Question

我正在尝试从Yii框架中的注册表单上传图像。图像将保存在“img / avatar”文件夹中，图像名称应更改为用户名。我用于此的代码段如下：

//uploading avatar to the img/avatar folder
$upload_file = CUploadedFile::getInstance($personModel, 'picture');
$personModel->picture = $upload_file;
$picture_name = $userModel->username;
$personModel->picture = $picture_name;
if(isset($upload_file))
{
    $upload_file->saveAs(Yii::app()->basePath.'/../img/avatar'.$picture_name);
}
$personModel->save();
//end of image uploading part

问题是：用户名已保存在数据库的图片行中。但图像未上传到该文件夹。我试图找出代码中的问题。但无法解决它。有什么建议吗？

Answer 1

首先，您需要做的是在未保存图片时阻止数据库输入。

if(isset($uploadedfile))
{
      if($upload_file->saveAs(Yii::app()->basePath.'/../img/avatar'.$picture_name)
      {
                 $personModel->save();                
      }
      else
      {
           //throw error
      }
}

就代码中的问题而言。最常见的问题是目录不存在，它们的路径不正确。

$upload_file = CUploadedFile::getInstance($personModel, 'picture');
$ext = pathinfo($upload_file->picture, PATHINFO_EXTENSION);
$picture_name = $userModel->username . '.' . $ext;
$personModel->picture = $picture_name;
if(isset($upload_file))
{
    $upload_file->saveAs('/Your_correct_path/.../etc/'.$picture_name);
}
$personModel->save();

select
    chr(27)||'[35m'||chr(27)||'[1;'||to_char(rownum+29)||'mTest' d
 ,  chr(27)||'[36m'||chr(27)||'[1;'||to_char(rownum+29)||'mTest' e
 ,  chr(27)||'[37m'||chr(27)||'[1;'||to_char(rownum+29)||'mTest' f
 ,  chr(27)||'[38m'||chr(27)||'[1;'||to_char(rownum+29)||'mTest' g
 ,  chr(27)||'[39m'||chr(27)||'[1;'||to_char(rownum+29)||'mTest' h
from dual
    connect by level<=5

您必须检查文件夹权限。

Answer 4

问题已通过以下代码解决：

$uploadFile = CUploadedFile::getInstance($personModel, 'picture');
$extension = pathinfo($uploadFile, PATHINFO_EXTENSION);
$fileName = $userModel->username . '.' . $extension;

if (isset($uploadFile)) {
    $personModel->picture = $fileName;
    $uploadFile->saveAs(Yii::app()->basePath . '/../img/avatar/' . $fileName);
}

在Yii框架中将图像上传到自定义名称
