多文件上傳 - 如何整合所有上傳文件的縮略圖功能？

Question

這些都是我的代碼多個上傳文件..

請你能幫助我的代碼交換也有縮略圖整合

public function addimage($room_id) 
{ 

    $name_array = array(); 
    $count = count($_FILES['userfile']['size']); 
    foreach($_FILES as $key=>$value) 
    for($s=0; $s<=$count-1; $s++) { 
     $_FILES['userfile']['name']=$value['name'][$s]; 
     $_FILES['userfile']['type'] = $value['type'][$s]; 
     $_FILES['userfile']['tmp_name'] = $value['tmp_name'][$s]; 
     $_FILES['userfile']['error']  = $value['error'][$s]; 
     $_FILES['userfile']['size'] = $value['size'][$s]; 
     $config['upload_path'] = './uploads/'; 
     $config['allowed_types'] = 'gif|jpg|png|jpeg'; 
     //$config['encrypt_name'] = uniqid(date(1)); 
     // $config['max_size'] = '100'; 
     // $config['max_width'] = '1024'; 
     // $config['max_height'] = '768'; 
     $this->load->library('upload', $config); 
     $this->upload->do_upload(); 
     $data = $this->upload->data(); 
     $name_array[] = $data['file_name']; 
    } // end foreach 
    $names= array($name_array); 
    print_r($names); 


    exit();

你應該重新初始化圖像庫：

$this->load->library('image_lib'); 
$image_config = array(
'source_image'  => $image_data['full_path'], 
'new_image'   => $this->thumbs_path, 
'maintain_ratio' => true, 
'width'    => 36, 
'height'   => 36 
); 

$this->image_lib->clear(); 
$this->image_lib->initialize($image_config); 
$this->image_lib->resize();

這個怎麼樣？

public function addimage($room_id) 
{ 

    $this->load->library("image_lib"); 
    $name_array = array(); 
    $count = count($_FILES['userfile']['size']); 
    foreach($_FILES as $key=>$value) 
    for($s=0; $s<$count; $s++) { 
     $_FILES['userfile']['name']=$value['name'][$s]; 
     $_FILES['userfile']['type'] = $value['type'][$s]; 
     $_FILES['userfile']['tmp_name'] = $value['tmp_name'][$s]; 
     $_FILES['userfile']['error']  = $value['error'][$s]; 
     $_FILES['userfile']['size'] = $value['size'][$s]; 
     $config['upload_path'] = './uploads/'; 
     $config['allowed_types'] = 'gif|jpg|png|jpeg'; 
     //$config['encrypt_name'] = uniqid(date(1)); 
     // $config['max_size'] = '100'; 
     // $config['max_width'] = '1024'; 
     // $config['max_height'] = '768'; 
     $this->load->library('upload', $config); 
     $this->upload->do_upload(); 
     $data = $this->upload->data(); 
     $name_array[] = $data['file_name']; 

     //thumbnail creation 
     $config['image_library'] = 'gd2'; 
     $config['source_image'] = $data['file_name']; 
     $config['create_thumb'] = TRUE; 
     $config['maintain_ratio'] = TRUE; 
     $config['width']   = 200; 
     $config['height']  = 200; 
     $this->image_lib->initialize($config); 
     $this->image_lib->resize(); 



    } // end foreach 
    $names= array($name_array); 
    print_r($names); 


    exit(); 
}

由於我理解你的問題，我會向您推薦閱讀笨的圖像處理庫。

有略圖創建。您可以在成功上傳後使用返回的數據創建縮略圖。
