I'm using a php video web script which includes this buy_video.php file, which calculates the video uploader's earned amount, and insert's that amount in the 'u_paid_videos' table column named 'earned_amount', which appears in this file on line 73:

<?php
ob_start();

if (IS_LOGGED == false) {
    $data = array('status' => 400, 'error' => 'Not logged in');
    echo json_encode($data);
    exit();
}

if (!empty($_POST['id'])) {

    if (!is_array($_POST['id'])) {
        $id_array[] = $_POST['id'];
    } else {
        $id_array = $_POST['id'];
 	}

	// get cost video
	// get the default video price, to use if there is no per video play price
	$db->where('name', 'video_play_price');
	$db_cost = $db->getOne('config');
	$video_cost = (float)$db_cost->value;

	// the number of submitted videos - used to determine if all records were inserted
	$count_video = count($id_array);
	$user_id = $user->id;

	$wallet = (float)str_replace(',', '', $user->wallet);
	$balance = (float)str_replace(',', '', $user->balance);

	// add up the video prices
	$amount = 0;
	foreach ($id_array as $id) {

		$video_id = (int)PT_Secure($id);

		// get video data
		$video = $db->where('id', $id)->getOne(T_VIDEOS);
		// add the video play price if any, or the default price
		$amount += $video->video_play_price?$video->video_play_price:$video_cost;
	}

	// determine if the user has enough credits
	if( ($wallet >= $amount) OR ($balance + $wallet >= $amount) ) {
	//if( ($wallet >= $amount) OR ($balance >= $amount) ) {

		$db->startTransaction();

		$inserted_records = 0;
		foreach ($id_array as $id){

			$video_id = (int)PT_Secure($id);

			// get video data
			$video = $db->where('id', $id)->getOne(T_VIDEOS);

			// use the video play price if any, or the default price
			$video_cost_new = $video->video_play_price?$video->video_play_price:$video_cost;

			// credit the user 50% of the video cost
			$uploader_amount = $video_cost_new *0.50;



			// add data to paid table
			$insert_buy = $db->insert('u_paid_videos', [
				'id_user' => $user_id,
				'id_video' => $video_id,
				'session_key' => $_SESSION['session_key'],
				'video_play_price' => (string)$video_cost, // the cost at the time of purchase // this is the default video cost not the $video_cost_new
				'video_title' => $video->title, // storing the title
				'user_id_uploaded' => $video->user_id, // the user who uploaded the video
				'earned_amount' => $uploader_amount,
				]);

			// count successful inserted records
			if ($insert_buy) {
				$inserted_records++;
			}

			//update the 'balance' of the user who uploaded the video
			// get the user's record
			$userwallet = $db->where('id', $video->user_id)->getOne(T_USERS);

			// add to the balance
			$videouserwallet = $userwallet->balance+$uploader_amount;

			// update the record
			$db->where('id', $video->user_id);
			$update_balance = $db->update(T_USERS, [
				'balance' => number_format($videouserwallet, 1, '.', ''),
			]);
		}

		$update_wallet = null;
		$update_user_balance = null;


ETC .....................................................

Ultimately, I’m trying to integrate the buy_video.php file’s ‘$earned_amount’ into a web script’s existing transaction file.

Here are a couple of lines from that transaction file:

$this_day_video_earn = $db->rawQuery("SELECT SUM(amount - admin_com) AS sum FROM ".T_VIDEOS_TRSNS." c WHERE `time` >= ".$day_start." AND `time` <= ".$day_end." AND user_id = ".$pt->user->id);
$today_earn = $this_day_ads_earn[0]->sum + $this_day_video_earn[0]->sum ;

and

$trans = $db->where('user_id',$user->id)->orderBy('id','DESC')->get(T_VIDEOS_TRSNS);

That may not be enough info, but I’d like assistance changing those lines to:

$this_day_video_earn = $db->rawQuery("SELECT SUM(earned_amount) AS sum FROM “.T_VIDEOS.” c WHERE time >= “.$day_start.” AND time <= “.$day_end.” AND user_id = ".$pt->user->id);
  
  
  $trans        = $db->where('user_id',$user->id)->orderBy('id','DESC')->get(T_VIDEOS);

I tried those changes without success.
Any guidance/suggestions will be appreciated.

Im not much of a coder, and I obviously did this wrong since it is not working. Im trying to bring a new field value in to an existing php file. I created a new table, and an admin page to control that field. I cant, however, figure out how to use that value in a different php file. Actually, there are 2 files. Each using a different field from that new table. I will post what my current code is below with the additions I tried to add. I bolded the lines that contain the tags Im trying to use. Any and help you can give in fixing this to make it work is greatly appreciated.

Hello!

I'm making a interface in a website do manage files in a ftp hosted on other server.

I'm using the function ftp_get() to download a file but I've tried different aways but I dosent seem do be able to download the file directly from the FTP server do the user the only way it works is if I download the file to the website server first then to the client.

Is there any way that I can download the file directly to the user without have to hosting it permanently on the website server?

Thank you

I've written the following code:

Code: [Select]
<?php
echo '<img src="Sheph.png" />';


function Wad(){
if (file_exists("Sheph.png")) {
    header('Content-Description: File Transfer');
    header('Content-Type: application/octet-stream');
    header('Content-Disposition: attachment; filename='.basename("Sheph.png"));
    header('Content-Transfer-Encoding: binary');
    header('Expires: 0');
    header('Cache-Control: must-revalidate');
    header('Pragma: public');
    header('Content-Length: ' . filesize("Sheph.png"));
    ob_clean();
    flush();
    readfile("Sheph.png");
    exit;
}
}
Wad();
?>
What I want to do is show the image AND show a file download window.
The problem is that it shows the download window but the image doesn't appear. and if I comment the function and keep the echo part only,the image appears normally.

What's wrong ? 

Hi all,

I'm trying to make a PHP script that downloads a file off a remote FTP server and serves the file to the visitor with a limited download speed.

Right now I'm using fopen() like this:

Code: [Select]
$path = "ftp://".$username.":".$password."@".$server."/";
$fullPath = ($path.$fileName);

$speed = 400; // 400 kb/s download rate

    header("Cache-control: private");
    header("Content-Type: application/octet-stream");
    //header("Content-Length: ".filesize($fullPath));
    header("Content-Disposition: filename=\"".$fileName."\"");

    flush();

   $fd = fopen($fullPath, "r");
   while(!feof($fd)) {
         echo fread($fd, round($speed*1024));
       flush();
       sleep(1);
   }
   fclose ($fd);


The file does download but with the wrong speed (8kb/s), does anyone know why?

When I run the same code with a local file instead of a file on FTP it works fine and downloads at the speed I set it to..

Thanks

I'm wanting to have users able to download a file, but I'm wanting it to be a file that only users who are logged in can download. Basically, I don't want a user to be able to enter the URL and download it while not being logged in. Does anyone know what I would use to do this? Thanks.

The other day I noticed someone had post something like this, well this was actually the solution to the problem. But it got me thinking about a project of mine that I am working on and the need to pump out a downloadable file. We are storing most of the files in a database using base64 encoding the 2 key types of files we are storing are images and PDF's mostly pdf's anyway where I am wanting to go with this is, is there anyway to take the base64 encoded file and get it to download through this, or am I tackling the idea in the wrong way?

<?php
$filename = 'somename.txt'; //this would obviously be changed according to the file type we would output

$data =<<<DATA
I know my data would go here for the given file once decoded.
DATA;

header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename=' . $filename);
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . strlen($data));
echo $data;
?>

Hiya guys

After getting everything else working how I expected, I'm sort of struggling on the last step. Downloading

I have an upload.php file that allows me to upload a file to Mysql, the fields available a

upid - Primary
id - Need to link this to the logged on user id name
type
size content   The upload works perfectly

Can anyone help with implmenting it to the profile.php (1st page after login)

On profile page I have:

Welcome "username" from Session
Dynamic Table display his user id, username and password at the moment, this will be changed as not needed tho. I am using the sessions MM_Username to pass from the login

The table for Login looks like:

id - primary username password

I assume that if I can copy the ID from login and put it in ID in Upload and add colums to dynamic table to show the upload file, will this make that file only available to logged in user?

Cheers

On PHP 5.2.14.

I want to make files downloadable from my website. This seems easy enough:
<?php
$file = "downloads/someFile.txt";
// Set headers
header( "Content-Description: File Transfer" );
header( "Content-Type: application/force-download");
header( "Content-Length: " . filesize( $filename ) );
header( "Content-Disposition: attachment; filename=$file");
// header( "Content-Transfer-Encoding: binary");
readfile( $file );
unlink( $file );
?>
You'll notice, however, that I have "unlink" at the end of this file. That's exactly what I want: to remove the file from the server once it has been downloaded, to prevent anyone else from downloading it.

Here's the conundrum: When the user navigates to this URL, browsers offer the choice of Open/Save/Cancel. I don't want users to "open", and if the user presses "cancel", well then I probably don't really want the file deleted.

In short: I want the file SAVED, only. And I want to delete the file immediately after it has been downloaded.

Thoughts?

Hi PHP freaks!!   I have manage to make a script to upload file in database and its working. I will share to you the codes so for other viewers and readers to use also.

if($result){
			if($_FILES['LRCard']['name'] != ""){
				$filename = $_FILES['LRCard']['name'];
				$ext = strrchr($filename,".");
				$LRCardname = $student_id;
				$LRCardname .="_". $filename; 
				if($ext ==".jpg" || $ext ==".jpeg" || $ext ==".JPG" || $ext ==".JPEG" || $ext ==".gif" || $ext ==".GIF"){
					$size = $_FILES['LRCard']['size'];
					if($size > 0 && $size < 5000000){
						$archive_dir = "LRCards";
						$userfile_tmp_name = $_FILES['LRCard']['tmp_name'];
						if(move_uploaded_file($userfile_tmp_name, "$archive_dir/$LRCardname")){
							/*
								if LRC is successfully uploaded then LRC is stored in database.
							*/
							mysql_query("update student_information set LRCard='$LRCardname' where student_id='$student_id'", $link_id); 
							$flag = "success"; 
							if(mysql_error()!=null){
								die(mysql_error());
							}

						}
						else{
							if(file_exists('LRCard/' . $LRCardname)) {
								unlink('LRCards/' . $LRCardname); 
							}
							rollbackData();
						}
					}
					else{
						if(file_exists('LRCards/' . $LRCardname)) {
							unlink('LRCard/' . $LRCardname); 
						}
						rollbackData();
						die("You can upload LRCard of 5 MB size only. Please, try again.");
					}
				}
				else{
					if(file_exists('LRCards/' . $LRCardname)) {
						unlink('LRCards/' . $LRCardname); 
					}
					rollbackData();
					die("You can upload LRCard of .jpg, .jpeg, .gif extensions only. Please, try again. ");
				}
			} 	
		}
		else{
			$flag="error";
		}
		if($flag == "success"){
			mysql_query(" COMMIT ");
			$flag="success";
			if(mysql_error() != null){
				die(mysql_error());
			}
	    }

Now, my problem is how to make a Php script to DOWNLOAD this uploaded file considering the 1. file path 2. file name 3. file extension. 4. student_id (to determine the specific file from a specific student)   My plan is to make a download button which hyperlink to download.php and after clicking that button the specified file to a specific student id will automatically be downloaded by the browser.  

The following code works fine when using chrome or firefox, but fails with IE.
Error: Requested site is either unavailable or cannot be found.

Question: Does anyone see anything here that is a known bug with IE that I don't know about?

Code: [Select]
public function download(){
if($this->validateFile()){
if(!headers_sent()){
header('Content-type: '.$this->getType());
header('Content-Disposition: attachment; filename="'.$this->name.'"');
readfile($this->file);
} else{
echo 'Headers have already been sent and are preventing the file download from taking place.';
}
return true;
}
return false;
}

//I felt this function might be relevant to the issue.  I know, it's kind of a ghetto function, I'll improve on it some other time though.

private function getType(){
$types=array( 'txt' => 'text/plain',
'mp3' => 'audio/x-mp3',
'jpg' => 'image/jpeg',
'jpeg' => 'image/jpeg',
'gif' => 'image/gif',
'png' => 'image/png',
'doc' => 'application/msword',
'swf' => 'application/x-shockwave-flash',
'flv' => 'video/flv',
'mpg' => 'video/mpeg',
'mpeg' => 'video/mpeg',
'avi' => 'video/x-msvideo',
'rtf' => 'application/rtf',
'pdf' => 'application/pdf',
'zip' => 'application/zip',
'exe' => 'application/octet-stream',
'xls' => 'application/msexcel',
'xlsxl' => 'application/msexcel');
if(!$types[$this->getExt()]==''){
return $types[$this->getExt()];
}
return 'application/octet-stream';
}

Hi there,

Thank you,

I was able to upload the files to the DB but now am trying to retrieve it from the table but it's not working.   my code below

<?php                              
while($row = mysql_fetch_array($query1))
{
	 (list($id, $name) = mysql_fetch_array($query1));


echo"<tr>";
    
    echo"<td>&nbsp;$row[category]</td>";                
    echo"<td>&nbsp;$row[description]</td>"; 
	 echo"<td>&nbsp;$row[amount]</td>";
	 	?>
    <td> <a href="approved_req.php?id=<?php echo urlencode($id);?>"
><?php echo urlencode($name);?></a> </td>
<?php
	echo"<td>&nbsp;$row[status]</td>"; 
	?>
    <td><a class="btn btn-success" <?php echo"  href='invoice.php?id=$row[id]'> Pay </a></td>";?></a>
    
    
	  
  
     <?php  
    echo"</tr>";
}
  // }
   ?>
  </table>
  
   <?php 
if(isset($_GET['id'])) 
{
// if id is set then get the file with the id from database
//$con = mysql_connect('localhost', 'root', '') or die(mysql_error());
//$db = mysql_select_db('test', $con);
$id    = $_GET['id'];
$query = "SELECT name, type, size, content " .
         "FROM requisition WHERE id = '$id'";
$result = mysql_query($query) or die('Error, query failed');
list($name, $type, $size, $content) = mysql_fetch_array($result);
header("Content-length: $size");
header("Content-type: $type");
header("Content-Disposition: attachment; filename=$name");
ob_clean();
flush();
echo $content;
mysql_close();
exit;
}
?>  
 

Thanks in advance
