如何在codeigniter中上传2个单独的图像

如果你想要两个不同的文件按钮，你需要给它们不同的名称。

<form action="" enctype="multipart/form-data" method="post" accept-charset="utf-8">
<input type="file" name="userfile1" size="20">
<input type="file" name="userfile2" size="20">
<input type="submit" name="submit" value="upload">

然后你必须修改你的函数ddoo_upload()，如下所示：-

  function ddoo_upload($filename){
    $config['upload_path'] = './uploads/';
    $config['allowed_types'] = 'gif|jpg|png';
    $config['max_size'] = '100';
    $config['max_width']  = '1024';
    $config['max_height']  = '768';
    $this->load->library('upload', $config);
    if ( ! $this->upload->do_upload($filename)) {
        $error = array('error' => $this->upload->display_errors());
    return false;
    // $this->load->view('upload_form', $error);
    } else {
    $data = array('upload_data' => $this->upload->data());
    return true;
    //$this->load->view('upload_success', $data);
    }
}

注意：-我们将$filename作为变量传递，然后使用它上传不同的文件。

现在，在表单操作重定向的控制器中，您需要编写以下代码。

  if ($this->input->post('submit')){
    if (isset($_FILES['userfile1']) && $_FILES['userfile1']['name'] != ''){
        $file1 = $this->ddoo_upload('userfile1');
    }
        
    if (isset($_FILES['userfile2']) && $_FILES['userfile2']['name'] != ''){
        $file2 = $this->ddoo_upload('userfile2');
    }   
}

这是我申请在codeigniter 中上传两张图像的控制器代码

公共函数index（）｛

if($this->input->post('Submit')){
//-----------Image File Section Start Here -----------//
 $config['upload_path'] = './uploads/';   // Directory 
$config['allowed_types'] = 'jpg|jpeg|bmp|png';  //type of images allowed
$config['max_size'] = '30720';   //Max Size
$config['encrypt_name'] = TRUE;   // For unique image name at a time
$this->load->library('upload', $config);  //File Uploading library
$this->upload->do_upload('userfile');  // input name which have to upload 
$video_upload=$this->upload->data();   //variable which store the path
//--------------End of Image File  Section------------------------//

//---------Thumbnail Image Upload Section Start Here -----------//
$config2['upload_path'] = './thumb/';   // Directory 
$config2['allowed_types'] = 'jpg|jpeg|bmp|png'; //type of images allowed
$config2['max_size'] = '30720';   //Max Size
$config2['encrypt_name'] = TRUE;   // For unique image name at a time

$this->upload->initialize($config2); //we can not use upload library again and again it will not initialize again and again so thats why i have used initialize 
$this->upload->do_upload('txt_thumb');  // File Name
$thumbnail_upload=$this->upload->data(); // store the name of the file 
//--------End of Thumbnail Upload Section-----------//

    $date=date("d-m-Y");  // Store current date in variable 
   // Here the database query to insert
    $data = array(
    'parent_id'=> $this->input->post('txt_parent'),
    'cat_id' => $this->input->post('txt_category'),
    'title'=> $this->input->post('txt_title'),
    'status' => $this->input->post('txt_status'),
    'featured' => $thumbnail_upload['file_name'],
    'image' => $video_upload['file_name'],
    'time'=>$date
    );
       $sql_ins= $this->Insimage->insertimage($data);
       if($sql_ins)
       {
           $data['Success'] = "Image has been succesfully inserted!!";
       }

}

这个代码肯定能上传2张图片享受吧！！！：-）

<form action="http://localhost/cod_login/club/test2" enctype="multipart/form-data" method="post" accept-charset="utf-8">

<input type="file" name="userfile" size="20" multiple="">
<input type="submit" name="submit" value="upload">
</form>

1-在控制器中创建image_uploader

function image_uploader($filename){
  $config['upload_path'] = './assets/uploads/setting/';
  $config['allowed_types'] = 'gif|jpg|png';
  $config['max_size'] = '100';
  $config['max_width']  = '2000';
  $config['max_height']  = '2000';
  $this->load->library('upload', $config);
  if ( ! $this->upload->do_upload($filename)) {
  $error = array('error' => $this->upload->display_errors());
  } else {
  $data_foto = $this->upload->data();
  return $data_foto['file_name'];
}

如果上传成功，此函数将返回图像文件的名称

2-调用其他功能中的image_uploader（视图中的表单操作）

public function slideroneupload() {
  $this->site_security->_make_sure_is_admin();
  $data = $this->input->post();
  $sliderimage = $this->image_uploader('image');
  $thumbimage = $this->image_uploader('thumb');
  // save all data to database 
  .
  .
  .
}
