Question

我正在尝试实施一个提交系统，人们可以在其中填写个人信息并附上文件上传。他们的信息应该记录到MySQL数据库中，文件应该重命名为其中一个字段，然后是扩展名。这是我到目前为止所拥有的......

这是表单页面：

<html>
<head>
<title>Submissions Script DEV</title>
<style type="text/css">
/**** Start page styles ****/

body {
    background: #DFA01B;
    font-family: arial, sans-serif;
    font-size: 14px;
    }

#wrap {
    max-width: 600px;
    margin: 30px auto;
    background: #fff;
    border: 4px solid #FFD16F;
    -moz-border-radius: 15px;
    -webkit-border-radius: 15px;
    border-radius: 15px;
    padding: 20px;
    }
</style>
<body> 
<div id="wrap">
    <div align="center">
    <a href="http://siteurl.com"><img src="logo.png" /> </a>
    <h1 style="font-family:arial">Submissions</h1>
    <p style="font-family:helvetica"> <i> Welcome to the submission page</i> </p> 
</div>
<form method="POST" action="upload.php" enctype="multipart/form-data">
    <p>
              Please enter your first name: <input type="text" name = "fname">
            <p>
              Please enter your last name: <input type="text" name= "lname">
            <p>
              Student #: <input type="text" name= "snumber"/>
            <p>
            Grade: <select name= "grade">
            <option>9</option>
            <option>10</option>
            <option>11</option>
            <option>12</option>
        </select>
        <p>
<hr>
            <!---Upload file section begins--->
              Please attach your Powerpoint (ppt/pptx/zip) file. The file should be     named student#.zip. (For example; 123456.ppt)
        </p>
        <input type="hidden" name="size" value="1024000">
            <input type="file" name="upload"> 

        <p>
        <br/>
        <br/>
        <div align="center">
        <input type=button onClick="location.href='instructions.html'" value='Back'>
        <input TYPE="submit" name="upload" title="Send your submission" value="Submit Portfolio"/>
        </div>
      </form>
<p>   
<!---Footer Styling--->
<div style="font-family: Arial;
font-size: 10px;
color: grey;
align: center;">
<!---Footer Contents--->
    <p>Copyright <a href="http://sitename.com">site</a>site</p>
</div>  
</div>
</body>
</html>

这是upload.php：

<?php

//This is the directory where images will be saved
$target = "uploads/";
$target = $target . basename( $_FILES['upload']['name']);

//This gets all the other information from the form
$fname=$_POST['fname'];
$lname=$_POST['lname'];
$upload=($_FILES['upload']['name']);
$snumber=$_POST['snumber'];
$grade=$_POST['grade'];

// Connects to your Database
mysql_connect("localhost", "db_user", "dbuserpass") or die(mysql_error()) ;
mysql_select_db("sub-data") or die(mysql_error()) ;

//Writes the information to the database
mysql_query("INSERT INTO `Submissions` VALUES ('$fname', '$lname', '$snumber', '$grade',         '$upload')") ;

//Writes the upload to the server
if(move_uploaded_file($_FILES['upload']['tmp_name'], $target))
{

//Tells you if its all ok
echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded, and your information has been recorded";
}
else {

//Gives and error if its not
echo "Sorry, there was a problem uploading your file.";
}
?>

最后，我希望使用表单中的snumber字段来命名文件上传。例如，如果某人在snumber字段中填写12345并上传.zip文件，则应自动将其重命名为12345.zip并存储在相应的目录中。

我该怎么做呢？我是PHP的新手，但我已经做了一些关于这个问题的研究，虽然我没有找到任何适合这个需求的东西。

只需使用目标文件名的值更新$target变量即可。例如，更改

$target = "uploads/";
$target = $target . basename( $_FILES['upload']['name']);
if(move_uploaded_file($_FILES['upload']['tmp_name'], $target))

到

$extension = explode(".", $_FILES['upload']['name']);
$extension = $extension[count($extension)-1];
$target = "uploads/";
$target = $target . $_POST['snumber'] . "." . $extension;
if(move_uploaded_file($_FILES['upload']['tmp_name'], $target))

将PHP上载重命名为字段条目
