I want to exclude a category from my homepage, but my code didn't work:
<?php if( $category_items_query->have_posts() ): ?>
<div class="row columns-layout content-grid">
<?php if( $layout === 'two' ): ?>
<!-- EXCLUDE CATEGORY 17 -->
<?php query_posts($query_string . '&cat=-17'); ?>
<?php while( $category_items_query->have_posts() ): $category_items_query->the_post(); ?>
<div class="col-lg-6 col-md-6 recent-item two-columns post-box">
<?php get_template_part( 'parts/home-content', 'columns' ); ?>
</div><!-- .two-columns -->
<?php endwhile; ?>
<?php endif; ?>
</div><!-- .row -->
<?php endif; ?>
Please help me.
Thanks

Please do not use query_posts as it is ineffiecnt and re-run sql queries and will also mess up your pagination..
Instead use pre_get_posts e.g.
function exclude_category( $query ) {
if ( $query->is_home() && $query->is_main_query() ) {
$query->set( 'cat', '-17' );
}
}
add_action( 'pre_get_posts', 'exclude_category' );
First you must define global variable like below , then you can try your code.
global $query_string;
query_posts($query_string . '&cat=-17');
Also there is another way that you can try as well :
In function.php :
function exclude_category( $wp_query ) {
$excluded = array( '-1' );
$wp_query->set('category__not_in', $excluded);
set_query_var( 'category__not_in', $excluded );
}
add_action( 'pre_get_posts', 'demo_exclude_category' );
In your code (you can use in your way) :
class Exclude_Cat_Plugin {
public function __construct() {
add_action( 'pre_get_posts', array( $this,'exclude_first_category_posts') );
}
public function exclude_first_category_posts( $wp_query ) {
if ( ! is_search() && ! is_archive() ) {
$excluded = array( '-1' );
$wp_query->set( 'category__not_in', $excluded );
set_query_var( 'category__not_in', $excluded );
}
}
}
I hope its help you.

My task is to sort all the custom post types ('audio', 'video', 'webdev' etc.) gathered by taxonomy 'portfolio' or by any tag. And I do it with following code.
add_filter( 'pre_get_posts', 'custom_post_types_sort' );
function custom_post_types_sort( $query ) {
if ( is_tax('portfolio') || is_tag() ) {
$cptui_post_types = cptui_get_post_type_slugs();
// Sort portfolio taxonomy posts by project start date.
$query->set( 'post_type', $cptui_post_types );
$query->set( 'order', 'DESC' );
$query->set( 'orderby', 'meta_value_num' );
$query->set( 'meta_key', 'date' );
}
}
?>
Everything works fine except one thing. My menu not showing on the taxonomy template. I'm using taxonomy-portfolio.php template to display pages.
I assume this is happening because of query modification.
<?php
/**
* Portfolio Taxonomy Template
*/
get_header();
?>
<section class="portfolio-template swiper">
<div class="swiper-wrapper postfolio-list">
<div class="swiper-slide">
<?php get_template_part( 'template-parts/breadcrumbs' ); ?>
<div class="portfolio-project-items">
<?php if ( have_posts() ) : ?>
<?php while ( have_posts() ) : the_post(); ?>
<?php get_template_part( 'template-parts/content', 'portfolio-item' ); ?>
<?php endwhile; ?>
<?php endif; ?>
</div>
</div>
</div>
</section>
<?php get_footer(); ?>
Replace this
if ( is_tax('portfolio') || is_tag() ) {
by this
if ( ( is_tax('portfolio') || is_tag() ) && $query->is_main_query() ) {
Check the docs: https://developer.wordpress.org/reference/functions/is_main_query/
This function is most commonly used within hooks to distinguish
WordPress’ main query (for a page, post, or archive) from a
custom/secondary query.
Does this fix your problem?
Regarding wordpress.org
For the main loop on my homepage I want to display the sticky posts at the top BUT I don't want the post to appear again in the loop, otherwise it appears redundant to the visitor.
Problem with the below code is they remove the sticky post from the top.
I want to KEEP the sticky posts at the top
but REMOVE/EXCLUDE it from the loop. Is this possible?
CODE A: This removes sticky post from top
function mango($query){
if ( $query->is_home() && $query->is_main_query() && !is_admin() ) {
$query->set( 'ignore_sticky_posts', true );
}
}
add_action( 'pre_get_posts', 'mango' );
CODE B: This removes sticky post from both the top AND loop
function mango($query){
if ( $query->is_home() && $query->is_main_query() && !is_admin() ) {
$query->set( 'post__not_in', get_option( 'sticky_posts' ) );
}
}
add_action( 'pre_get_posts', 'mango' );
I think that you must create two loops for this. One for sticky posts and one for regular ones (but exclude sticky posts from second loop). Obviously you must put this code into index.php. Didn't test it but I think it should do the trick...
<?php //we will get "Sticky Posts" only with this loop
$sticky = get_option( 'sticky_posts' );
$args = array(
/* Add whatever you need here - see http://codex.wordpress.org/Class_Reference/WP_Query */
'post__in' => $sticky,
);
$temp = $wp_query;
$wp_query = null;
$wp_query = new WP_Query( $args );
if ( $wp_query->have_posts() ) : ?>
<?php while ( $wp_query->have_posts() ) : $wp_query->the_post();
if ( empty( $sticky ) ) break;
?>
<?php
$wp_query = null;
$wp_query = $temp;
wp_reset_query();
?>
<?php endwhile; ?>
<?php endif; ?><!--END if THE LOOP-->
<?php //Exlude stickies from second loop...
$sticky = get_option( 'sticky_posts' );
$args = array(
'post__not_in' => $sticky,
);
$temp = $wp_query;
$wp_query = null;
$wp_query = new WP_Query( $args );
if ( $wp_query->have_posts() ) : ?>
<?php while ( $wp_query->have_posts() ) : $wp_query->the_post(); ?>
<?php endwhile; ?>
<?php endif; ?><!--END if THE LOOP-->
<?php
$wp_query = null;
$wp_query = $temp;

Im using "insert pages" plugin for wordpress that allows me to insert pages and posts into other pages and posts from the backend. My problem being that when i i use "insert pages" plugin in my news section and then visit the site it shows the shortcode instead of the content. This seems to be a problem only when making a "post". If i use the plugin to display a page within another page it works fine (shows the content not the shortcode).
Any idea what could be the cause of this problem?
Cheers,
Emil
Update

If you've got a small number of posts, the quick and dirty thing to do would be to traverse the loop twice, suppressing zeros on the first pass and suppressing everything except zeros on the second pass:
for ($i=0, $i++, $i<=1) :
while (have_posts()) : the_post();
$show_non_zeros = ($i === 0) && ( get_post_meta( get_the_ID(), 'price', true) > 0);
$show_zero_price = ($i === 1) && ( get_post_meta( get_the_ID(), 'price', true) == 0);
if ($show_non_zeros || $show_zero_price) {
//write output
}
end while;
end for;
If you're looking for a faster / more elegant solution, you can usort() $posts between your call to query_posts and the loop.
hope this will be useful to someone.. i done this way
<?php
/* ADDED by for sorting ASCENDING order but call for price(ie price with 0) last */
function my_sort_custom( $orderby, $query ){
global $wpdb;
$orderby = " case when CAST(meta_value AS SIGNED) = '0' then 1 else 0 end ,CAST(meta_value AS SIGNED) ";
return $orderby;
}
add_filter('posts_orderby','my_sort_custom',10,2);
global $wp_query;
$args = array_merge( $wp_query->query_vars, array('meta_key' => 'price'));
query_posts( $args );
?>
If I want to loop 3 posts from a specific category in index.php of WordPress than what I've to do?
<?php if ( have_posts() ) : ?>
<?php /* Start the Loop */ ?>
<?php while ( have_posts() ) : the_post(); ?>
<?php
get_template_part( 'content', get_post_format() );
?>
<?php endwhile; ?>
<?php the_posts_navigation(); ?>
<?php else : ?>
<?php get_template_part( 'content', 'none' ); ?>
<?php endif; ?>
I want to loop 3 post from a category before <?php get_template_part( 'content', 'none' ); ?>
Try this one
$args = array(
'cat' => <your category ID>,
'posts_per_page' => 3
);
$the_query = new WP_Query( $args );
// The Loop
if ( $the_query->have_posts() ) {
while ( $the_query->have_posts() ) {
// ## write your code here..
}
}
You have to put the category ID.
If you have the category name, then use this:
$args = array(
'category_name' =>
);
For more information check this out:
http://codex.wordpress.org/Class_Reference/WP_Query#Category_Parameters
You can make use of pre_get_posts to alter the main query to get 3 posts from a specific category in the homepage. Add the following to functions.php and be sure to add the category id in the appropriate place
add_action( 'pre_get_posts', function ( $q ) {
if( $q->is_home() && $q->is_main_query() ) {
$q->set( 'cat', CATEGORY_ID );
$q->set( 'posts_per_page', 3 );
}
});
