image not insert in mysql using codeigniter

Your form must have the multipart attribute in HTML file like below :

If you're using form helper, then it should be

<?php echo form_open_multipart('/save');?>

Else your form should have the enctype attribute like below

<form enctype="multipart/form-data">

Then the uploaded data result $this->upload->data() will come in array. So you can't store your array in mysql column. So you need to get the filename from $this->upload->data() and store it in a variable like below.

Your Controller should be

public function save(){ $this->load->model('Partner_model'); $feature = $this->input->post('feature'); $config['upload_path']          = './uploads/files'; $config['allowed_types']        = 'gif|jpg|png'; $config['max_size']             = 100; $config['max_width']            = 1024; $config['max_height']           = 768; $this->load->library('upload', $config); if ( ! $this->upload->do_upload('image')){   $error = array('error' => $this->upload->display_errors());   $this->load->view('partner_profile', $error); }else{  $imageArray = $this->upload->data();  $image =  $imageArray['file_name'];  $user_data= array(   'pname' => $this->input->post('pname'),   'type' => $this->input->post('type'),   'address' => $this->input->post('address'),   'about' => $this->input->post('about'),   'city' => $this->input->post('city'),   'code' => $this->input->post('code'),   'state'=>$this->input->post('state'),   'feature'=>implode(",",$feature),   'image' => $image  );   } if($this->Partner_model->save($user_data)) {   $msg = "save sucesss" ; }else {   $msg = "not save"; } $this->session->set_flashdata('msg', $msg); $this->load->view('partner_profile');}
