Photo Gallery- next/prev links not displaying images

Hi Tina,

Here’s a recipe from my CMSB Cookbook http://www.thecmsbcookbook.com that might offer some insights. It deals with previous/next page links.

PREVIOUS/NEXT PAGE LINKS ONLY IF DESIRED IMAGES PER PAGE COUNT IS EXCEEDED


IF UPLOAD FIELDS ARE IN SEPARATE RECORDS

I wanted to display previous and next links on a page but only if there were more than a user specified number of image records available.

First I created a text field called thumbnails_per_page in the single record editor that I call common_information, where the client could enter the maximum amount of images to allow per page.

Then, at the top of the viewer page I defined a variable called $maximages, and added a ‘perPage’ to the “list records” call using that variable, like this:

$maximages = ($common_informationRecord['thumbnails_per_page']);
list($portfolio_imagesRecords, $portfolio_imagesMetaData) = getRecords(array(
'Table name' => 'portfolio_images',
'perPage' => $maximages,

));

NOTE: the variable definition has to be outside the list records call and there are no single or double quotes around $maximages in 'perPage' => $maximages, or the variable won’t work.

I also found it necessary to remove the:

'where' => whereRecordNumberInUrl(1),
from the “list records” call that listed the common_information records.

To generate the Prevous/Next links I used this code in the body of the page:

<?php if ($portfolio_imagesMetaData['totalPages'] > 1): ?>

This is Page <?php echo $portfolio_imagesMetaData['page'] ?> of <?php echo $portfolio_imagesMetaData['totalPages'] ?>

<?php if ($portfolio_imagesMetaData['nextPage']): ?>
<br /><a href="<?php echo $portfolio_imagesMetaData['nextPageLink'] ?>">Click Here to See More of My Work.

</a>

<?php endif ?>
<?php if ($portfolio_imagesMetaData['prevPage']): ?>
<br /><a href="<?php echo $portfolio_imagesMetaData['prevPageLink'] ?>">Click Here to See My Previous Portfolio Page.</a>

<?php endif ?>
<?php endif ?>
There’s also some additional information on other implementations in this post: http://www.interactivetools.com/forum/gforum.cgi?post=75239

Hope it solves some issues.
