我有一个简单的问题。我通过PHP在特定会话目录中显示图像并删除它们,问题是,脚本删除所有图像而不仅仅是其中一个图像。这就是我正在做的事情:
PHP / HTML:
<ul class="image-list">
<?php
if ($_SESSION['curHotelId']) {
$count = 1;
foreach(glob('assets/php/upload/'.$_SESSION['curHotelId'].'/*') as $filename){
echo '<li id="del'.$count.'" class="image-list"><img src="'.$filename.'" width="50px" height="50px"/><p class="filename">' . basename($filename) . '</p> <a class="btn btn-mini btn-primary image-list" style="width: 50px; margin-top:-20px;" id="del'.$count.'" value="Delete">remove</a></li>' . "\n" . "<br>";
$count++;
}
}else {}
?>
</ul>
jQuery的:
$('ul li a.image-list').live('click', function() {
var answer = confirm('Are you sure you wish to delete this image?');
if (answer) {
$.post('assets/php/deletefile.php');
$(this).closest('.li').remove();
}
});
删除脚本:
<?php
session_start();
foreach(glob("upload/" . $_SESSION['curHotelId'] . "/" . '*.*') as $file)
if(is_file($file))
@unlink($file);
?>
一切都有帮助!
答案 0 :(得分:1)
仅删除当前会话文件夹中的一个(第一个)文件:
<?php
session_start();
$files = glob("upload/" . $_SESSION['curHotelId'] . "/" . '*.*');
if(is_file($files[0]))
@unlink($files[0]);
?>
