데이터베이스에 이미지를 업로드하는 방법 폴더에 저장 하시겠습니까?

Question

저는 CI가 처음입니다. CI 2.0 이미지 업로드를위한 자습서를 제공 할 수있는 사람이 있습니까? 제품 코드 내가 자산 folder.My 테이블 이름의 폴더 Product_image이 tbl_product 누군 컨트롤러 페이지인지 확인해야된다 :

내 모델 페이지가 product_model입니다 :

} 

function listAllProduct() {

    //$query = $this->db->query("select * from tbl_product");

    $this->db->where('prod_id', $prod_id); 
    $query = $this->db->get('tbl_product');

내가 그에게 감사 해요/그녀의 나에게 실수 n 개의 오류를 확인하여이 오류 코드에 대한 솔루션을 제공?

Answer 1

1 : 형태로 파일을 업로드 할 때 속성 open_multipart을 사용해야합니다 :

<?php echo form_open_multipart('product/addproduct');?> 

2 : 양식 유효성 검사에서 파일 형식 attrribute를 벗어이 삭제 :

$this->form_validation->set_rules('prod_image', 'Picture', 'required|xss_clean'); 

3 :

,691,363 : 폴더에 파일을 저장하는 데 사용합니다210

$config['upload_path'] = './asset/Product_image/'; //The path where the image will be save 
$config['allowed_types'] = 'gif|jpg|png'; //Images extensions accepted 
$config['max_size'] = '2048'; //The max size of the image in kb's 
$config['max_width'] = '1024'; //The max of the images width in px 
$config['max_height'] = '768'; //The max of the images height in px 
$config['overwrite'] = TRUE; //If exists an image with the same name it will overwrite. Set to false if don't want to overwrite 
$this->load->library('upload', $config); //Load the upload CI library 
if (!$this->upload->do_upload('userfile')){ 
    $uploadError = array('upload_error' => $this->upload->display_errors()); 
    $this->set_flashdata('uploadError', $uploadError, $urlYouWantToReturn); //If for some reason the upload could not be done, returns the error in a flashdata and redirect to the page you specify in $urlYouWantToReturn 
    exit; 
} 

4 : 그 다음에는 파일 이름을 가져 데이터베이스에 파일 참조를 저장합니다. 바로 아래에 넣어 :

$file_info = $this->upload->data('userfile'); 
$file_name = $file_info['file_name']; //Now you got the file name in the $file_name var. Use it to record in db. 
//You can assign it to your data array to pass to your update_product function.

이 난, 내 CI 프로젝트에 사용이 도움이되기를 바랍니다 것입니다!

Answer 2

형식으로 이미지를 업로드하려면 enctype 속성을 지정하십시오.

<?php echo form_open_multipart('product/addproduct');?> 
     <input type="file" name="userfile" size="20" /> 
     <input type="submit" value="Submit"> 
<?php echo form_close();?> 

또한 CodeIgniter에는 설명서에있는 몇 가지 도우미 클래스가 있습니다. 여기에 하나입니다 :
