I want to create a custom category (archive) page for a specific set of categories, adding some querystring vars.
So, I have an url like http://example.com/services/restaurants?city=gotham
If I don't modify WP_Query I have a correct list of services/restaurants but I want to add a filter by city, so if I use WP_Query like this then I get all services (not only restaurants), so it's not working as expected.
This is my code:
<?php
$categories = explode("/", get_query_var('category_name'));
$the_query = new WP_Query(array(
'post_type' => 'services',
'category_and' => $categories,
'meta_query' => [['key' => 'city', 'value' => $_GET['city']]]
)
);
while ( $the_query->have_posts() ) : $the_query->the_post();
?>
<?php the_title(); ?>
<?php
endwhile;
This is showing all services, not only restaurants even $categories is an array with [0] => 'restaurants'.
Note: if I use SAVEQUERIES and print all $wpdb->queries I can see the correct queries are logged, but then, after this queries, other queries for all services are applied.
How can I use WP_Query to get the category marked by url and add my own meta keys?
Thank you.
Just use at top of your archive.php
if( isset( $_GET['city'] && ''!= $_GET['city'] ) {
$city = $_GET['city'];
global $query_string;
$posts = query_posts($query_string."&meta_key=city&meta_value=$city");
}
It will modify the original query and append it

i am trying to get all details of my custom post and print selected data from that on my single-product page.
so lets say the custom post is named Games and the product page is the one were you select on of the games to buy.
i am using:
$args = array(
'post_type' => 'games',
)
);
$review_details = new WP_Query($args);
this is getting me most of the information the product instance, although i chose the post type to be games. since in the post i have the age and rating for the games.
How will I be able to get all the details i already have in the Games Post to the single-product page of a game i am selling?
$args = array(
'post_type' => 'reviews',
'meta_query' => array(
array(
'key' => 'games_books', // name of custom field
'value' => '"' . $game_id . '"', // matches exaclty "123", not just 123. This prevents a match for "1234"
'compare' => 'LIKE'
)
));
$review_details = new WP_Query($args);
print_r($review_details);
and when i use print_r($review_details); all the parameters of reviews are empty, but when i do the same from a post then i can get the reviews.
again i need to print this data on the single-product page
It sounds like you have additional meta information for the Custom Post Type 'games'. Outputting this extra information can be done using either:
get_post_meta($post_id, 'key');
See here for more information https://developer.wordpress.org/reference/functions/get_post_meta/
Or if you're using a common custom field plugin, like ACF, you'll need to use get_field()
get_field('key', $post_id);
See here for more info https://www.advancedcustomfields.com/resources/get_field/
To print a data for custom post, you can use WP_Query with While Option.
For example:
<?php
$args = array( 'post_type' => 'games');
$the_query = new WP_Query( $args );
?>
<?php if ( $the_query->have_posts() ) : ?>
<?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
<!-- Loop Start -->
<?php the_title(); ?>
<!-- Loop End -->
<?php else: endif; ?>
If you want to print custom areas
<?php echo get_post_meta($post->ID, 'key', true); ?>
I have a pretty complicated query that I have not been able to get to work the way I need it to.
I have a Wordpress install using the plugins WP Courseware and ACF. I need to display a page of courses associated with the current user. I want the links to lead the user to the course "home" pages that the user should hit prior to starting the course. I have created course "home" pages, but the problem is WP Courseware has no way to associate a page with a course. So I had to use an ACF options repeater that associates the course ID with whatever course pages are necessary. The only way I know that one of those associated pages is the course "home" page is by the template I use for course home pages.
So the loops within loops need to first determine what courses the current user has access to, get those course IDs, loop the ACF options repeater to find the pages associated with those course IDs, then of those pages loop to find out which one (there is only one per course) uses the course home page template. This last loop I discovered needs to be a WP_Query loop as that's the only way to query for a Wordpress template.
I am lost in loops and I'm having the hardest time. I thought it might be simpler and most direct to use the WP_Query to query an array meta_queries of both the Wordpress template and the ACF repeater (to determine is the ACF repeater course ID matches the course ID the user has access to) but my attempts at querying ACF repeater sub fields is not working.
Here's my code:
$user = wp_get_current_user();
$user_id = $user->ID;
$user_course_list = WPCW_users_getUserCourseList($user_id);
$course_association_arr = get_field('course_association', 'option');
// Loop through user's courses
foreach ( $user_course_list as $user_course ) :
$course_id = $user_course->course_id;
$course_title = $user_course->course_title;
// Loop through the ACF course ID/page associations
foreach ( $course_association_arr as $course_association ) :
$assoc_course_id = $course_association['wp_courseware_id'];
if ( $course_id == $assoc_course_id ) :
// Loop through the ACF associated pages
foreach ( $course_association['associated_pages'] as $associated_page ) :
$page_id = $associated_page->ID;
$page_url = $associated_page->guid;
echo '<li>'. $course_title . '</li>';
endforeach;
endif;
endforeach;
endforeach;
This displays all pages associated with a user's courses, not just the ones using the course home template. I somehow have to incorporate a WP_Query with these args in there and nothing I have done has worked:
$args = array(
'post_type' => 'page',
'meta_query' => array(
array(
'key' => '_wp_page_template',
'value' => 'page-course-home.php',
),
)
);
If I could somehow turn the WP query into an if statement (if template = page-course-home.php) I could have that inside the associated pages query to only show course home pages. Or there maybe another more brilliant way to do what I need to do. I appreciate all feedback.
Ok I got something to work! I think spending so much time framing the question here helped me see one way I could do it:
$user = wp_get_current_user();
$user_id = $user->ID;
$user_course_list = WPCW_users_getUserCourseList($user_id);
$course_association_arr = get_field('course_association', 'option');
// Loop through user's courses
foreach ( $user_course_list as $user_course ) :
$course_id = $user_course->course_id;
$course_title = $user_course->course_title;
// Loop through the ACF course ID/page associations
foreach ( $course_association_arr as $course_association ) :
$assoc_course_id = $course_association['wp_courseware_id'];
if ( $course_id == $assoc_course_id ) :
// Loop through the ACF associated pages
foreach ( $course_association['associated_pages'] as $associated_page ) :
$page_id = $associated_page->ID;
$page_url = $associated_page->guid;
$args = array(
'post_type' => 'page',
'page_id' => $page_id,
'meta_query' => array(
array(
'key' => '_wp_page_template',
'value' => 'page-course-home.php',
),
)
);
$course_assoc_pages = new WP_Query( $args );
if( $course_assoc_pages->have_posts() ) :
while ( $course_assoc_pages->have_posts() ) : $course_assoc_pages->the_post();
echo '<li>'. $course_title . '</li>';
endwhile;
endif;
wp_reset_query();
endforeach;
endif;
endforeach;
endforeach;
This seems a bit cumbersome, but it works. I'm not sure if it would be better but it seems more elegant to incorporate the ACF subfield query into the meta query, so could eliminate two of the loops. If anyone has any thoughts on this I would love to hear them.
I have a custom post type advice and taxonomy adcat. I want to display all post belong to that category.
Lets say I have 4 categories namely : 'games', 'tours', 'dishes', 'hotels' and also this four category is a menu. If I click one of the category for example: hotels all post belong to the hotels should display.
By the way this code I used to show wordpress default categories:
<?php $catname = wp_title('', false); ?>
<?php $posts = get_posts("category_name=$catname&numberposts=8&offset=0");
foreach ($posts as $post) : start_wp(); ?>
//html output
<h1><?php the_title(); ?></h1>
<?php endforeach; ?>
this is not working in custom post 'taxonomies' any suggestion would be helpful thank's
try this maybe it work... I write a note so you can see whats going on.. hope it help
<?php
// Get the term/category of the post
$terms = get_the_terms( $post->ID , 'advice-cat' );
foreach ( $terms as $term ) {
$term_link = get_term_link( $term, 'advice cat' );
}
//WordPress loop for custom post type
$terms = get_the_terms( $post->ID , 'advice-cat' );
$my_query = new WP_Query('post_type=advice&advice-cat=' . $term->name . '&posts_per_page=-1');
while ($my_query->have_posts()) : $my_query->the_post(); ?>
// output content
<?php the_title(); ?>
<?php endwhile; wp_reset_query(); ?>
try something like this, this is the example to fetch post by category id
$args = array( 'cat' => $cat_id, 'post_type' => 'advice', 'posts_per_page' => -1 );
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post();
the_title();
endwhile;
wp_reset_postdata();
you can also use with category name as well.
$args = array('category_name' => 'catname', 'post_type' => 'advice', 'posts_per_page' => -1 );
you can use post_per_page as per your requirement, I have just added -1 for all the posts
I don't really understand your terminology. When you are talking about adcat, is it a custom taxonomy or a term of the build-in taxonomy category. If adcat is a custom taxonomy, you should use the tax_query in WP_Query,not the category parameters.
Remember, category and a custom taxonomy are both taxonomies, their direct children is called terms, and their direct childen is called child terms
You should also not be using wp_title() to get the queries object. You should be using get_query_var() to get the queried object. For categories it will be cat, taxonomy will be taxonomy and for terms term. Have a look at get_categories, get_taxonomies and get_terms for returned values
Example
$category = get_query_var( `cat` );
$cat_slug = $category->slug;
You can now return $cat_slug to your custom query as category_name
EDIT
I've quickly rethinked the whole thing and checked your comment as well. Why not just copy your index.php and rename it taxonomy.php. There is no need at all for a custom query here. The default loop in taxonomy.php should do it
EDIT 2
For further reading, go and check the following articles
Theme Development
Template Hierarchy
Not sure if I read your answer correctly but what I am assuming is you want to search posts by the taxonomy terms correct? So in your adcat taxonomy you have 'games', 'tours', 'dishes', 'hotels' as your terms or categories. Your best option would be to use a tax_query in your query arguments. Here is how to do that with the WP_Query() object.
<?php
$args = array(
'post_type' => 'advice',
'posts_per_page' => 8,
'tax_query' => array(
'taxonomy' => 'adcat',
'terms' => array('games', 'tours', 'dishes', 'hotels'),
'field' => 'slug'
)
);
$query = new WP_Query($args);
if($query->have_posts()) : while($query->have_posts()) : $query->the_post(); ?>
<h1><?php the_title(); ?></h1>
<?php endwhile; endif; ?>
<?php wp_reset_postdata(); ?>
Important Note:
When using a WP_Query you will be overwriting the default post data. So in order to get that data back you just use the wp_reset_postdata() as you can see in the example above after the loop has finished.
I'm sure this is going to be a silly question... but here it goes.
I currently have a page that only displays posts of a Custom Post Type (car).
I do this by running a query
$args = array(
'post_type' => 'car');
$query = new WP_Query( $args );
On to the loop...
For this Custom Post Type i have a Custom Taxonomy e.g. Subaru, Honda etc...
I'm just trying to work something else out, but if I wanted to show only posts that are Subaru's, how would I query that?
I guess I want to query the 'slug' (subaru), this code doesn't work, but you can see the route I was heading...
$args = array(
'name' => 'subaru',
'post_type' => 'car');
$query = new WP_Query( $args );
On to the loop...
I know name isn't right. What is the correct term to add to my $args array?
Many thanks
Depends on what your taxonomy is called. In my example its called 'brands':
$args = array(
'post_type' => 'car',
'brand' => 'subaru'
);
$query = new WP_Query( $args );
see http://codex.wordpress.org/Class_Reference/WP_Query#Taxonomy_Parameters
What you're trying to do is a taxonomy query. I could tell you how to do that but I think it's important I point out a much bigger mistake first. You shouldn't querying this on a page.
That's what archives are for.
Create a template file called archive-car.php and output there instead. That removes the need to run a custom WP Query.
Then create another file taxonomy-{your-custom-taxonomy-name}.php
Output the cars there as well and your problem is solved without adding any inefficient queries.
I think you need to use get_terms()
$terms = get_terms("Subaru");
if ( !empty( $terms ) && !is_wp_error( $terms ) ){
echo "<ul>";
foreach ( $terms as $term ) {
echo "<li>" . $term->name . "</li>";
}
echo "</ul>";
}
See this http://codex.wordpress.org/Function_Reference/get_terms
I am currently working on a personal project and the this page basically has two tabs each will display the archive for specific categories under one custom post type called webinar.
I am calling the category in one of the tabs using
<?php query_posts('category_name=demos-on-demand-videos'); ?>
However when i do this i' just getting the no post's found screen, what am i doing wrong? I am trying to display the post archive from the category demos-on-demand-videos which is under the webinar custom post type.
use this
query_posts( array( 'post_type' => 'webinar','your-custom-taxnomy' => 'demos-on-demand-videos' ) );
while ( have_posts() ) :
the_post();
$post_id = $post->ID;
endwhile;
Follow this link:
http://eyan16.wordpress.com/2013/09/16/how-to-fetch-posts-from-custom-posts-type-with-custom-taxonomy/
Make a page template for each of your tabs and use this custom loop in it. Make sure to adjust it for your specific post type, taxonomy, or term.
<?php $args=array(
'post_type' => 'webinar', //set the post_type to use.
'taxonomy' => 'demos-on-demand-videos', // set the taxonomy to use.
'term' => 'term1', //set which term to use or comment out if not using.
'posts_per_page' => 10 // how many posts or comment out for all.
);
$webinarloop = new WP_Query($args);
if($webinarloop->have_posts()) : while($webinarloop->have_posts()) :
$webinarloop->the_post();
get_template_part( 'content' ); //or whatever method you use for displaying your content.
endwhile; endif; //end the custom post_type loop
?>
This code works for me just fine
* x is taxonomy name name you have created
* y is category slug
$args = array('post_type' => 'client','posts_per_page'=>'8','order'=>'DESC','x'=>'y');
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post();
