PHP文件上传失败

问题描述

$ b

 <？php $ b $由于某种原因，我的PDF上传表单失败了，我有这样的代码：
 b if（$ _ POST [submit] ==将PDF添加到Comm和特殊项目）
 {
 $ addsubp = $ _POST [addsubp]; 
 $ addsubp_name = $ _POST [addsubp_name]; 
 $ commuploadedfile = $ _FILES ['uploadedfile'] ['name']; 
 $ sqldoc =INSERT INTO projects_links（pid，display_name，link）VALUES（'。$ addsubp。'，'。。$ addsubp_name。'，'。。$ commuploadedfile。'）; 
 mysql_query（$ sqldoc）或die（mysql_error（））; 
回显< BR>; 
 $ target_path =D：\\Hosting\\\\\\\\\\\\\\\\\\\\\\\\\\' 
 $ target_path = $ target_path。 basename（$ _FILES ['uploadedfile'] ['name']）; 
 
 if（move_uploaded_file（$ _ FILES ['uploadedfile'] ['tmp_name']，$ target_path））{
 echo< br>文件。 basename（$ _FILES ['uploadedfile'] ['name']）。 
已上载< br>; 
} else {
 echo< br>上传文件时出现错误，请重试。< br>; 
} 
}

< form method =post> 
将PDF添加到针对委员会和特殊项目的项目中< br>选择项目< select name =addsubp><？php 
 
 $ query =SELECT 
 projects 。*

个项目; 
 $ showresult = mysql_query（$ query）; 
 $ csp_c = 1; （$ buyarray = mysql_fetch_assoc（$ showresult））
 {
 echo< option value =。$ buyarray ['id']。>。$ buyarray [ PNAME ]。 < /选项>中; 
} 
 
？>< / select>< br> 
选择PDF的显示名称< input type =textname =addsubp_name/> <溴> 
选择PDF：< input name =uploadedfiletype =file/> <峰; br> 
< input type =submitvalue =将PDF添加到Comm和特殊项目name =submit/> 
< / form> 
  

我确定应用程序对comm目录具有写权限。我有godaddy，并使用文件管理器来确保。之前我在这个项目中遇到过权限问题，所以我知道这不是事实。它保持打印

上传文件时出现错误，请重试。

不会尝试上传任何PDF，我做错了什么？
thanks！

解决方案

您可能有权限问题，但对于文件上传，您的表单标记应包含适当的enctype属性。
$ b

< form enctype =multipart / form-datamethod =POST>

并定义文件大小限制也是一个好主意：

<输入类型=hiddenname =MAX_FILE_SIZEvalue =1000000/>

For some reason my PDF upload form is failing consistently, I have this code:

<?php
if($_POST["submit"] == "Add PDF to Comm and Special Projects")
{
    $addsubp = $_POST["addsubp"];
    $addsubp_name = $_POST["addsubp_name"];
    $commuploadedfile = $_FILES['uploadedfile']['name'];
    $sqldoc = "INSERT INTO projects_links (pid, display_name, link) VALUES ('".$addsubp."','".$addsubp_name."','".$commuploadedfile."')";
    mysql_query($sqldoc) or die(mysql_error());
    echo "<BR>";
    $target_path = "D:\\Hosting\\69903\\html\\pdfs\\comm\\";
    $target_path = $target_path . basename( $_FILES['uploadedfile']['name']);

    if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
        echo "<br>The file ".  basename( $_FILES['uploadedfile']['name']).
        " has been uploaded<br>";
    } else{
        echo "<br>There was an error uploading the file, please try again.<br>";
    }
}
?>
<form method="post">
Add PDF to Project for Committees and Special Projects <br>Choose Project<select name="addsubp"><?php

$query = "SELECT
projects.*
FROM
projects";
$showresult = mysql_query($query);
$csp_c = 1;
while($buyarray = mysql_fetch_assoc($showresult))
{
    echo "<option value=".$buyarray['id'].">".$buyarray["pname"]."</option>";
}

?></select><br>
Choose Display Name for PDF <input type="text" name="addsubp_name" /> <Br>
Choose PDF: <input name="uploadedfile" type="file" /> <Br>
<input type="submit" value="Add PDF to Comm and Special Projects" name="submit" />
</form>

I have made sure that the application has write privileges to the "comm" directory. I have godaddy and used the file manager to make sure of that. I have had problems with permissions in this project before, so I know this isn't case. It keeps printing

There was an error uploading the file, please try again.

It doesn't attempt to upload any PDF at all, what am I doing wrong? thanks!

解决方案

You may have permissions issues, but for file uploads your form tag should contain the proper enctype attribute.

<form enctype="multipart/form-data" method="POST">

and defining a file size limit is also a good idea:

<input type="hidden" name="MAX_FILE_SIZE" value="1000000" />
