Question

我想知道如何在PHP中上传文件，列出和下载文件？

我希望用户上传/列出/下载文件，例如：文件“Assignment Guide.doc”。

以下是我上传，列出，下载的代码。以下代码成功让用户上传，列出和下载文件。但是，资源管理器中的数据库，列表页面和目录中显示的文件名是“AssignmentGuideline.doc”而不是“Assignment Guide.doc”。我想知道是否有任何代码使得数据库，列表页面和资源管理器中的目录显示的文件名是“Assignment Guideline.doc”......

上传文件-process.php

<?php
    require("connection.php");
    session_start();
    $username = $_SESSION['UserName'];

    //This is the directory where files will be saved
    $filename = basename($_FILES['file']['name']);
    $filesize = intval($_FILES['file']['size']);
    $filenospace = str_replace(' ','',$filename); 
    $udir= "users/".$username."/";
    $ufile = $udir .$filenospace;

    //This gets all the other information from the form 
    $file = ($_FILES['file']['name']);
    $filenospace1 = str_replace(' ','',$file); 

    //Writes the information to the database 
    mysql_query("INSERT INTO files(UserName,FileName,Path,Size,Date) VALUES('$username', '$filenospace1', '$udir','$filesize',NOW())") ; 

    //Writes the file to the server 
    if(move_uploaded_file($_FILES['file']['tmp_name'], $ufile)){
        //Tells you if its all ok
        header('location:upload.php?feedback3=uploadsuccessful');
    }
    else {
        //Gives and error if its not
        header('location:upload.php?feedback3=uploaderror');
    }
?>

userpage.php - 其中显示上传的文件及其下载链接

<div class="box6">
    <h3>File Lists</h3>

        while($row=mysql_fetch_array($sqlUpload)){

Answer 1

似乎您正在插入$ filenospace1，但是关于此行，您无需空格替换空格：

$filenospace1 = str_replace(' ','',$file);

不要这样做“str_replace”或只是在SQL语句中插入$ file而不是$ filenospace1：

INSERT INTO files(UserName,FileName,Path,Size,Date) VALUES('$username', '$file', '$udir','$filesize',NOW())

最后，要显示数据：

//Replace this line
$string_space = str_replace('','&nbsp;',$filename);
//by this one
$string_space = str_replace(' ','&nbsp;',$filename);
