Previous/Next Image Buttons On Detail Page

Previous/Next Image Buttons On Detail Page

I'm wondering if the following is possible with the DataAssist pages I've created:

I have a gallery of images (Results page) in a grid format being fed by the database. On the Detail pages I'd like to have “Previous Image” and “Next Image” buttons so the user can navigate to other gallery images while on the Detail page instead of forcing them to go back to the Results page to choose another image.

Even just a push in the right direction would be helpful - I might be able to figure it out from there. Thanks.

the detail page uses a querystring variable to determine which record to show, for example:

details?ID=10


you can use simple math to create a link to the next or previous images using the querystring variable:

php:
<?php if(isset($_GET['ID'])) { ?><a href="details.php?ID=<?php echo($_GET['ID'] - 1);?>">Previous</a> <a href="details.php?ID=<?php echo($_GET['ID'] + 1);?>">Next</a><?php ?>




couple of issue to be aware of though:
1) If the ID is the previous link will point to 0 which will load a no record found page.
2) If you delete images, there may be a break in id values, so you may get an occasional no record found page in the middle.
3) once you get to the last image, the next link will point to an id that does not exist.

Jason, thanks so much for the solution and for the possible obstacles. Can show if statements be used on the Previous/Next links similar to the First | Next | Previous | Last links on the Results page? Or maybe I emulate those same types of links on the Detail page altogether?

Also, concerning the database values in case a record is deleted... I'm assuming you can't reorder the values in MySQL to remove any gaps? Thanks again.

No, the show regions cannot be used, they rely on record set data.

the ID is set by the database, when a record is deleted, that id is deleted, the ID s cannot be regenerated.
