php - 如何在 Yii 中使用 xupload

Question

我是 Yii 新手，想集成文件上传。不幸的是，我无法让它工作。我已经下载插件并将其解压缩到 /extensions/ 文件夹，但现在我不知道该怎么做。

有人可以指导我吗？

该扩展已过时且支持不佳。我改用这个扩展名：eajaxupload。

正如您在该页面上看到的那样，用法非常简单。将其上传到您的扩展目录并使用这几行代码安装它

首先，您将以下代码放入控制器操作中：

public function actionUpload()
{
        Yii::import("ext.EAjaxUpload.qqFileUploader");

        $folder='upload/';// folder for uploaded files
        $allowedExtensions = array("jpg");//array("jpg","jpeg","gif","exe","mov" and etc...
        $sizeLimit = 10 * 1024 * 1024;// maximum file size in bytes
        $uploader = new qqFileUploader($allowedExtensions, $sizeLimit);
        $result = $uploader->handleUpload($folder);
        $result=htmlspecialchars(json_encode($result), ENT_NOQUOTES);

        $fileSize=filesize($folder.$result['filename']);//GETTING FILE SIZE
        $fileName=$result['filename'];//GETTING FILE NAME

        echo $result;// it's array
}

之后转到该操作的关联视图文件并使用此代码生成上传表单：

<? $this->widget('ext.EAjaxUpload.EAjaxUpload',
array(
        'id'=>'uploadFile',
        'config'=>array(
               'action'=>'/controller/upload',
               'allowedExtensions'=>array("jpg");//array("jpg","jpeg","gif","exe","mov" and etc...
               'sizeLimit'=>10*1024*1024,// maximum file size in bytes
               'minSizeLimit'=>10*1024*1024,// minimum file size in bytes
               //'onComplete'=>"js:function(id, fileName, responseJSON){ alert(fileName); }",
               //'messages'=>array(
               //                  'typeError'=>"{file} has invalid extension. Only {extensions} are allowed.",
               //                  'sizeError'=>"{file} is too large, maximum file size is {sizeLimit}.",
               //                  'minSizeError'=>"{file} is too small, minimum file size is {minSizeLimit}.",
               //                  'emptyError'=>"{file} is empty, please select files again without it.",
               //                  'onLeave'=>"The files are being uploaded, if you leave now the upload will be cancelled."
               //                 ),
               //'showMessage'=>"js:function(message){ alert(message); }"
              )
)); ?>

非常容易上手。搏一搏！

要在保存图像之前更改文件名，请取消注释行并提供您选择的名称。

./extensions/EAjaxUpload/qqFileUploader.php

    $pathinfo = pathinfo($this->file->getName());
    $filename = $pathinfo['filename'];
    //$filename = md5(uniqid());
    $ext = $pathinfo['extension'];
