Hello everyone,
I have a question. How could I create a php script that when a user logs in, it will log them into a password protected directory and let them view the files. I want to use this as a upload kind of thing, so the user can upload files and delete files, but they're all on the user's personal directory that is password protected. Please help me with this :) Thanks in advance!
it might be simpler to use an htaccess file (or its equivalent) to password protect anything effectively, and then use php and a database to keep track of and manage their files. you could look into how to do that with htaccess here.
okay, I now know how to create the .htaccess file, but how could i have a php script that will create a directory, and write the username and password in .htpasswd file and set the path in the .htaccess file. Thanks for the help!
you can use the crypt() function to create password hashes for use in the htpasswd file:
the mkdir() function for making a directory:PHP Code:<?php
// Set the password
$password = 'mypassword';
// Get the hash, letting the salt be automatically generated
$hash = crypt($password);
?>
and the fopen/fwrite functions to append a file:PHP Code:<?php
mkdir("/path/to/my/dir", 0700);
?>
all the examples are from php.net, though the last is changed slightly to reflect the format that an htpasswd file would have.PHP Code:<?php
$filename = '.htpasswd';
$somecontent = "$username:$password_hash\n";
// Let's make sure the file exists and is writable first.
if (is_writable($filename)) {
// In our example we're opening $filename in append mode.
// The file pointer is at the bottom of the file hence
// that's where $somecontent will go when we fwrite() it.
if (!$handle = fopen($filename, 'a')) {
echo "Cannot open file ($filename)";
exit;
}
// Write $somecontent to our opened file.
if (fwrite($handle, $somecontent) === FALSE) {
echo "Cannot write to file ($filename)";
exit;
}
echo "Success, wrote ($somecontent) to file ($filename)";
fclose($handle);
} else {
echo "The file $filename is not writable";
}
?>
Here's some code that I was experimenting around with. For some reason, it won't work. Can someone please help me out?
And remember, I am completely new to php, so this is a pretty basic question :)Code:<?php
$password = password;
$hash = crypt($password);
function click_crypt() {
print $hash;
}
?>
<input type="text" name="password">
<input type="submit" name="submit" value="Crypt" onclick="click_crypt()">
um.. because that's not how PHP works. PHP is not like javascript -- it cannot manipulate a page that has already been submitted to a browser. its syntax is similar because they're both based off of C (which is what may have confused you?). you would need to post that form to another script. an example follows:
this is your form (form.html?):
this is your script (crypt.php):PHP Code:<form action="crypt.php" method="post">
<input type="text" name="password" />
<input type="submit" value="Encrypt" />
</form>
you can also combine this form and the crypt.php code into the same script if you'd like (but make sure you are still pointing the <form> to the name of the script, in this case -- crypt.php).PHP Code:<?php
if($_SERVER['REQUEST_METHOD'] == "POST"){
$password = crypt($_POST['password']);
echo $password . " is your encrypted password.";
}
?>
