URGENT - Photo Album Viewer Script Not Working

**vlane95678** · 08-30-2006, 03:05 PM

1) Script Title: PHP Photo Album Script

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex4/indexb.html

3) Describe problem:

Hi world!

I am using the PHP Photo Album Script found on this site - DynamicDrive. This script allows the php to grab files in a particular folder and display them on the screen. Now here's the problem . . . it says that it will display the images by FILE NAME and also has the feature to display by DATE. I followed the instructions to display by FILE NAME, but it is not working. It keeps displaying the images by the date not the file name. I NEED IT BY FILE NAME!!

Can anyone debug this thing? Here's the script:

HTML:
<HEAD>
<style type="text/css">

.slideshow{ /*CSS for DIV containing each image*/
float: left;
margin-right: 11px;
margin-bottom: 10px;
}

.slideshow img{ /*CSS for each image tag*/
border: 0;
width: 135x;
height: 88px;
}

#navlinks{ /*CSS for DIV containing the navigational links*/
width: 400px;
}

#navlinks a{ /*CSS for each navigational link*/
margin-right: 0px;
margin-bottom: 05px;
font-size: 100%;
}

#navlinks a.current{ /*CSS for currently selected navigational link*/
background-color: #C6E959;
}
</style>
</HEAD>

You can see it in action here. IMPORTANT - go to Page 3 and mouseover/right click properties of the last few images. You'll see that the label doesn't match the file name:

HELP PLEASE!!! SOMEONE!! I've already posted this problem on another forum with no responses that worked.

Please don't cross post the same question in multiple categories (one in "JavaScript" has been deleted).

It seems to be working correctly for me. Note that the script sorts alphabetically, which means something like 11 would proceed 2.

**vlane95678** · 08-30-2006, 10:15 PM

Here is an example page of the script not working. The files names are letters only (i.e,. 'a', 'c') and the image itself display the letter of the file name.

It is clearly out of aphabetical order:

http://www.clientcardz.com/new/new.html

"Z" should not be the first image if it is sorting alphbetically.

Please help!

I looked through other people's post on this script and all the problems they were having with it as well.

I've decided to ditch fixing this problem and coming up with another solution. I am now using the file name in place of the visible text description below th e image. That's the only way around this problem.

Thank you to those who responded.

Ok, the problem then must be the way your server lists files within a directory. The PHP Photo album assumes that it's by file name, and doesn't attempt to do any type of sorting in that case. If your server somehow lists files in a different manner, the returned images will not be in alphabetical order.

Try modifying the code:

Code:

if (gsortorder=="asc" || gsortorder=="desc")
galleryarray.sort(sortbydate)

inside the JavaScript code (code of Step 3) to:

Code:

if (gsortorder=="asc" || gsortorder=="desc")
galleryarray.sort(sortbydate)
else
galleryarray.sort()
