本文介绍了一个基于Yii框架的图片上传功能实现方法，并详细解释了如何使用FileHelper类来创建目录，确保图片能够成功上传到指定路径。此外，还提供了一个具体的getUploadedImagePath方法示例。

use yii\helpers\FileHelper;

if ($model->load(Yii::$app->request->post())) {
            #print_r(dirname$this->getUploadedImagePath());die;
    //E:\UPUPW_AP5.5\vhosts\www.jbp9.my/uploads\image\f0\8b\f08b2856079ba5066261682d8b5ddc0c.jpg
            if(FileHelper::createDirectory(dirname($this->getUploadedImagePath()))){
                print_r($this->getUploadedImagePath());
            }
}

public function getUploadedImagePath()
    {
        $file_tmp_name = $_FILES[ucwords(Yii::$app->controller->id)]['tmp_name']['image'];
        $this->hash = hash_file('md5', $file_tmp_name);
        $this->extension = 'jpg';
        $file_name = hash_file('md5', $file_tmp_name);
        #print_r($file_name."<br/>");
        return \Yii::getAlias('@attachmentPath') . DIRECTORY_SEPARATOR . 'image' . DIRECTORY_SEPARATOR . substr($this->hash, 0, 2) . DIRECTORY_SEPARATOR . substr($this->hash, 2, 2) . DIRECTORY_SEPARATOR . $this->hash .  '.' . $this->extension;
    }

这里写图片描述

官方文档
createDirectory() public method
Creates a new directory.
This method is similar to the PHP mkdir() function except that it uses chmod() to set the permission of the created directory in order to avoid the impact of the umask setting.
boolean createDirectory( $path,$ mode = 509, $recursive = true )$ path string
Path of the directory to be created.
$mode integer The permission to be set for the created directory.$ recursive boolean
Whether to create parent directories if they do not exist.
return boolean
Whether the directory is created successfully
createDirectory可递归创建目录并保存一次文件，但是保存后的文件删除后再次执行则没有保存。
