圖像上傳與codeigniter

我想上傳一個圖像，並保存圖像完整路徑在我的圖像表，但我不知道如何得到它的完整路徑出$this->upload->data()陣列這是我的代碼如下。圖像上傳與codeigniter

//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()); 
}

你應該在轉儲被看到了$this->upload->data()以下數組：

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" 
)

所以，你可以簡單地使用類似：

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 
}

這甚至沒有顯示的東西！圖像上傳，但完整的路徑沒有顯示。 –

那麼，if語句的哪個部分最終結束了？ – simnom

if（$ uploaded_image = $ this-> upload-> do_upload（））{ //成功顯示圖片成功上傳的成功消息。回聲「圖片已被上傳：」; –

所有我需要做的是存儲陣列$this->upload->data();在一個變量例如

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

和$image_info變量我可以訪問像這樣的圖像屬性。

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