#22299 closed defect (bug) (invalid)

posts_per_page value in $wp_query does not work in index.php

Reported by: alexvorn2 Owned by:

Component: Query Keywords: close

For example we have only 2 posts.
Using this code to display only one post (title) per page:

$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$args = array(
	'posts_per_page' => 1,
	'paged' => $paged
// The Query
$the_query = new WP_Query( $args );

// The Loop
while ( $the_query->have_posts() ) : $the_query->the_post();
	echo '<li>';
	echo '</li>';

// Reset Post Data

I inserted this in index.php

Going to page/2 will show an error instead of the page 2 (with one post title) of the actual query. I suspect that this is a bug or I missed something?

  • Component changed from General to Query
  • Keywords close added

pre_get_posts hook should be used instead.

See #11067, #16168, #16450, #19463.

Replying to SergeyBiryukov:

pre_get_posts hook should be used instead.

See #11067, #16168, #16450, #19463.

we can use like this

function hwl_home_pagesize( $query ) {
	$query->query_vars['posts_per_page'] = 1;
} add_action('pre_get_posts', 'hwl_home_pagesize', 1);

But this will be like a global function that will apply the same settings to all loops, not good. Why not just update "posts_per_page" option with "1"?

This is a bug 100%

You can add $query->is_main_query() && $query->is_home() check there:

function hwl_home_pagesize( $query ) {
	if ( $query->is_main_query() && $query->is_home() )
		$query->query_vars['posts_per_page'] = 1;
} add_action('pre_get_posts', 'hwl_home_pagesize', 1);

This is actually a support issue.

Thanks! But this does not work for me.

I'm working on a drag and drop feature for a theme, so I'm using wp_query OR query_posts() [for me they are the same] in a widget, that I'm integrating it in the 'general template' that shows in the home and all archives pages.

And in the settings of the widget there is a such option as post per page...
And using an action, seems not a good idea, because I might use TWO or more loops on the same page (divided by different categories)...

Hope a core developer would come to the same problem as I in the near future.

Pagination is calculated before the template is loaded. This is basically the same as using query_posts(), but since you are also altering posts_per_page, then using 'paged' isn't enough, because *total* pages was calculated against the original, main one.
