问题描述
我有一个页面，我可以上传一些图像，查看表格中加载的图像列表。我想添加从服务器删除列表中的一个图像的机会。我试过但是这段代码中的某些东西不起作用。有帮助吗？
I have a page where I can upload some images, see the list of images loaded in a table. I want to add the chance to delete one of the images in the list from the server. I tried but something in this code is not working. Any help?
<html>
<body>
<form action="" method="post" enctype="multipart/form-data">
Select a photo to upload:
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Load" name="submit">
</form>
<?php
$dir = 'up/';
$files = scandir($dir);
$maxnum = count($files);
?>
<table class="thumbnail">
<?php $i = 2;
for ($j = 0; $j < $maxnum; $j++) {
echo '<tr>';
$k = $i + 5;
for ($i; $i < $k; $i++) {
If ($i == $maxnum) { break; }
echo '<td><a href="'.$dir.$files{$i}.'"><img src="'.$dir.$files{$i}.'"></a> </td>';
if (isset($_GET['delete']))
{
unlink($_GET['delete']);
$_SESSION['delete'] = $_GET['delete'];
unset($_GET['delete']);
$url = $_SERVER['SCRIPT_NAME'].http_build_query($_GET);
header("Refresh:0; url=".$url);
}
?>
<a href='index.php?delete=up/<?php echo $key?>' id="button">Delete now</a>
}
echo "</tr>";
} ?>
</table>
</div>
</body>
</html>
<?php
if (isset($_POST['submit']))
{
echo '<center><h1>succesfully loaded!</h1></center>';
$structure = 'up/';
$target_file = $structure.basename($_FILES["fileToUpload"]["name"]);
move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file);
}
?>
推荐答案
已完成的错误：
-
最后没有关闭循环
}}
未在锚标记中提供正确的文件路径 $ dir。$ files {$ i} 。 / p>
Not giving the proper file path $dir.$files{$i} in the anchor tag.
这是评估
以下是代码：
<html>
<body>
<form action="" method="post" enctype="multipart/form-data">
Select a photo to upload:
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Load" name="submit">
</form>
<?php
$dir = 'up/';
$files = scandir($dir);
$maxnum = count($files);
?>
<table class="thumbnail">
<?php $i = 2;
for ($j = 0; $j < $maxnum; $j++) {
echo '<tr>';
$k = $i + 5;
for ($i; $i < $k; $i++) {
If ($i == $maxnum) { break; }
echo '<td><br><a href="'.$dir.$files{$i}.'"><img src="'.$dir.$files{$i}.'" height="50" width="50"></a> </td>';
if (isset($_GET['delete']))
{
unlink($_GET['delete']);
$_SESSION['delete'] = $_GET['delete'];
unset($_GET['delete']);
$url = $_SERVER['SCRIPT_NAME'].http_build_query($_GET);
header("Refresh:0; url=".$url);
}
?>
<a href='index.php?delete=<?php echo $dir.$files{$i}?>' id="button">Delete now</a>
</table>
</div>
</body>
</html>
<?php
if (isset($_POST['submit']))
{
echo '<center><h1>succesfully loaded!</h1></center>';
$structure = 'up/';
$target_file = $structure.basename($_FILES["fileToUpload"]["name"]);
move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file);
}
}}
?>
注意：
第一个锚标记可能会看左对齐。这只是一个设计问题;）
The first anchor tag might look at left aligned. It's just a design issue ;)
