Загрузка изображения с помощью codeigniter

Question

Я пытаюсь загрузить изображение и сохранить полный путь к изображениям в моей таблице изображений, но я не знаю, как получить полный путь из массива $this->upload->data(), это мой код ниже.

//assigns the user's sessioned id to the variable $user_id 

$user_id = $this->session->userdata('user_id'); 

//sets rules for the image that is being uploaded 
$config['overwrite'] = FALSE; //does not overwrite any image adds +1 instead 
$config['encrypt_name'] = FALSE; //encrypts the images name 
$config['remove_spaces'] = TRUE; //removes spaces from the images name 
$config['file_name'] = $user_id."_0.jpg";/*gives the image a new name combination of the user's id and a number*/ 
$config['upload_path'] = './uploads'; // the uploaded images path 
$config['allowed_types'] = 'jpg|png';/*types of image extentions allowed to be uploaded*/ 
$config['max_size'] = '2048';// maximum file size that can be uploaded (2MB) 

if (! is_dir($config['upload_path'])) /* this checks to see if the file path is wrong or does not exist.*/ 
    die("THE UPLOAD DIRECTORY DOES NOT EXIST"); // error for invalid file path 

$this->load->library('upload',$config); /* this loads codeigniters file upload library*/ 
//this checks for errors incase the image upload breaks a set rule. 
if (! $this->upload->do_upload()) { 
    echo "UPLOAD ERROR ! ".$this->upload->display_errors(); //image error 
} 
else { 
    // success message to show that the image was successfuly uploaded. 
    echo "THE IMAGE HAS BEEN UPLOADED : "; var_dump($this->upload->data()); 
}

Вы должны видеть на свалке для $this->upload->data() следующий массив:

Array 
(
    [file_name] => mypic.jpg 
    [file_type] => image/jpeg 
    [file_path] => /path/to/your/upload/ 
    [full_path] => /path/to/your/upload/jpg.jpg 
    [raw_name]  => mypic 
    [orig_name] => mypic.jpg 
    [client_name] => mypic.jpg 
    [file_ext]  => .jpg 
    [file_size] => 22.2 
    [is_image]  => 1 
    [image_width] => 800 
    [image_height] => 600 
    [image_type] => jpeg 
    [image_size_str] => width="800" height="200" 
) 

Таким образом, вы можете просто использовать что-то вроде:

if ($uploaded_image = $this->upload->do_upload()){ 
    // success message to show that the image was successfuly uploaded. 
    echo "THE IMAGE HAS BEEN UPLOADED : "; 
    $full_path = $uploaded_image['full_path']; 
} else { 
    echo "UPLOAD ERROR ! ".$this->upload->display_errors();//image error 
}

Все, что мне нужно было сделать, чтобы сохранить массив $this->upload->data(); в переменной, например

$image_info = $this->upload->data(); 

и из переменной $image_info я могу получить доступ к таким свойствам изображений.

$image_info['full_path']; 
$image_info['file_name'];
