Rather than changing my code to display JPG's etc, everytime I add or delete one, I would like to be able to read the file names in a directory and determine which files should be displayed. Is there a way to do this? Any help will be greatly appreciated.

well with php you could:

1) get a list of all files in the folder
2) get all the ones that are jpegs, gifs, etc
3) display them on the page in a format you like

Like this:

PHP Code:

$path = "images/"; 

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

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

if($file == "." || $file == "..") 
continue; 
checkImage($file); 

} 

// Close 
closedir($dir_handle); 


That will list all files in the folder except "." and ".." then run a function on each file as it loops to determine whether it is an image or not:

PHP Code:

function checkImage($img_file) {
     if ( preg_match("/(\.gif|\.png|\.jpg)$/", $img_file) ) { 
          echo '<img src="images/'.$img_file.'" />';
      }
} 


I have't test this code, i jsut guessed but i can do a complete script for you on this, depends really on your host as im only really an knowledgable in PHP.

Thanks

I'm not familiar with PHP, only Script, but I may have to get familiar it. Does this work just like script?

What do you mean by "script"?

HTML isn't a scripting language, it's a markup language (referring to thread title).

PHP is a scripting language, so is JavaScript.

JavaScript is client-side, and PHP is server-side.

Sorry, I mean JavaScript. I haven't had time to use the example yet, but I'm guessing that it works just like JavaScript.

Thnx

Oh ok, then yeah it's kinda similar. They both use /* and */ for comments.

With PHP you have to wrap all code between <?php and ?> tags. And the page has to have a ".php" file extension.

How PHP differs from javascript: A variable in PHP starts with $ like $hello, whereas in JS a variable starts with "var" as in var hello.
