我正在使用以下腳本上傳圖像。這裏是鏈接:http://filer.grandesign.md/如何使用jQuery/Ajax/PHP刪除上傳的圖片?
使用此腳本它允許上傳圖像後預覽。像波紋管圖像:
你可以看到,它也允許刪除的圖像- 見紅桶圖標
什麼我現在做:
當我上傳圖像我重命名上傳的圖像並將其保存到數據庫。
的代碼波紋管:
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 : ' . $handle->error;
echo 'Error';
}
}
}
我需要什麼:
現在我要刪除我上傳的圖片。但這裏是這是一個問題:在默認情況下此腳本使用下面的PHP行刪除上傳的圖片:
<?php
if(isset($_POST['file'])){
$file = 'images/menu_images/' . $_POST['file'];
if(file_exists($file)){
unlink($file);
}
}
?>
但我不能刪除它,因爲當我上傳圖片到文件夾(images/menu_images/
)我將其重命名爲類似於:abedkd12415775554.jpg
我的問題是如何使用此腳本刪除上傳的圖像?
