如何在我的照片庫添加刪除php腳本

我用php製作了一個照片庫。
我可以製作上傳圖片並顯示圖片列表。但我想添加一個刪除按鈕，用戶可以在那裏刪除不需要的圖像。但我沒有添加這個按鈕的工作。如何在我的照片庫添加刪除php腳本

有人請幫忙解決嗎？

這是我在GitHub代碼：https://github.com/sagar290/photo_gallerey/blob/6cad3743e735ea109723de7e14d5477bff1e964b/gallery.php

<?php 

if (isset($_FILES["file"]["name"])) { 
    $name = $_FILES['file']['name']; 
    //$size = $_FILES['file']['size']; 
    //$extention = $type; 
    $type = strtolower($_FILES['file']['type']); 
    $tmp_name = $_FILES['file']['tmp_name']; 


    if (isset($name)) { 
    if (!empty($name)) { 
     if (($type=='image/jpg')||($type=='image/jpeg')||($type=='image/gif')) { 
     $location = 'photos/'; 

     if(move_uploaded_file($tmp_name, 'photos/'.$name)) { 
      echo $name.' is uploaded'; 

     } 
     }else { 
     echo 'file must be jpg or jpeg '; 
     } 


    }else { 
     echo 'please choose a file'; 
    } 
    } 
} 

?>

我可以」 t在那裏看到任何試圖刪除圖像的代碼 – Popnoodles

我明白了。它不告訴PHP要刪除哪個圖像。有人提供了一個答案無論如何 – Popnoodles

你好只是改變你的提交輸入：

<input type="submit" name="delete" value="<?php echo $photoList[$x] ?>">

，然後再檢查該值：

<?php if(isset($_POST['delete']) && !empty($_POST['delete'])){ 
    //find the file 
    $file = 'photos/'.$_POST['delete']; 
    if(is_file($file)){ 
     unlink($file); 
    }else{ 
     echo $_POST['delete']." has not been found!"; 
    } 
}?>

你錯過了所有的單引號 – Grork

tks，複製粘貼會這樣做給你，輸入錯誤一次.... –

它仍然無法正常工作，我不能刪除圖像:( –
