Script pentru upload-ul de fisiere (PHP)

Pana la urma i-am dat de cap:

<?
//Conditia ca fisierul sa fie selectat
if ($_FILES["fisier"]["error"] > 0)
   {
   echo "Trebuie sa selectezi un fisier";
   }
//Conditia ca fisierul sa nu depaseasca o anumita marime:
elseif ($_FILES["fisier"]["size"] > 350000)
   {
   echo "Fisierul este prea mare";
   }
//Conditia ca fisierul sa fie doar srt:
elseif ($_FILES["fisier"]["type"] !== "application/x-subrip")
   {
   echo "Poti incarca doar fisiere de tip .srt";
   }
  
//Verificam daca fisierul exista deja pe server	   
elseif (file_exists("/home/abcdownl/public_html/roedu/files/" . $_FILES["fisier"]["name"]))
   {
   echo "Fisierul pe care incerci sa-l uploadezi exista deja";
   }
  
//Daca totul este okay incercam sa incarcam fisierul
   else
   {
   {
   if (move_uploaded_file($_FILES["fisier"]["tmp_name"], "/home/abcdownl/public_html/roedu/files/".$_FILES["fisier"]["name"]));  // se muta fisierul din directorul temporar al serverului in directorul final
   }
   {
   echo "Fisierul a fost incarcat cu succes.";
   }
   }
?>

Daca cineva modifica executabilul (.exe) in (.jpeg) cum il opresti?Cam vechi postul dar nu are rost sa deschid altul.
Fisier.exe.jpg sau Fisier.exe.jpg.jpg.jpg.jpg

if($type=='application/octet-stream'){
die("Nu acceptam decat poze!");}
if($type=='application/x-msdos-program'){
die("Nu acceptam decat poze!");}

if($size>1000000){
echo "Nu acceptam poze mai mari de 1 mb";
} else{
	 if(($type=="image/jpeg")||($type=="image/jpg")||($type=="image/gif")||($type=="image/png")||($type=="image/bmp")||($type=="image/tif")){
	
move_uploaded_file($temp,$path);}else{ die ("Nu acceptam decat poze"); }

este insuficient

si ce te doare ca e exe.jpg? in fond o sa-l trateze ca jpg, deci o sa dea eroare de header atunci cand omul incearca sa deschida fisierul.

//================================================================================
* Frequently Asked Questions
//================================================================================
:- Q1: I always get an error that the files were not uploaded. IE: GENERAL ERROR
:-  1) Make sure you have CHMOD your "uploads" folder to 777 using your FTP client or similar. If you do
:-    not know how to do this ask your hosting provider.
:-  2) Make sure the uploads folder actually exists. This is the second most common mistake aside from
:-    improper permissions.
:-  3) If you are having problems uploading after you have chmod the uploads folder 777, try using the
:-    full server path in $fullpath below. If you do not know this ask your host.
:-  4) Make sure "file_uploads" is set to ON in php.ini
:-
:- Q2: The page takes long to load and then gives me a page cannot be displayed or a blank page.
:-  1) This is usually due to a low value in php.ini for "max_execution_time".
:-  2) A newer ini setting "max_file_uploads" in php 5.2.12 was added which may be limiting the number
   of simultaneous uploads.
:-  3) Your "upload_max_filesize" and "post_max_size" in php.ini might be set to low.
:-
:- Q3: How do I edit the colors of the form?
:-  1) You will need to edit the CSS near the bottom of the script to change the looks and colors of the form.
:-   Check http://www.w3schools...css/default.asp for more information on CSS.
:-
:- Q4: Can I remove your copyright link?
:-  1) I can't physically stop you. However, I really appreciate it when people leave it intact.
:-   Some people donate $5, $10, $20 to take it off.
:-
:- Q5: You never respond to my emails or to my questions in your forums!
:-  1) I'm a very busy guy. I'm out of town a lot, and at any given time I have several projects going on.
:-   I get a lot of emails about this script, not to mention my other ones.
:-  2) I only understand English. If your English is very bad please write in your native language and then
:-   translate it to English using <http://babelfish.alt.../babelfish/tr>.
:-  3) If you are going to contact me, describe the issue you are having as completly as possible.
:-   "dude me form don't work see it at blah.com what's wrong??!?!" will get no response, ever. Write
:-   in detail what the problem is. Spend a minute on it, and maybe I'll take some of my time to reply.

Cine ami zice si mie unde trebuie sa modific sa ma lase sa  uplodez fisiere  mai mari  macar de 500 Mb  va rog frumos

In legatura cu prima postare din acest subiect:
In fisierul php vreau sa am si partea celui html. Stiu sa includ codul cu echo, dar ce scriu la "action=..." de la form ca sa apeleze functia corect ?

Ai explicat destul de bine, va urma sa dezvolt eu un astfel de script, iar cel mai probabil voi posta free, depinde ce imi mai trece prin minte pana la acel moment.

Am modificat un pic scriptul de la inceputul topicului si acuma pot selecta mai multe fisiere pentru upload.

<form action="upload.php" method="post" enctype="multipart/form-data" name="upload" id="upload">
<input type="file" name="fisier" multiple="multiple" />
<br />
<input type="submit" name="upload" value="Uploadeaza" />
  <input type="reset" name="resetare" value="Reseteaza" />
</form>


In fisierul php, tot din acest topic nu am stiut sa modific a.i. sa si uploadeze cele 3-4 fisiere selectate mai sus.

<?
if ($_FILES["fisier"]["error"] > 0)
  {
echo "A intervenit o eroare: " . $_FILES["fisier"]["error"] . "<br />";
}
else
{
if (file_exists("director/" . $_FILES["fisier"]["name"]))  // verificam daca fisierul exista deja pe server
{
  echo "Fisierul pe care incerci sa-l uploadezi exista deja";
   }
else
{
move_uploaded_file($_FILES["fisier"]["tmp_name"], "director/".$_FILES["fisier"]["name"]);  // se muta fisierul din directorul temporar al serverului in directorul final
{
  echo "ok!";
   }
}
}
?>

Ma puteti ajuta? Mersi.

De fapt cred nu le muta din tmp in director.

Am si eu o problema cu un form de upload. nu imi incarca fisiere mai mari de 1Mb, cele sub 1 Mb le incarca, cele mai mari nu le incarca, nu am restrictie de marime ... de ce ?
