php - 使用 php 更改链接单击时回显内的目录名称或路径

问题描述

我正在尝试创建艺术家画廊。画廊已创建，但当我需要 50 位艺术家时，我必须创建 50 个页面。因此，单击链接后，我只需要更改文件夹的方向。最好的方法是什么？链接到我的画廊 http://www.divart.sk/vg/krajina.php

艺术家的链接

<option value="http://www.divart.sk/vg/krajina.php">krajina</option>
<option value="http://www.divart.sk/vg/virtualgallery.php">Adina Chitu</option>

php代码

$dir = "krajina/";
if (is_dir($dir)){
  if ($dh = opendir($dir)){
    while (($file = readdir($dh)) !== false){
      if( $file == '.' || $file == '..')
        continue;
      echo " <div><img src='krajina/" . $file . "'/></div>";
    }
    closedir($dh);
  }
}

解决方案

您可以通过using ( Parse String ) 和ScanDir将文件夹名称传递给php 脚本来做简单的事情。Query String

您必须创建此结构：

http://www.divart.sk/vg/gallery.php?dir=the_artist_folder

http://www.divart.sk/vg/krajina/

http://www.divart.sk/vg/nicole/

http://www.divart.sk/vg/jonathan/

其中文件夹名称是文件夹艺术家，而gallery.php是读取文件夹艺术家的php 脚本！

根据评论中的要求，您可以通过加载放置在文件夹艺术家中的文本文件（不是最佳方式）来添加艺术家信息，例如：

http://www.divart.sk/vg/krajina/artist.txt

http://www.divart.sk/vg/nicole/artist.txt

http://www.divart.sk/vg/jonathan/artist.txt

文本文件示例artist.txt：

Artist: krajina;
Born: 1967/04/18;
Photo Genre: Nature;
License Photo: Creative Commons;

例如：<option value="http://www.divart.sk/vg/gallery.php?dir=krajina">krajina</option>

gallery.php

如果你看到 PHP 生成的html 源代码，你可以看到：

<!DOCTYPE html>

<html lang="en">

  <meta charset="UTF-8">

  <link rel="stylesheet" type="text/css" media="all" href="gallery.css">

我希望这有帮助。
