simple upload (w/ pass protection)
|
 |
Okay.. i know this guy... that had an upload script that had a password protection... and i asked him for the script.. and he wouldn't release it... so recently i remembered about it.. and decided..to attempt to make one... I was talking with Chris and he he gave me permission to mess with it.. (He actually said, "Kurisu says: you could do whatever you want with it. Kurisu says: its free code.) So i was looking around and found a normal upload script and took the $name part of the simple login script and put them together..
Here is the script.. [name this upload.php (or w/e)
PHP Code:
<?php
session_start();
$pass[] = "123456";
#create an array of passwords
#add as many as you want
#used for the logout link, changes the session 'loggedin' = false if ?action=logout
if($_GET['action'] == "logout"){
$_SESSION['loggedin'] = false;
$_SESSION['username'] = "";
}
if($_SESSION['loggedin'] == false){ #checks if the user isnt logged in
if(!$_POST['s1']){ #checks if the form has been submitted, if not show it
}else{
#username check
$tmppass = $_POST['pass']; #the password the user has submitted
$t = count($pass); #count the total passwords
$i = 0;
#create a loop to go through each password and compare it with the name pass which was submitted
while($i <= $t){
if($tmppass !== ""){
if($tmppass == $pass[$i]){
$_SESSION['loggedin'] = true;
header('Location: ?'); #reload the page
}
}
$i++;
}
echo "Invalid password 0.o"; #show an error message if the user enters an incorrect pass
}
die;
}
?>
<?php
$target = "upload/";
$target = $target . basename( $_FILES['uploaded']['name']) ;
$ok=1;
//This is our size condition
if ($uploaded_size > 350000000)
{
echo "Your file is too large.<br>";
$ok=0;
}
//This is our limit file type condition
if ($uploaded_type =="text/php")
{
echo "No PHP files<br>";
$ok=0;
}
//Here we check that $ok was not set to 0 by an error
if ($ok==0)
{
Echo "Sorry your file was not uploaded";
}
//If everything is ok we try to upload it
else
{
if(move_uploaded_file($_FILES['uploaded']['tmp_name'], $target))
{
echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded";
}
else
{
echo "Sorry, there was a problem uploading your file.";
}
}
?>
Then what you wanna do is.. add this script to a page and change the path to the script above...
ALSO-- if you would like to upload files of bigger size change the number found here
PHP Code:
if ($uploaded_size > 350000000)
Code:
<form enctype="multipart/form-data" action="upload.php" method="POST">
<input name="uploaded" type="file" size="30">
<br><br>
<input type="password" name="pass" size="32">
<input type=submit name="s1" value="Upload">
</form>
to change the size of the text area things mess with the numbers inside size="" [of course the higher the bigger]
----
If you would like this with out the password feature.. go back to PHP Tutorials and look for the post called Simple Upload Form
