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，图像的名称应更改为用户名。我为此使用的代码如下：
//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);
}
$personModel->save();
//end of image uploading part
问题是：用户名的名称已保存在数据库的图片行中。但是图像未上传到文件夹。我正在尝试找出代码中的问题。但无法解决。有什么建议吗？
那么，您需要做的第一件事是在图片未保存的情况下防止数据库输入。
if(isset($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();
$upload_file = CUploadedFile::getInstance($personModel, 'picture');
$picture_name = $userModel->username . '.' . pathinfo($upload_file, PATHINFO_EXTENSION);
$personModel->picture = $picture_name;
if (isset($upload_file)) {
$upload_file->saveAs(Yii::app()->basePath . '/../img/avatar/' . $picture_name);
}
$personModel->save();
您必须检查您的文件夹权限。
该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);
}
