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.

Thanks Jerry!!

All I had to do was remove the line you suggested and it works perfect! :)

'where' => whereRecordNumberInUrl(1),

In addition to that... how would I go about having the "content" (top of page description) to display only on the 1st page - not on every single gallery page (accessed via the prev/next feature)

This page is a combination of two section editors "bird_photography_gallery" is a single record that contains just the title & content (gallery description).

The "bird_photos" editor is the multi-record photo gallery.

this is the script that pulls in the "content" (gallery description) and I want it to appear ONLY on the 1st page of the gallery.

<?php echo $bird_photography_galleryRecord['content'] ?>

Thanks!!! Tina

Hi Tina,

You might play around with wrapping your content in an if statement something like:
<?php echo $bird_photosMetaData['page'] == 1 ?>
<?php echo $bird_photography_galleryRecord['content'] ?>
<?php endif ?>

(if that doesn't work try 0 instead of 1. I'm not sure if the page count starts at 1 or 0)

Jerry Kornbluth

Thanks for the reply Jerry!

I tried the code: (tried 0, 1 & even 2)

<?php echo $bird_photosMetaData['page'] == 1 ?>
<?php echo $bird_photography_galleryRecord['content'] ?>
<?php endif ?>

I get this error:
Parse error: syntax error, unexpected T_ENDIF in /home/billd3/public_html/cmsAdmin/bird-photography.php on line 51

<?php endif ?> is line 51

Of course you got an error, and it's my fault. I copies the wrong line of code and didn't look closely enough at it.

the first line of code should be an if statement.

something like:

<?php if ($bird_photosMetaData['prevPage'] == 1): ?>

Sorry,

Jerry Kornbluth

I knew it had to be along the lines of an if this... then this statement but my brain is just scattered right now. It brought up just the second page with the content so I changed it to 0 like you suggest and it's perfect. Thanks a ton!! :)

Glad it worked

Really Nice Looking Site...

Thanks!! Just a few more touches including a slideshow on the homepage so I might be back on the forum for a little help with that but I'm going to try to tackle it on my own. :)

Thanks again - your help is really appreciated :)
