Hi thanks for reading,

 

I have put together a simple article cms script for a client. Via the backend they can type in their article and upload a pdf. The pdf needs to be displayed on the article page. So far I have worked out how to display a list of all the uploaded pdf's on the article page. They need the pdf associated with the article only displayed.

 

I need some help  :'(

 

here is the article page:

 

<?php
include 'library/config.php';
include 'library/opendb.php';

// if no id is specified, list the available articles
if(isset($_GET['id']))
{
$self   = $_SERVER['PHP_SELF'];

$query  = "SELECT id, title FROM courses ORDER BY id";
$result = mysql_query($query) or die('Error : ' . mysql_error()); 

// create the article list 
$content2 =  '<ol>';
while($row = mysql_fetch_array($result, MYSQL_NUM))
{
	list($id, $title) = $row;
	$content2 .= "<li><a href=\"courseinfo.php?id=$id\">$title</a></li>\r\n";
}

$content2 .= '</ol>';

$title   = '<span class="course_grey">our<span class="orange_hed"> courses:</span>';
} 

if(isset($_GET['id']))
{
// get the article info from database
$query   = "SELECT title, content FROM courses WHERE id=".$_GET['id'];
$result  = mysql_query($query) or die('Error : ' . mysql_error()); 
$row     = mysql_fetch_array($result, MYSQL_ASSOC); 

$title   = $row['title'];
$content = $row['content'];
}

I have worked this out

 

if(isset($_GET['id']))
{
// get the article info from database
$query   = "SELECT id, title, content, name, path FROM courses WHERE id=".$_GET['id'];
$result  = mysql_query($query) or die('Error : ' . mysql_error()); 
$row     = mysql_fetch_array($result, MYSQL_ASSOC); 

$title   = $row['title'];
$content = $row['content'];
$pdfname = $row['name'];
$pdfpath = $row['id'];
}

 

<a href="downloadpdf.php?id=<?=$pdfpath;?>"><?=$pdfname;?></a>

 

The only thing I have now found is that when i open the pdf, it says its not supported file type or damaged or wasnt correctly decoded?

 

If i open the file from the server it is fine but if i open it from the webpage it is not?

 

Does anyone know why?

this is my upload script:

 

$uploadDir = '/#/';

if(isset($_POST['save']))
{
$title   = $_POST['title'];
$content = $_POST['content'];

//file upload

$fileName = $_FILES['userfile']['name'];
$tmpName  = $_FILES['userfile']['tmp_name'];
$fileSize = $_FILES['userfile']['size'];
$fileType = $_FILES['userfile']['type'];

    // get the file extension first
$ext      = substr(strrchr($fileName, "."), 1); 

// generate the random file name
$randName = md5(rand() * time());

// and now we have the unique file name for the upload file
    $filePath = $uploadDir . $randName . '.' . $ext;

    // move the files to the specified directory
// if the upload directory is not writable or
// something else went wrong $result will be false
    $result    = move_uploaded_file($tmpName, $filePath);
if (!$result) {
	echo "Error uploading file";
	exit;
}

// end file upload

if(!get_magic_quotes_gpc())
{
	$title   = addslashes($title);
	$content = addslashes($content);
	$fileName  = addslashes($fileName);
        $filePath  = addslashes($filePath);
}
include 'library/config.php';
include 'library/opendb.php';                   


$query = "INSERT INTO courses (title, content, name, size, type, path) VALUES ('$title', '$content', '$fileName', '$fileSize', '$fileType', '$filePath')";
mysql_query($query) or die('Error, query failed : ' . mysql_error()); 
include 'library/closedb.php';

echo "<div class=\"alert\">Course '$title' added</div>";
echo "<br>File uploaded<br>";
}
?>
<form action="" method="post" enctype="multipart/form-data" name="uploadform">
  <table width="700" border="0" cellpadding="2" cellspacing="1" class="box" align="center">
    <tr> 
      <td width="100">Title</td>
      <td><input name="title" type="text" class="box" id="title"></td>
    </tr>
    <tr> 
      <td width="100" valign="top">Content</td>
      <td><textarea name="content" cols="80" rows="80" class="box" id="content"></textarea></td>
    </tr>
    <tr> 
      <td width="100">pdf upload </td>
      <td><table width="350" border="0" cellpadding="1" cellspacing="1" class="box">

      <td width="80"></td>
    </tr>
  </table></td>
    </tr>
    <tr> 
      <td colspan="2" align="center"><input name="save" type="submit" class="box" id="save" value="Save Article"></td>
    </tr>
  </table>
</form>

 

and this is my download script:

error_reporting(E_ALL);
if(isset($_GET['id']))
{

include 'library/opendb.php';

$id      = $_GET['id'];

$result  = mysql_query($query) or die('Error, query failed');
list($name, $type, $size, $filePath) = mysql_fetch_array($result);

header("Content-Disposition: attachment; filename=$name");
header("Content-length: $size");
header("Content-type: $type");

readfile($filePath);

exit;

If you know the exact path of your PDF, try this?

 

download.php

header("Pragma: public"); // required
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false); // required for certain browsers 
header("Content-Type: application/pdf");
header("Content-Disposition: attachment; filename=\"".basename($filename)."\";" );
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize($filename));
readfile("$filename");
exit();

 

user by download.php?filename=PDF.pdf

Try doing a base64_encode when putting it into the database.

 

$fp = fopen($_FILES['userfile']['tmp_name'], 'r');
				$content = fread($fp, filesize($_FILES['userfile']['tmp_name']));
				$content = base64_encode($content);
...insert into db with $content...

 

and then on the download page, do the same thing but with a base64_decode.

 

Not sure if that's the problem, but I know I had a lot of problems with PDFs read into my database before I did this.
