TP5.0整合webuploader實現多圖片上傳功能

時間 2019-11-09

標籤 tp5.0 整合 webuploader 實現圖片上傳功能简体版

原文原文鏈接

在https://github.com/fex-team/webuploader 下載webuploader並解壓，
解壓後放到public裏面。其中我把解壓縮後的文件夾更名爲webuploader，放到了public/static/文件夾下。javascript

將你放到public下的webuploader文件夾中的examples/imageupload/index.html複製到在對應須要文件上傳功能的視圖文件夾下面
將其中的css和js文件路徑進行替換，ThinkPHP5.0中 __STATIC__直接指向了項目下的public/static文件下
下面這裏的有點長，若是須要知道哪段是本身添加的可搜索 ‘本身添加的’
這幾個字，有註釋的php

若是直接引入的upload.js,而不是直接粘過來的話
就須要找到webuploader/examples/imageupload/upload.js文件，在第154行，或者搜索server，將後臺地址改成你想要的地址（其實就是指的文件上傳的方法的地址），個人改爲了’imgupload’ 注意通過我屢次試驗，’{:url(「」)}’助手函數不會被解析，這裏不能使用。css

效果：html

文件上傳的後臺方法
將ThinkPHP5文檔中關於圖片上傳的代碼寫進去，將請求的名稱改爲file。java

public function imgupload()
    {
         $file = request()->file('file');
       // 移動到框架應用根目錄/public/uploads/ 目錄下
           $info = $file->move(ROOT_PATH . 'public' . DS . 'uploads');
          if($info){
               // 成功上傳後 獲取上傳信息
               // 輸出 jpg
             
                $data['path']=str_replace('\\',"/","/uploads/".$info->getSaveName()); 
                
                return json_encode($data['path']);//把路徑ajax用json方式返回到視圖中
               
           }else{
               // 上傳失敗獲取錯誤信息
               echo $file->getError();
           }
           
           
    }
