html - PHP zip file upload does not work -

my html form:

<form action='' method="post" enctype="multipart/form-data"> <input type="file" name="file" id="file"> <input type="submit" name="submit" value="submit"> </form> 

my php file:

if ($_post['submit'] == "submit") {             echo "upload: " . $_files["file"]["name"] . "<br>";             echo "type: " . $_files["file"]["type"] . "<br>";             echo "size: " . ($_files["file"]["size"] / 1024) . " kb<br>";             echo "temp file: " . $_files["file"]["tmp_name"] . "<br>";             if (file_exists("/downloads/" . $_files["file"]["name"]))             {                 echo $_files["file"]["name"] . " exists. ";             }             else             {                 move_uploaded_file($_files["file"]["tmp_name"],                 "/downloads/" . $_files["file"]["name"]);                 echo "stored in: " . "/downloads/" . $_files["file"]["name"];             } } 

there 2 folders in public_html: tmp , downloads, both 777 permissions (just test)

this file located in .htaccess protected folder within downloads (public_html/downloads/new/update.php) , want zip files uploaded in downloads dir.

this code won't give me errors, not upload file. why?

try adding

if(move_uploaded_file(...)){  echo "it works"; } else {  echo "nope"; } 

and replace:

 move_uploaded_file($_files["file"]["tmp_name"], "/downloads/" . $_files["file"]["name"]); 

with:

 move_uploaded_file($_server['document_root'].'/'.$_files["file"]["tmp_name"], $_server['document_root']."/downloads/" . $_files["file"]["name"]);
