Make pagingation works on custom post type archive

[Grégoire Noyelle]

Hi

I need to have a custom loop custom post type (CPT) archive with pagination.
On the CPT, I have activate genesis archive support. The loop wooks but for the pagination on page 2, I get a 404.

Here is my code for the archive-cpt.php file:

<?php
// custom loop for cpt archive

remove_action( 'genesis_loop', 'genesis_do_loop');
add_action('genesis_loop','gn_loop_event');
function gn_loop_event() {
	$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
	$args = array(
		'post_type' => 'gnpost_evenement',
		'posts_per_page' => 4,
		'paged' => $paged
	);
	global $wp_query;
	$wp_query = new WP_Query( $args );

	if (have_posts() ) :
		while ( have_posts() ) : the_post();
			$boucle = new BBPostEvent('event-grid');

		endwhile;
		do_action( 'genesis_after_endwhile' );
		wp_reset_query();
	endif;

} // function gn_loop_event()

genesis();

Notes:
the $boucle variable display all the element of the class
And the site is closed. You can use
id: visit
psw: visit

Could you help me?

Thanks
Grégoire

I forget to mention that the real name of the custom archive page is : archive-gnpost_evenement.php

Cou can try to first remove the Genesis pagination and later hook it in again.

Try this - before the remove loop stuff:

/** Remove Genesis pagination - only use pagination on custom loop */
remove_action( 'genesis_after_endwhile', 'genesis_posts_nav' );

Then re-hook it below in your code - try the proper position before or after endif or reset query:

/** Genesis navigation */
genesis_posts_nav();

This thing is untested with your code, but I had similar issues with a page template once...

Hi Dave
Thanks a lot. Good to see you here 🙂

I try but It do not work. And I want to avoid a custom page template for that.
I wonder if it comes from the archive-gnpost_evenement.php (archive-$posttype.php) template?

Cheers

[David Decker]

What does if you try directly: 'paged' => get_query_var( 'paged' ) ?

Have you tried flushing the WordPress rewrite rules by going to Settings > Permalinks and clicking the "Save Changes" button? Sometimes that is required to get pagination to work with custom post types.

[Grégoire Noyelle]

@david-decker Same result

@Nick Thanks for the help. That's the first thing I make 🙂

[Grégoire Noyelle]

I do think that's a conflict with the archive-$posttype.php model.

I made a lot of genesis custom loop in custom template and It works perfect. But now I need to have more logical url and use the custom post type archive model without creating a new page.

[Nick]

Could it be related to this issue here, perhaps? https://wordpress.org/support/topic/explanation-and-workaround-for-error-404-on-category-pagination?replies=10

If you set Settings > Reading > Blog pages show at most to "1", does the problem go away? http://d.pr/i/1334r

[Grégoire Noyelle]

Thanks a lot @Nick

I just have 20 post on this custom post type and the general setting for Setting > Reading was on 24. You're right 🙂
But to make it works, i have to change the orderby parameter and remove paged parameter and add it again.
And If I try to put Setting > Reading on 18, the pagination still works except for the last one, I get a 404.

Finaly It always works if I put Setting > Reading on 1. But that's not the good solution for all the website archive.

Really odd. It seems to be very unstable. I hope to find a better solution to handle it.

[Grégoire Noyelle]

With a custom template and the exact same $wp_query, I have no problem at all but for me the URL result is just so "bad" and you need a blanck page.
What a shame like genesis support genesis-cpt-archives-settings

[Nick]

Does it work if you use the pre_get_posts filter in your template? Something like this before your main loop function:

add_filter( 'pre_get_posts', 'my_archive_query' );
function my_archive_query( $query ) {
    $query->set( 'posts_per_page', 20 );
}

(You could then remove the 'posts_per_page' parameter from the array in your main loop.)

There's an interesting WordPress trac ticket here that you may like to read: https://core.trac.wordpress.org/ticket/16168 It suggests that pagination in archive template loops only works if the query is modified using the pre_get_posts filter.

[Grégoire Noyelle]

Good catch Nick. Thanks a lot to take the time for that.
I try, and it change nothing. The only case which works perfect is when I set up Settings > Reading > Blog pages show at most to “1″
Not really usefull for all the other archive page.

[Grégoire Noyelle]

I try to make a page with a custom template with the same loop and the same slug as CPT gnpost_evenement.
But even, if I delete the file archive-gnpost_evenement.php (archive-$posttype.php) the theme take the index.php file as template and note the page 🙁

[Genesis Developer]

try this once

<?php
// custom loop for cpt archive

remove_action( 'genesis_loop', 'genesis_do_loop');
add_action('genesis_loop','gn_loop_event');
function gn_loop_event() {
	$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
	$args = array(
		'post_type' => 'gnpost_evenement',
		'posts_per_page' => 4,
		'paged' => $paged
	);
	global $wp_query;
	$wp_query = new WP_Query( $args );

	if (have_posts() ) :
		while ( have_posts() ) : the_post();
			$boucle = new BBPostEvent('event-grid');

		endwhile;
		do_action( 'genesis_after_endwhile' );
	endif;
        wp_reset_query();
} // function gn_loop_event()

genesis();

thanks @genwrock I try but it change nothing.

I make some other tests today.

* I swich to genesis sample to be sure to not influence the theme with other actions
* I add the same archirve-$posttype.php with custom in genesis sample (all the CPT are made with a home made plugin)
* I try pagination as before and I get the same bugs. 404, problem if Settings > Reading > number is more important thant the total of CPT
* If I remove the custom loop, everything is normal

I don't know if this is a Genesis Bug or WordPress one. But that anoying.

It will be ok, if I can use a page with the same slug (thant the cpt archive) to make a custom loop. But as I said, If I delete the archirve-$posttype.php, that's the index.php which have stronger priority.

[Grégoire Noyelle]

Hi
I find the solution. It works great even if the setting for archive is more important than the number of CPT.
I hope It can help.

Here is the solution:

For the CPT (gnpost_evenement) archive page (archive-gnpost_evenement.php) I put:

<?php
// custom loop for cpt archive

remove_action( 'genesis_loop', 'genesis_do_loop');
add_action('genesis_loop','gn_loop_event');
function gn_loop_event() {
	$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
	$args = array(
		'post_type' => 'gnpost_evenement',
		'orderby' => 'title',
		'order' => 'DESC',
		'paged' => $paged
	);
	global $wp_query;
	$wp_query = new WP_Query( $args );

	if (have_posts() ) :
		while ( have_posts() ) : the_post();
			$boucle = new BBPostEvent('event-grid');

		endwhile;
		do_action( 'genesis_after_endwhile' );
		wp_reset_query();
	endif;

} // function gn_loop_event()

genesis();

The difference here is that I do not put the posts_per_page parameter. For that I use a plugin OR the functions.php to make some filter. To make it works, you have to fire up this before caling the template file.

// Filter for custom post type gnpost_evenement
add_filter( 'pre_get_posts', 'gn_event_archive_filter' );
function gn_event_archive_filter( $query ) {
	if ( $query->is_post_type_archive( 'gnpost_evenement' ) ) :
    	$query->set( 'posts_per_page', 4 );
    endif;
}

Special thanks to @david-decker, @Nick and @genwrock

[Nick]

Yep, it looks like filtering the posts_per_page in pre_get_posts is the way to do it! Well done for your perseverance, thanks for posting your solution, and I'm really happy that you managed to solve it!

[Grégoire Noyelle]

Thanks @Nick . You give me the idea about pre_get_posts 🙂
It's opens so many possibilities about CPT archive page with a clean URL
