图像不是笨

Question

正确上传我试图上传的图像，但只有内容插入到数据库中正确但图像路径或文件不上载这里我的代码，

我的观点post.php中文件代码：

<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> 

这里我控制器的welcome.php文件代码：

<?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 
}

我会尽力纠正你控制器。

<?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 
    } 
}
