图像上传与codeigniter [英] image uploading with codeigniter

问题描述

我试图上传一个图像并保存图像的完整路径在我的图像表，但我不知道如何获得完整的路径它从 $ this-> upload->数据） array这是我的代码如下。

Am trying to upload an image and save the images full path in my images table but i dont know how to get the full path it out of the $this->upload->data() array this is my code below.

//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() );
}

推荐答案

以存储变量中的数组 $ this-> upload-> data（）;

All I needed to do was to store the array $this->upload->data(); in a variable for example

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

并从 $ image_info 访问图片属性。

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