Error submitting a form with upload pic option. PHP Codeigniter

I've been trying to upload a pic to a folder and store its path in the database, my code seems to work correctly, but no it's not, After i click submit button, it goes to a blank page. Using Inspect element, Network option in my browser, when seeing the parameters sent I see correct input from the text fields but for the image, Content-Disposition: form-data; name="myimage"; filename="IMG_8971.JPG" Content-Type: image/jpeg Plus some other weirly looking characters and symbols like :
