Question

i am using CI 2.1.0 and mysql database for one of my projects. i am facing a problem with my image uploading method. the image i am uploading should be saved in uploads directory and create a thumbnail version of the image and the image path should be saved in database.
the code i have done works fine but there is one problem that when i upload an image, in the upload directory i get two copies of the same image and in the thumbs directory a single copy of the uploaded image. i want to have only one copy of the image instead of those two copies .
here is my code->

model:

function do_upload() //to upload images in upload directory
        {
            $i=$this->db->get('portfolio')->num_rows();
            $i=$i+1;
            $image_path=realpath(APPPATH . '../uploads');
            $config=array(
                'allowed_types'=>'jpeg|png|gif|jpg',
                'upload_path'=>$image_path,
                'max_size'=>2097152,
                'file_name'=>'_'.$i.'_'
            );
            $this->load->library('upload', $config);
            $this->upload->do_upload();
            $image_data = $this->upload->data();
            $config=array(
                'source_image'=>$image_data['full_path'],
                'new_image'=>$image_path.'/thumbs',
                'maintain_ration'=>TRUE,
                'width'=>150,
                'height'=>100
            );
            $this->load->library('image_lib', $config);
            $this->image_lib->resize();
            if( ! $this->upload->do_upload())
            {
                $error = array('error' => $this->upload->display_errors());
                return $error;
            }
            else
            {
                return $image_data;
            }
        }

some please tell me why two copies of images are being uploaded.
there is anothe thing, i want images to be overwritten if an image with same name exists. i have changed the upload.php file inside system->libraries to this

public $overwrite               = TRUE;

but it is not working. someone please help.

Answer 1

you are calling $this->upload->do_upload() twice ..

Please try this code

Warning : Untested

function do_upload() 

        {
            $i=$this->db->get('portfolio')->num_rows();
            $i=$i+1;

            $image_path=realpath(APPPATH . '../uploads');

            $config=array(
                'allowed_types'=>'jpeg|png|gif|jpg',
                'upload_path'=>$image_path,
                'max_size'=>2097152,
                'overwrite'=>TRUE,
                'file_name'=>'_'.$i.'_'
            );


            $this->load->library('upload', $config);


        if( ! $this->upload->do_upload())
            {
                $error = array('error' => $this->upload->display_errors());
                return $error;
            }
            else
            {

        $image_data = $this->upload->data();
            $config=array(
                'source_image'=>$image_data['full_path'],
                'new_image'=>$image_path.'/thumbs',
                'maintain_ration'=>TRUE,
                'width'=>150,
                'height'=>100
            );
            $this->load->library('image_lib', $config);
            $this->image_lib->resize();
                return $image_data;
            }
        }
