    How to block a video from being accessed via url?

    in PHP Coding Help

    Posted

    I have added this to .htaccess: 

    RewriteCond %{REQUEST_URI} \.(mp4)$ [NC]
RewriteRule ^ validate.php?request_url=%{REQUEST_URI} [L]


    and added a validate.php file, containing this: 

    <?php
$v = $_GET['video'] ?? null;

if(file_exists($v)) {
    unlink($v);
    header('Content-type: application/mp4');
    header('Content-Disposition: inline; filename=video.mp4');
    readfile("./mytestvideo.mp4");
} else
   http_response_code(404);


    to the root directory. And then searched and played a video, but still see the unmasked url/path to the video, instead of this type of url/path:

    http://mymp4.com?validate.php?video=40f677a45113eb829e345d278b8d1d31

    as I was hoping for.

    I'm sure I must have something incomplete.

    Any additional guidance you'd like to share is much appreciated.

    Much thanks again

    Many thanks again for your posting/reply.  I have added this code to an .htaccess file:

    RewriteEngine OnRewriteCond %{REQUEST_URI} \.(mp4)$ [NC]
    RewriteRule ^ validate.php?request_url=%{REQUEST_URI} [L]

    I have added this php file: 

    <?php
$v = $_GET['video'] ?? null;

if(file_exists($v)) {
    unlink($v);
    header('Content-type: application/mp4');
    header('Content-Disposition: inline; filename=video.mp4');    
    readfile("./mytestvideoo.mp4");    
} else
   http_response_code(404);

    named validate.php to the main directory.

    I just don't know what to do with this: 

    //Generate the link

$normalText = "this is just your average string with words and stuff";

$hashedText = md5($normalText);

fopen($hashedTest, 'w');

echo "<a href='validate.php?video={$hashedText}'>Link to the video</a>

    should I put it in a .txt file and add it to my main directory? If so, named what?

    That's just what I'm not clear on before I test all this.

    I look forward to your comments/anything you'd like to share.

    Thanks for your reply.

    Which one would work best for my request: " Is there a way to block or scramble the video's url from being available to be copied? If not, is there a way to have that url be available only if the potential viewer is 'logged-in' to the web site? Or some type of authentication based on checking for a user's PHP temp session file before allowing access from the video's url?"

    How about something like this: 

    RewriteEngine OnRewriteCond %{REQUEST_URI} \.(mp4)$ [NC]
RewriteRule ^ validate.php?request_url=%{REQUEST_URI} [L]
# To disable or prevent the directory access/listing
Options -Indexes

    with this validate.php?: 

    <?phpsession_start();
if (!isset($_SESSION['login'])) {
header ('Location: index.php');
exit();
} else {
// Get server document root
$document_root = $_SERVER['DOCUMENT_ROOT'];
// Get request URL from .htaccess
$request_url = $_GET['request_url'];
// Get file name only
$filename = basename($request_url);
// Set headers
header('Content-type: application/mp4');
header('Content-Disposition: inline; filename='.$filename);
// Output file content
@readfile($document_root.$request_url);
}

    I look forward to any additional guidance/comments/suggestions

    When I play a video (that is blocked from being downloaded as a file from a php web script player that I'm using) I can see the url address of the file from my PC in dev tools > networking > media, Is there a way to block or scramble the video's url from being available to be copied? If not, is there a way to have that url be available only if the potential viewer is 'logged-in' to the web site? Or some type of authentication based on checking for a user's PHP temp session file before allowing access from the video's url?

    Help with checking 'balance' after 'wallet'

    in PHP Coding Help

    Posted

    Hello McGyver,

    I have re-read your great advice (thank you again), regarding the "two tables". I  am trying to understand more clearly what you've advised, and trying to improve what is already there (rather than re-create everything). Would it be possible that you could message me so I might be able to ask you some more specifics directly?

    Thanks again for your kind posting replies. I look forward to your positive response.

    Many thanks again

     

    Help with checking 'balance' after 'wallet'

    Thanks again for your reply.

    Yes, I've been reading. I've been given a lot of advice and tried many things without success (including what was provided here and elsewhere).
    But, some of the explanation I don't understand, like this sentence "use the new wallet and balance amounts in that existing single query, per the comment i added at that point, rather than to start adding more queries before the start of where the transaction/rollback logic starts". 

    Earlier in this thread I was told "Try reading your own code. Go through it line by line and check the value of each variable after each line executes". Based on that, as far as I can see, this should work, but shows 'not enough money:

      

    } else {

//     4    +    4      >=    6
if ($wallet + $balance >= $amount) {

//   8  =               4    +    4
$balance = (string)($balance + $wallet);

//   2   =              8    -    6
$balance = (string)($balance - $amount);
$wallet= '0';

$db->where('id', $user_id);
$update_user_balance = $db->update(T_USERS, [
'balance' => $balance
]);

}
}

     

    any additional guidance is appreciated

     

     

    Help with checking 'balance' after 'wallet'

    Thanks for your reply. 

    This seems to work successfully, where a purchase uses the amount in ‘wallet’ first, and then uses the amount in ‘balance’ if there is not enough in ‘wallet’:

    however, if all videos cost 2 (or higher), and there is “1” left in the ‘wallet’, it will never get used. I am looking to see how I can make more like if ‘wallet’ is zero then deduct from ‘earnings’ (or wallet + balance = amount)…

    I have tried this revision without success: 

    		// Check if user has enough wallet amount to purchase video
		if($wallet >= $amount){

			$wallet = (string)($wallet - $amount);
			$db->where('id', $user_id);
			$update_wallet = $db->update(T_USERS, [
				'wallet' => $wallet
			]);

			} else {

			if($wallet < $amount && $wallet + $balance >= $amount){

			$wallet = (string)($wallet - $amount) + $balance = (string)($balance - $amount);

							$db->where('id', $user_id);
							$update_user_balance = $db->update(T_USERS, [
								'balance' => $balance
								]);
							$db->where('id', $user_id);
							$update_wallet = $db->update(T_USERS, [
							'wallet' => $wallet
							]);
						}
			}

    I’m trying to say this;
    if what’s in the ‘wallet’ is less than the amount AND $balance has more than or equal to the amount: 

    if($wallet < $amount && $wallet + $balance >= $amount){

     

    then proceed to deduct whatever is left in 'wallet' to satisfy the amount + the rest of the amount from $balance: 

    $wallet = (string)($wallet - $amount) + $balance = (string)($balance - $amount);

     

    but, apparently I need to say this better in code:
    “then proceed to deduct whatever is left in 'wallet' to satisfy the amount + the rest of the amount from $balance”

    any additional help is greatly appreciated.

    Thanks for your reply. Much appreciated.

    I have tried your suggestion without success.

    I see a pop-up dialog box  that displays: "Something went wrong. Please try again later!!" (from the script.js file):

      

    function PT_MultipleBuyVideo() {
    var checked = getSelectedVideos();
    if (!checked) { return false; }

    swal({
        title: "",
        type: "info",
        html:"Simply proceed to purchase " + countSelectedVideos() + " video(s) at a total cost of " + countTotalCredits() +" credits",
        showCancelButton: true,
        cancelButtonText: "Close",
        customClass: 'sweetalert-lg',
        confirmButtonText:'Proceed'
    }).then(function(){

        $.ajax({
            url: PT_Ajax_Requests_File() + 'aj/buy-video',
            type: 'POST',
            dataType: 'json',
            data: {id:checked},
        }).done(function(data){
            if (data.status == 200) {
                for (var i = 0; i < checked.length; i++) {
                    var button = $("button[data-action='multiple_select_button'][data-id='" + checked[i] + "']")
                    buttonMultipleSelectingStyle(button, 'purchased');
                }

                swal({
                    title: "Success",
                    type: "success",
                    html:"",
                    showCancelButton: true,
                    cancelButtonText: "Close",
                    customClass: 'sweetalert-lg',
                    confirmButtonText:'Go To Video(s)'
                }).then(function(){
                    window.location.href='/paid-list';
                });

            } else {
                if (data.error_num == 1) {
                    swal(
                        'Error!',
                        'Not enough money(test)',
                        'error'
                    );
                } else {
                    swal(
                        'Error!',
                        'Something went wrong. Please try again later!',
                        'error'
                    );
                }
            }
        }).fail(function() {
            swal(
                'Error!',
                'Something went wrong. Please try again later!!',
                'error'
            );
        })
    });
}

    The only thing that shows 'not enough money' from 'wallet' or "success' (when there is enough) is this: 

    		if($wallet + $balance >= $amount) {
		$wallet = (string)($wallet - $amount);
		 //}elseif    $wallet = 0; {
		$balance = ($balance - $amount);

		$db->startTransaction();

    Any other ideas will be appreciated

    So, I just tried this without success:
     

    Code: 
    	if ($wallet >= $amount) {
		$wallet = (string)($wallet - $amount);
		} elseif ($wallet + $balance >= $amount) {
		$balance = (string)($balance - $amount);
		$db->startTransaction();

etc....

    By ‘without success’, I mean that the same message appears as if just the ‘wallet’ doesn’t have enough “Not Enough Money” - when I test - by having 3 in ‘wallet’ and 3 in earnings (equals a total of 6) but try to purchase something that costs 5.

    Any suggestion, guess or guidance will be appreciated.

    In my account 'wallet' I have 3, and in 'balance' I have 3, which equals a total of 6. I tried to purchase a total of 5, with this code added:  

    if($wallet >= $amout) {
   // take money first from wallet
} elseif ($wallet + $balance >= $amout) {
   // take money first from wallet and/or balance
} else {
		echo json_encode([
			'status' => 400,
			'error_num' => 1,
			'error' => 'Not enough money'
		]);

} else {

    I saw 
    "Something went wrong. Please try again later!!"

     

    any additional help is appreciated

    Thanks for your reply.

    I appreciate your time you've taken to explain. It all makes sense.
    It is  a lot for me to implement, although I'm working on it.

    However, the first step for me, I believe, would be to get help with adding in these things you've commented, please, before I start improving my tables.:
    // it is here that you would include the balance amount
    // you would calculate new wallet and balance amounts
    // you would include the new 'balance' too

    any guidance, examples of what's needed there, will be greatly helpful.
