Background

I am building a website. The files are:

/index.php
/pic.jpg
/dir/index.php
/dir/pic.jpg

As we know, people can visit my site's dir/index.php page using different URLs: 

1. site.com/dir
2. site.com/dir/ 
3. site.com/dir/index.php

I have a link in /dir/index.php

<a target="_blank" href="pic.jpg">

which I want to relativly link to /dir/pic.jpg

The Problem

---------------------/-------------------------------                    
                             index.php
           pic.jpg
              ^
              |
        ------|-----/dir/------------------------
        |     |                                 |
        |     | 1                               |
        |     |                                 |
        |     |       2 or 3                    |
        | index.php ---------> pic.jpg          |
        -----------------------------------------
-----------------------------------------------------

The href="pic.jpg" leads people to different places when people visit the web via different urls.

People using url 1 get /pic.jpg , and others using url 2 or 3 get /dir/pic.jpg

The same problem goes with not just <a> but other HTML tags.

How can I write a relative URL in /dir/index.php that links to /dir/pic.jpg whatever URL visitors use?

I need to keep folder dir portable (I may change dir's name, or use dir folder on another website, so it may have different path). We need a solution other than hardcoding href="/dir/pic.jpg".

  • Why do not you just choose a different name for the `pic.jpg`? – Spirit May 25 '19 at 15:50
  • site.com/dir should automatically redirect to site.com/dir/ when /dir is actually a directory and presto, your "problem" is solved – HBruijn May 25 '19 at 16:34

The problem is that you have somehow not added a trailing slash to the first URL. If this directory actually exists on your server, then you would have had to intentionally misconfigure the web server to do this. You should undo that configuration, so that the server redirects the first example to the second example (the default).
