need help converting ajax img upload to img object

[The14thGOD]

I apologize if I am using the wrong terminology here...

 

I am trying to take an image that is dragged and dropped and then uploading the image to a server to do other things with it. I've found very generic example(s) that can just move the file, but I need to be able to manipulate it on the server.

 

AJAX cut-out code:

var xhr = new XMLHttpRequest();  
    			if(xhr.upload && file.type == 'image/jpeg' || file.type == 'image/png'){
    				xhr.open('POST', 'path/to/script.php', true);  
			    xhr.setRequestHeader('X_FILENAME', file.name);
			    xhr.send(file);
    			}

The above part works but when I try to manipulate it with PHP it doesn't see it as a typical $_FILES variable. Ideally I would like to get it to be like that, if not I understand I will have to change stuff. Here is my PHP that handles the above call:

<?php
$slide = new Slide();
//echo gettype($_SERVER['HTTP_X_FILENAME']); //str
$file = file_get_contents('php://input');
$image = base64_decode($file);
if($slide->add_image_to_slide($_GET['sid'],$image)){
	echo 'yay';
}else{
	echo $slide->error;
}

 

Object Code:

<?php
public function add_image_to_slide($id,$image){
 		//Verify image before proceeding forward
 		$accepted_file_types = array('jpg','png');
		$ext = explode('.',$image['name']);
		if(array_search($ext[1],$accepted_file_types) !== false) {	
			//variables
			$this->id = $id;
			$this->select_slide($this->id);

			//make sure that the folders for the images to go actually exist, if not, create them
			$this->create_folders();	
			$this->generate_thumbnail($image);

			$this->thumbnail = $this->upload_directory.$this->rand_id.'_thumb_'.$this->filename;	
			$this->full_img = $this->upload_directory.$this->rand_id.'_'.$this->filename;			

			// thumbnail is moved automatically by function above, just move full image
			move_uploaded_file($image['tmp_name'], BASE_ROOT.'/'.$this->full_img);

			if($stmt = $this->_db->prepare('UPDATE slides SET full_img = ? , thumbnail = ? WHERE id = ?')){
				$stmt->bind_param('ssi',$this->full_img,$this->thumbnail,$id);
				$stmt->execute();
				$stmt->close();
				return true;
			}
			return false;
		}
		$this->error = 'File Extension Error: .jpg, .png allowed only';
 		return false;
 	}

 

Right now it's skipping straight to $this->error since it's not an image object. I'm not really sure what to pursue from here. I did try this line once but it also skipped to the error line:

<?php
$image = createimagefromstr(file_get_contents('php://input'));

 

Any help would be greatly appreciated!

 

Thanks,

Thank you for posting the solution. Months from now, somebody will mentally thank you for it. (Unlike those guys that say "It's OK, I found a solution" and never elaborate.
