I'd like to implement a custom post retrieval page in wordpress. Basically, I'm using AJAX to call this page that will be passed a post ID and retrieve certain data from that post.
Note: please don't mistake this as a template question. I do not want a template for one single page -- I am looking to make this page query multiple different posts based on postID and return certain data from that post.
So I tried creating a page
<?php
$args=array(
'p'=>'77'
);
$friends = new WP_Query($args);
?>
<?php if ($friends->have_posts()) : the_post(); ?>
<?php the_title(); ?>
<?php the_content(); ?>
<?php else: ?>
<p>Sorry, no posts are available.</p>
<?php endif; ?>
But this does not work since it is not loading in the wp functions to handle the query.
Thanks in advance for any help!
You have to include the wp-blog-header.php file. If the page you are creating is in your theme's folder then you would put something like this at the top of your code
<?php require_once ('../../../wp-blog-header.php');?>
I think I guess what you are trying to do, and it sounds like you are going about it the wrong way. Do not make a 'new page' in the admin interface. What you want to do is serve up a file (JSON, XHTML fragment, whatever) to your Javascript and include in it WP data, right? I know that problem, having used it in some of my plugins.
There are two techniques:
(1) This is what you need to do: make a new plugin (just a loose php file in wp-plugins with the same format header as the other plugins in there). Write your function along these lines:
function mydatapage(){
if (...$_SERVER['REQUEST_URI'] == the one I am using ...) {
$args=array(
'p'=>'77'
);
$friends = new WP_Query($args);
if ($friends->have_posts()) :
the_post();
the_title();
the_content();
else:>?
<p>Sorry, no posts are available.</p>
<?php endif;
die();
} //else do nothing and leave WP to serve the page normally
}
//Crucially:
add_action('init', 'mydatapage');
What that does is do a lookup when pages are loaded to see if the url matches the one you want to hijack and use to send your custom data. If it is, you send the data/file/whatever you feel like and exit (die).
Give a shout if you want more detailed syntax. It is a bit messy, but works well.
(2) Directly call your plugin file. WP will only handle files that do not already exist, and leave the rest to Apache. That means you can make a plugin file and call that directly using the .../wp-plugin/myfile.php url. You would need to include some of the WP core files to get things like WP_Query to work. It is marginally more fragile a method.

I'm creating my first wordpress theme, and I've looked around on google, and the wordpress codex for an answer to my question, but I can't seem to find exactly what I'm looking for, or couldn't get it working.
What I'm trying to do, or trying to figure out, is how I can make it so a certain category has a certain design.
So if I wanted to make an index.php for any music videos in "www.domain.com/music/trash/drake-song.mp4.html"
the trash category, it'd have its own design, but songs in
"www.domain.com/music/good-music/coldplay-viva-la-vida.mp4.html"
the good-music category, I want it to look pretty much completely different. I've tried using something similar inside my header.php to this;
<?php
if( is_tag( 'good-music' ) ):
$my_classes = array( 'good-class', 'good-class-two' );
else:
$my_classes = array( 'not-good-class' );
endif;_
?>
but it seemed to simply change the category page.
"www.domain.com/categories/good-music"
Anyone know what I could be doing wrong? I know basic html/css/php/javascript, new to creating a WordPress theme, and can't seem to get this working..
Also:
Using XAMPP to host locally, using Friendly URL's, properly configured
In order to generate category-specific markup for a single post layout, you can put code like the below in your single.php file after the call of get_header().
Please note that this checks for your category based upon category slug. So if your category slug (the url version of your category) does not match the first arguments in the in_array() function call below, then you should change the argument to match the slug for your category.
<?php
/* Start the Loop */
while ( have_posts() ) : the_post();
?>
<?php
$categories = get_the_category();
$catSlugs = array();
foreach ($categories as $category){
$catSlugs[] = $category->slug;
}
if (in_array('good-music',$catSlugs)){
$post_cat = 'good-music';
} else {
$post_cat = 'not-good-music';
}
get_template_part( 'template-parts/post/content', $post_cat );
?>
<?php
endwhile; // End of the loop.
?>
It is important that this code only appear where there is a query to loop against.
Specifically, the file single.php in your theme should be the default file for displaying a single post, regardless of category. When you navigate to the url of a single post, this layout should be triggered.
As part of that triggering, a wordpress query of just that post is returned to be looped through.
Then, the code from while ( have_posts() ) : the_post(); until endwhile; will run one time, because there is a single post to be processed.
If there were more than one post, such as on a category page or on your default post listing page, then the code inside of that while loop would run as many times as there are posts in the query for that layout.
If you were to place the code in the header, it won't work because the header is prepared independently of the loop that runs on this page.
You could run a custom WP_query() in the header, but that is rarely a good way to handle site content.
In this situation it would not be appropriate, because you are customizing content of existing posts, and only differentiating based upon category.
So, just use the standard layouts files with custom layout parts.
I stripped out the divs in the loop below, because you may or may not be using bootstrap.
After this code is placed on your page, you would create files called content-good-music.php and content-not-good-music.php in YOUR_THEME_DIR/template-parts/post/ directory. The key is that you would add whatever your category slug is to the end of your
These files will contain the unique markup for these kinds of posts. You can also use a similar logic in your post listing loop to give the listed posts for each category their own unique php files.
Here's some get_template_part() documentation.

I am looking for some sage advice on how to best create a page/slug structure for a WP site I am building. It is a portfolio site that will showcase creative work. I have currently created several custom post types for things such as the portfolio/work items and for their associated clients and have created relationships between those items using the Advanced Custom Fields Plugin. All of this works great. What I am struggling with is how to create the best URL structure.
I have the following pages already created and working well:
/work/ - index page that shows all work regardless of client
/clients/ - list of all clients
I need to create the following pages:
/clients/client/ - this page would show all work associated with a specific client. Here is where I am struggling. I need help understanding how to use the page template system to set the correct page slugs. Can I use page slugs as part of my WP query? Can I simply query based on the custom post type? What do I name the page template file for this to work?
Appreciate any advice and/or examples anyone can offer. Thank you.
WordPress offers an easy mechanism to handle pages and posts as well that are being created and rendered. It is us who has to take up the challenge to do those wonderful designs and tasks that we need. Moving on to the following topic of page and slug architecture we shall discuss in detail.
First let us look onto the following thing.
Creating Page Template for Custom Posts Type
Ex: If you are creating the post type called news the WordPress system will look for the following structures.
single-{post-type}.php
archive-{post-type}.php
single-{post_type}.php
If your custom post type were 'news', and/or query_var = "news", WordPress would look for single-news.php to display the single or permalink of the post.
archive-{post_type}.php
If your custom post type were 'news', and/or query_var = "news", WordPress would look for archive-news.php to display the archive of posts.
If these files are not available in your Theme's directory WordPress will look for archive.php and single.php, respectively. If even these files are not present it will default to index.php.
Template File will be like this.
<?php
$args = array( 'post_type' => 'news', 'posts_per_page' => 10,'post_status'=>'publish','orderby'=>'ID','order'=>'DESC' );
$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 wp_reset_postdata(); ?>
<?php else: ?>
<p><?php _e( 'Sorry, no posts matched your criteria.' ); ?></p>
<?php endif; ?>
Hence from the above code you can display the Latest Posts from News category in the count of 10.
If you need the count to be infinite you have to change the post_per_page=10 to post_per_page=-1.
Hope so this reference and advice that i have tried to explain will be helpful for you. Still if you face any issues about my explanation comment over to my answer and i am there to help you.
I didn't go this exact route to resolve my question as I am using the Advanced Custom Relationships plug-in. My solution is somewhat similar to this: https://www.advancedcustomfields.com/resources/querying-relationship-fields/ - but your response was very helpful and got me going on the right track, thank you!
I have a question, and i hope i am posting in the right place, if this topic belongs to another forum, please guide me where to post it.
the question is: i have a website created with WordPress and i am using the Jupiter theme, i need to hide some content (like hiding the last half of the article in a page) and disable the photos to be enlarged unless the visitor is a registered user, i need to know how to do that, and if there is a plugin to do that, i have tried "layered-popups-for-wordpress" and "optin-content-locker-layered-popups-addon" but they didn't work properly.
It might request a lot of effort for you to edit the theme on your own...You can use the_excerpt() insetead of the_content() for display info, and add a rule that only registered members can see, something like
if(is_user_logged_in()) {
the_content();
} else {
the_excerpt();
}
Do this while in the loop, of course...
These plugins might help you though
https://wordpress.org/plugins/tags/paid-content
If you're using WPMU might try this one
https://premium.wpmudev.org/project/pay-per-view/
I don't know of a plugin that does this automatically, but you can do it yourself if you are willing/able to do some minor theme development. Make a child theme of your Jupiter theme, and copy over the file content.php. There will probably be some part of the code that looks like this:
<?php if ( is_search() ) : ?>
<?php the_excerpt(); ?>
<?php else : ?>
...
Or something like that. The point is, the theme should already be set up to serve excerpted content for a search. You could either simply add code like this:
<?php if ( is_search() || !is_user_logged_in() ) : ?>
<?php the_excerpt(); ?>
<?php else : ?>
...
Or you could customize what non logged in users are seeing like this:
<?php if ( is_search() ) : ?>
<?php the_excerpt(); ?>
<?php else if (!is_user_logged_in()) : ?>
<!-- Your custom code display here -->
<?php endif; ?>
Hope that's helpful!
In order to hide certain parts of your content with just a simple shortcode you may give "Restrict Anonymous Access" plugin a try:
https://wordpress.org/plugins/restrict-anonymous-access/
Examples:
[member]My restricted content …[/member]
This shortcode can be placed wherever you need to hide something from logged-out users or even users of a certain user role can be addressed:
[member role="author"]My restricted content to users below author role …[/member]
I have one specific template which drupal_set_message() does nothing on. The $messages are printed out in a header include which also exists on this template. I've triple checked that it's using the template I think it is, etc.
The only difference I can tell between this and any other page template I'm using is that this is a node-specific template. Specifically page-node-170.tpl.php.
Anyone have any ideas?
Make sure that the custom template (page-node-170.tpl.php) has the following lines somewhere visible:
<?php if ($show_messages && $messages): print $messages; endif; ?>
<?php print $help; ?>
I'm trying to add two loops to a theme on two separate pages: home and blog.
Blog is basically an index of the posts. It's what most Wordpress pages default to as a home page. To accomplish this I went to "reading settings" and set "front page displays" as 'static' with "front page" set to a Home page I set up in Wordpress pages and "posts page" set to a Blog page.
Now the problem is that when I add the loop to the Home page, it doesn't work, presumably because I have posts page set to a different page.
So how do I get the loop to work on the Home page as well as the blog page? Btw, the Home page loop is just post title + date + maybe excerpts. Do I need to completely rework the theme or is this is just not a possibility under Wordpress?
Oh and the loop I'm using is:
<?php if(have_posts()) : ?>
<?php while(have_posts()) : the_post() ?>
There are at least three wayst to run custom queries in WordPress.
Query_posts() can define the query string of your second loop. It is easy and very common to do. This code is a basic structure I copied from the codex page for query_posts():
//The Query
query_posts('posts_per_page=5');
//The Loop
if ( have_posts() ) : while ( have_posts() ) : the_post();
..
endwhile; else:
..
endif;
//Reset Query
wp_reset_query();
You can also use get_posts() which is similar.
<ul>
<?php
global $post;
$myposts = get_posts('numberposts=5&offset=1&category=1');
foreach($myposts as $post) :
setup_postdata($post);
?>
<li><?php the_title(); ?></li>
<?php endforeach; ?>
</ul>
Both functions accept a number of arguments that are explained on the query_posts function reference page. The arguments shown above are only examples. The list of available args is long.
A third method available to you is to instantiate another instance of the WordPress Query object (WP's main query method). Query_posts and get_posts both run a second call to the database after WordPress runs the default wp_query. If you are super concerned about performance or reducing db hits, I suggest learning how you can interact with wp_query to modify the default query before it is run. The wp_query class provides a number of simple methods for you to modify the query.
Good Luck!
It is possible that WordPress does not start a loop for you because you use a static page. But if this static page is defined in your theme (since you include the PHP code to display the loop, I assume it is), you can always start a new loop there yourself. Just call query_posts yourself, and your code should start working.
