Hi Guys,

I've got the flowing code that takes an uploaded pdf and places it in one directory while taking a screenshot of the frontpage and placing that in another directory (ignore the mess!):

<?php
$myFileName;

/**
 * Handle file uploads via XMLHttpRequest
 */
class qqUploadedFileXhr {
    /**
     * Save the file to the specified path
     * @return boolean TRUE on success
     */
    function save($path) {    
        $input = fopen("php://input", "r");
        $temp = tmpfile();
        $realSize = stream_copy_to_stream($input, $temp);
        fclose($input);
        
        if ($realSize != $this->getSize()){            
            return false;
        }
        
        $target = fopen($path, "w");        
        fseek($temp, 0, SEEK_SET);
        stream_copy_to_stream($temp, $target);
        fclose($target);
        
        return true;
    }
    function getName() {
        return $_GET['qqfile'];
    }
    function getSize() {
        if (isset($_SERVER["CONTENT_LENGTH"])){
            return (int)$_SERVER["CONTENT_LENGTH"];            
        } else {
            throw new Exception('Getting content length is not supported.');
        }      
    }   
}
$pathinfo['filename'];

class qqFileUploader {
    private $allowedExtensions = array();
    private $sizeLimit = 10485760;
    private $file;

    function __construct(array $allowedExtensions = array(), $sizeLimit = 10485760){

        if ($postSize < $this->sizeLimit || $uploadSize < $this->sizeLimit){
            $size = max(1, $this->sizeLimit / 1024 / 1024) . 'M';

        }
        return $val;
    }
    
    /**
     * Returns array('success'=>true) or array('error'=>'error message')

    function handleUpload($uploadDirectory, &$str, $replaceOldFile = FALSE){

	//exec("convert /var/www/current/server/test.pdf[0]  /var/www/current/server/uploads/preview/test.jpg");

            $these = implode(', ', $this->allowedExtensions);
            return array('error' => 'File has an invalid extension, ProPaGate only accepts .'. $these . '');
        }
        
        if(!$replaceOldFile){
            /// don't overwrite previous files that were uploaded
            while (file_exists($uploadDirectory . $filename . '.' . $ext)) {
                $filename .= date('(d-m-Y H:i)');
            }
        }
        
        if ($this->file->save($uploadDirectory . $filename . '.' . $ext)){

		$str = $filename . '.' . $ext;
            return array('success'=>true);
        } else {
            return array('error'=> 'Could not save uploaded file.' .

    }    
}

// list of valid extensions, ex. array("jpeg", "xml", "bmp")
$allowedExtensions = array('pdf');
// max file size in bytes
$sizeLimit = 10 * 1024 * 1024;
$uploader = new qqFileUploader($allowedExtensions, $sizeLimit);  
$result = $uploader->handleUpload('uploads/files/', $myFileName);

$com2 = getcwd().'/convert /var/www/current/server/uploads/files/"'.$myFileName.'[0]" /var/www/current/server/uploads/preview/"'.$myFileName.'.jpg"';

exec($com2);
// to pass data through iframe you will need to encode all html tags
echo htmlspecialchars(json_encode($result), ENT_NOQUOTES);

Open in new window


I also need to enter $myFileName into a table in my database
Here is the relevent code:

$con = mysql_connect( "localhost" , "root" , "Mounta1n" );

if (!$con)

  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db('propagate' , $con);

$sql_query = ("INSERT INTO storage (ID, name) VALUES ('NULL', '$myFileName')");
mysql_query($sql_query);

mysql_close($con);

Open in new window



Could somebody put the two together so that the filename will be sent to the database? I've tryed a few ways but i'm having no luck.

Thanks in advance!!!

have a look at the above, change whats needed for your system, seem you are missing the class qqUploadedFileForm so ive hashed that out in the construct
