Question

我在我的应用程序视图中有：

＆＃13;

<div class="form-group">
  <label class="col-md-4 control-label" for="content_textarea">Content</label>
  <div class="col-md-4">
    <textarea class="form-control" id="content_textarea" name="ad_news_content"></textarea>
  </div>
</div>
<!-- Select Basic -->
<div class="form-group">
  <label class="col-md-4 control-label" for="news_category">Category</label>
  <div class="col-md-4">
    <select id="news_category" name="ad_news_category"  class="form-control">
      <?php
      foreach ($news_category_data as $ncat ) {?>
        <option
           value="<?php echo $ncat->nc_id ?>"><?php echo $ncat->nc_id ," - ", $ncat->news_category_name ?>
         </option>
      <?php } ?>
    </select>
  </div>
</div>
<div class="form-group">
  <label class="col-md-4 control-label" for="news_create_date">Date</label>
  <div class=" col-md-5">
                  <input  type="text" placeholder="click to show datepicker"  id="datepic">
              </div>
</div>
<!-- main image upload -->
</div>
<div class="form-group">
  <label class="col-md-4 control-label" for="news_upload_img">Main Image</label>
  <div class=" col-md-5">
<input type="file" name="userfile" size="20" />

              </div>
</div>
<!-- end of main image upload -->


<!-- Button (Double) -->

<div class="form-group">
  <label class="col-md-4 control-label" for="edit_btn"></label>
  <div class="col-md-8">
    <button  id="edit_btn" name="add_btn" class="btn btn-primary"
    formaction="<?php echo base_url() ."admin/news/insertNews"?>">Update</button>

＆＃13;

在我的控制器中，我有插入数据库和上传图像的功能

    public function insertNews()
{
            $config = array(
                'upload_path'   => './uploads/up_news',
                'allowed_types' => 'gif|jpg|png',
                'max_size'      => '100',
                'max_width'     => '1024',
                'max_height'    => '768',
                'encrypt_name'  => true,
            );

            $this->load->library('upload', $config);
                    $this->upload->initialize($config);
                $upload_data = $this->upload->data();
                $data_ary = array(
                    'title'     => $upload_data['client_name'],
                    'file'      => $upload_data['file_name'],
                    'width'     => $upload_data['image_width'],
                    'height'    => $upload_data['image_height'],
                    'type'      => $upload_data['image_type'],
                    'size'      => $upload_data['file_size'],
                                    'path'          => $upload_data['full_path'],
                    'date'      => time(),
                );
                $data = array('upload_data' => $upload_data);
            $this->load->model('newsModel');
    $ad_ne_data = array(
    'titel' => $this->input->post('ad_news_title') ,
    'content' => $this->input->post('ad_news_content') ,
    'news_category_id' => $this->input->post('ad_news_category') ,
    'img_url' => $data_ary['path']."".$data_ary['file'],
    'created_at' => date("Y-m-d")
);

    $this->newsModel->addNews($ad_ne_data);
}

代码运行正常，但图像未上传，数据库中只插入上传路径而没有图像名称而不是完整路径所以你可以纠正我的错误或者举例说明上传图片与其他字段，但每张图片都有像upload_news中的新闻，upload_post中的帖子等文章文件夹

Answer 1

您错过定义要上传的文件的代码中有一个简单的错误

从

更改您的代码

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

到

$upload_data = $this->upload->do_upload('userfile'); //added do_upload('userfile') your input file name

Answer 2

当您需要上传图片时，需要使用do_upload()我建议您使用form_helper form_open_multipart

class Example extends CI_Controller {

public function __construct() {

    parent::__construct();

    $this->load->library('form_validation');
    $this->load->helper('form');

}

public function index() {

    $data['title'] = 'Ad';

    $this->form_validation->set_rules('ad_news_title', 'Ad Title', 'required');
    $this->form_validation->set_rules('ad_news_content', 'Content', 'callback_insertNews');

    if ($this->form_validation->run() == FALSE) {

        $this->load->view('your_view', $data);

    } else {

        redirect('success_controller');
    }

}

public function insertNews() {
     $config = array(
                'upload_path'   => './uploads/up_news',
                'allowed_types' => 'gif|jpg|png',
                'max_size'      => '100',
                'max_width'     => '1024',
                'max_height'    => '768',
                'encrypt_name'  => true,
     );

    $this->load->library('upload', $config);

    if ($this->upload->do_upload('userfile')) {

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

    $data_ary = array(
    'title'     => $upload_data['client_name'],
    'file'      => $upload_data['file_name'],
    'width'     => $upload_data['image_width'],
    'height'    => $upload_data['image_height'],
    'type'      => $upload_data['image_type'],
    'size'      => $upload_data['file_size'],
    'path'          => $upload_data['full_path'],
    'date'      => time(),
    );

    $data = array('upload_data' => $data_ary);

    $this->load->model('newsModel');

    $ad_ne_data = array(
        'titel' => $this->input->post('ad_news_title') ,
        'content' => $this->input->post('ad_news_content') ,
        'news_category_id' => $this->input->post('ad_news_category') ,
        'img_url' => $data_ary['path']."".$data_ary['file'],
        'created_at' => date("Y-m-d")
    );

    $this->newsModel->addNews($ad_ne_data);

    } else {

       // Some Error

       $this->form_validation_set_message('insertNews', $this->upload->display_errors());

       return FALSE;

    }

}


}

使用回调的第二个想法

文件名：Example.php

<?php echo form_open_multipart('example/insertNews');?>

// The rest of the form content goes here

<?php echo form_close();?>
