Problem with Pagination

[CodeCoffeeCode]

Hi fellow PW people.

This is my 1st time posting here. Being a html and css front-end guy I’m virgin to CMS development but picking up the art of programming fast thanks the user intuitive and friendly ProcessWire which ended up being my CMS of choice after a month of experimenting among several.

I’ve finally been presented with my first ‘unable to figure out’ problem… 

Ive been trying to tackle my head around a pagination problem. I am able to output the pagination however when you click on ‘page 2’ it directs to that page in the url, but the results don’t update. 'Page 2' outputs the results of 'page 1'. Also the navigation link stays on 'page 1' and the previous button don’t show.

I have read through the API docs and also consulted other forum posts relating to pagination, trying out various different options to no avail. 

I have also enabled pagination in the templates used by the output pages. So I’m left scratching my head hoping some clever PW pro can help me figure this out. Below is the code used for the output.

<?php foreach($results = $page->children("limit=6") as $child) 
echo "
  <div class=\"cottage-listing\">
    <div class=\"image\">
      <img src=\"{$config->urls->templates}/styles/images/examplecottage.jpg\" alt=\"Image of [cottage_name], [cottage_area]\">
    </div> 
    <div class=\"description\">
      <p>
      <span class=\"cottage\"><strong>$child->title </strong>$page->title, {$page->parent->title} </span>
      <span class=\"information\">[cottage_summary] - Limited to 120 Chars</span>
      </p>
    </div>
    <div class=\"info\">
      <span class=\"price\"><strong>from: £121</strong>per night</span>
      <dl>
        <dt>Type: </dt>
        <dd>{$child->cottage_type->title} | {$child->cottage_catering->title}</dd>
        <dt>Sleeps:</dt>
        <dd>{$child->cottage_sleeps}</dd>
        <dt>Rooms:</dt>
        <dd>{$child->cottage_bedrooms}</dd>
      </dl>
      <a href=\"{$child->url}\" class=\"button\">More Details</a>
    </div>
  </div>
";  ?> 

<?php 
$pagination = $results->renderPager(array(
// Controls the output of the pagination links
    'nextItemLabel' => "»",
    'nextItemClass' => "",
    'previousItemLabel' => "«",
    'previousItemClass' => "",
    'listMarkup' => "<ul class='pagination'>{out}</ul>",
    'itemMarkup' => "<li class='{class}'>{out}</li>",
    'linkMarkup' => "<a href='{url}'>{out}</a>",
    'currentItemClass' => "current",
    'firstItemClass' => "",
    'firstNumberItemClass' => "",
    'lastNumberItemClass' => "",
    'lastItemClass' => ""
));
if ($pagination ==""){
  echo ""; } 
else {
  echo "<div class=\"pagination-centered\"> $pagination</div>";
}
?>

Any suggestions are welcome. It is probably something stupid staring me in my face, but after several hours trying to figure it out myself I'm turning to the super supportive forum before I start pulling my hair out (what's left of it) .

Sorry to be a bit picky, but I cannot find any issue with your code, so we check this:

I have also enabled pagination in the templates used by the output pages. 

Do you mean by "output pages" the children you're showing in the list? This would be wrong. You'd need to enable pagination on the template where you're rendering the list, not in the template of the list-items. The setting just enables, that ProcessWire parses the urlSegments correctly, this has nothing to do with the paginated content.

[CodeCoffeeCode]

Hi LostKobrakai,

Yeah, I have enabled pagination on the template where I am rendering the list. Exactly as has been discussed in other pagination discussions. That's why I'm puzzled about this. 

[Soma]

What's the url when you go to page 2?

Is there something else special in your setup?

Otherwise I would say pagination is not enabled or you have other limit calls previously in your code.

[CodeCoffeeCode]

Hi Soma,

The URL when I go to page-2 is: " http://localhost:8888/LDVC-PW-DEV/adult/child/?page=2

There is nothing special in my setup. I'm basically running the  Latest PW Dev version with basic installation and one site module (ProcessPageFieldSelectCreator).

Pagination is certainly enabled on the template used to render the lists:

And in regards to other limit calls previously in my code, I don't think there was any.

I have actually spent all day just trying to get my head around this... Including creating a new PW installation importing my template files and fields from the default. Enabling pagination in the templates... But it still does not work.

[LostKobrakai]

Pagination is done by urlsegments so the url shouldn't have get strings, but rather an …/page2/ at the end of the url. And just to quote Ryan on that (comment on the pagination docs)

If you are seeing a URL like ?page=2 that indicates that pagination is not enabled for the template, and you would need to enable it.

[Soma]

Only thing I can say is that /adult/child/?page=2

Actually

/child/?page=2

indicates that pagination is NOT enabled on the page you are on doing it, if it was it would be

/child/page2

LostKobrakai,

Okidoki, Just to prove to myself that I am not going insane, here is proof that I have the template set up so pagination is enabled. Forgive me if I am wrong, but Im 100% confident that this is all set up properly and the template is using the code I originally posted here. Unless I'm seriously missing something here.

Image one: Proves the core plugin is installed:

Image two: Proves the template "location.php" has pagination enabled:

Image three: Proves the template "location.php" is in use for the list results... with pagination enabled.

In image 3, you can see it outputs the page template being used. You can also see that the Pagination Numbers are output to the page, and also that in the url it shows "foo/bar/?2".  If i click on the number one, it redirects the URL to "foo/bar/".  

I also tried limiting the pagination to return only 1 result per page, resulting on numbers 1,2,3,4 output to the pagination as there are only 4 sample child pages. And the same result applies when clicking on either of the numbers; it returns the numbers in the URL but not the results.

So am I missing something stupidly simple and basic here? I'm fairly certain I have done things correct but then again, my brain is almost in zombie state spending too much time trying to figure out this issue.

I doubt that this is the problem, but anyway: Do you use some sort of cache (Templates cache, Markup Cache, ProCache) ? Maybe you see a cached version of the page.

[CodeCoffeeCode]

Hi Wanze,

Ive not enabled any catching modules yet to my knowledge. Im going to double check everything now to ensure caching is off on all templates. Ive not installed any site modules for caching anything yet. I'll also clear my browser history and check the page in multiple browsers.

[Soma]

Location template aren't the items you want to paginated aren't they?

Is location template = central-lakes or ambleside ?

[CodeCoffeeCode]

Soma,

Yes, I want the children of this template to be paginated. I also what the child pages of the next level paginated... My Page structure is:

region template = central-lakes

location template = ambleside

HOME - ( home template )

- Region 1 ( region template ) paginates child pages ( Locations )

-- Location 1 ( location template ) paginates child pages (cottages)

--- Cottage 1 ( cottage template )

--- Cottage 2 ( cottage template )

--- Cottage 3 ( cottage template )

--- Cottage 4 ( cottage template ) 

-- Location 2 ( location template ) paginates child pages (cottages)
--- Cottage 1 ( cottage template )
--- Cottage 2 ( cottage template )
--- Cottage 3 ( cottage template )
--- Cottage 4 ( cottage template )

The code I originally posted represents this, (i think).

[Soma]

What do you get if you add this to your code just before foreach?

echo "pagenum: " . $page->template->allowPageNum;

[CodeCoffeeCode]

Soma, I get: "pagenum: 0"

[Soma]

That means that the page you're looking at, its template doesn't have page numbers enabled.

Can you change it to this?

echo "template: " . $page->template->name . " pagenum: " . $page->template->allowPageNum;

[CodeCoffeeCode]

Soma, I now get :"template: cottage pagenum: 0"

But I don't understand why, because this pages template is set to "location" see screenshot below:

[LostKobrakai]

Do you have any custom or 3rd party modules installed and if so which ones? 

[CodeCoffeeCode]

Soma,

Custom modules: I only have the "Page Field Select Creator" Module installed...

[Soma]

Maybe you should show us all template code...

You either have a $page = $somethingElse overwriting current page. Or you render the page from another page.

[CodeCoffeeCode]

Here is the complete code for the "location: template: 

Removed code as I fixed the problem, and it was not with the code in this post

Soma, LostKobrakai, Wanze

Many thanks for your time helping me try to figure this out... I did a fresh install of PW and imported the templates and fields (not including the cottage template). When I attempted to create a "region" page using the region template, I was thrown this error:

Error #2 is what was causing the problem!!!! 

As it happens I had this line of code in my "head" template (TMP_head.inc):

<div id="wrapper" <?php if ($page->template = cottage): echo 'class="cottage-listings"'?> <?php endif ?>>

When it should have been:

<div id="wrapper" <?php if($page->template == location) echo 'class="cottage-listings"'?>>

What an idiot I am  ...  Thank you all once again for your assistance and support.

[Soma]

Then your

<h1><?php echo $page->title; "Holiday Cottages"; if($page->editable()) echo "<p><a href='$page->editURL'>Edit</a></p>"; ?></h1>

also outputs title of cottage and edit link?

It's like you overwrite $page somewhere (header.inc?) or just the template like $page->template = "something" instead of $page->template == "cottage" ...

Strange, and I don't see what's wrong. Only thing I know is that you're viewing a page that template doesn't have pagination enabled.

Yes, it was a problem with the code in my head.inc template... Sorry for taking your time to help me with this, as it was such a stupid and simple issue that should not have happened if I had been paying more attention to what I was trying to do... Lesson Learnt!! Many thanks

Don't worry, we've all been in this situation before
