Wordpress slideshow shortcode - php modification

[Bogh]

Hi, this is my first post on this forum and I hope I have posted it in the right place 

 

I am trying to modify a custom Wordpress Shortcode that produces slides. The shortcode works pretty well, but it's a bit complicated.

So, now in the shortcode I have to use:

 slide_1="Title #1" slide_2="Title #2" slide_3="Title #3"

and so on, like in the following shortcode:

[raw]
[slides style="framed" class=""  height="300"  slide_1="Title #1" slide_2="Title #2" slide_3="Title #3"]
[slide_1]Slide 1 content...[/slide_1]
[slide_2]Slide 2 content...[/slide_2]
[slide_3]Slide 3 content...[/slide_3]
[/slides]
[/raw]

 

How should I modify the PHP code of the shortcode so I don't need to use

slide_1="Title #1" slide_2="Title #2" slide_3="Title #3"

 

The PHP code is here: http://ideone.com/lZRGS.

Please let me know if I should provide more clarification.

 

Thank you.
