When I set out to add database driven player info at NuggetsHoops.com, I knew that I wanted to include code that would display some of the many images that I had set aside for each NBA player. I also knew that I would continue to add new pictures. Application code that could easily display old and new images, without additional effort for each added image would work best.

I had already written PHP code that could look at a folder and create a list of images to be displayed. When I ran across the powerful jQuery Cycle Plugin, I had found a great way to display them.

Let’s get coding. This tutorial depends on PHP 5, jQuery 1.2.3 or later, jQuery Cycle Plugin version 2.51 or later.

Add the following Javascript to your PHP/HTML to enable and call the Cycle Plugin:

 javascript |  copy code |? 
1
<script src="/scripts/jquery-1.3.2.min.js" type="text/javascript"></script>
2
<script src="/scripts/jquery.cycle.all.min.js" type="text/javascript"></script>
3
<script type="text/javascript">
4
$(document).ready(function(){
5
	$('#myslides').cycle({
6
		fit: 1
7
	});
8
});
9
</script>

Note that there are many options and styles of animation provided by the powerful Cycle plugin.

Add the following PHP to iterate over any folder and dynamically generate img tags using any images found in the folder:

 php |  copy code |? 
01
$directory = 'images/players/' . $row['imageName']; 
02
try {    
03
	// Styling for images
04
	echo "<div id=\"myslides\">";
05
	foreach ( new DirectoryIterator("../" . $directory) as $item ) {			
06
		if ($item->isFile()) {
07
			$path = "/" . $directory . "/" . $item;
08
			echo "<img src=\"" . $path . "\" />";
09
		}
10
	}
11
	echo "</div>";
12
}
13
catch(Exception $e) {
14
	echo 'No images found for this player.<br />';
15
}

Any img tags within an HTML element of class ‘myslides’ (or whatever you initialized the Cycle plugin with in the Javascript) will have the slideshow behavior added to it. The $row array on line 1 is referencing a database query result, but could be set in a number of ways for your specific needs. The DirectoryIterator reference on line 5 is a builtin class in PHP5.

Here’s the CSS to style the images being displayed in the slideshow:

 css |  copy code |? 
01
#myslides {
02
width: 340px;
03
float: right;
04
        padding: 0;
05
        margin:  0 auto;
06
margin-top: 20px;
07
} 
08
 
09
#myslides img {
10
    padding: 10px;
11
    border:  1px solid rgb(100,100,100);
12
    background-color: rgb(230,230,230);
13
    width: 320px;
14
    top:  0;
15
    left: 0
16
}

So, there’s a very quick walk thru a working example to generate a dynamic slideshow from any folder of images. If you’d like a full download of the code, or any further explanation, please leave a comment!

I like jquery so much

    thanks and regards

    jjmc,

    Make sure the path to your images folder is correct, based on lines 1 and 5 in the PHP source. I had to add “../” in the arg sent to the DirectoryIterator because my PHP file was in a subfolder, so the path to get to my images folder was ../images/players/anthony and so on. That path is relative to where your PHP file is on your server.

    Hope that helps! I’ll be happy to post the full source here, but won’t be able to get to that for another day or two.

    thanks developer for replying.. what I’ve got now is that it is now displaying the image..but my problem now is that , it is animating. it’s only shows the image.

    also is it possible to do some descriptions everytime it loads the image.. can we do like that.. here is the code that i have..

    can you help me on this please…or any suggestions

    Untitled Document

    $(document).ready(function(){
    $(‘#myslides’).cycle({
    fit: 1, pause: 1, height: 360

    #myslides {

    can u please help me to debug this code.

    my image is under images/player/pic1.jpg

    am having this on my browser as result
    No images found for this player.
    thanks you

  7. alan Says:

    San,

    It appears that your image and your directory code are not in sync. On line 7, from my example I was looking for player images in “images/players/…” while you’ve stated that placed your image in “images/player/…”.

    If that’s not your issue, can you provide a link to where you are trying this?

    my code

    $select=mysql_query(’select photosproduit from produit where isslide=’1”)

    please help me to implement this part in my code..
    thank you

  10. alan Says:

    Excellent – glad to hear that you got it working! I was about to post that I will be adding a zipfile of the code from this tutorial to make it easier for people to get started.

    As for pulling images from a database – are you storing the entire binary image in the database or just the path to the image on your server?

  11. san Says:

    Thank You
    the path of the images that is inserted in the database is uploads/picture1.jpg
    and the folder uploads is on my server.

    can you help me please..

    Hello,
    Your script is awesome. Coupling jQuery and PHP for a slideshow like this is perfect. The only problem that I encountered is that with this code Safari loads each image onto the page for a little while until all of the images are loaded and then switches to a single image and runs the slideshow as it should. Any ideas on how to solve this? Safari is a PITA but as a mac user I always try to accommodate it.

    Very nice and useful tutorials to web designers,
    Thanks for posting.

  14. alan Says:

    timska77 – Thanks! Strange – I don’t see that behavior in Safari 4 on Mac or PC. Are you seeing this issue with an older version of Safari?

    Here’s my test example, which uses a slightly modified version of the code from this tutorial:
