Next/Previous buttons

Ramsobot

I have a sequence of images which display one at a time on a page using php with the echo function/ID. I want to have "next" and "previous" buttons alongside these images which, for example if the current ?ID=4, one would point to ID=3 and the other ID=5.

The best example of what I want can be found here: TheNorm.com Comic Strips

Thanks for any help you can give!

Are you asking for the script to be written for you?

basicly the easiest way is to store image-links and imag-ID numbers in a Database. So when you add an image to your website it adds an entry into your database with the Image location and the auto-increments the ID field. now when you call for an image you can do a sort on the ID field and have the newest added image be on top and everyone after that in order from newest to oldest. Then have your script take the Image ID and make links with ID-1 and ID+1 for the Next and Previous buttons.

I'm sorry, that does sound like I want someone to do it for me. I'm just look for guidance.

That +1, -1 looks like what I was looking for. Does this seem right?

<img 
src='/strips/" . $ID+1 . ".jpg' />";

Thanks for your help.

well there are a few ways of doing it. You can either use a Database to store image location or just name the images in order, so image1.jpq, image2.jpg and so forth.

<img  

src="/strips/<?php echo $ID+1;?>.jpg" />

the example above is for entering PHP into a HTML page. probebly a little easier then doing HTML into a PHP page.

PS. if you do not want to code all of this yourself, check out http://phpcomic.com they use to cost money but now are Freeware.
