我不确定这段代码有什么问题，所以我希望能提供一些有用的输入。

问题

它不会获取我上传的文件的名称，也不会实际将其上传到定义的目录中。

PHP 代码

<? include("header.php"); 
include("sidebar.php");
?>        



    <h2>Add Raffle</h2> 

 <?
$name = asql($_POST['name']);
$type = asql($_POST['prize']);
$min_points = asql($_POST['minp']);
$min_cash = asql($_POST['maxu']);
$cons = strtotime($_POST['cons']);
$cone = strtotime($_POST['cone']);


if($_POST['subm'])
{
if ($name == NULL OR $type == NULL OR $min_points == NULL OR $min_cash == NULL) {
print"Please Fill Out All Of The Required Fields<br /><a href='rafadd.php'><img src='img/green_arrow_left.png' alt='Go Back' /></a>"; include"footer.php";
exit();
}
if (!in_array($file['type'], array("image/gif", "image/jpeg", "image/png"))
           || $file['size'] > 20000)
  {
  if ($_FILES["file"]["error"] > 0)
    {
    echo "There was an error";
    }

我在另一个脚本中使用了文件上传片段，它上传完美，所以我不确定为什么它在这里不起作用。

在表单标签中添加 enctype="multipart/form-data"

<form action='' method='post'enctype="multipart/form-data">

<form action='' method='post'>

错了，应该是：

 <form action='' method='post' enctype='multipart/form-data'>

另外，使用<?php代替<?

PS我错过了设置 $file 的地方。

它看起来不像文件在任何地方被实例化。你的意思是：

if (!in_array($_FILES['file']['type'], array("image/gif", "image/jpeg", "image/png"))
       || $_FILES['file']['size'] > 20000)
