我想知道是否有人能夠幫助我。通過單選按鈕刪除圖像
我把下面的腳本放在一起,創建一個圖片庫。
<?php
if (isset($_POST['del']))
$originalname = intval($_POST['del']);
$file = 'UploadedFiles/' . $_SESSION['username'] . '/' . $_SESSION['locationid'] . '/' '$originalname';
if (!unlink($file))
{
echo ("Error deleting $file");
}
else
{
echo ("Deleted $file");
}
?>
<?php
$galleryPath = 'UploadedFiles/' . $_SESSION['username'] . '/' . $_SESSION['locationid'] . '/';
$thumbnailsPath = $galleryPath . 'Thumbnails/';
$absGalleryPath = realpath($galleryPath) . DIRECTORY_SEPARATOR;
$descriptions = new DOMDocument('1.0');
$descriptions->load($absGalleryPath . 'files.xml');
?>

針對每個圖像,並且出現在這行我的代碼:alt="<?php echo $name; ?>" src="<?php echo $thumbnail; ?>" /></a><?php echo "<input type='radio' name='del' value='{$originalname}' />"?></li>
我添加了一個單選按鈕。
當單選按鈕被選擇,並且被點擊「刪除選擇的圖像」按鈕我想圖像以在該文件路徑被刪除:
$galleryPath = 'UploadedFiles/' . $_SESSION['username'] . '/' . $_SESSION['locationid'] . '/';
和這裏:$thumbnailsPath = $galleryPath . 'Thumbnails/';
I」在PHP中並不是很出色,但我做了一些研究,我相信我需要使用'unlink'命令。所以我想我會試着用最初的一個文件路徑來編寫這個程序。我可以選擇一個單選按鈕,並獲得正確的Dialog Confirmation
消息出現,但不幸的是它不會刪除圖像,我不確定問題出在哪裏。
我只是想知道是否有人可能不想看看這個請讓我知道我哪裏出了問題?
非常感謝和問候
嗨,感謝您花時間回覆。我遇到的問題是我沒有收到任何錯誤信息,這可能表明代碼,而不是權限問題是原因。但是因爲我對PHP有點新,所以我不確定我的代碼是否有問題。我真的很想確認,但我明白,這可能只是強大的,我的代碼是正確的?親切的問候 – IRHM 2012-04-25 15:32:04
這條線的語法是錯誤的,你錯過了加入最後兩個字符串的點: $ file ='UploadedFiles /'。 $ _SESSION ['username']。 '/'。 $ _SESSION ['locationid']。 '/''$ originalname'; vs $ file ='UploadedFiles /'。 $ _SESSION ['username']。 '/'。 $ _SESSION ['locationid']。 '/'。 '$ ORIGINALNAME'; 看到區別? – gcochard 2012-04-25 15:34:12
嗨@Greg,非常感謝。我明白你的意思。我會做出改變。親切的問候 – IRHM 2012-04-25 16:58:39
