help me on the upload class !!

[PHPycho]

Hello forums

Now i am totally shifting towards OOP..

I had tried to make a upload class but it didnt worked .here is the code

 

uploader.class.php

<?php
class uploader
{
var $uploadDir;
var $thumbDir;
var $newFileName;
/*var $file_name;
var $file_type;
var $file_size;
var $file_temp_dir;*/
var $fileInfo = array();
var $maxFileSize;	
var $allowTypes = array();
var $errMsg = "";
var $suMsg = "";
/***/
var $fileExt;	

function getExtension()
{
	$fileExt = explode(".",$this->$fileInfo['name']);
	$this->fileExt = $fileExt[1];
}

function checkTypes()
{
	if(!in_array($this->fileInfo['type'],$this->allowTypes))
	{
		return FALSE;
	}
	else
		return TRUE;
}		


function doUpload()
{
	// Check the Size
	/* If fileSize > maxSize */
	if($this->fileInfo['size'] > $this->maxFileSize)
	{
		$this->errMsg .= "File Size is larger<br />";
	}

	/* If fileSize == 0 */
	else if($this->fileInfo['size'] == 0)
	{
		$this->errMsg .= "No file uploaded <br />";
	}

	/* Check the Types */
	else if(!$this->checkTypes())
	{
		$this->errMsg .= "Invalid file type !! <br />";
	}

	/* If everything goes fine then Upload */
	else
	{			
		//upload to destDir
		echo "Final step";
		$uploadPath = $this->uploadDir."/".$this->fileInfo['name'];
		move_uploaded_file($this->fileInfo['tmp_name'],$uploadPath);
		//finally rename
		$ext = $this->getExtension();
		$newUploadPath = $this->uploadDir."/".$this->newFileName.".".ext;
		if(rename($uploadPath,$newUploadPath))
		{
			$this->suMsg = "Sucessfully Uploaded & Renamed !!";
		}

	}	
}

function deleteFile()
{
}

function renameFile()
{
}

}
?>

 

action.php

<?php
if(isset($_POST[] ...)
{
  include "uploader.class.php";
$uploaderObj = new uploader();
  //assign all the variable properties of uploader.class.php
$uploaderObj->doUpload();
}
?>

But nothing happens

What i want ?

1>Any techniques for checking how the class is working ie any debugging tips

2>Any changes in above code to  make it efficient and effective Note: its for PHP4 ie any tips n modifications

3> when i try to echo $uploaderObj->getExtension(), it gives the follwing error

Fatal error: Cannot access empty property in C:\Program Files\xampp\htdocs\designtoko\libs\uploader.class.php on line 21

and why it is so

 

Thanks for reading my post.

 

Thanks in advance to all of you and awaiting for the results...

Try this for your uploader class:

 

<?php
class uploader
{
var $uploadDir;
var $thumbDir;
var $newFileName;
var $fileInfo = array();
var $maxFileSize = 1024; // Max filesize of 1024 bytes (1 MB)
var $allowTypes = array();
var $errMsg = array();
var $suMsg = "";
var $fileExt;
var $uploaded = false;
var $fileLocation;

function uploader($file) {
	$this->fileInfo = $file;
}

function getExtension() {
	$fileExt = explode(".",$this->$fileInfo['name']);
	$this->fileExt = $fileExt[1];
}

function checkTypes() {
	if(!in_array($this->fileInfo['type'],$this->allowTypes)) return false;
	return true;
}	

function doUpload($file) {
	if (!$this->fileInfo['tmp_name'])
		$this->errMsg[] = "No file uploaded";
	if ($this->fileInfo['size'] > $this->maxFileSize)
		$this->errMsg[] = "File size is too large";
	if (!$this->checkTypes())
		$this->errMsg[] = "Invalid file type";
	if (!$this->errMsg) {
		$filename = $this->newFileName ? $this->newFileName : $this->fileInfo['name'];
		$this->fileLocation = $uploadPath = $this->uploadDir . "/" . $filename;
		move_uploaded_file($this->fileInfo['tmp_name'], $uploadPath);
		$this->uploaded = true;
	}

}

function deleteFile() {
	if ($this->uploaded)
		return unlink($this->fileLocation);
}

function renameFile($newFilename) {
	if ($this->uploaded)
		return rename($this->fileLocation, $this->uploadDir . "/" . $newFilename);
	else $this->newFileName = $newFilename;
	return true;
}
}
?>

 

Try this for your action file:

<?php
if (isset($_FILES['filename'])) {
    $uploaderObj = new uploader($_FILES['filename']);
    $uploaderObj->doUpload();
}
?>
