如何将正确的文件目录位置指定为属性

星期六大家好!

所以我有这个PHP代码,显示特定文件夹中的所有文件。一切运行良好,按预期工作。

我只有一个问题,当显示文件时,让我说我想查看我的webbrowser上的特定文件,我点击该文件,我得到了“找不到对象”#39;页。当我查看网址时,我知道为什么找不到该网址,因为网址显示为:http://localhost/studybuddy/maths.txt

但是文件maths.txt位于文件夹' uploads'所以网址必须说: http://localhost/studybuddy/uploads/maths.txt以显示该文件。

这是我的代码:

<!doctype html>
<html>

<head>
  <meta charset="UTF-8">
  <title>Student Notes</title>
  <link rel="stylesheet" href="style.css">
  <script src=".sorttable.js"></script>

  <style>
  .upload{
    position: absolute;
    top: 400px;
    right: 800px;
    }  
  </style>


</head>

<body>

  <div id="container">

    <h1>Student Notes</h1>

    <table class="sortable">
      <thead>
        <tr>
          <th>Filename</th>
          <th>Type</th>
          <th>Size <small>(bytes)</small></th>
          <th>Date Modified</th>
        </tr>
      </thead>
      <tbody>
      <?php
        // Opens directory
        $myDirectory=opendir("./uploads/");

        // Gets each entry
        while($entryName=readdir($myDirectory)) {
          $dirArray[]=$entryName;
        }

        // Finds extensions of files
        function findexts ($filename) {
          $filename=strtolower($filename);
          //$exts=split("[/\\.]", $filename);
          $n=count($exts)-1;
          $exts=$exts[$n];
          return $exts;
        }

        // Closes directory
        closedir($myDirectory);

        // Counts elements in array
        $indexCount=count($dirArray);

        // Sorts files
        sort($dirArray);

        // Loops through the array of files
        for($index=0; $index < $indexCount; $index++) {

          // Allows ./?hidden to show hidden files
          if($_SERVER['QUERY_STRING']=="hidden")
          {$hide="";
          $ahref="./";
          $atext="Hide";}
          else
          {$hide=".";
          $ahref="./?hidden";
          $atext="Show";}
          if(substr("$dirArray[$index]", 0, 1) != $hide) {

          // Gets File Names
          $name=$dirArray[$index];
          $namehref=$dirArray[$index];

          // Gets Extensions 
          $extn=findexts($dirArray[$index]); 

          // Gets file size 
         $size=number_format(filesize("./uploads/".$dirArray[$index]))."&nbsp;";

我的问题是,如何将正确的目录作为属性分配给文件?

我希望我已经给你足够的信息。

您可以替换

$namehref = $dirArray[$index];

通过

$namehref = "uploads/" . $dirArray[$index];
