CodeIgniter：将Image上传到路径和数据库

Question

I'm trying to upload an image to a file path and insert that path to the database. However, the upload always shows the error You did not select a file to upload ..even though I did.

Here's my VIEW

<form action="<?= site_url('profile/profile_submit')?>" method="post" enctype="multipart/form-data">
       <input type="file" class="image-upload" accept="image/*" name="profilePic" id="profilePic"/>
</form>

CONTROLLER

$config['upload_path'] = 'assets/img/profile_img/';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['overwrite'] = TRUE;
$config['max_size'] = "2048000"; 
$config['max_height'] = "768";
$config['max_width'] = "1024";
$this->load->library('upload', $config);
    if ($this->upload->do_upload('profilePic')){
        $data = $this->upload->data();
            $picture = array(
                'photoPath' => $this->upload->data('full_path').$data['file_name']
            );
    }
    else{
            echo $this->upload->display_errors();
    } 

$this->profile_model->submit_profile($picture);

MODEL

function submit_profile($picture){
        $this->db->insert('tbl_st_picture', $picture);
        }

Answer 1

change your upload code as below. Don't use $this->input->post() for getting file data. Also make sure you have added enctype="multipart/form-data" in form

if ($this->upload->do_upload('profilePic')){
       $data = $this->upload->data();
        $picture = array(
                'photoPath' => $this->upload->data('full_path').$data['file_name'],
        );
    }
    else{
            echo $this->upload->display_errors();
    }
