I am getting what I think is an odd value for both the previous and next page links:

$portfolioMetaData['prevPageLink']
gives me: ?portfolio=&index.php=&page=1

$portfolioMetaData['nextPageLink']
gives me: ?portfolio=&index.php=&page=3

This is causing issues with my ability to use the allow search feature. here is the relevant code I am using...

list($portfolioRecords, $portfolioMetaData) = getRecords(array(
'tableName' => 'portfolio',
'allowSearch' => '1',
'perPage' => '6',
));

<div class="pagination">
<?php if ($portfolioMetaData['prevPage']): ?>
<a href="<?php echo $portfolioMetaData['prevPageLink'] ?>">&lt;</a>
<?php else: ?>
<a class="inactive">&lt;</a>
<?php endif ?>

<?php
if (@!$_GET['page']): $current_page = "1";
else: $current_page = $_GET['page'];
endif;
?>

<?php foreach (range(1,$portfolioMetaData['totalPages']) as $page): ?>
<?php if ($page == $current_page): ?>
<a class="current"><?php echo $page; ?></a>
<?php else: ?>
<a href="?page=<?php echo $page; ?>"><?php echo $page; ?></a>
<?php endif ?>
<?php endforeach; ?>

<?php if ($portfolioMetaData['nextPage']): ?>
<a href="<?php echo $portfolioMetaData['nextPageLink'] ?>">&gt;</a>
<?php else: ?>
<a class="inactive">&gt;</a>
<?php endif ?>
</div>

Hi Zip,

If you could fill out a [url http://www.interactivetools.com/support/]2nd Level Support Request[/url] I can take a closer look into this.

In the comments of the request, be sure to indicate which .php file is experiencing the problem.

Thanks

Hello, All -

Did you ever resolve this issue? If so I wonder if it would help me with my issue? I'm also getting some weird results in my pagination links.

This is the showme output:

Array
(
[invalidPageNum] =>
[noRecordsFound] =>
[page] => 2
[perPage] => 12
[fromCache] => 0
[totalPages] => 2
[totalRecords] => 15
[pageResultsStart] => 13
[pageResultsEnd] => 15
[prevPage] => 1
[nextPage] =>
[prevPageLink] => /index.php?cat=6&amp;amp;gal=13&amp;page=1
[nextPageLink] => /index.php?cat=6&amp;amp;gal=13&amp;page=
[firstPageLink] => /index.php?cat=6&amp;amp;gal=13&amp;page=1
[lastPageLink] => /index.php?cat=6&amp;amp;gal=13&amp;page=2
[_detailPage] =>
[_listPage] => javascript:alert('Set List Page Url for this section in: Admin &gt; Section Editors &gt; Record &gt; Viewer Urls')
)

The generated links are full of ampersands - which is having a serious knock on effect for some of my other page code.

What's causing this?

Hi Perch,

The links are generated to have all the same data currently in the URL plus a "page" variable at the end. When outputted, all the &amp; values should be evaluated as & (ie, index.php?cat=6&gal=13&page=1).

Are you experiencing something different? What effect is this having on the rest of your code?

Hi, Jason -

As you can see from the code above, the next/prev links contain multiple ampersands. This has the effect of breaking some of the code on the pages. The $_GET requests seem to fail, for example.

Hi Perch,

Can you click on phpinfo under: Admin > General (at the bottom),
or just use this link: admin.php?menu=admin&action=phpinfo

And let me know what it says for: arg_separator.output

We're using a PHP function called http_build_query() to build urls that uses that value as a separator. My first guess is it has a different value than what is expected (which is &).

Let me know and I'll work on a fix for you. Thanks!

Hi, Dave -

It reads:

arg_separator.input &
arg_separator.output &amp;

Hi Perch,

Try this fix with a recent CMSB version:

- Edit /cmsAdmin/lib/init.php
- Search for: zlib.output_compression
- Add the code in red below the zlib code:

// disable zlib.output_compression so we...
@ini_set('zlib.output_compression', 0);

// Set PHP arg_separator.output value to & so PHP http_build_query() function always works as expected
ini_set('arg_separator.output', '&');

Let me know if that works for you. Thanks!

Hi Perch,

I can imagine why someone might have set it that way, but it wasn't one that we'd see yet. In any case, I've added that patch to the next release. We generally don't workaround PHP configuration issues until problems present themselves.

Hope that helps!
