at the moment I am querying out all pages that I have in WordPress and am displaying them on a page. Like this:
<?php
query_posts(array('post_type' => 'page'));
while(have_posts())
{
$this_page = the_post();
echo the_content();
}
?>
The question is, how can I do the same thing but just for one specific post? As a side note, if I need to use id's of pages where can I find them, as at the moment I don't see what id page has in WordPress.
take a look at the page on query_posts in the wordpress codex here: http://codex.wordpress.org/Function_Reference/query_posts .
Adjust arguments accordingly. For example, to query a post with a specific id:
query_posts( 'p=5' );
something like this?
query_posts( array ( 'category_name' => 'my-category-slug', 'posts_per_page' => -1 ) );//al items from my-category-slug
while(have_posts())
{
$this_page = the_post();
echo the_content();
}

I'm running Wordpress 4.1. I have two blog pages on my site, and though I don't really know php, I've done some tinkering and figured out how to modify the page templates so each page only displays posts for a specific category. That bit of code looks like this:
<?php query_posts('cat=2'); ?>
That works fine. Page A displays posts from category 1, and Page B displays posts from category 2.
What I'd like to do is disable post title links for one specific category. In other words, Page A would display posts from category 1 (with standard clickable title links), and while Page B would display posts from category 2 (with non-clickable title links).
I'm an HTML/CSS guy, so really out of my depth here, but if there's a way to modify the loop to achieve this, I'd love to learn how. Thanks in advance for any help.
Yes, you can do this using the category.php theme file. When this page is hit, it loads a specific category requested and the posts that fall into that category.
Your theme and loop may look something like this:
<?php single_cat_title(); ?>
<?php echo category_description(); ?>
if (have_posts()) : while (have_posts()) : the_post();
/// display posts from specific category
endwhile; endif;
Or if you don't want to use that page which is designed for that, you can create your own loop:
query_posts( array ( 'category_name' => 'my-category-slug', 'posts_per_page' => 50 ) );
All together like this:
<?php
/* retrieve unlimited # of posts with an category slug of music */
query_posts( array ( 'category_name' => 'music', 'posts_per_page' => -1 ) );
// set $more to 0 in order to only get the first part of the post
global $more;
$more = 0;
// the Loop
while (have_posts()) : the_post();
the_content( 'Read the full post »' );
endwhile;
?>
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!
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.
I created a new template in Wordpress to show the latest articles. After, I will sort them in other ways. My problem is I can not use the pagination correctly.
The next page and previous page are working ok, but the posts are not changed. The first three are the only that are shown.
Can you give me a clue about this ?
<?php
/*
Template Name: Latest Prizes
*/
get_header();
// The Query
query_posts( 'posts_per_page=3' );
// The Loop
while ( have_posts() ) : the_post();
echo '<li>';
the_title();
echo '</li>';
endwhile;
posts_nav_link(' · ', 'previous page', 'next page');
// Reset Query
wp_reset_query();
get_footer(); ?>
From the Wordpress Codex on query_posts():
...
For example, on the homepage, you would normally see the latest 10 posts. If you want to show only 5 posts (and don't care about pagination), you can use query_posts() like so:
query_posts( 'posts_per_page=5' );
Change your query_posts() to this:
query_posts(array('posts_per_page' => 3, 'paged' => get_query_var('page')));
Hello I want to Create a home page that has updating blog entries.
So 4 lists of headlines from different categories
And I want to have a link to the regular blog page with a different template.
Right now I just changed index.php around to have the containers for the featured posts content.
So this is a two part question how do I get these mini updates for the thing
I want to use query_posts() multiple times I assume and separate by category.
And how do I make a linkable page to a blog.php file which currently is telling me that all these functions are undefined.
<?php get_header(); ?>
<?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 endif; ?>
<?php get_footer(); ?>
If you want to create a page that includes WP data/posts outside the themes or blog folder, you need to include and make available the Wordpress functions first:
define('WP_USE_THEMES', false);
require('./blog/wp-blog-header.php');
And then you can make the queries for each set of posts by category:
$args = array( 'numberposts' => '5, 'offset'=> 1, 'category' => 'your category ID' );
$myposts = get_posts( $args );
foreach($myposts as $post) {
...some code...
}
I hope it helps.
