wrong order of images with readdir()

1 New Member

Hi guys....
i know this question has been asked already and I found a few answers but it would be soo great if anyone could help me with this script, which just browses images on a webpage in an image folder on a server.

the script so far is working (a friend gave it to me):

http://dev.perfectday.gb.com/tom/chiaraweb/photo.php

the number on the images are the filenames. I want to order the images by filenames.

the only thing is the order of the images.
I know there is a way with scandir but as I am a beginner with php I am not able to fit the right piece of code into the right bit of my photos.php.

if anyone could tell me how I can make this work would be amazing.
I am making this website for a freind so that I cannot hire any programmer for that :(

this is the code of the photo.php.

I didnt ue the part with the category.

thanks a lot

Heya, kirstenkirsche.

Use scandir() to store the filenames in an array (http://php.net/scandir), then use sort() to sort the array (http://php.net/sort).

Displaying Images form a Directory

Happy New Year, Everyone! I am trying to figure out how to display a bunch of images (mainly JPEGs, but possibly a few GIFs and PNGs as well) that are stored in a local directory on the system. I can do this with the glob() function, but I can't seem to put in a directory other than one within the webroot. For example, I can only put "/uploads" and not "/Volumes/jray/Pictures...".
