foxclone

@kicken - I thought the md5sum problem was fixed but it's not. Here's an example of the differences:

md5sum of original foxclone50_amd64.deb file: a00bd61088cf4f4a0138d51f24e554f0

md5sum of downloaded foxclone50_amd64.deb file: 6f23af927c0a3348345ed1415fb89e36

Here's the current code:

<?php

function mydloader($filename=NULL)  {
    if( isset( $filename ) ) {        
        $ext = pathinfo($filename, PATHINFO_EXTENSION);
            {
            if ($ext == '.iso')
                header('Content-Type: application/x-cd-image');
            elseif ($ext =='.gz')
                header('Content-Type: application/zip');
            else
                header('Content-Type: octet-stream'); 
            }
        header('Content-Length: ' .filesize($filename));
        header("Content-Disposition: attachment; filename={$filename}");
        header('Pragma: no-cache');
        header('Expires: 0');        
        readfile($filename);
                  
      }
        
    else {
        echo "isset failed";
        }  
}
mydloader($_GET["f"]);

Thanks for your help.

Thanks to both of you for your replies.

I check the downloaded file's md5sums manually. Users have been complaining.

@kicken - You said the following:

Your formatting needs work.

I know. I just started using VS Code instead of a text editor.

You have a pair of {} that are unnecessary and hard to even see.

I'm not sure where you're talking about

Your if/elseif/else blocks should have {} around them for readability. The way you indented your code makes it look like all your headers are part of the else branch but only one of them actually is.

I'll reformat it

You should add code to disable output buffering or you might hit memory errors on large files.

The largest file is 870Mb and we've had no problems.

You should add a Content-length header so the browser's download progress bar works.

Will do.

-----------------------------------------------------------------------------------------------------

Again, thanks to both of you. I'll post revised code soon.

The I had this problem solved, but it isn't. Still having a problem with downloaded files having the wrong md5sum. I've scrubbed the script again to be sure there aren't any tabs or blank spaces following the commands. Also no php errors. Here's the code.

<?PHP
error_reporting(E_ALL);
ini_set('display_errors', '1');

function mydloader($filename=NULL) {
    if (isset($filename)) {
        $filename = preg_replace("/\s+/u", " ", $filename);  // Make sure no hidden characters in filename
        $ext = pathinfo($filename, PATHINFO_EXTENSION);{  // Get file extension
        if ($ext == '.iso')
            header('Content-Type: application/x-cd-image');
        elseif ($ext == '.gz')
            header('Content-Type: application/zip');
        else
            header('Content-Type: octet-stream');}
            header("Content-Disposition: attachment; filename={$filename}");
            header('Pragma: no-cache');
            header('Expires: 0');
            readfile($filename);
}
       else {
          echo "isset failed";
            }
}
mydloader($_GET["f"]);  // Filename passed from calling script

I'm totally confused as to why this isn't working correctly. I spent the entire weekend trying go get this working so I'd really appreciate some help on this.

The config directory is under the public_html directory as shown in this screenshot.

I'm trying to convert existing website php code to use config.php on my local server but keep getting the following http 500 error before anything shows on the screen:

My config directory is within my project directory until I get this working. Here's the contents of config.php:

I know I must be looking past the problem after looking at the code for several hours, but I'm stumped. I'd appreciate some help on this.

@ginerjm - The problem was with = instead of ==. Thanks a lot!

March 3, 2022

@ginerjm - As I said, that code is working correctly now and does the downloads. The problem now is that the md5sums on the downloaded files is incorrect coming from the server. I removed all the sql code to ensure that it wasn't causing the problem.

What's wrong with the if statements? The structure is right from https://www.php.net .

March 3, 2022

When I run the following code on my local apache server, the md5sums of the downloaded files are correct. When I run the code on my web host, I get different md5sums. I've scrubbed the code to eliminate blank spaces before the readfile statement. I'm not getting any errors with error_reporting(E_ALL), display_errors=On, and output_buffering = off in my local php.ini as well as on my web host.

Here's the code I'm currently using:

<?php
function mydloader($l_filename=NULL){    
    if( isset( $l_filename ) ) {
        $filename = preg_replace("/\s+/u", " ", $l_filename);//Eliminate any hidden characters
        $ext = pathinfo($filename, PATHINFO_EXTENSION);{
        if  ($ext = '.deb')
            header('Content-Type: application/x-debian-package');
        elseif ($ext = '.iso')
            header('Content-Type: application/x-cd-image');
        elseif ($ext = '.gz')
            header('Content-Type: application/zip');
        else
            header('Content-Type: octet-stream');}
            header("Content-Disposition: attachment; filename={$filename}");
            header('Pragma: no-cache');
            header('Expires: 0');        
            readfile($filename);
      }
        
    else {
        echo "isset failed";
        }  
}      
mydloader($_GET["f"]);

I've removed all other code from this script in order to eliminate any other issues. Does anyone have an idea what's going on?

Thanks in advance.

@ginerjm - error_reporting(E_ALL); and ini_set('display_errors', '1'); are already in my php.ini. Do I still need them for debugging?

Posted March 2, 2022 · March 2, 2022

@ginerjm - removing the closing ?> tag didn't help, but thanks for the reminder.

Posted March 2, 2022 · March 2, 2022

@gizmola - I moved all that was in the php directory into a newly created directory called includes. My config.php now looks like this:

<?php

$app_root = DIRNAME(__DIR__);

$php_path = $app_root.'../includes/';

include_once $php_path.'PDO_Connection_Select.php';

My index.php starts like this:

<?php

require('../includes/config.php');

require_once($php_path . 'PDO_Connection_Select.php');

require_once($php_path . 'GetUserIpAddr.php');

$ip = GetUserIpAddr();

if (!$pdo = PDOConnect("foxclone_data")) {

exit;

}

$stmt = $pdo->prepare("INSERT INTO access (address) values (?)");

$stmt->execute([$ip]) ;

?>

<?PHP require_once($php_path . 'header.php'); ?>

Problem is, I'm now getting the following error:

Quote

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

The error log states:

Quote

Invalid command 'RewriteEngine', perhaps misspelled or defined by a module not included in the server configuration, referer: http://foxtest/

Any idea what's going on?

Posted March 2, 2022 · March 2, 2022

@gizmola - re: php directory - That is part of the structure provided by the web host.

I've searched all over the web trying to find a tutorial for building a config.php file without success. Lots of info on using php.ini but nothing specifically about config.php. Can you point me to something that will help me learn how to use it?

Posted March 2, 2022 · March 2, 2022

@gizmola - A question for you. Can I include the file that has your PDO connection script in the config.php? This is what I was thinking:

<?php

$app_root = DIRNAME(__DIR__);

$php_path = $app_root.'../php/';

include_once $php_path.'PDO_Connection_Select.php';

$get_ip = $php_path.'GetUserIpAddr()';

Are the variables declared in config.php available in the file that has the include 'config.php' statement?

Posted March 1, 2022 · March 1, 2022

@gizmola - So, does this look correct for a config.php?

Quote

<?php

$app_root = DIRNAME(__DIR__);

$php_path = $app_root.'../php/';

$connection = $php_path.'PDO_Connection_Select.php';

$get_ip = $php_path.'GetUserIpAddr()';

Posted March 1, 2022 · March 1, 2022

@gizbola - I understand what you're saying. My problem is that in some cases the relative path to the php folder is ../../php and in other cases the path is ../php. That's why I was wondering about using absolute path.

EDIT: I just re-read your last post. I could do $phppath = $app_root . '../php';

Posted March 1, 2022 · March 1, 2022

@gizmola - For example, in config.php, could I replace the relative path with the absolute path?

<?php

$app_root = DIRNAME(__DIR__);

$connection = '/php/PDO_Connection_Select.php';

$get_ip = '/php/GetUserIpAddr()';

Instead of

<?php

$app_root = DIRNAME(__DIR__);

$connection = '../../php/PDO_Connection_Select.php';

$get_ip = '../../php/GetUserIpAddr()';

Posted March 1, 2022 · March 1, 2022

@gizmola - can this be used giving an absolute path rather than a relative path? For example can I use $php_scripts = '/php' rather than $php_scripts = '../../php/';

5 minutes ago, ginerjm said:

Actually neither of those changes should have mattered. It was just the proper way to code (IMHO). There must of been another change too.

HTH! And glad to see my code being used.

Other than moving that block of code, I did nothing else. Your code had served me well, thanks for posting it!

Posted March 1, 2022 · March 1, 2022

Thanks to everyone who responded. Removing blank spaces and moving the db connection code after the headers works on both my server and the web host.

@gizmola - thanks for those links. I'll study them and hopefully, do better coding.

Posted March 1, 2022 · March 1, 2022

Here's the full code, including the reason for the db connection.

<?php

error_reporting(E_ALL);



ini_set('display_errors', '1');

$php_scripts = '../../php/';

require $php_scripts . 'PDO_Connection_Select.php';

require $php_scripts . 'GetUserIpAddr.php';

function mydloader($l_filename=NULL){




$ip = GetUserIpAddr();

if (!$pdo = PDOConnect("foxclone_data"))

{ echo "unable to connect";

exit;

}

if( isset( $l_filename ) ) {



header('Content-Type: octet-stream');

header("Content-Disposition: attachment; filename={$l_filename}");

header('Pragma: no-cache');

header('Expires: 0');

readfile($l_filename);



$ext = pathinfo($l_filename, PATHINFO_EXTENSION);

$stmt = $pdo->prepare("INSERT INTO download (address, filename,ip_address) VALUES (?, ?, inet_aton('$ip'))");

$stmt->execute([$ip, $ext]) ;



$test = $pdo->query("SELECT lookup.id FROM lookup WHERE inet_aton('$ip') >= lookup.ipstart AND inet_aton('$ip') <= lookup.ipend");

$ref = $test->fetchColumn();

$ref = intval($ref);



$stmt = $pdo->prepare("UPDATE download SET lookup_id = '$ref' WHERE address = '$ip'");

$stmt->execute() ;

}

else {

echo "isset failed";

}

}

mydloader($_GET["f"]);

exit;

Here's the code for the db connection:

<?php

function PDOConnect($l_dbname=NULL, $l_msg=null, $l_options=null)  {

if ($l_options == null)

{ // set my default options

// echo "db name is '$l_dbname'";

$l_options = array(PDO::ATTR_EMULATE_PREPARES => false,

PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,

PDO::MYSQL_ATTR_FOUND_ROWS => true,

PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES utf8',

PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC);

}

if ($l_dbname == null)

$host="mysql:host=localhost;charset=utf8";

else

$host="mysql:host=localhost;dbname=$l_dbname;charset=utf8";

$uid = "xxxxxxx";

$pswd = "xxxxxxxxxxx";

try   {

$mysql = new PDO($host, $uid, $pswd, $l_options);

}

catch (PDOException $e)   {

if (strtoupper($l_msg) == "SHOWMSG")

    echo "Fatal Error<br>Failed to connect to mysql via PDO.<br>PDO Error msg is:<br>".$e->getMessage();

else

     echo "Fatal Error<br>Possible bad dbname?<br>Failed to connect to mysql via PDO. Sensitive error msg may be viewed with additional parm to call to

     PDOConnect(dbname,'showmsg')".$e->getMessage();

     return false;

}

if (!$mysql)

    return false;

else // all worked - return handle to pdo connection.

     return $mysql;

}

I'm having a problem with a download script. It runs fine on my local apache server, but when I put it on the my webhost's apache server, it goes crazy. Here's the script:

<?php

$php_scripts = '../../php/';
require $php_scripts . 'PDO_Connection_Select.php';
require $php_scripts . 'GetUserIpAddr.php';
function mydloader($l_filename=NULL){


    $ip = GetUserIpAddr();
       if (!$pdo = PDOConnect("foxclone_data"))
      {    echo "unable to connect";
          exit;
      }
    
    if( isset( $l_filename ) ) {  

        header('Content-Type: octet-stream');
        header("Content-Disposition: attachment; filename={$l_filename}");
        header('Pragma: no-cache');
        header('Expires: 0');        
        readfile($l_filename);

      }
        
    else {
        echo "isset failed";
        }  
}
mydloader($_GET["f"]);
exit;

When I say "it goes crazy", I get errors saying that the header values have already been set by apparently by the PDOConnect. Then it actually reads the file. The files being downloaded are .iso, .deb, and .tar.gz. This isn't a php.ini problem; the files are the same on my local machine and the web host. Here's a screenshot:

Does anyone have any idea why this is happening?

January 22, 2022

Thanks again. I missed the php code surrounding the else. It's all working correctly now.

January 22, 2022

Thanks, Barand. It's working better but now I get both results from the if clause when $chk =1.

<?php if($chk == 0)  ?>
  <div id='showMe'>
   <div class="container">
      <div class="row" style="color:red; padding-top:6rem; text-align:center;">
         <h1>Database Update Failed</h1>
      </div>
   </div>
 </div>  
else 
  <div id='showMe'>
    <div class="container">
      <div class="row" style="color:black; padding-top:6rem; text-align:center;" >
        <h1>Database Update Successful</h1>
      </div>
    </div>
  </div>

January 21, 2022

I need to use a php variable in an if.. else clause outside of the block of php code and can't get it working. The existing code block is below. All help is appreciated.

$chk is the variable from the php block and is numeric.

<?php if($chk == 0) { 
  <div id='showMe'>
   <div class="container">
      <div class="row" style="color:red; padding-top:6rem; text-align:center;">
         <h1>Database Update Failed</h1>
      </div>
   </div>
 </div> }
 
else  { 
<div id='showMe'>
  <div class="container">
      <div class="row" style="padding-top:6rem; text-align:center;" >
        <h1><center>Database Update Successful</center></h1>
      </div>
  </div>
endif
</div>  

 </div>  
   </body>
</html>

Thanks much.

I'm trying to get the filesize() of a file based on a retrieval of filename from the database. The file is located in the download directory and the code calling the function is in the root of the website. Here's the code I've tried:

$test = $pdo->query("SELECT filename FROM files WHERE id =1");
   $isoname = $test->fetchColumn();
   $test = "download/".$isoname;
   $isosize = filesize($test)/1000000;

It always returns zero although is returns the correct filename.

Thanks for any guidance in advance.
