Question

我正在更新我网站的管理员端。

我目前设法包含一个添加页面，该页面上传到我的网站的数据库以显示内容。

在此页面中是图像上传按钮。

当我从此上传按钮中选择文件时，它会将图像保存到我的/ images文件夹中。

然而。当我在ipad上使用此功能上传图像时，它会将所有图像上传为image.jpg。

我现在需要的是：

我需要将上传的图片保存到品牌名称而不是原始上传的图片名称。因此，如果我上传“image.jpg”，然后输入APPLE作为品牌，我希望在我上传文件时将图像保存为apple.jpg。

我当前的add.php页面是这样的：

<?php

session_start();

include_once('../include/connection.php');

if (isset($_SESSION['logged_in'])){
  if (isset($_POST['title'], $_POST['content'])) {
        $title   = $_POST['title'];
        $content = nl2br($_POST['content']);
        if (!empty($_POST['image']))
        {
            $image = $_POST['image'];
        }
        else
        {
            $image = $_POST['imageupload'];

            if (isset($_FILES['imageupload']))
            {
              $errors = array();
              $allowed_ext = array('jpg', 'jpeg', 'png', 'gif');

              $file_name = $_FILES['imageupload'] ['name'];
              $file_ext = strtolower (end (explode ('.', $file_name)));
              $file_size = $_FILES['imageupload'] ['size'];
              $file_tmp = $_FILES['imageupload'] ['tmp_name'];

              if (in_array ($file_ext, $allowed_ext) === false) {
                     $errors[] = 'File extension not allowed';
              }

              if ($file_size > 2097152) {
                     $errors[] = 'File size must be under 2mb';
              }

              if (empty($errors)) {
                     if (move_uploaded_file($file_tmp, 'images/'.$file_name)) {
                           echo 'File uploaded';
                           $image = 'http://www.xclo.mobi/xclo2/admin/images/'.$file_name;
              }
              }else{
                    foreach ($errors as $error)
                    echo $error, '<br />';
              }

            }
        }
        $link     = $_POST['link'];
        $category = $_POST['category'];
        $brand    = $_POST['brand'];


if (empty($title) or empty($content)) {
         $error = 'All Fields Are Required!';

请有人帮忙吗？谢谢。

Answer 1

在上传过程中，您需要将文件名更改为您希望的文件名。

{
    $errors = array();
    $allowed_ext = array('jpg', 'jpeg', 'png', 'gif');

    $file_name = $_FILES['imageupload'] ['name'];
    $file_ext = strtolower (end (explode ('.', $file_name)));
    $file_size = $_FILES['imageupload'] ['size'];
    $file_tmp = $_FILES['imageupload'] ['tmp_name'];

    $file_name = $_POST['brand'].'.'.$file_ext;

Answer 2

我使用了这段代码，它对我来说很好用。

谢谢你。

$brand = $_POST['brand']; // Put this up by where you define $title


$up_file = $brand.'.'.$file_ext;
if (move_uploaded_file($file_tmp, 'images/'.$up_file)) {
echo 'File uploaded';
$image = 'www.mysite.com/images/'.$up_file;
}

请1up ......

Answer 3

1）获取图片扩展名

$ ext = pathinfo（$ filename，PATHINFO_EXTENSION）;

2）通过concatenatin品牌名称上传您的文件＆amp;扩展

move_uploaded_file（$ _ FILES ['imageupload'] ['tmp_name']，$ _POST ['your_brand']。'。'。$ ext）;

上传时更改名称
