Question

我发现这个示例代码使用ajax，php和sql编辑，更新和删除表中的行。

当我在localhost中运行此代码时，只有删除功能有效，所有其他功能都没有。

当我添加一行时，数据库中的行为空。

当我更新一行时，它总是使用第一行中的数据更新所有行。

任何人都可以帮我解决这个问题吗？ example can be found here

这是我的代码

<?php
 include 'configuration.php';
 include 'functions/functions.php';
 $action = $_REQUEST['action'];

 switch($action) {

 case "load":
    $query  = mssql_query('SELECT * FROM job_creation ORDER BY id ASC');
    $count  = mssql_num_rows($query);
    if($count > 0) {
        while($fetch = mssql_fetch_array($query)) {
            $record[] = $fetch;
        }
    }
    ?>
     <a href="gridder_addnew" 
    id="gridder_addnew" class="gridder_addnew">
    <img src=   "images/insert.png" alt="Add New" title="Add New" /></a>

    case "delete":
    $value  = decrypt($_POST['value']);
    $query = mssql_query("DELETE FROM Job_creation WHERE id = '$value' ");
    break;
  }
  ?>

注意：此示例在mySQL中有效，但我将其转换为MSSQL 非常感谢那些帮助我的人：）

解决问题插入（添加新内容）
替换此代码

<tr>
<td><input type="text" name="fname"
    id="fname"   class="gridder_add" /></td>
<td><input type="text" 
        name="lname" id="lname" class="gridder_add" /></td></tr>
case "addnew":
$fname      = isset($_POST['name_ar']) 
?   mssql_real_escape_string($_POST['name_ar']) : '';
$lname      = isset($_POST['name_en']) ?
mssql_real_escape_string    ($_POST['name_en']) : '';
mssql_query("INSERT INTO Job_creation (name_ar, name_en) 
VALUES ('$fname',  '$lname')");
break;

到此代码

<tr>
<td><input type="text" name="name_ar" id="name_ar" 
class="gridder_add" /> </td>
<td><input type="text" name="name_en" id="name_en" 
class="gridder_add" /></td></tr>
case "addnew":
    $fname      = $_POST['name_ar'];
    $lname      = $_POST['name_en'];
mssql_query("INSERT INTO Job_creation (name_ar, name_en) VALUES 
('$fname', '$lname')"); 
break;

解决问题更新
替换此代码

case "update":
$value  = $_POST['value'];
$crypto = decrypt($_POST['crypto']);
$explode = explode('|', $crypto);
$columnName = $explode[0];
$rowId = $explode[1];
$query = mssql_query("UPDATE Job_creation SET name_ar = 
'$value',name_en    = '$value' WHERE id = '$rowId' ");
break;

到此代码

    case 
   "update":
    $value  = $_POST['value'];
    $crypto = decrypt($_POST['crypto']);
    $explode = explode('|', $crypto);
    $columnName = $explode[0];
    $rowId = $explode[1];
    $query = mssql_query("UPDATE Job_creation SET 
    $columnName = '$value' WHERE id = '$rowId' ");
    break;
