Question

我想在单击按钮上传多个文件，如果我将任何图像留空或者我没有上传任何内容，则应该有默认图像。但代码无法正常工作：

<?php

date_default_timezone_set('Asia/Calcutta');
$date = date('Y-m-d');

$s1=$_FILES['image']['name'];
$s2=$_FILES['image1']['name'];
$s3=$_FILES['image2']['name'];
$s4=$_FILES['image3']['name'];
$s5=$_FILES['image4']['name'];
$s6=$_FILES['image5']['name'];
$s7=$_FILES['image6']['name'];
$s8=$_FILES['image7']['name'];
$s9=$_FILES['image8']['name'];
$s10=$_FILES['image9']['name'];

$path="images/".$s1;
$path1="images/".$s2;
$path2="images/".$s3;
$path3="images/".$s4;
$path4="images/".$s5;
$path5="images/".$s6;
$path6="images/".$s7;
$path7="images/".$s8;
$path8="images/".$s9;
$path9="images/".$s10;

move_uploaded_file($_FILES['image']['tmp_name'],$path);

页面是什么样的？您可能需要发布更多信息（实际输出，来自服务器的任何错误消息，如果实际插入了行等），但如果页面为空白，我猜这可能是因为您的$s1到$s9变量实际上并不等于＆＃39;＆＃39;。尝试echo $s1;，看看当该字段为空时输出是什么

上传多个文件，如果我将任何图片留空或者不上传任何内容，则应该有默认图片
