错误说：
这是我的查看代码：
i am learning how to upload an image with codeigniter, and i got an error permission denied when i click on the upload without any image, it works well if i select an image. i just hoped it will show my message it is: Please upload an Images,can you have a look on my code and help me figure down my problem. the error says: This is my view code:
<head>
<title>CI upload images</title>
<meta charset="UTF-8">
</head>
<body>
<div id="gallery">
<?php if(isset($images) && count($images)):
foreach ($images as $image): ?>
<div class="thumb">
<a href="<?php echo $image['url']; ?>">
<img src="<?php echo $image['thumb_url']; ?>"/>
</a>
</div>
?>
<?php endforeach; else: ?>
<div id="blank_gallery">Please upload an Images</div>
<?php endif; ?>
</div>
<div id="upload">
<?php
echo form_open_multipart('gallery');
echo form_upload('userfile');
echo form_submit('upload', 'Upload');
echo form_close();
?>
</div>
</body>
这是我的控制器代码：
class Gallery extends CI_Controller{
function index(){
$this->load->model('Gallery_model');
if($this->input->post('upload')){
$this->Gallery_model->do_upload();
}
$data['images'] = $this->Gallery_model->get_images();
$this->load->view('gallery_view', $data);
}
}
p>
and here is my model
class Gallery_model extends CI_Model{
var $gallery_path;
var $gallery_path_url;
function __construct(){
parent::__construct();
$this->gallery_path = realpath(APPPATH . '../images');
$this->gallery_path_url = base_url().'images/';
}
function do_upload(){
$config = array(
'allowed_types' => 'jpg|jpeg|gif|png',
'upload_path' => $this->gallery_path,
'max_size' => 2000
);
$this->load->library('upload', $config);
$this->upload->do_upload();
$image_data = $this->upload->data();
$config = array(
'source_image' => $image_data['full_path'],
'new_image' => $this->gallery_path . '/thumbs',
'maintain_ration' => true,
'width' => 150,
'height' => 100
);
$this->load->library('image_lib', $config);
$this->image_lib->resize();
}
function get_images(){
$files = scandir($this->gallery_path);
$files = array_diff($files, array('.','..','thumbs'));
$images = array();
foreach ($files as $files) {
$images []= array(
'url'=> $this->gallery_path_url . $files,
'thumb_url' => $this->gallery_path_url . 'thumbs/' . $files
);
}
return $images;
}
}
您能帮忙吗？
推荐答案
'new_image' => $this->gallery_path . '/thumbs',
设置目标映像名称/路径。创建映像副本时，将使用此首选项。 路径必须是相对或绝对的服务器路径，而不是网址。
Sets the destination image name/path. You'll use this preference when creating an image copy. The path must be a relative or absolute server path, not a URL.
您将new_image设置为文件夹，而不是文件名。使它像$ this-> gallery_path。 '/thumbs/my_new_file.ext'
you set new_image as folder, not filename. make it like $this->gallery_path . '/thumbs/my_new_file.ext'
