PHP - Document Downloads Instead Of Opens

Hi all,

I've tried many, many variations of php download script using readfile() fread() fpassthru() etc... but none seem reliable. I can download small files perfectly fine, but say I have a 30 or 90mb zip file the download ocassionally bombs out and says the download is complete even though the full file hasn't been transferred.
I have tired it on several browsers with pretty much the same issue. The interesting bit for me is that if I download the same file across different browsers (whether or not they start at the same time or not) on my computer the download stops at the same time (not same point into download) for each browser.  Its as if the connection is being reset on my website on a global basis...

The important part of my script as it is at the moment:

Code: [Select]
// resumable download?
$is_resume = TRUE;

//Gather relevant info about file
$size = filesize($path);
$fileinfo = pathinfo($path);

@ini_set('magic_quotes_runtime', 0);
set_time_limit(0);
apache_setenv('no-gzip', '1');
mb_http_output("pass");

// required for IE, otherwise Content-disposition is ignored
if(ini_get('zlib.output_compression')) { ini_set('zlib.output_compression', 'Off'); }
 
//workaround for IE filename bug with multiple periods / multiple dots in filename
//that adds square brackets to filename - eg. setup.abc.exe becomes setup[1].abc.exe
$filename = (strstr($_SERVER['HTTP_USER_AGENT'], 'MSIE')) ?
preg_replace('/\./', '%2e', $fileinfo['basename'], substr_count($fileinfo['basename'], '.') - 1) :
$fileinfo['basename'];

$file_extension = strtolower($fileinfo['extension']);

    //This will set the Content-Type to the appropriate setting for the file
    switch($file_extension) {
        case 'zip': $ctype='application/zip'; break;
        case 'pdf': $ctype='application/pdf'; break;
        default:    $ctype='application/force-download';
    }

    //check if http_range is sent by browser (or download manager)
    if($is_resume && isset($_SERVER['HTTP_RANGE'])) {
        list($size_unit, $range_orig) = explode('=', $_SERVER['HTTP_RANGE'], 2);
        if ($size_unit == 'bytes') {
            //multiple ranges could be specified at the same time, but for simplicity only serve the first range
            //http://tools.ietf.org/id/draft-ietf-http-range-retrieval-00.txt
            list($range, $extra_ranges) = explode(',', $range_orig, 2);
        } else {
            $range = '';
        }
    } else {
        $range = '';
    }

    //figure out download piece from range (if set)
    list($seek_start, $seek_end) = explode('-', $range, 2);

    //set start and end based on range (if set), else set defaults
    //also check for invalid ranges.
    $seek_end = (empty($seek_end)) ? ($size - 1) : min(abs(intval($seek_end)),($size - 1));
    $seek_start = (empty($seek_start) || $seek_end < abs(intval($seek_start))) ? 0 : max(abs(intval($seek_start)),0);

    //add headers if resumable
    if ($is_resume) {
        //Only send partial content header if downloading a piece of the file (IE workaround)
        if ($seek_start > 0 || $seek_end < ($size - 1)) {
            header('HTTP/1.1 206 Partial Content');
        }
header('Accept-Ranges: bytes');
        header('Content-Range: bytes '.$seek_start.'-'.$seek_end.'/'.$size);
    }

    header("Cache-Control: cache, must-revalidate"); 
    header("Pragma: public");
    header('Content-Type: ' . $ctype);
    header("Content-Disposition: attachment; filename=\"".$filename."\"");
    header('Content-Length: '.($seek_end - $seek_start + 1));

    //open the file
    $fp = fopen($path, 'rb');
    //seek to start of missing part
    fseek($fp, $seek_start);

    //start buffered download
    while(!feof($fp)) {
        //reset time limit for big files
        set_time_limit(0);
        print(fread($fp, 1024*8));
        flush();
        ob_flush();
    }
    fclose($fp);
exit();

I did have the following section in replace of the above fread section up until this morning (but same issue):

Code: [Select]
// http headers for zip downloads
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=\"".$filename."\"");
header("Content-Transfer-Encoding: binary");
header('Content-Length: '.$size);
ob_end_flush();
@readfile($path);

I have tried different headers and so forth, but all generally seem to bomb out occassionally before the download completes. But they don't bomb out at a particular point in the file size (ie at 25mb). Just seems to work and then die at the same time across different browsers, even when they are started at different times.

Very strange and I've spent days modifying the script and still no answers. Sometimes the files download fine, but bomb out too many times for it to be satifactory to leave.

Any help or pointers would be much appreciated.

So, I have a script that works downloading a file - excerpt below:

Code: [Select]
header("Pragma: public");
header("Expires: 0");
header('Content-type: "application/octet-stream"');
header("Cache-Control: private",false);
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
$f = "Content-Disposition: attachment; filename=\"".$myfile['downloadname'].".".$myfile['ext']."\"";
header($f);
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize($file));
    ob_clean();
    flush();
readfile("$file");
exit();
I record elsewhere in a mysql database when the script is started.

In addition, I'd like to be able to record whether the download completes (successfully or otherwise). 

As it is, the script can run and the user press cancel and it looks like a download but isn't.

Is this possible?  If so, how?

Your help, as ever, gratefully received.

I would like to be able to add a yes/no to a field in a 'user' database when a logged in user clicks on a link to download a file.
The site I have built stores docs and applications. and my client would like to know which user has downloaded a certain application (clicked on a button to 'download' and installer file.
Is this possible?

Hi,

Firstly, apologies if this is in the wrong place in the forum to post this.

I have a website, I use PHP in various places to pull/push info from/to a mySQL database, i'm fairly happy with PHP and its uses.

I've recently started to use the Google checkout widget on the site for a proposed webstore (to go live at a later date), this has the ability to 'sell' download URL's or keys.

I like the idea of a customer being able to purchase multiple MP3 downloads and them being given a URL that gives them the links for the MP3's selected.

This is probably beyond anything i've ever done with PHP though so I need to understand the architecture........I understand that, given a list of items from the store, I can run a query to display a list of stored URL's  for those items - and I'm sure I can find code that will give me a random URL that will 'expire' after an amount of time.
My question is, how to get the list of items ordered from the google checkout?? I'm sure this has something to do with API's - but I don't know what they are, presumably there is some kind of table in Google that I can tap into to get the product info??

any help would be very much appreciated.

....oh, and i'm sure people are going to ask "why are you using Google checkout", the answer being, for me, it seems simple, effective and free! (but i'm open to suggestions.)

Hi,

I have downloads that are available for users. They can click the links to download the file. Once they do this, I have a query that updates the number of downloads that file has received. I need to create a query that adds up all the rows Total Downloads.

So for example: i have 3 rows:
Name       -       Total Downloads
First       -          2
Second       -        23
Third       -          7

Using the query for these rows would give me an amount of 32.

Any idea how to do this?

I don't want to have to create a new column to find the total number of downloads. Any other ways?

Ive tried
<?php
$file = file_get_contents('./time.php');
echo $file;
?>
This just outputs the php, how can I make it just the out php output value.
ty in advance.

im using dom to tidy up my html but i wondering is there a way to format my html like so

<dl>
     <dd>
            <label>Condition :</label>
            <select name="condition"><option value="New">New</option>
      </dd>
</dl>

insead of

<dl>
<dd>
<label>Condition :</label>
<select name="condition"><option value="New">New</option>
</dd>
</dl>

here is the php im using

$dom = new DOMDocument();
$dom->loadHTML($this->_body);
$dom->formatOutput = true;
echo $dom->saveHTML();

thank you

I'm using a here document for the html in my php page. In it I call a function to get the correct value to pass to the form and eventually to the next php page. I'm getting an error:Array to string conversion in. I'm not sure why, maybe I'm escaping the double quotes wrong? or do you need to do something special when the value being submitted is an array?   This line is where the error is, the second table data in the first table row

<td><input name="choice" type="radio" value=\"getCardValues($pyramid, 0,0)\" /></td>

in here

$output =<<< _HTML_
    
    <!DOCTYPE html>

    <html>
    <head>
        <title>Pyramid Solitaire</title>
    </head>
    
    <body>
        <div class="main">
        <h1>Rock Paper Scissors Game</h1>
        
        <form action="rps.php" method="post">
            <input type="text" name="name">
            <input type="hidden" name="past" value="0">
                
            <table width="20%">
                <tr>
                    <td><img src="./images/cards/getCardFile($pyramid, 0,0)" width="100" height="100" /></td>
                    <td><input name="choice" type="radio" value=\"getCardValues($pyramid, 0,0)\" /></td>
                </tr>
                
                for($i = 0; $i < 2; $i++)
                {
                    <tr>
                        <td><img src="./images/cards/getCardFile($pyramid, 1,$i)" width="100" height="100" /></td>
                        <td><input name="choice" type="radio" value="getCardValues($pyramid, 1,$i)" /></td>
                    </tr>
                }

and so on...   This is the function being called:

function getCardValues($array, $row, $col)
    {        
        $valuesHolder = array($array[$row][$col].getFace(), $array[$row][$col].getSuit());
        
        return $valuesHolder;
    }

so I want to know how I could upload a document associated with an event.......with a form upload.......but where do I store it at and make it display in the view page for the event......?

Hi Folks,


I am trying to scrape the price data from a webpage, but how to get the variable,

see here the target http://www.buergerstiftungen.de/cps/rde/xchg/SID-635E10F9-BFA1A4BF/buergerstiftungen/hs.xsl/db.htm

Code: [Select]
include 'simple_html_dom.php';
$html1 = file_get_html('http://www.buergerstiftungen.de/cps/rde/xchg/SID-635E10F9-BFA1A4BF/buergerstiftungen/hs.xsl/db.htm');

$info1 = $html1->find('b[class=[what to enter herer ]',0);

The variable then also contains data such as

<b class="info"> info </b>

Is there a way to trim the unwanted data out ? I just need all the infos out of the site. I am unsure if I do it during the find, or perhaps when i echo out the variable, then do I specify what I want ?
well how t o do it witout a regex but with DOM-Document!?

I've been using php for a while now to create forms, up until now i've always transmitted the form data to a new php document that then processes them. I wanna take this to the next level and start trying to process the data within the same document. I know this has something to do with checking if the submit button is pressed and then processing the submitted data but thats about as far as my knowledge goes.

Can anyone help me out on  how i can achieve this type of thing. The reason is that i've found a way to execute php code within a joomla 1.6 environment without having to use the iframe option. I know the iframe option may be easier in a way of doing things but its out of the question. The final fase of the php will output code that will trigger a specific joomla plugin to do some specific action. If i pull a php document via an iframe the plugin doesnt trigger as it only gets triggered after the joomla "afterRender" (or something" has executed. If i use the iframe option then that rendering never gets used so the plugin doesnt get triggered.

So in a nutshell, i wanna create forms that submit data and that data gets processed in the same document (in this case joomla article). How do i go about doing this.

Hi all,

I can't get this code to work, if you can tel me what I am doing wrong I would be gratefull.

This is my XML file:

Code: [Select]
<?xml version="1.0" encoding="UTF-8"?>
<popis>
     <student>
          <prezime>Brkic</prezime>
          <ime>Ivica</ime>
          <index>D-142</index>
     </student>
     <student>
          <prezime>Cizek</prezime>
          <ime>Pero</ime>
          <index>D-143</index>
     </student>
</popis>
This is the form I wanna use to change nodes:

<form action="zamjena.php" method="post" enctype="multipart/form-data">
 <table>
   <tr>  
     <td colspan="2"class="labelcell"><label for="ime">Ime:</label></td>
     <td colspan="2"class="fieldcell"><input type="text" id="ime" name="ime"  tabindex="1"/></td>
   </tr>
      <tr>  
     <td colspan="2"class="labelcell"><label for="prezime">Prezime:</label></td>
     <td colspan="2"class="fieldcell"> <input type="text" id="prezime" name="prezime"  tabindex="2"/><br />
</td>
   </tr>
        <tr>  
     <td colspan="2"class="labelcell"><label for="index">Index:</label></td>
     <td colspan="2"class="fieldcell"> <input type="text" id="index" name="index"  tabindex="3"/> <br />
</td>
   </tr>
<tr>  
     <td colspan="2"class="labelcell"><label for="index">ID:</label></td>
     <td colspan="2"class="fieldcell"> <input type="text" id="id" name="id"  tabindex="4"/> <br />
</td>
   </tr>
   <td colspan="4"><input type="submit" name="upload" class="box" value="Zamjeni" tabindex="5" /></td>
  </table>
</form>


"id" is the mark which node to change

And this is code for changin nodes, I found it on: http://us.php.net/manual/en/domnode.replacechild.php :


<?php
// Create a new document fragment to hold the new <student> node
$student = new DomDocument;
$student_node = $student ->createElement('student');

// Add some children
$student_node->appendChild($student->createElement('ime', '$_POST['ime']'));
$student_node->appendChild($student->createElement('prezime', '$_POST['prezime']'));
$student_node->appendChild($student->createElement('index', '$_POST['index']'));


// Add the keywordset into the new document
// The $student variable now holds the new node as a document fragment
$student->appendChild($student_node);
?>

Next, we need to locate the old node:

<?php
// Load the XML
$dom = new DomDocument;
$dom->loadXML($xml);

// Locate the old student node
$xpath = new DOMXpath($dom);
$nodelist = $xpath->query('/popis/student');
$oldnode = $nodelist->item($_POST['id']);
?>

We then import and replace the new node:

<?php
// Load the $student document fragment into the current document
$newnode = $dom->importNode($student->documentElement, true);

// Replace
$oldnode->studentNode->replaceChild($newnode, $oldnode);

// Display
echo $dom->saveXML();
?>

thanks for help

Hey y'all.   I'll gladly admit that I'm not a server guy - I have the utmost respect for people comfortable enough with *nix to handle Apache setup and configuration in a production environment. I can noodle about in *nix typically without killing anything vitally important, but trust me when I say no-one wants me to be a server administrator. That having been said, I do have a development server behind my home network firewall running Ubuntu that I use to test and develop the sites that I create on my separate Windows box. So I try to keep up with the way a shared server would be set up in a real-world situation, to a degree. For instance, I haven't bothered setting up the mail server or FTP, but I do create virtual host files for each of my projects.   So, I've got a virtual host set up on the directory /var/www/myAwesomeSite.com/ with the .conf file containing the following configuration:

<VirtualHost *:80>
	ServerAdmin webmaster@localhost
	ServerName myAwesomeSite.com
	DocumentRoot /var/www/myAwesomeSite.com/www
	<Directory /var/www/myAwesomeSite.com/www>
		AllowOverride All
	</Directory>
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

Now, in my php scripts echoing out $_SERVER['DOCUMENT_ROOT'] gives me 'myAwesomeSite/www' as I would expect. And using $_SERVER['DOCUMENT_ROOT'] in any require() statements actually does include the requested file, so that part seems to be working fine. My question is this: when I use a leading slash ('/'), shouldn't that equate to the document root? I use it at work all the time and it works flawlessly, but on the dev server I have set up here, it's a no-go. Is there another config command that I need to issue to make it work, or am I crazy?   Basically, am I missing a setting somewhere that will make this:

require_once('/path/to/my/include.php');

work like this?

require_once($_SERVER['DOCUMENT_ROOT'].'/to/my/include.php');

*edit* I just realized that I used the wrong slash in the title of this post, but I don't see a way to change the topic title. crap.

how do I make document upload fields like the ones that are on this website where there is a link at the bottom to make another field appear, or make it so that a new field automatically appears when the first one has info in it.  Does this make sense?  and also how would i make these submit with the form seeing as that they would have different field names, wouldn't they?

Hi everyone.

I have been looking for a PHP upload script that handles various different document types like PDF, DOC and XLS. So far all I have found is image upload scripts. Can anyone point me in the right direction? I would be most greatful.

Thank you!
