image upload and save path in database using codeigniter

Question

i did not get image upload and save image path in database My table name is uploadimage and controller name is upload.php

Answer 1

I use the following snippet for uploading file with multiple file upload field in the form, saving uploaded file to custom directories and finally saving the file location path to the database

$input1 = $this->input->post('input1'); //Input field value
$input2 = $this->input->post('input2'); //Input field value
$photo1 = ''; //File field value
$photo2 = ''; //File field value

$config['upload_path'] = './photo_gallery/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size']    = '';
$this->load->library('upload', $config);

foreach($_FILES as $key=>$file) {
    //$key will be the field name
    $out_dir = "./photo_gallery/$key";
    if(!file_exists($out_dir)) {
        mkdir($out_dir, '0777', true);
    }
    if ( ! $this->upload->do_upload($key))
    {
        $error = array('error' => $this->upload->display_errors());
    }
    else
    {
        $data = array('upload_data' => $this->upload->data());
        $fileName = $data['upload_data']['file_name'];
        $newName = sha1_file("./photo_gallery/$fileName") . "." . pathinfo("./photo_gallery/$fileName", PATHINFO_EXTENSION);
        rename("./photo_gallery/$fileName", "$out_dir/$newName");
        $$key = "$out_dir/$newName";    //This will assign values for $photo1 and $photo2 with new paths
    }              
}

$data_to_insert = array(
    'input1' => $input1,
    'input2' => $input2,
    'photo1' => $photo1, //Updated with new file path
    'photo2' => $photo2, //Updated with new file path
);

//pass variable $data_to_insert in model function that implements following
$success = $this->db->insert('my_table', $data_to_insert);
return $this->db->insert_id();
