如果添加的代码更新的图像和PDF更新查询不工作

Question

如果添加的代码上传图像和PDF更新查询不工作。我对INSERT和UPDATE除了prepare和execute相同的代码，插入查询工作很细，更新查询没有。我也曾在形成一个包括enctype="multipart/form-data"，这样我可以从$ _FILES获得的数据也是如此。此外，我已经使用$_FILES['photo']['tmp_name']和$_FILES['pdf']['tmp_name']为了使用功能move_uploaded_file move_uploaded_file($_FILES['photo']['tmp_name'], 'destination');和move_uploaded_file($_FILES['pdf']['tmp_name'], 'destination');移动它们

function edit_profile($pid)
{
    if($_SERVER['REQUEST_METHOD']=='POST')
    {
        echo "<pre>";
        print_r($_POST);
        print_r($_FILES);
        echo "</pre>";
        $fullname = $_POST['fullname'];
        $email = $_POST['email'];
        $contact = $_POST['contact'];
        $sel_post = $_POST['sel_post'];
        $txt_post = $_POST['post'];
        $post = "";
        if(empty($txt_post))
        {
            $post = $sel_post;
        }
        else
        {
            $post = $this->add_new_post($txt_post);
        }

        if(empty($fullname) || empty($contact))
        {
            array_push($this->errors, MEND_FIELD_ERROR);
            return;
        }

        if(!empty($_FILES['photo']['name']))
            {
                $photo = $_FILES['photo'];

                $allowed_size = 20000000;
                $tmp_photo = $photo['tmp_name'];
                $photo_size = $photo['size'];
                $photo_error = $photo['error'];
                $photo_ext = explode('.',$photo['name']);
                $photo_ext = strtolower(end($photo_ext));

                if(in_array($photo_ext,$allowed_ext))
                {
                    if($photo_size <= $allowed_size)
                    {
                        $photo_new_name = time()."_".uniqid('',true).'.'.$photo_ext;
                        $upload_destination = './cdn/uploads/profile/'.$photo_new_name;
                        if(move_uploaded_file($tmp_photo,$upload_destination))
                        {
                            $photo_to_db = $photo_new_name;
                        }
                        else
                        {
                            array_push($this->errors, STORAGE_ERROR);
                            return;
                        }

                    }
                    else
                    {
                        array_push($this->errors, $document_name.' : '.FILE_SIZE_ERROR);
                        return;
                    }
                }
                else
                {
                    array_push($this->errors, $photo_ext.' : '.FILE_EXT_ERROR);
                    return;
                }
            }

            if(!empty($_FILES['pdf']['name']))
            {
                $pdf = $_FILES['pdf'];
                $allowed_pdf_ext = array('pdf');
                $allowed_pdf_size = 20000000;
                $tmp_pdf = $pdf['tmp_name'];
                $pdf_size = $pdf['size'];
                $pdf_error = $pdf['error'];
                $pdf_ext = explode('.',$pdf['name']);
                $pdf_ext = strtolower(end($pdf_ext));

                if(in_array($pdf_ext,$allowed_pdf_ext))
                {
                    if($photo_size <= $allowed_pdf_size)
                    {
                        $pdf_new_name = time()."_".uniqid('',true).'.'.$pdf_ext;
                        $upload_pdf_destination = './cdn/uploads/profile_pdf/'.$pdf_new_name;
                        if(move_uploaded_file($tmp_pdf,$upload_pdf_destination))
                        {
                            $pdf_to_db = $pdf_new_name;
                        }
                        else
                        {
                            array_push($this->errors, STORAGE_ERROR);
                            return;
                        }

                    }
                    else
                    {
                        array_push($this->errors, $document_name.' : '.FILE_SIZE_ERROR);
                        return;
                    }
                }
                else
                {
                    array_push($this->errors, $photo_ext.' : '.FILE_EXT_ERROR);
                    return;
                }
            }

        $statement = $this->db->prepare("UPDATE `profiles` SET `fullname`=?,`email`=?,`contact`=?,`post`=?, `photo`=?, `pdf`=? WHERE `pid`=?");
        if($statement->execute([$fullname,$email,$contact,$post,$pid, $pdf_to_db, $photo_to_db]))
        {
            ExitThis::send_to(URL.'profile/view_profile?id='.$pid);
        }
        else
        {
            array_push($this->errors, DATABASE_ERROR);
            return;
        }
    }

}

仿佛更新查询工作正常，但数据仍保留在更新之前同上面的代码将返回我的view_profile页 - 没有变化。

编辑：执行它获得此之前调试$statement后：

PDOStatement Object
(
    [queryString] => UPDATE `profiles` SET `fullname`=?,`email`=?,`contact`=?,`post`=?, `photo`=?, `pdf`=? WHERE `pid`=?
)

Answer 1

这个问题可能是参数传递，按照顺序尝试错误的序列：

if($statement->execute([$fullname,$email,$contact,$post,$photo_to_db,$pdf_to_db,$pid]))

Answer 2

您通过使用错误的顺序变量execute方法。

...db->prepare("UPDATE `profiles` SET `fullname`=?,`email`=?,`contact`=?,`post`=?, `photo`=?, `pdf`=? WHERE `pid`=?");

而接下来你调用执行与这些变量：

...->execute([$fullname,$email,$contact,$post,$pid, $pdf_to_db, $photo_to_db]))

去年3应该像$photo_to_db, $pdf_to_db, $pid。您传递错误的PID，所以这就是为什么你没有看到更新的结果。

您也可以使用命名参数：http://php.net/manual/en/pdostatement.execute.php#example-1072

Answer 3

    $statement = $this->db->prepare("UPDATE `profiles` SET 
    `fullname`=?,`email`=?,`contact`=?,`post`=?, `photo`=?, `pdf`=? WHERE 
    `pid`=?");
     if($statement->execute([$fullname,$email,$contact,$post,$photo_to_db
     $pdf_to_db,$pid]))
     {
          ExitThis::send_to(URL.'profile/view_profile?id='.$pid);
       }
     else
    {
       array_push($this->errors, DATABASE_ERROR);
        return;
      }

删除您的更新语句$ PID，并检查您的参数，请试试这个代码
