Easiest way to get list of files in the server directory

javascript php image server

Solution 1

Javascript cannot fetch all files on a server, as it is a client-side langugage.

http://php.net/manual/en/function.glob.php is what you need.

$all = glob('/path/to/dir/*.*');

$images = glob('/path/to/dir/*.{jpg,png,gif}');

I disagree with @mariobgr. If there is no server setting preventing a directory listing, then the html generated by requesting that directory can be parsed for the contents.

$ tree maindir
maindir
├── index.html
└── somedir
    ├── doc1
    ├── doc2
    └── doc3

index.html

<!DOCTYPE html>
<html>
<head>
  <meta charset="UTF-8">
  <meta content="IE=edge,chrome=1" http-equiv="X-UA-Compatible"><!--  JQUERY  -->

  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js">
  </script>
  <title></title>
</head>
<body>
  <h1>Listing /somedir</h1><!-- Custom Script (defered load, after dom ready) -->
  <script>
    $.getJSON('./somedir', data => {
        console.log(data); //["doc1.jpg", "doc2.jpg", "doc3.jpg"] 
    });
  </script>
</body>

I managed to do it in base javascript using a modifyed ajax command to get the folder list as an html file. Then I grep the file names from inside of it:

function loadDoc() {
            var xhttp = new XMLHttpRequest();
            xhttp.onreadystatechange = function() {
                if (this.readyState == 4 && this.status == 200) {
                    
                    // gets the entire html file of the folder 'logpost' in this case and labels it thing
                    thing = this.responseText
                    searchFor = /.html</g
                    a=0;
                    b=0;
                    var str = "";
            
                    // greps file for .html and then backs up leter by letter till you hot the file name and all
                    while ((dothtmls = searchFor.exec(thing)) != null ){

                        str = "";
                        console.log(dothtmls.index);
                        
                        a = dothtmls.index;

                        while (thing[a]  != '>' ){
                            a--;
                        }
                        a++;
                        while(thing[a] != '<'){
                            str = str + thing[a];
                            a++;
                        }
                        console.log(str);
                    } 
                }
            };
            xhttp.open("GET", "logpost/", true);
            xhttp.send();
            }

This is probably not the cleanist way but if you are working on a static web sever it should work :)

I need to get array of all images (or simply of all files) in directory (e.g. www.example.com/images/). I prefer to use JavaScript but it's hard to make. So should I use PHP, meybe?

Could you please help me - I'm not good at this.

Thank you very much!

Well, yes, but node.js seems to be an overkill is this case. Did you try my suggestion?
Jan Chalupa almost 9 years

Thank you very much. I tried this but now I detect error which cause it doesn't work. When I use echo in give text "Array", I guess it's fine. Now I just need to loop throught this array to get file names - am I right?

This doesn't work. $images = glob('http://www.honzachalupa.cz/dev/imgs/*.{jpg,png}'); foreach($images as $image) { print $image; }

Don't use the domain, but the path to the images directory. For example /home/example.com/public_html/images

Even if I use relative path and change print to echo it won't work. <?php $images = glob('/imgs/*.{jpg,png}'); foreach($images as $image) { echo $value; } ?>

I doubt that's the path to your images. Put echo getcwd(); in your script to see the actual directory you are in.

echo getcwd(); gives me D:\v000000\honzachalupa.cz\WWWRoot\dev Directory of my images is e.g. www.honzachalupa.cz/dev/imgs/bg-1.jpg, bg-2.jpg etc.

so you should execute glob(D:\v018912\honzachalupa.cz\WWWRoot\dev\imgs\*.{jpg,png}‌'');

It won't help. I'm probably cursed... :)

I removed the extension ´{jpg,png}´ and in works. :)

Can this search for files recursively through multiple folders?

I created a website project with VS and try your solution but unfortunately, nothing appears. do I need to setup anything?

@Amir Make sure you have directory listing enabled on the directory.
