Download File in Yii

问题:

I am trying to write a script in Yii for downloading files from the server.

The files are located in webroot of the Yii project,

but I got every time file not exist error, could anyone see where is wrong:

public function actionDownload($id) {
    $audio = Audio::model()->findByPk($id);
    $file =  Yii::getPathOfAlias('webroot') . $audio->path;
    if (file_exists($file)) {
        header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
        header('Content-Description: File Transfer');
        header('Content-Type: application/octet-stream');
        header('Content-Disposition: attachment; filename=' . $audio->path);
        header('Content-Length: ' . filesize($audio->path));
        $audio->downloaded = $audio->downloaded + 1;
        $audio->save();
    }else{
        echo "file not exist: ".$file;            
    }
    exit;
}

error I got is:

file not exist: /var/www/vhosts/ikhwanbiz.org/httpdocs/userfiles/reklames/media/deneme/sen%20dep%20olmisem.mp3

Thanks

Bili, this works well for me and seem to be fine on most browsers.

$filename = 'your_file_name.csv';
header('Content-Disposition: attachment; charset=UTF-8; filename="'.$filename.'"');
$utf8_content = mb_convert_encoding($content, "SJIS", "UTF-8");
echo $utf8_content;
Yii::app()->end();
return;

Hope it helps, good luck!

It looks like the filename portion $audio->path is URL-encoded, while the name of the actual file on the server is not. You should fix it at the source (no idea where that path is set from), but in the meantime an easy workaround would be to write

$file =  Yii::getPathOfAlias('webroot') . urldecode($audio->path);

This is more of a php question than a yii one.

for eg,

<?php
header("Content-disposition: attachment; filename=huge_document.pdf");
header("Content-type: application/pdf");
readfile("huge_document.pdf");
?>
