[RESOLVED] Slideshow Help

[bripriuk]

Hi

I use a simple slideshow script called Micro Photo Slideshow I found for my website. It works very well but there is one problem, it shows the photos in a random order ( I have named the files sequentially).
http://www.secalis.co.uk/ssi/ssi.php
Could some kind member point me in the right direction so that the photos are shown in order?
I can write simple PHP ,but not database scripts. Here is the script I use

/************* S E T T H I S V A R I A B L E S ****************************/
$timer = 4; // Switch to the next image after 5 sec
$title = "Micro Photo Slideshow"; // Title of your photo album
/******************************************************************************/


function displayPhoto(){
global $gid;
$id = isset($_GET['id']) ? $_GET['id'] : 0;
$actFile = 0;

// Open the actual directory
if ($handle = opendir(".")) {
// Read all file from the actual directory
while ($file = readdir($handle)) {
// Check whether tha actual item is a valid file
if (is_file($file)){
// Check whether the actual image is a thumbnail
if ((strpos($file,'.jpg')) || (strpos($file,'.jpeg'))){
if ($actFile == $id){
return '<img src="'.$file.'" class = "image" alt="Slideshow" />';
}
if ($actFile == 0){
$first = '<img src="'.$file.'" class = "image" alt="Slideshow" />';
}
$actFile++;
}
}
}
}
$gid = 1;
return $first;
}

$gid = isset($_GET['id']) ? $_GET['id'] : 0;
$gid++;

$image = displayPhoto();

$url = $_SERVER['PHP_SELF'].'?id='.$gid;

?>

TIA

You want to use sort() to sort the files after you open up the directory.
I would read up on tutorials on how to display, and write to, files and directories.

I use both display and write to files and dirs, to include function modules for my software based on the the licence key.

And remember echo and print_r are you friends to see what is going on in the background while you are programming.

In getting something that sort can be used on, scandir would be more convenient than the opendir/readdir/closedir loop.

Even better: glob() is a little more concise, especially given that you could do something like:

glob('*.{jpg,jpeg}', GLOB_BRACE) 

to take care of the filename filtering for you.

Thanks for the replies, they are exactly what I need.
By the way, how do you add the PHP code box to the message?

Does this mean you've resolved the problem? If so, don't forget to mark this thread resolved using the link on the Thread Tools menu above.

By the way, how do you add the PHP code box to the message?

You can either manually type out the [php]..[/php] bbcode tags, or you can use the PHP code icon on the advance editor page (last icon in the second row).

Many thanks for the help, I used the glob option suggested by Brad.
