Migration from Linux to Windows

[RFH Reseller: UKFlyer]

I have a site hosted with another company on a Linux server. It's written in PHP, and involves image uploads, however after migrating it across to a Red Fox server certain elements don't work.

I have a couple of mods I need doing to it as well - anybody interested in having a look and giving me a price for the job?

I can't take on any projects, but feel free to post the errors you are encountering as I may be able to help…

I did a move a few webistes from Linux to Windows IIS. One of them contained a upload script as well and showed an error becuase of the diffrent file paths used by windows.

I can't remember the excacte staps I took, but it was verly easy. I justed corrected the path to where the script saved the uploaded files to.

On the functionality side when an image is uploaded I get this error message:

Warning: exec() [function.exec.php]: Unable to fork [/usr/bin/convert ../uploads/original/0.jpg ../uploads/original/0.jpg.tif] in D:\wearegraduating.com\wwwroot\inc\imagemanip.php on line 91
Looked up /usr/bin and got the following: a directory on Unix-like operating systems that contains most of the executable files (i.e., ready-to-run programs) that are not needed for booting (i.e., starting) or repairing the system.

Got the reply from Warren:

It seems the PHP script is using Linux's CONVERT to convert a JPG image into a TIF image - Windows doesn't natively support anything like this so there is no simple quick fix.


It does do that - create a tif as well as a jpg - it's something that I never understood happened.. I only need a jpg, however I do want the image zipped and stored in a separate directory - it's so when it's re-downloaded a download dialog box is forced as opposed to the image opening in a browser... I have got a bit of script that will do that but haven't been able to integrate it and get it to work...

Help would be appreciated if you can ....

You don't actually need to zip the file to make it download. The method I would tend to use is to push the request for the file/image through a script that reads in the real file's data and passes it out to the browser. This allows you to set headers, forcing the download, and also gives you a significant amount of flexibility for throttling and tracking downloads:

if ($filehandle = fopen($filepath, 'rb')) { //open binary file for reading

    header("Cache-Control: no-cache, must-revalidate");
    header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); 
    header('Content-type: application/force-download');
    header('Content-Disposition: attachment; filename="' . $filename . '";' );
    header('Content-Length: ' . filesize($filepath));
    header('Content-Transfer-Encoding: binary');

    while( !feof($filehandle) && connection_status()==0 ) {
        echo fread($filehandle, 1024*8);//send in 1kb chunks
        flush();
    }
    fclose($file);
} 

I've not tested that code, but I hope it demonstrates what I mean.

Changing the subject slightly; to download the file I have this line of code:

<a href="/form.php?<?= $crow['gid'] .jpg; ?>"

However the full stop is not being recognised, so the resultant link is form.php?202jpg and not form.php?202.jpg which is what I'm after - that is on the linux server....

The way the system works is you click on a link to purchase an image giving you the result above the form processes the info and a payment box appears, you text a code to a specific number and you are given a code back. When that is place in the payment box you will then be redirected to the directory where the image is and low and behold 202.jpg appears. However you can see the image path and probably guess the way to download other images in the directory, hence the reason for forcing a download.

I don't honestly know how would I use the code you have supplied to achieve that.

The system does work as I have tried it with hard coded variables and manaul uploads of jpgs and zip files.

That's improving the functionality of the site Would still like to transfer it onto Red Fox servers, but need to overcome the image upload issue. I also have applet which I have purchased - which makes file uploads easy - again tried it by hard coding in a simple scenario, but don't have a clue how to add it to the current site.

The original developer at the company I used to design the site has moved on and I've lost faith in the current set up to come up with the goods....

<a href="/form.php?<?= $crow['gid'] .jpg; ?>"

It should be:

<a href="/form.php?<?=$crow['gid'] . '.jpg'; ?>"

[RFH Reseller: nick]

<a href="/form.php?<?= $crow['gid'] . '.jpg'; ?>"

[edit]as Warren has said[/edit]

Is the way you need to write that bit.

The snippet I gave looks like it would go somewhere in that form.php script. By the sound of it, the program already works in the way I had been describing.

You are welcome to PM me any URL and/or FTP details etc. and I'll have a quick look. I'm on the road most of the next few days however so may be a little slow at responding.

The script I have uses mod_rewrite to create virtual directories on a linux server. Will enabling URL rewriting produce the same result (a previous post states that URL rewriting works in the same way) - I'm assuming an element of code modification would be required...?
