People hate waiting unsure of if their upload >is actually working. Anyone think they can add this??? I don`t think the protocol itself (HTTP) makes it possible. I guess this is up to the browser, since the browser is the one doing the sending.
	Wang DaQing wrote : 183 I have changed the copy file part from: for($i=1; $i<=UPLOAD_SLOTS; $i++) { if(${"infile".$i}!="none" && copy(${"infile".$i}, INCOMING.${"infile".$i."_name"}) && unlink(${"infile".$i})) { echo ${"infile".$i."_name"}." uploaded<br>"; } } to use move method. I think it will get better performance. But I don`t know will it work ok on all platform. for($i=1; $i<=UPLOAD_SLOTS; $i++) { if(${"infile".$i}!="none") { $dstname = INCOMING.${"infile".$i."_name"}; if(file_exists($dstname)) unlink($dstname); if( rename(${"infile".$i},$dstname) ) echo ${"infile".$i."_name"}." uploaded<br>"; } }

	JD Daniels wrote : 541 RE: Durieu Fabrice Question, The Problem is not with any code, It is with PHP configuration.... Open the php.ini and change upload_max_filesize = 2M to however large of files you need. PHP defaults to only 2mb. (remember to restart apache after you are done) If you don`t have access to php.ini, put a .htaccess file in your scripts directory with this line: php max_upload_size = 10mb (or whatever you need) Note:- I may have the syntax for the .htaccess a little screwed.. I haven`t actually had to use it yet :)
