我用php制作了一个相册。
我能够上传图像并显示图像列表。但我想添加一个删除按钮，用户可以删除那里不需要的图像。但我没能添加这个按钮工作。
谁来帮忙修理一下?
这是我在GitHub上的代码: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';
}
}
}
?>

hello，只需将提交输入更改为:
<input type="submit" name="delete" value="<?php echo $photoList[$x] ?>">
，然后检查该值:
<?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!";
}
}?>
