wordpress query_posts alternative - php

I am creating a website that integrates a portfolio which uses custom post types, this was done based off of this tutorial.
So far it is exactly what I am looking for and works great except for one small detail. In order to fetch the posts from the new custom post type the author of the tutorial used the query_posts() codex. So the top of my portfolio page looks like this:
<?php
/* Template Name: Portfolio */
get_header();
query_posts('post_type=portfolio&posts_per_page=10');
?>
What I gather is that this declares "get posts from "post type" portfolio and show 10 per page". My problem is that I can't go get content from my portfolio page. It seems that now my portfolio page only fetches the content from the custom post type, and I can't use:
<?php while ( have_posts() ) : the_post(); ?>
<?php the_content(); ?>
<?php endwhile; // end of the loop. ?>
to get content from the actual page.
This is what I am trying to do, I've replaced:
query_posts('post_type=portfolio&posts_per_page=10');
with:
add_action( 'pre_get_posts', 'add_my_post_types_to_query' );
function add_my_post_types_to_query( $query ) {
if ( is_page( 8 ) && $query->is_main_query() )
$query->set( 'post_type', array( 'portfolio' ) );
return $query;
}
This seems like the right track, but it stills doesn't work. I'm not getting the posts from my custom post type.
Any ideas how I could modify this? I am also still learning so being clear with explanations would be greatly appreciated.
Thank you!

Editing the pre_get_posts will replace the original query and you will not have the content for your page at all. I would only recommend going this approach if you only wanted to display the content of your portfolio post type and not the content of your portfolio page.
For general post queries it is recommended to use WP_Query or get_posts.
http://codex.wordpress.org/Class_Reference/WP_Query
http://codex.wordpress.org/Template_Tags/get_posts
If you use the WP_Query function the wp_reset_postdata() will restore the post data back to the original so you can get the content of your original page.
$args = array(
'posts_per_page' => 10,
'post_type' => 'portfolio',
);
// The Query
$the_query = new WP_Query( $args );
// The Loop
if ( $the_query->have_posts() ) {
while ( $the_query->have_posts() ) {
$the_query->the_post();
echo '<li>' . get_the_title() . '</li>';
}
} else {
// no posts found
}
/* Restore original Post Data */
wp_reset_postdata();
Now you will be able to use the original loop to show the content of your page
<?php while ( have_posts() ) : the_post(); ?>
<?php the_content(); ?>
<?php endwhile; // end of the loop. ?>

Usually, I stick my query posts in a variable, like so:
$catid = get_cat_ID('My Category Name');
$args = array(
'posts_per_page' => 5,
'orderby' => 'post_date',
'order' => 'DESC',
'post_type' => 'post',
'post_status' => 'publish',
'category' => $catid
);
$posts_array = get_posts($args);
Then you can loop it like so:
<?php foreach ($posts_array as $post) : setup_postdata($post);?>
<h1><?php the_title(); ?></h1>
<p><?php the_content(); ?></p>
<?php endforeach; ?>
Finally, to access your page content you can use the variable $post, it's automatically set by wordpress. No need to add any more code than this to access your page content.
<?php foreach( $posts as $post ) : setup_postdata($post); ?>
<h1><?php the_title(); ?></h1>
<p><?php the_content(); ?></p>
<?php endforeach; ?>
The foreach loop for your page content is a little overkill, and there is a better way to do it (most likely at least), but I haven't been bothered to look into it further yet! It works though!

wp_query pagination on archive.php

I'm using the following wp_query on a few pages in Wordpress, and as you can see I am trying to ensure the query is paginated. Everything is working successfully on a custom page template page-articles.php, however I'm unable to get the same results on the archive.php template.
The pagination link renders successfully (e.g mydomain.com/category/my-cat/page/2) however upon clicking the link does not work, it just throws a 404 error? How can these links not go anywhere?
I'm assuming there is some issue with using custom wp_query on the archive.php template?
Thanks!
Query
$args = array(
'post_type' => 'post',
'posts_per_page' => 1,
'paged' => $paged,
'orderby' => 'date',
'order' => 'DESC'
);
$articles = new WP_Query($args );
?>
Loop
<?php if ( $articles->have_posts() ) : ?>
<?php while ( $articles->have_posts() ) : $articles->the_post(); ?>
Posts here!
<?php endwhile; ?>
<?php wp_reset_postdata(); ?>
<?php endif; ?>
Pagination
<nav>
<div class="prev"><?php echo get_previous_posts_link( 'Previous', $articles->max_num_pages ); ?></div>
<div class="next"><?php echo get_next_posts_link( 'Next', $articles->max_num_pages ); ?></div>
</nav>
After a bit of digging around, and with help from this article, the below solution solves the issue. Just place this in your functions.php file and thats it. The below implementation works for archives of custom post types, as well as categories.
/**
* Wordpress has a known bug with the posts_per_page value and overriding it using
* query_posts. The result is that although the number of allowed posts_per_page
* is abided by on the first page, subsequent pages give a 404 error and act as if
* there are no more custom post type posts to show and thus gives a 404 error.
*
* This fix is a nicer alternative to setting the blog pages show at most value in the
* WP Admin reading options screen to a low value like 1.
*
*/
function custom_posts_per_page( $query ) {
if ( $query->is_archive('cpt_name') || $query->is_category() ) {
set_query_var('posts_per_page', 1);
}
}
add_action( 'pre_get_posts', 'custom_posts_per_page' );
Yes, it is.
It is because main query of archive.php is kept unchanged while you are playing with WP_QUERY. Try use query_posts() in archive.php.
query_posts($args);
and then default loop (instead of $articles)
<?php if ( have_posts() ) : ?>
<?php while (have_posts() ) : the_post(); ?>
Posts here!
<?php endwhile; ?>
<?php wp_reset_postdata(); ?>
<?php endif; ?>

wordpress php loop - archive is looping the same number of times as results

Not sure that's the best way to to describe it, but here's what's happening (and I'm sure this has to be a reasonably easy thing, just not sure where to look):
Client has 10 offices so I'm using the Advanced Custom Fields plugin with a custom post type to specify a location for job postings. My code seems to be working (i.e. it's pulling the appropriate jobs by location) but it's looping the article tag the same number of times as results. I have 3 jobs in there, so it loops the whole set of results 3 times. If I delete one and drop down to 2, it loops twice, etc. I used the following example from the advanced custom fields website:
<?php
// args
$args = array(
'numberposts' => -1,
'post_type' => 'jobs',
'meta_key' => 'location',
'meta_value' => 'akron'
);
// query
$the_query = new WP_Query( $args );
?>
<?php if( $the_query->have_posts() ): ?>
<h3>Akron Office</h3>
<ul>
<?php while( $the_query->have_posts() ) : $the_query->the_post(); ?>
<li> <?php the_title(); ?></li>
<?php endwhile; ?>
</ul>
<?php endif; ?>
<?php wp_reset_query(); // Restore global post data stomped by the_post(). ?>
I guess I'm not sure where to look (I realize this might be a plugin question rather than a php question) and would appreciate any direction you guys can provide.
You can see the offending page here: http://www.knrlegal.com/jobs/
You should reset the post data, not the query, as stated here:
Class Reference/WP Query, in the "Multiple Loops" section.
<?php
// args
$args = array(
'numberposts' => -1,
'post_type' => 'jobs',
'meta_key' => 'location',
'meta_value' => 'akron'
);
// query
$the_query = new WP_Query( $args );
?>
<?php if( $the_query->have_posts() ): ?>
<h3>Akron Office</h3>
<ul>
<?php while( $the_query->have_posts() ) : $the_query->the_post(); ?>
<li> <?php the_title(); ?></li>
<?php endwhile; ?>
</ul>
<?php
/* Restore original Post Data
* NB: Because we are using new WP_Query we aren't stomping on the
* original $wp_query and it does not need to be reset with
* wp_reset_query(). We just need to set the post data back up with
* wp_reset_postdata().
*/
wp_reset_postdata();
?>
<?php endif; ?>

Wordpress Custom Loop doesn't show any posts

I'm trying to add a custom loop to display post titles from the category homepage. Here's the code I have so far so, but it's not displaying any posts. BTW, I'm using this code in single.php.
<?php $recentPosts = new WP_Query(); ?>
<?php if ( $recentPosts->have_posts() ) : ?>
<?php $recentPosts->query_posts( array ( 'category_name' => 'homepage', 'posts_per_page' => 10 ) ); ?>
<?php while ($recentPosts->have_posts()) : $recentPosts->the_post(); ?>
<h2><?php the_title(); ?></h2>
<?php endwhile; ?>
<?php endif; ?>
<?php wp_reset_postdata(); ?>
I'm not too sure what's going on, but would appreciate any help I can get.
You're doing a lot of unnecessary messing around with your query object. Since you're dealing with an archive page, you should be able to create a new template file called category-homepage.php (assuming the slug of the category is homepage). In it, you could place something like the following:
$args = array(
'category_name' => 'homepage',
'posts_per_page' => 10
);
$recentPosts = new WP_Query( $args );
if ( $recentPosts->have_posts() ) :
while ( $recentPosts->have_posts() ) : $recentPosts->the_post(); ?>
<h2><?php the_title(); ?></h2>
<?php endwhile; endif; ?>
Again, since it's a category archive page, you shouldn't be doing anything to single.php. You can read more about template hierarchy in the Codex.

Show category name above category posts

I'm trying to get the category name to show above posts. I'm customizing bones and am a little stuck.
Here's the code that has my posts displaying, and I have each in a category in the wp admin. I'm just not sure how to get the category to display above the appropriate posts.
Hope this makes sense. Thanks in advance!!
<?php
$args = array( 'post_type' => 'custom_type', 'posts_per_page' => 100 );
$the_query = new WP_Query( $args );
?>
<?php if ( $the_query->have_posts() ) { ?>
<?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
<h2><?php the_title(); ?></h2>
<div class="entry-content">
<?php the_content(); ?>
</div>
<?php endwhile; ?>
<?php wp_reset_postdata(); ?>
<?php } else { ?>
<p><?php _e( 'Sorry, no posts matched your criteria.' ); ?></p>
<?php } ?>
It looks like you are doing a custom loop (as opposed to "The loop"), hence you'll need to pass the id of the post to get_the_category. However, judging by the docs, it seems that WP_Query->the_post() sets the global post.
So, if this does not work:
<h2><?php echo get_the_category() ?></h2>
You would do:
$postsQuery = new WP_Query( $args );
$posts = $postQuery->get_posts();
foreach ( $posts as $i => $e ) {
$category = get_the_category($e->ID);
}
https://developer.wordpress.org/reference/functions/get_the_category/
https://codex.wordpress.org/Class_Reference/WP_Query
https://codex.wordpress.org/The_Loop
You can use like <?php the_category();?>. This will returns the categories name with link. Hope this help you!
Hi I could not post in comments, but if above answer is working for you as you posted in comments but having issue with getting category as it give array due to many categories of a post, so you need to fetch first category from the array. Use below code snippet:
if ( ! empty( $category ) ) {
echo '' . esc_html( $category[0]->name ) . '';
}

How to display more listings in WordPress

I'm having an issue with the listings in the WordPress site I'm working on.
I have three listings only showing up out of 6. I can't seem to figure out how to make all of them display. This is using the twentyeleven WordPress theme.
The arrows on the right are used to move the gallery back and forth. Only one more shows up on the right side.
Here's the code I believe is generating it.
<?php if ( have_posts() ) : ?>
<?php twentyeleven_content_nav( 'nav-above' ); ?>
<?php if ( is_home() ) {
query_posts($query_string . '&cat=-3');
}
?>
<?php
$page_name="Articles";
$page=get_page_by_title($page_name);
//echo $page->ID;
query_posts( 'cat=-1,-2' );
?>
<?php /* Start the Loop */ ?>
<?php while ( have_posts() ) : the_post(); ?>
<?php get_template_part( 'content', get_post_format() ); ?>
<?php endwhile; ?>
</div>
Any help would be great, thanks.
Change your query_posts() function to the following:
query_posts( 'cat=-1,-2&posts_per_page=6' ); // You can change the post_per_page variable as needed
However, I would suggest using an $args array instead of a querystring to make your query. The same query would look like this:
$args = array(
'cat' => array( -1, -2 ),
'posts_per_page' => 6
);
query_posts($args);
It is much more readable and easier to update. Also, it's worth mentioning, you are adding a negative operator to your categories. In the query_posts function, that will exclude a category. You may only be getting 3 posts because you are excluding posts from your query.
