            </ul>
         </div>
        </div>

      </div>

用于更新评论的PHP代码如下

function updatereview_post($id=null){
{   
        $headers = apache_request_headers();
        {   
            if (empty($headers['authorization'])) {
               $info->status = 'failure';
               $info->error->code = 15;
                $info->error->text = 'basic HTTP AUTHENTICATION required';
                $this->response($info, 401);
         }
        }
    $string = base64_decode($headers['authorization']);

        list($username, $password) = explode(':', $string);

        {   
            $this->load->database();
            $sql  = 'SELECT COUNT(userid) AS records FROM users '.'WHERE authorization = "'.$headers['authorization'].'";';

            $query = $this->db->query($sql);
            $data = $query->row();
            if ($data->records == "0") {
                $info->status = 'failure';
                $info->error->code = 19;
                $info->error->text = 'authorization string is not valid';
                $this->response($info, 401);
            }
    }}
    {
if (!isset($id)){// check if the ID is specified in the URI
    $info->status = 'failure';
            $info->error->code = 11;
            $info->error->text = 'id not specified in URI';
            $this->response($info, 400);
}}
 {  // if the resource exist
        $this->load->database();
        $sql = 'SELECT COUNT(id) AS records FROM reviews WHERE id = '.$id.';';
        //$this->response($sql, 200);
        $query = $this->db->query($sql);
        $data = $query->row();
        if ($data->records == "0") {
            $info->status = 'failure';
            $info->error->code = 12;
            $info->error->text = 'id does not exist or have a resource';
            $this->response($info, 404);
        }
 }
$this->load->database();
$sql= 'SELECT * FROM reviews WHERE id= "'.$id.'";';
$query= $this->db->query($sql);
$data->old = $query->row();
$data->changes = $_POST;
$this->db->where('id', $id);
$this->db->set('reviews',$_POST);
$data->rows = $this->db->affected_rows();
$query= $this->db->query($sql);
$data->new = $query->row();
$this->response($data,200);
}

Answer 1

您的评论详细信息和更新表单应位于同一页面以便在代码下方工作。 看来在你的Getreviewid js函数中你需要添加这段代码：

success: function(data) {
    console.log(id);
    $("#reviewdetail").empty();
        $('#reviewdetail').append('<img src='+data.review.image+' style="width:150px; height:150px" , onerror="imgError(this);"</img>');
    $('#reviewdetail').append('<p><b>Title: </b>'+data.review.Title+'</p>');
    $('#reviewdetail').append('<p><b>Publisher: </b> '+data.review.publisher+'</p>');
    $('#reviewdetail').append('<p><b>Review: </b> '+data.review.review+'</p>');
    $("#r_id").val( data.review.id); // set review id for update form
    $.mobile.changePage("#detailreview"); //show the results page
    }

您不需要updateReviewForm函数。在updatereview函数中添加以下行：

data: {
review_id:  $("#r_id").val(),

在此之后，您可以在php页面中获取评论ID，如下所示：

  function updatereview_post($id=null){
     $id = $_REQUEST['review_id'];

我认为现在有道理：）
