I am currently trying to do an upload and download. In the download there will be a compile feature.
The idea is the file that I upload have the same name as the compiled file that will be downloaded.
Right now, there is three button in the browser : browse button, upload button and download button.
If I browse the file first .There will be some text on the browse button. If I press upload, the file is uploaded to my local server and some text that show the file is generated.
If after this, I press compile, nothing happen.
If I browse the file. Then the text appear. Then press download instead of upload. There will be exe file that is compiled.
How should I arrange the code, so that the sequence will be I browse, upload, compile not the current one where I browse upload and browse compile?

Below is my code:
Syntax: [ Download ] [ Hide ]
echo"<form action='' method=POST enctype=multipart/form-data>";
echo"<input type=file name=uploadedfile>";
echo"<input type=submit name=upload value=Upload>";
echo"<input type=submit value=Download name=download>";

//check if upload is selected
    //Check the availability of the file. empty evaluate to true if empty. check if it is the recent uploaded file. validate filename
    if((!empty($_FILES["uploadedfile"])) && ($_FILES['uploadedfile']['error'] == 0) && (is_uploaded_file($_FILES['uploadedfile']['tmp_name'])) && (preg_match("/^[A-Za-z0-9].*\.[a-z]{0,3}$/",$_FILES['uploadedfile']['tmp_name'])))
        //basename return component name. strtolower change to lowercase.
        $filename       = strtolower    (basename($_FILES['uploadedfile']['name']));
        //substr return some string after dot
        $ext            = substr        ($filename, strrpos($filename, '.') + 1);
        //check if file extension is c and less than 100000kb
        if (($ext=="c") && ($_FILES["uploadedfile"]["size"] < 100000) && ($_FILES["uploadedfile"]["type"] == "text/plain"))
            //add the dot
            //file directory
            //move_uploaded_file is php function for directory
            if ((move_uploaded_file($_FILES['uploadedfile']['tmp_name'],$newname)))
                print('<tr><td width=100px>File Name</td><td width=100px>File Size</td><td width=100px>Last Modified</td></tr>');
                print('<tr><td>'. $_FILES['uploadedfile']['name'] . '</td><td>'. round($_FILES['uploadedfile']['size']/1024,4) . ' Kb</td><td>'.date("d F Y H:i:s.", filemtime($newname)).'</td></tr>');
        print('Error: Only .c files <500Kb');
else if((isset($_POST['download'])))
    echo $source;
    $destination = 'upload\\' . pathinfo($_FILES['uploadedfile']['name'], PATHINFO_FILENAME) . '.exe';
    echo $destination;
    $output = system('"C:\Program Files\CodeBlocks\MinGW\bin\gcc.exe" '.$source.' -O3 -o '.$destination);
    echo $output;
    $outputfilename     = strtolower(basename($destination));
    $extension          = substr        ($outputfilename, strrpos($outputfilename, '.') + 1);
    if ($extension=="exe")
    //check file exist
        if (file_exists($destination))
        //header=send a raw http header will do a download
        header('Content-Description: File Transfer');
        //tell browser type of file downloaded
        header('Content-Type: application/octet-stream');
        //attachment = tell browser that going to link a file
        //the name will be the same as $file.
        header('Content-Disposition: attachment; filename='.basename($outputfilename));
        //to prevent cache either by proxy or client browser
        header('Content-Transfer-Encoding: binary');
        header('Expires: 0');
        //compared it with the original server
        header('Cache-Control: must-revalidate');
        //to make IE accept download
        header('Pragma: public');
        // header('Content-Length: ' . filesize($file));
        header('X-Sendfile :'.$outputfilename);
        //erase output buffer
        //flush output buffer
        //output a file

Thanks in advance
