QR Code

[neumannon]

Anyone try adding a scannable code (QR Code or whatever) to the file download file page? I may mod the download php page if it hasn't been done. That may be a cool feature for a future release.

At the moment there are no QR Codes/scannable codes in any DFH release, but feel free to mod this into the download page . If successful, it will be included in a future release.

I was able to mod the download.php file to show a qr code for downloading the file on a mobile device. It was actually quite simple using the google qr code api. When I have a chance, I will post the code with a screenshot of the result. I am a noob to php so there may have been a better way to implement but it works and I'm happy . Stay tuned...

No ones 100% when it comes to coding and besides, the more one codes the more experience he/she will gain in how to (style) code more efficiently. Well done and I look forward to your mod.

Alright! I am testing the image upload feature of the site. For some reason when I tried uploading a png file, it said the file wasn't allowed even though png is in the list of allowed image formats. Must not have support for png images yet. No biggie though. I just removed .png as a possible image format for upload. I was able to get the jpg screenshot uploaded.

So here is the download.php screenshot modded for qr code...


I added the below code to the [root]/download.php file. There are various parameters for the google function which can be adjusted. I left the defaults alone and seems to work well. There may be an easier way to get the current URL for encoding but that was the one I was able to find.

Code: Select all

function generateQRwithGoogle($chl,$widhtHeight ='150',$EC_level='L',$margin='0')
 {
     $url = urlencode($url);
     echo '<img src="http://chart.apis.google.com/chart?chs='.$widhtHeight.
'x'.$widhtHeight.'&cht=qr&chld='.$EC_level.'|'.$margin.
'&chl='.$chl.'" alt="QR code" widhtHeight="'.$size.
'" widhtHeight="'.$size.'"/>';
 }

function currPageURL()
{
 $pageURL = 'http';
 if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
 $pageURL .= "://";
 if ($_SERVER["SERVER_PORT"] != "80") {
  $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
 } else {
  $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
 }
 return $pageURL;
}


Then I added this line to [root]/styles/Indigo/download.php at the bottom of the table. Of course it can be put anywhere on the page.

Code: Select all

<?php
$urlToEncode=currPageURL();
?>

<tr><td align=left valign=top bgcolor=#F4F4F4 background="img/button03.gif\">QR Code: </td><td bgcolor=#EEF4FB background="img/button03.gif"><?php generateQRwithGoogle($urlToEncode);?></td></tr>


I hope that helps out anyone interested in doing the same thing. If there is an easier/simpler way to do any of this, please let me know and I'll make the change.

And this was done on the 1.2.3 DFH release.

And don't try to scan that code btw. I just loaded DFH the other day and I have only been doing testing on the local host. so the URL for that code is localhost and not my actual public hostname. I just did test using my public domain name and it worked perfectly on my phone. WooHoo!

[neumannon]

I suppose I could also add that to the view image page as well.

[neumannon]

Image viewer page has been modded too. Takes me right to the image on my phone.

[SamEA]

Any functioning demo available? Thank you.

[neumannon]

Ha, in my excitement I forgot to post demos.

Here is one for a normal file download.

Here is one for the image viewer.
