【问题描述】：

我在共享主机上更新更多图像时遇到问题，但在我的本地计算机上一切正常

我的共享主机出现此错误。

file_put_contents(/public/storage/article_image/post_162069532710.png): failed to open stream: No such file or directory

这是我的更新功能

        $detail=$request->messageInput;
        $dom = new \domdocument('1.0', 'UTF-8');
        @$dom->loadhtml('<?xml encoding="UTF-8">'.$detail);
        libxml_use_internal_errors(true);
      
        $images = $dom->getelementsbytagname('img');
        $bs64='base64';//variable to check the image is base64 or not
       
        foreach($images as $k => $img)
            $data = $img->getattribute('src');
            if (strpos($data,$bs64) == true)//if the Image is base 64
            
                $data = base64_decode(preg_replace('#^data:image/\w+;base64,#i', '', $data));
                $image_name = "/storage/article_image/". 'post_' . time() . $k . '.png';
                $path = public_path() . $image_name;
                file_put_contents($path, $data);
                $img->removeAttribute('src');
                $img->setAttribute('src', $image_name);
                
                else
                
                    $image_name="".$data;
                    $img->setAttribute('src', $image_name);
                
              ;
              $detail = $dom->savehtml();

        $article=Article::find($id);
        $article->articlecategory_id=$request->articlecategory_id;
        $article->title=$request->title;
        $article->keyword=$request->keyword;
        $article->shortdetail=$request->shortdetail;
        $article->fulldetail = $detail;
        $article->updated_by=Auth::id();
        $article->status_id=$request->status_id;

        $article->save();

表单上传

                                        <div class="mx-auto col-md-8">
                                            csrf_field()
                                            <textarea name="messageInput" class="summernote" minlength="300" maxlength="5100" required>$articles->fulldetail</textarea>
                                            <span class="text-danger"> $errors->first('fulldetail') </span>
                                        </div>

我已经坚持了大约 2 天。请帮忙：[

【参考方案1】：

file_put_contents 如果您尝试将文件放在不存在的目录中，则会失败。在本地，您有目录/public/storage/article_image/，因此您不会收到此错误，但在共享主机中您不会。在将数据写入文件之前，您应该检查目录是否存在。

   $data = base64_decode(preg_replace('#^data:image/\w+;base64,#i', '', $data)); 
   $dir = public_path() . "/storage/article_image";
    if( !is_dir( $dir ) ) 
        mkdir( $dir, 0777, true ); 
    
    $path = $dir. '/post_' . time() . $k . '.png';
    file_put_contents($path, $data);
