HomeBackend DevelopmentPHP Tutorialthinkphp中一个方法调用另一个方法的变量

//实例化上传类     public function upload() {               $upload = new Upload();        $upload->maxSize = 10 * 1024 * 1024;        $upload->exts = array('jpg', 'jpeg', 'gif', 'txt','zip');        $upload->savePath = './';        $upload->hash = false;        $info = $upload->upload();        if (!$info) {            $this->error($upload->getError());        }         else{            foreach ($info as $file) {                $uploadFile=$file['savepath'].$file['savename'];                echo $uploadFile;            }                  }    }    //添加文章    public function addArticle(){    	 $sort = $_POST['sort'];    	 $title = $_POST['title'];    	 $intro = $_POST['intro'];    	 $pic = $_POST['pic'];    	 $content = $_POST['content'];       	 $articleSort= D('Article')->addArticle($sort,$title,$intro,$pic,$content);         $this->display('Index/AddArticle');    }

在做一个添加文章的功能。添加文章时用户可以先ajax无刷新上传文件,然后编辑文章后点发表文章按钮。有点类似QQ邮箱那种。
代码里 upload() 是上传文件的方法,addArticle()是添加文章的方法。
用户在上传文件时就会执行upload()方法把文件上传到指定的目录。我想用户在点击发布文章按钮时在addArticle()方法里获取upload()的变量$uploadFile,即用户上传文件的目录,然后和文章内容一起存储在数据库中。
简单来说我在addArticle()方法里要用到upload() 方法里的变量$uploadFile
求助各位大神


回复讨论(解决方案)

定义类属性。

由  添加文章时用户可以先ajax无刷新上传文件 可知
你的 upload 和 addArticle 是分开执行的
那么你就得在服务器上缓存 upload 的结果,在执行 addArticle 时取回

缓存这方法不错

用session缓存结果好么,还是用其他方法

用 session 是可以的,缓存的只不过是文件名而已
也可以在 ajax 上传后,将回传的文件名写入表单控件,之后再和表单一起提交

在你的这个架构中,需要考虑到一个问题:操作夭折时的垃圾回收(上传图片后又放弃提交了,此时上传的文件就成了孤儿)
给个方案供你参考:
上传的文件不直接放到上传目录中而是先放到一临时目录中,待表单正式提交后再从临时目录 rename 到上传目录
这样只需定时清空临时目录就可以了

xuzuning版主说的非常好,我没考虑到的操作夭折也给参考方案。现在问题解决了,谢谢大神!!

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
