在codeigniter中上传图片

Question

我想上传三张图片中的图片。我的文件夹结构如下： upload/large，upload/original，upload/thumb。 如何使用codeigniters的“上传”库将调整大小后的图像存储到这些文件夹中。

Answer 1

我与钠同意，你需要接受更多的答案。

然而，对于这样的问题： 它看起来对我像你其实只是上传到原来的文件夹，然后用这个复制的图像库，所以，请尝试以下操作：

$config['upload_path'] = './upload/original'; 
$config['allowed_types'] = 'gif|jpg|png'; 
$config['max_size'] = '100'; 
$config['max_width'] = '500'; 
$config['max_height'] = '300'; 
$this->load->library('upload', $config); 

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

$copies = array(
       array('dir' => 'upload/large', 'x' => 1000, 'y' => 600), //note: x&y could be replaced with a percentage or ratio etc. 
       array('dir' => 'upload/thumbnail', 'x' => 100, 'y' => 60) 
       ); 

foreach($copies as $copy) 
{ 
       $config['image_library'] = 'ImageMagick'; 
       $config['library_path'] = '/usr/bin/'; 
       $config['source_image'] = $upload_data['full_path']; 
       $config['new_image'] = $copy['dir'] . $upload_data['file_name']; 
       $config['maintain_ratio'] = TRUE; 
       $config['width'] = $copy['x']; 
       $config['height'] = $copy['y']; 
       $config['master_dim'] = 'width'; 
       $this->image_lib->initialize($config); 
       $this->image_lib->resize(); 
} 

希望这有助于！

您应该更改配置阵列中的“upload_path”值。

这是某种形式的代码，你可以使用：

$config['upload_path'] = './uploads/'; 

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