我正在使用以下脚本上传图片。这是链接:http://filer.grandesign.md/
使用此脚本上传图像后允许预览。像贝娄图像:
您可以看到,它还允许删除图像 - 查看红色桶图标
我现在在做什么:
当我上传图片时,我重命名了上传的图片并将其保存到数据库。
代码如下:
require_once('class.upload.php');
if(!isset($_FILES['files'])) {
die();
}
$files = array();
foreach ($_FILES['files'] as $k => $l) {
foreach ($l as $i => $v) {
if (!array_key_exists($i, $files))
$files[$i] = array();
$files[$i][$k] = $v;
}
}
foreach ($files as $file) {
$handle = new upload($file);
if ($handle->uploaded) {
$handle->file_new_name_body = 'mpic_list_'.uniqid('', true);
$menu_list_image = $handle->file_new_name_body;
$handle->image_resize = true;
$handle->image_ratio_crop = true;
$handle->image_x = 360;
$handle->image_y = 240;
$handle->process('images/menu_images/');
$handle->file_new_name_body = 'mpic_small_'.uniqid('', true);
$menu_small_image = $handle->file_new_name_body;
$handle->image_resize = true;
$handle->image_ratio_crop = true;
$handle->image_x = 100;
$handle->image_y = 65;
$handle->process('images/menu_images/');
$handle->file_new_name_body = 'mpic_large_'.uniqid('', true);
$menu_large_image = $handle->file_new_name_body;
$handle->image_resize = true;
$handle->image_ratio_crop = true;
$handle->image_x = 700;
$handle->image_y = 470;
$handle->process('images/menu_images/');
if ($handle->processed) {
$all_images = $menu_list_image . $menu_small_image . $menu_large_image;
$u_id = (int) $_SESSION['logged_user_id'];
if(!isset($_SESSION['last_id'])) {
// insert upload image section data...
$insert_menu_details = mysqli_query($conn, "INSERT INTO products (p_id) VALUES ('')");
$last_id = mysqli_insert_id($conn);
$insert_upload_image = mysqli_query($conn, "INSERT INTO product_images VALUES ('', '$menu_large_image', '$menu_list_image', '$menu_small_image', '$last_id', '$u_id')");
$_SESSION['last_id'] = $last_id;
} else {
// update upload image section data
$session_last_id = $_SESSION['last_id'];
$update_upload_image = mysqli_query($conn, "INSERT INTO product_images VALUES ('', '$menu_large_image', '$menu_list_image', '$menu_small_image', '$session_last_id', '$u_id')");
}
$handle->clean();
} else {
//echo 'error : ' . $handle->error;
echo 'Error';
}
}
}
我需要什么:
现在我要删除上传的图片。但是这里存在一个问题:默认情况下,此脚本使用以下PHP行删除上载的图像:
<?php
if(isset($_POST['file'])){
$file = 'images/menu_images/' . $_POST['file'];
if(file_exists($file)){
unlink($file);
}
}
?>
但是我无法将其删除,因为当我将图片上传到文件夹(images/menu_images/
)时,我将其重命名为:abedkd12415775554.jpg
我的问题如何使用此脚本删除上传的图片?

您需要返回从服务器脚本中生成的新图像名称,如
在循环中执行以在数据库中插入文件名 -
$array = array("oldName" => "newName");
echo json_encode($array);
如果您在javascript端使用某些逻辑来创建数组,也可以使用数字索引。
在javascript on delete选项中,您可以使用图像名称检索值,并可以执行删除。
