藉助複選框刪除所選圖像

這是用戶可以編輯其上傳圖像的頁面。每張圖片附近都有一個複選框。我想在用戶單擊「刪除選定圖像」按鈕（每個複選框包含圖像名稱作爲值）後刪除所選圖像。我怎樣才能做到這一點？藉助複選框刪除所選圖像

<?php 
    session_start(); 
    //////////////if user already logged in go to login.php///////// 
    if (isset($_SESSION['email'])&& isset($_SESSION['password'])) 
    { 
    } else{header("Location: login.php"); } 

     include('includes/config.php'); 


     if (isset($_POST['esubmit']) ){ 

     $checkbox=$_POST['delete']; 
     echo $checkbox; 

     }//main one 



    if (isset($_POST['esubmit']) ){ 

    } else {  $clickeditid=$_GET["id"]; 
     $_SESSION['eid']= $clickeditid ; 
     }

你必須創建一個表單提交的檢查複選框中的數據和湯治療用PHP代碼submited結果：如果你希望把PHP代碼相同的頁面上，你可以檢查在POST變量中有任何數據並創建一個SQL查詢來刪除相應的圖片。

您可以在這裏找到一個很好的記錄教程：http://sharemyphp.wordpress.com/2009/12/21/ajax-jquery-php-multiple-delete-item-with-check-box/

我用下面的代碼在我的管理面板中刪除圖像。我將該文件保存爲deletephoto.php。請注意，此腳本無需登錄即可使用。您需要進行一些更改以適合您的使用情況

<form method="post" action="deletepho.php"> 
<center> 
<input type="submit" value="Delete" name="Delete"> 
</center> 
<?php 
\\lets assign the folder name in $title 
\\You can assign any name 
$title= "test"; 
\*$directory corresponds to whole path. Edit to your preference. (i assume u store your 
images in directory named "images") */  
$directory = "$title/images"; 
\\The array specifies the format of the files 
$allowed_types=array('jpg','jpeg','gif','png'); 
$file_parts=array(); 
$ext=''; 
$title=''; 
$i=0; 

$dir_handle = @opendir($directory) or die("There is an error with your image directory!"); 

while ($file = readdir($dir_handle)) 
{ 
    if($file=='.' || $file == '..') continue; 

    $file_parts = explode('.',$file); 
    $ext = strtolower(array_pop($file_parts)); 

    $title = implode('.',$file_parts); 
    $title = htmlspecialchars($title); 

    $nomargin=''; 

    if(in_array($ext,$allowed_types)) 
    { 
     if(($i+1)%4==0) 
     $nomargin='nomargin'; 
     echo' 
     <div id="picture"> 
     <img src="'.$directory.'/'.$file.'" width="150" height="150"><br> 
     Select <input type="checkbox" value="'.$directory.'/'.$file.'" name="imgfile[]"> 

\* I specified input name as an array . So that we can store in an array and delete it.*/ 
      </div>'; 
      } 
      $i++; 
     } 

    closedir($dir_handle); 
    \\Now we have the list of images within form elements 
    ?> 
    </form>

現在，您可以使用實際的代碼來刪除照片。我將它保存爲deletepho.php。

$file = $_REQUEST['imgfile']; 
$num_files=count($file); 
for($i=0;$i<$num_files;$i++) 
{ 
unlink ("$file[$i]"); 
} 
echo "Images successfully deleted.Go <a href='deletephoto.php'>back</a>";
