$profile_image = 'profile_image'; 
$this->load->library('custom_upload_lib'); 
//get file extension 
$fileExtension = ""; 
if($_FILES["profile_image"]["name"]): 
    // "profile_image" is the form input field name 
    $path_info = pathinfo($_FILES["profile_image"]["name"]); 
    $fileExtension = $path_info['extension']; 
endif; 
$upload_path  = './uploads/profile_image/'; 
$allowed_types = 'GIF|gif|PNG|png|jpg|JPEG|jpeg'; 
$max_size   = 2048; 
$encrypt   = false; 
$saved_file_name = "profile_".rand(2,8) 
        .strtotime(date('Y-m-d H:i:s')).'.'.$fileExtension; 
//$saved_file_name=$_FILES["profile_image"]["name"]; 
$overwrite  = false; 
$upload_control_name = $profile_image ; 
$filePath   = ""; 
$uploadname   = ""; 
if($fileExtension != "") 
{ 
    $upload_data = $this->custom_upload_lib->configure_upload($upload_path, 
     $allowed_types,$max_size,$encrypt,$saved_file_name, 
     $overwrite,$upload_control_name); 
    if(is_array($upload_data)) 
    { 
     $filePath   = $upload_data['full_path']; 
     $uploadname  = 'profile_image/'.$upload_data['file_name']; 
     $temp_upload_name = $upload_data['file_name']; 

     $width = 90; 
     $height = 90; 
     $this->load->library('resize_lib'); 
     $resize = $this->resize_lib->_resizeImage( 
         $filePath ,$temp_upload_name, $width, $height); 

     if(!$resize) 
     { 
      $message = $resize; 
      $this->session->set_flashdata('message', $message); 
      redirect(site_url('admin/preacher')); 
     } 
    } 
    else 
    { 
     $message = $upload_data; 
     $this->session->set_flashdata('message', $message); 
     redirect(site_url('admin/preacher')); 
    } 
}

小心解释问题？如果你说“不起作用”，我们只能回答“代码错误”。 – 2012-01-03 10:08:15

是的，请说明错误是什么，如何重现问题！你也可以把resize_lib的代码放在pastebin中，并在这里给出链接。 – HungryCoder 2012-01-03 10:41:48

用于在CI中调整大小的默认库是[Image Manipulation Class]（http://codeigniter.com/user_guide/libraries/image_lib.html）。如果您不使用该库，请让我们看看您选择的库的代码。 – swatkins 2012-01-03 14:54:08

您必须使用image_lib。使用下面的代码来调整图像大小

$config['image_library'] = 'gd2'; 
$config['source_image'] = $upload_path.$saved_file_name; 
$config['create_thumb'] = TRUE; 
$config['maintain_ratio'] = TRUE; 
$config['width']  = 90; 
$config['height'] = 90; 

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

$this->image_lib->resize();
