圖像不是笨

Question

正確上傳我試圖上傳的圖像，但只有內容插入到數據庫中正確但圖像路徑或文件不上載這裏我的代碼，

我的觀點post.php中文件代碼：

<form action="" method="post" enctype="multipart/form-data"> 
     <table> 
       <tr> 
        <td>Book Title</td> 
        <td><input type="text" name="title" /></td> 
       </tr> 
       <tr> 
        <td>Book Author</td> 
        <td><input type="text" name="author" /></td> 
       </tr> 
       <tr> 
        <td>Book Image</td> 
        <td><input type="file" name="image" /></td> 
       </tr> 

       <tr> 
        <td>Book Description</td> 
        <td><input type="text" name="content" /></td> 
       </tr> 
       <tr> 
        <td><input type="submit" name="submit" /></td> 
       </tr> 
     </table> 
     </form> 

這裏我控制器的welcome.php文件代碼：

<?php if (! defined('BASEPATH')) exit('No direct script access allowed'); 

class Welcome extends CI_Controller { 
    public function index() 
      {  
     if (!empty($_POST)) { 
      $title = $this->input->post('title'); 
      $author = $this->input->post('author'); 
      $image['upload_path'] = './images/'.$_FILES['image']['tmp_name']; 
      $image['allowed_types'] = 'gif|jpg|png'; 
      $image['max_size'] = '200'; 
      $image['max_width'] = '2000'; 
      $image['max_height'] = '1500'; 
      $this->load->library('upload', $image); 
      $content = $this->input->post('content'); 
      $date = date('Y-m-d'); 
      if ($title && $author && $image && $content) { 
       $this->load->model('insert'); 
       $data = array(
       //field list 
        'book_title' => $title, 
        'book_author' => $author, 
        'book_image' => $image['upload_path'], 
        'book_content' => $content, 
        'date' => $date 
       ); 
       $id = $this->insert->form($data); 
      } 

     } 
     $this->load->view('insert/post');      
      } 
} 

Answer 1

try this code it will help you 
$filename='image'; //Your image name 
$title = $this->input->post('title'); 
$content = $this->input->post('content'); 
$author = $this->input->post('author'); 
$image['upload_path'] = '/images/'; 
$image['allowed_types'] = 'gif|jpg|png'; 
$image['max_size'] = '1024*4'; 
$image['max_width'] = '2000'; 
$image['max_height'] = '1500'; 
$image['encrypt_name']=true; 
$this->load->library('upload', $image); 
$date = date('Y-m-d'); 
if ($title && $author && $image && $content) { 
$this->load->model('insert'); 
$data=$this->upload->data(); 
$data1 = array(
//field list 
'book_title' => $title, 
'book_author' => $author, 
'book_content' => $content, 
'date' => $date 
); 
$id = $this->insert->form($data['file_name'],$data1); 

$this->load->view('insert/post');      
} 

Model Code: 
public function insert_file($filename,$title) 
{ 
    // your insert query 
}

我會盡力糾正你控制器。

<?php if (! defined('BASEPATH')) exit('No direct script access allowed'); 

class Welcome extends CI_Controller { 

    public function index() 
    { 
     if (!empty($_POST)) { 
      $title = $this->input->post('title'); 
      $author = $this->input->post('author'); 
      $config['upload_path'] = './images/'; //only upload path 
      $config['allowed_types'] = 'gif|jpg|png'; 
      $config['max_size'] = '200'; 
      $config['max_width'] = '2000'; 
      $config['max_height'] = '1500'; 
      $this->load->library('upload', $config); //upload lib config not image 
      $content = $this->input->post('content'); 
      $date = date('Y-m-d'); 
      if ($title && $author && $image && $content) { 
       if (! $this->upload->do_upload('image')) { //your file input name 
        $view_data['error'] = array('error' => $this->upload->display_errors()); //pass errror to view in case of error 
       } else { 
        $upload_data = $this->upload->data(); 
        $view_data['upload_data'] = $upload_data; //to pass upload data to view 

        $this->load->model('insert'); 
        $data = array(
         //field list 
         'book_title' => $title, 
         'book_author' => $author, 
         'book_image' => $upload_data['full_path'], //read the user_guide to see other posibilities 
         'book_content' => $content, 
         'date' => $date 
        ); 
        $id = $this->insert->form($data); 
       } 
      } 
     } 
     $this->load->view('insert/post', $view_data); //pass upload data or error 
    } 
}
