参数传送到视图问题

本帖最后由 yyszj0911 于 2011-11-24 14:43:05 编辑 代码如下(传不到视图页) ,但是用预设的$file="/var/www/test11.txt";的话就能够传的到 这是怎么回事阿
controller:
function indexAction()<br />
    {<br />
		$file_dir = @$_POST["dir"]; //文件路径为当前目录	<br />
		$file_name = @$_POST["file_name"]; //文件名<br />
		$file=$file_dir.$file_name;<br />
		//$file="/var/www/test11.txt";<br />
		$this->view->downfile = $file;<br />
		echo $this->view->render('download/download.phtml');<br />
    }<br />
Copy after login

view:
$file = $this->downfile;<br />
<br />
if (file_exists($file)) {<br />
    header('Content-Description: File Transfer');<br />
    header('Content-Type: application/octet-stream');<br />
    header('Content-Disposition: attachment; filename='.basename($file));<br />
    header('Content-Transfer-Encoding: binary');<br />
    header('Expires: 0');<br />
    header('Cache-Control: must-revalidate, post-check=0, pre-check=0');<br />
    header('Pragma: public');<br />
    header('Content-Length: ' . filesize($file));<br />
    ob_clean();<br />
    flush();<br />
    readfile($file);<br />
    exit;<br />
}<br />
//$file = $this->downfile;<br />
else{echo $file.'ssa';}
Copy after login



------解决方案--------------------
值是怎么post过来的呢?
------解决方案--------------------
预设的 $file="/var/www/test11.txt"; 显然是绝对路径,这自然没有问题

 $file=$file_dir.$file_name; 
如果也是绝对路径的话应该是没有问题的
如果是相对路径的话,那就要看是否正确了。至少要知道他相对于谁
