资源说明：Yii extension for Plupload
This is an update to the Yii plupload extension found here:
http://www.yiiframework.com/extension/pupload/
Here is the list of changes:
* Updated Plupload to v1.3.0
* Fixed the DIRECTORY_SEPARATOR problem (to be checked, I'm not working with Windows presently)
* Added language option to config, to be used as 'language' => Yii::app()->language (see the example below). There are 3 supported languages in the i18n folder, but you can find more langauges in their forum http://www.plupload.com/punbb/viewforum.php?id=5
* Added max_file_number option to config, to limit the number of files (implemented as suggested here http://www.plupload.com/punbb/viewtopic.php?id=113 )
* Added autostart option to config, to autostart the upload after choosing files (implemented as suggested here http://www.plupload.com/punbb/viewtopic.php?id=90 )
* Added reset_after_upload to config, option to reset the file dialog after the upload is complete (implemented as suggested here http://www.plupload.com/punbb/viewtopic.php?id=192 )
* Added callbacks array, to be able to specify javascript callbacks for Plupload's Public Events (see documentation: http://www.plupload.com/plupload/docs/api/index.html#class_plupload.Uploader.html )
* Added jquery_ui to config, option to enable the jQuery UI theme (see: http://www.plupload.com/example_jquery_ui.php)
Here is an example of use with the new options:
$this->widget('application.extensions.plupload.PluploadWidget', array(
'config' => array(
//'runtimes' => 'gears,flash,silverlight,browserplus,html5',
'url' => $this->createUrl('blob/uploadFilesPlupload'),
//'max_file_size' => str_replace("M", "mb", ini_get('upload_max_filesize')),
'max_file_size' => Yii::app()->params['maxFileSize'],
'chunk_size' => '1mb',
'unique_names' => true,
'filters' => array(
array('title' => Yii::t('app', 'Images files'), 'extensions' => 'jpg,jpeg,gif,png'),
),
'language' => Yii::app()->language,
'max_file_number' => 1,
'autostart' => true,
'jquery_ui' => false,
'reset_after_upload' => true,
),
'callbacks' => array(
'FileUploaded' => 'function(up,file,response){console.log(response.response);}',
),
'id' => 'uploader'
));
And here's an example of the controller action, supporting chunked upload, adapted from upload.php example in the original Plupload package:
public function actionUploadFilesPlupload()
{
// HTTP headers for no cache etc
header('Content-type: text/plain; charset=UTF-8');
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");
// Settings
$targetDir = sys_get_temp_dir() . DIRECTORY_SEPARATOR . "plupload";
$cleanupTargetDir = false; // Remove old files

// 5 minutes execution time
@set_time_limit(5 * 60);

// Get parameters
$chunk = isset($_REQUEST["chunk"]) ? $_REQUEST["chunk"] : 0;

if (preg_match('/\\.tmp$/', $file) && (filemtime($filePath) < time() - $maxFileAge))

} else
throw new CHttpException (500, Yii::t('app', "Can't open output stream."));
}
// After last chunk is received, process the file
$ret = array('result' => '1');
if (intval($chunk) + 1 >= intval($chunks)) {
$originalname = $fileName;
if (isset($_SERVER['HTTP_CONTENT_DISPOSITION'])) {
$arr = array();
preg_match('@^attachment; filename="([^"]+)"@',$_SERVER['HTTP_CONTENT_DISPOSITION'],$arr);
if (isset($arr[1]))
$originalname = $arr[1];
}
// **********************************************************************************************
// Do whatever you need with the uploaded file, which has $originalname as the original file name
// and is located at $targetDir . DIRECTORY_SEPARATOR . $fileName
// **********************************************************************************************
}
// Return response
die(json_encode($ret));
