[SOLVED] Directory listing

[Timma]

Hi there,

I'm wondering how I should go about creating a sort of dynamic list.

I have a folder, let's just call it folder, which is filled with files called... file01.jpg file02.jpg and so on, there is also a folder in folder called folder1. These are all contained in localhost/site/.

 

What I am wanting to do on a php page is list all the "files" inside folder, but not show folder1 in that list, and also for the files to be listed correctly, not like 1, 10, 11, ..., 2, 21, etc.

Plus above some files there will be headings. (These are all links as well to a php page files.php?#)

 

And finally I would like to know how to, instead of displaying the filename, which would usually happen, but instead just cutting off the word "file" and the ".jpg" after the number.

[Timma]

Bump.

Here ya go Timma, hope this helps! (I tried to comment it enough lol)

 

 

function list_files($dir)
{
//checks the directory given to make sure its actually a directory.
  if(is_dir($dir))
  {
  //opens the directory for reading.
    if($handle = opendir($dir))
    {


	//reads each file in the directory.
      	while(($file = readdir($handle)) != false)
      	{
		//eliminates the files listed frombeing read.
        	if($file != "." && $file != ".." && $file != "Thumbs.db" /*pesky windows, images..*/)
        	{
			//this outputs the files name
			print"$file <br />";

        	}
     	}
      closedir($handle);
    }
  }
}

[Timma]

Thanks, but that only answers one question. 

 

Actually that doesn't work D:

 

But still, could people look at the other things too.

[piznac]

Actually that doesn't work D:

 

Actually it works quite well.

[Timma]

Fine then, when I attempt using it doesn't work. Rephrased, happy?

Still need help with these two, bump.

[Timma]

Bump, 'cause I can.

[MadTechie]

you may want to post the way your using the list_files function

 

as for the 2nd question

replace

print"$file <br />";

with

$filedisplay = preg_replace('/[a-z.]/si', '', $file);
print"$filedisplay <br />";

[Timma]

Hmm, thanks I guess.

 

Could you please explain the second method a bit more?

 

(My mind is completely blank on the first answer )

[MadTechie]

basically it replaces the letters and the dot with nothing thus leaving the number only

 

the first code should start like this

list_files("data/myimages/")

function list_files($dir)
{
//...snip

[Timma]

Okay, well as I'm using a server on my PC I just link to the C:/ folder which it is in, this works with my other script, which I found somewhere on the interwebs. I used list_files with ("C:/WEB_SERVER/www/site/folder/")

 

And I'm using this script now:

 

<?php

$path = "C:/WEB_SERVER/www/site/folder/";

    // Open the folder
    $dir_handle = opendir($path) or die("Unable to open $path");

    // Loop through the files
    while ($file = readdir($dir_handle)) {

    if($file == "." || $file == ".." || $file == "index.php" )

        continue;
        echo "<a href=\"$file\">$file</a><br />";

    }
    // Close
    closedir($dir_handle); 
?>

[MadTechie]

with that code you could just

change

echo "<a href=\"$file\">$file</a><br />";

to

$filedisplay = preg_replace('/[a-z.]/si', '', $file);
echo "<a href=\"$file\">$filedisplay</a><br />";

 

for the numbering..

 

as for the path ($path = "C:/WEB_SERVER/www/site/folder/"

shouldn't that be

$path = "site/folder/";

?

 

[Timma]

No idea, that directory works, so I use it. This script said I had to use it directly from the root of the website.

[MadTechie]

C:/WEB_SERVER/www/ is the windows path to the root of the site, thus if your script calls a file from the root (/) then it will look from their..

 

hope that makes sense!  :-\

[schme16]

to get the root dynamically you can use the function : getcwd()......

[Timma]

/**
* Change the path to your folder.
* This must be the full path from the root of your
* web space. If you're not sure what it is, ask your host.
*
* Name this file index.php and place in the directory.
*/
    // Define the full path to your folder from root
    $path = "/home/content/s/h/a/shaileshr21/html/download"; 

 

Well, I assumed home was like C:/ and html was like www so therefore that's what I did, I used the C:/......./www/.... thing.

[MadTechie]

Windows(system) Root = c:\

 

but if the webserver also used then when someone came to your site they could see all your files etc..

so the webserver asks where your webefile/site is stored (or it has a default), now that path is the web servers root..

 

so you on your computer see c:\ as the root but other people connecting throught your server see the webservers root.. so when it refers to root its infact refering to the webroot ("root of your web space").

 

[Timma]

So when uploaded to an actual web server, rather than my computer what modifications to the path would I have to do?

[MadTechie]

use Relative Paths

 

Relative Path URLs

 

Relative paths change depending upon what page the links are located on. There are several rules to creating a link using the relative path:

 

    * links in the same directory as the page have no path information listed

      filename

    * sub-directories are listed without any preceding slashes

      weekly/filename

    * links up one directory are listed as

      ../filename

 

How to determine the relative path:

 

  1. Determine the location of the page you are editing.

      This article is located in the/library/weekly folder on my site.

  2. Determine the location of the page or image you want to link to.

      The Beginner's Resource Center is located here: /library/beginning/

  3. Compare the locations and to decide how to point to it

      From this article, I would need to step up one directory (to/library) and then go back down to the beginning directory

  4. Write the link using the rules listed above:

      <a href="../beginning/bl_begin.htm"> ...</a>

 

as for the Dirlist, try this

 

// get the Absolute Path  (see link above)

$path = dirname(__FILE__)."/";

//goes up a folder to a folder called images

$path .= "images/";

 

[Timma]

Alright everything works, yet there are headings which need to be there, for example my site should look like...

 

Heading 1 -

01, 02, 03, 04, 05, 06, 07, 08, 09, 10, 11

 

Heading 2 -

12, 13, 14 ,15 ,16

 

Heading 3 -

17, 18, 19, 20, 21, 22, 23, 24

 

Yet obviously it looks like:

01, 02, 03, 04, 05, 06, 07, 08, 09, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24

[Timma]

Bump, 'cause I'm allowed.

[MadTechie]

can you please explain the logic behind the headers..

 

why would 1 go from 1 to 11 but header 2 only go from 12 to 16 ?

[Timma]

Well with that I was basically showing that it isn't a constant number each time.

Also the headings aren't actually Heading 1 and Heading 2 they are completely different words every time.

We'll need to use php's read_mind() function to help more.
