PHP - Login Into Site & Download A File
I am a newbie. I need some guidance for logging onto an existing site, and downloading files.
Some tips what I should be looking for? Thanks. Similar TutorialsIs thier some code I can use to Notifiy me of files that are downloaded from my site. I would like to put some public files (PDF) in a folder to where the public could download what ever, but I want to know who downloaded these files. Dont know much more than that just got the idea from another site cause they new I downloaded a file and I thought it would be a good idea on may site to do something like that. I have a site where I want another user that has a password fills out a form & it then downloads to my server. I want them to be able to then download that file from my site at the same time the form is submitted. I've tried adding this code to the bottom of the php file that the form points to but it just displays the file on the screen instead of downloading to the user's computer.
<?php
$file = '/site/downloadfile';
if (file_exists($file)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="'.basename($file).'"');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
readfile($file);
exit;
}
?>
if I put the same code in a separate file it works perfectly but i don't want to add another file if i can help it. Any help appreciated
Hello I already know this is possible with php <?php $file = 'monkey.gif'; if (file_exists($file)) { header('Content-Description: File Transfer'); header('Content-Type: application/octet-stream'); header('Content-Disposition: attachment; filename='.basename($file)); header('Content-Transfer-Encoding: binary'); header('Expires: 0'); header('Cache-Control: must-revalidate, post-check=0, pre-check=0'); header('Pragma: public'); header('Content-Length: ' . filesize($file)); ob_clean(); flush(); readfile($file); exit; } ?> But I am wondering is it possible to just send over a string of data stored in like $data and create a file clientside (nothing server side). So i'm guessing readfile() has to be replaced with something Dear PHPFreak members, I have been searching a solution for serving a file download via my website. The file to be downloaded is actually on a remote server. What i need is a code that serves as a download medium without actually downloading the file to my web server. Something like masking file url Can anyone help me with it ??? Have been trying this since days. But no solution till date. Hi, how much bandwidth is used for 1000 downloads per day or for each download? Is it safe to have no download limits? Thanks
I have a download youtube site http://downloadvideoasmp3.com/ I would like to review an tell me what can be done to be improved. 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 Hi there, I have a cronjob for PHP which generates a table with dynamic data and this table is exported to excel when run. When i have one table it downloads one excel file. I want to download multiple excel files using a for loop. Please Help... Any suggestions will be helpful.. Thank you, Regards, Rohit 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. Hello everyone! I'm somewhat of a newb in this so anyways I have this script and I try to force a browser to download a file when someone hits a download button. here is what I'm trying: header('Content-Type: application-download'); header('Content-Disposition: attachment; filename=' .basename($dl_id)); readfile($dl_id); It seems to work in Chrome, Firefox, but it doesn't work in IE Any suggestions? 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 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 $data; ?> I was able to upload the files to the DB but now am trying to retrieve it from the table but it's not working.
my code below
<?php
while($row = mysql_fetch_array($query1))
{
(list($id, $name) = mysql_fetch_array($query1));
echo"<tr>";
echo"<td> $row[category]</td>";
echo"<td> $row[description]</td>";
echo"<td> $row[amount]</td>";
?>
<td> <a href="approved_req.php?id=<?php echo urlencode($id);?>"
><?php echo urlencode($name);?></a> </td>
<?php
echo"<td> $row[status]</td>";
?>
<td><a class="btn btn-success" <?php echo" href='invoice.php?id=$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
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( $file ); ?> You'll notice, however, that I have "unlink" at the end of this file. That's exactly what I want: to remove the file from the server once it has been downloaded, to prevent anyone else from downloading it. Here's the conundrum: When the user navigates to this URL, browsers offer the choice of Open/Save/Cancel. I don't want users to "open", and if the user presses "cancel", well then I probably don't really want the file deleted. In short: I want the file SAVED, only. And I want to delete the file immediately after it has been downloaded. Thoughts? The following code works fine when using chrome or firefox, but fails with IE. Error: Requested site is either unavailable or cannot be found. Question: Does anyone see anything here that is a known bug with IE that I don't know about? Code: [Select] public function download(){ if($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 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.
How can I create a PHP script that will trigger a download?
For example, if I have a database of files and file IDs, and have a hyperlink like this in an HTML page:
getfile.php?FileID=1001
How can I code the getfile.php file so that no matter what type the file is (ZIP, EXE, JPG, AVI, etc), it will cause the browser to prompt the user to download the file?
(Not entirely sure if this is more a PHP question or an HTML question because of how I'm approaching it...)
(The purpose of me using the getfile.php file is so that files can be physically moved around without me having to update all of the hyperlinks in the HTML files, but rather just update the paths in the SQL database instead.)
Edited by cbassett03, 02 September 2014 - 11:25 PM. I have a page in which i upload a circular & also select users who can view this page using multiple select dropdown box. Now how to display the uploaded file to selected users when they login and not to other users. Can anybody help. Thanks in advance. |
