""); 
     }); 
    } 


    $(document).ready(function() { 
     // READ recods on page load 
     readRecords(); // calling function 
    }); 
    // READ records 
    function readRecords() { 
     $.get("ajax/readRecords.php", {}, function (data, status) { 
      $(".records_content").html(data); 
     }); 
    } 


    function DeleteUser(id) { 
     var conf = confirm("Are you sure, do you really want to delete User?"); 
     if (conf == true) { 
      $.post("ajax/deleteUser.php", { 
        id: id 
       }, 
       function (data, status) { 
        // reload Users by using readRecords(); 
        readRecords(); 
       } 
      ); 
     } 
    } 

    function GetUserDetails(id) { 
     // Add User ID to the hidden field for furture usage 
     $("#hidden_user_id").val(id); 
     $.post("ajax/readUserDetails.php", { 
       id:id 
      }, 
      function (data, status) { 
       // PARSE json data 
       var user = JSON.parse(data); 
       // Assing existing values to the modal popup fields 
       $("#update_id").val(user.id); 
       $("#update_date").val(user.date); 
       $("#update_time").val(user.time); 
    $("#update_news").val(user.news); 
      } 
     ); 
     // Open modal popup 
     $("#update_user_modal").modal("show"); 
    } 

    function UpdateUserDetails() { 
     // get values 
     var id = $("#update_id").val(); 
     var date = $("#update_date").val(); 
     var time = $("#update_time").val(); 
     var news = $("#update_news").val(); 

     // get hidden field value 
     var id = $("#hidden_user_id").val(); 

     // Update the details by requesting to the server using ajax 
     $.post("ajax/updateUserDetails.php", { 
     id:id, 
     news:news 
      }, 
      function (data, status) { 
         // hide modal popup 
       $("#update_user_modal").modal("hide"); 
       // reload Users by using readRecords(); 
       readRecords(); 
      } 
     ); 
    } 

    $(document).ready(function() { 
     // READ recods on page load 
     readRecords(); // calling function 
    });

下面的代碼添加記錄和更新記錄是用來顯示錶

插入的PHP腳本的工作我做了測試，但他們都沒有獲得這個職位的變量

顯示你'addrecord.php'和'deleteuser。 php'代碼請問 – Subi

試試這個阿賈克斯後的語法

$.ajax({ 
url: 'ajax/addrecords.php', 
data: {'id1' : id, 'news1':news, 'time1':time, 'date1':date}, 
type: 'post', 
dataType:'json', 
success: function(output) { alert(output); }, 
error: function(request, status, error){ alert("Error: Could not delete"); } 
});

[01-Jun-2017 18:23:20 UTC] PHP注意：未定義的索引：id1 /ajax/addRecord.php上線9 [01-Jun- 2017 18:23:20 UTC] PHP公告：未定義索引：date1 /ajax/addRecord.php 10行 [01-Jun-2017 18:23:20 UTC] PHP公告：未定義索引：time1/ajax/addRecord。 PHP在線11 [01-Jun-2017 18:23:20 UTC] PHP通知：未定義的索引：news1 in /ajax/addRecord.php 12行 – chriscka

這樣換行和onc e再次回顯php文件中的變量$ .post（「ajax/addRecord.php」，{「id1」：id，「date1」：date，「time1」：time，「news1」：news}' – Subi

同樣的錯誤發生，當我嘗試使用udpate函數的空值插入，但它也給新聞未定義的索引，但它得到正確的ID和正確的行更新 – chriscka
