修改我的圖片上傳

Question

在目前這個時間點，我有一些代碼，執行以下操作：

我可以編輯，我可以添加一個房屋買賣是上傳/在編輯一個像這個特殊的房子，然後創建縮略圖，然後將原始文件名和縮略圖名稱保存到名爲imagename和imagethumb的數據庫字段中。

（注：添加和編輯seprate頁）

什麼我的想法是：

我將創建一個具有送入下拉菜單房屋的名稱的另一個頁面，以便當一個人選擇並且圖像被選擇，他們將上傳。

什麼我的問題是：

1. 我得到自己困惑，這將是修改我的數據庫，以使這種變化的最好辦法。

2. 我該如何修改我的php代碼來處理多個文件（如何處理多個圖像，然後通過圖像上傳調整大小等）什麼是最好的選擇？ - 在我的想法？

3. 我能舉一個我應該怎麼做的例子，我可以解決這個問題。

我已經包括了模型視圖和控制器（作爲一個例子）我加售，但我還需要編輯圖像各自的銷售。

Answer 1

爲了處理下拉列表中，我薄簡單的一個。但相關的多上傳的東西，你可以在你的視圖控制器使用類似...

<?php echo form_label('Image: ','userfile1');?> 
<?php echo form_upload('userfile1');?> 
<?php echo form_label('Image: ','userfile2');?> 
<?php echo form_upload('userfile2');?> 
<!-- and so on --> 
<span class="small">Required Field - 1MB Max Size</span> 

然後，你可以做這樣

//Set File Settings 
$config['upload_path'] = 'includes/uploads/sales/'; 
$config['allowed_types'] = 'jpg|png'; 
$config['remove_spaces'] = TRUE; 
$config['overwrite'] = TRUE; 
$config['max_size'] = '1024'; 
$config['max_width'] = '1024'; 
$config['max_height'] = '768'; 

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

// Validate files for upload section... 
$success = array(); 
$errors = array(); 
$updload_files = array(
     'userfile1' => $_FILES['userfile1'], 
     'userfile2' => $_FILES['userfile2'], 
     // You can add more 
     ); 

foreach($updload_files as $field => $updload_file) 
{ 
    // Only process submitted file 
    if($updload_file['error'] == 0) 
    { 
     // If there is an error, save it to error var 
     if(! $this->upload->do_upload($field)) 
     { 
      $errors[] = 'Failed to upload '.$field; 
     } 

     // Use this to get the new file info if you need to insert it in a database 
     $success[] = array('Success to upload '.$field => $this->upload->data()); 
    } 
    else 
    { 
     $errors[] = $field . ' contain no data'; 
    } 
} 
// Heres you could gettin know whats happen 
var_dump($errors); 
var_dump($success);
