been struggling finding a solution to my problem for weeks.
Case :
I have a custom post type named : design. This CPT have a custom field (made with ACF plugin) called thematique. I created the same custom field (thematique) for design's categories.
Expected behaviour:
I want that whenever if we make a get_posts() or WP_Query if a design's thematique field is empty, it should inherit its categorie's thematique.
I've investigated into the pre_get_posts hook but I'm not quite sure how to handle it.
Anybody has an idea ?
Thanks in advance, I really appreciate your help !
You can just do this the easy way and inside your WP Query where you have the formatting for each returned item add this:
<?php $thematique = get_field('thematique'); //Gets current posts value of fiels
<?php if (empty($thematique)){ //Checks if the field is empty, if so do the following
$postCat = get_the_category(); //Get current posts category ID
$catID = 'category_' . $postCat; //Merge category ID and needed string for ACF
$thematique = get_field('thematique', $catID); //Updated the value of $thematique with categories value
}?>
Although not tested this should indeed work as it's how ACF says to get the value from categories. Find out more here.

I'm not so sure about how to go about it though. I would need something like :
// Designs Thematique priority mechanic
function design_thematique_priority($query){
if($query->query['post_type'] == "design"){
foreach($query->posts as $post){
if($post->thematique == ""){
$post->thematique = $post->category->thematique;
}
}
}
}
add_filter( 'pre_get_posts', 'design_thematique_priority' );
But I don't think there is any loop I can use to loop through posts in pre_get_posts right ?

I have custom post types for which having a 'title' field doesn't really make sense, so the post type has none.
Problem is that when you use a post type in a relationship, the user interface for picking which posts to relate wants to display the title.
In the box where you are choosing posts (clicking them and they move to the right pane), can a field other that 'title' be displayed?
It's doable. I would use a filter hook provided by acf plugin 'acf/fields/relationship/result/name=related_posts'. Take a look at the following code:
add_filter( 'acf/fields/relationship/result/name=related_posts', 'my_custom_title', 10, 2 );
function my_custom_title( $title, $acf_array ) {
// You could remove the $title altogether or you could add something meaningful to it such as time stamp or anything that would make sense!
return $title . "Adding somthing meaningful to the title!";
}
So I'm trying to reference custom field values in a plugin I'm building. All I need to do at this stage is grab the values and store them in variables. This is my code to get the custom field value of pageName:
<?php
global $wp_query;
$postid = $wp_query->post->ID;
$pageName = get_post_meta($postid, 'pageName', true);
wp_reset_query()
?>
So when I try to echo that out, I get nothing. I notice that my plugin runs before the head or anything else, so it's the first code in the source. My hunch is that this is due to timing and the value just isn't there yet. Is there a way to make my plugin, or this chunk of code, wait until the custom field values are there before trying to grab them?
I'm trying to avoid doing anything in the theme files so this can be a stand alone plugin that I can share.
yes, you can get the value of any post meta of the custom post type.
Just make sure that you are receiving the correct post_id in the $postid variable.
If you get the correct id of the post type you can get any meta field
Example:
global $post;
if ($post->ID) {
$media_id_meta = get_post_meta($post->ID, 'media_id', true);
}
Found the solution! I wrapped the whole thing in a function to put it in the footer, which made sure that everything it needed was there.
//----This function is wrapped around the code for my plugin
function dataLayerInject() {
*ALL MY CODE*
}
//----This drops my code into the footer
add_action('wp_footer', 'dataLayerInject');
I have added a new column to a custom post type to display the post's ID. This works for the WordPress core post type, but not for my custom post type. I have tried using the manage_{post_type}_custom_column hook and just applying it to all posts, but neither works.
It DOES add the custom column headers, but I can't populate them with anything at all when viewing the custom post type.
This is what it looks like when viewing the custom post type
and
this is what it looks like when viewing a regular core post.
// Add post ID column to use an order ID in all posts view.
add_filter('manage_posts_columns', 'oms_order_id_header');
add_action('manage_posts_custom_column', 'oms_order_id_column', 10, 2);
function oms_order_id_header($columns) {
//Remove title column
//unset($columns['title']);
//Add new columns
$columns['order_id_header'] = 'Order ID';
$columns['customer_header'] = 'Customer';
$columns['author'] = 'Owner';
return $columns;
}
function oms_order_id_column( $column, $post_id ) {
if ($column == 'order_id_header') {
echo $post_id;
}
}
This turned out to be an issue with the post type being set to hierarchical. Hierarchical post types need to be targeted by a different action hook than the one used here.
Instead of manage_posts_custom_column, hierarchical post types need to use manage_pages_custom_column.
I just tried you code and it seems to be working perfect on my WordPress installation in both cases: Custom Post and Post.
Maybe your error is happening because your posts are drafts? I don't think so but maybe. (I tried your code also with drafts on my installation and it worked). Here is the screenshot:
Try printing "hello world" instead of the $post_id to check if it prints in all cases.
I have a WordPress installation with a custom type (places) wich produces this permalink structure:
http://example.com/places/the-first-site/
And I would like to show all my sites like this:
http://example.com/places/visit-the-first-site-and-enjoy/
where 'visit' and 'and-enjoy' would be always those specific words (constants).
Even better I would like to put a custom taxonomy I have (year) as a metadata
places/visit-the-first-site-and-enjoy-1985/
I can access the DB and modify the post name of all post, but I would have to do for the new post also, and I'm looking for some automated rule, but can't find how to do.
Maybe some rewrite rule, but I don't know how to do it.
Any ideas??
You do not have to edit anything in your database nor any codes in your WordPress installation; you can achieve that directly from your WordPress administration panel.
From your Dashboard, click on the Permalink sub-menu under Settings; there, you will have to select the Custom Structure option and set it as follow in order to achieve your desired effect:
/places/visit-%postname%-and-enjoy-%year%/
Please note: here, we made use of both %postname% and %year% Structure Tags so as to get names of posts with their corresponding year of publication respectively.
Don't forget to click on the Save Changes button on the page in order to effect your changes.
... Read more on Permaklinks (for general knowledge).
For a custom post type and taxonomies as expressed further in comments, you will need a custom solution which will require a little bit of coding and or tweaking, depending on your abilities; you may use this handy plugin (Custom Post Type Permalinks) from the WordPress.org Plugins repository.
This posts should equally be of great help to you, to getting started and understanding further, should you chose to code.
You have différent hook like save_post or pending_to_publish, where you can set or change the "post_name" (that's corresponds to the permalink slug).
To Add specific words to WordPress custom type slug You have to Register custom rewrite rules.
suppose this is Your URL http://example.com/places/the-first-site !
and you have a post type places.
function add_rewrite_rules()
{
$wp_rewrite->add_rewrite_tag('%places%', '([^/]+)', 'places=');
$wp_rewrite->add_rewrite_tag('%state%', '([^/]+)', 'state=');
$wp_rewrite->add_permastruct('places', 'places/visit-%state%-and-enjoy/', false);
}
function permalinks($permalink, $post, $leavename)
{
$no_data = 'no-data';
$post_id = $post->ID;
if($post->post_type != 'story' || empty($permalink) || in_array($post->post_status, array('draft', 'pending', 'auto-draft')))
return $permalink;
$state = get_post_meta($post_id, 'location', true);
if(!$state)
$state = $no_data;
$permalink = str_replace('%state%', $state, $permalink);
return $permalink;
}
add_action('init', 'add_rewrite_rules');
add_filter('post_type_link', 'permalinks', 10, 3);
put this code in your custom post type plugin. and if get page not found error please change your permalink setting. or make a custom template file to show this post.
I have a post type named 'Property'.
I want to show single post in two different way.
if anyone click on post then it will shows a simple layout with name of post and description.
Now i have also category for beds. now if anyone goes in category '2 Bed' then you can see all post with '2 Bed' categories('its done'). but now if anybody click on post then it have to show different single page.
my English is very bad so please excuse it.
You can set up individual templates for a single category by using the single_template hook.
Put this in your functions.php file:
function my_category_templates($single_template) {
global $post;
if ( in_category( 'property' )) {
$single_template = dirname( __FILE__ ) . '/single-property.php';
}
// Copy the above for your other categories
return $single_template;
}
add_filter( "single_template", "my_category_templates" );
You can then create individual single templates for each category, just add more conditions and point them to the template you create.
There is the concept of Category Templates as dictated by the
Template Hierarchy but because you are asking how to display a "single" post based on category, you will want to use the in_category() Conditional Tag in the Template file you use to display singe posts. The Loop article has an example of using in_category.
Or look at this concept:
http://www.nathanrice.net/blog/wordpress-single-post-templates/
Or this:
http://justintadlock.com/archives/2008/12/06/creating-single-post-templates-in-wordpress
Or this plugin:
http://wordpress.org/extend/plugins/custom-post-template/
Or this plugin:
http://guff.szub.net/2005/07/21/post-templates-by-category/
So according to the Wordpress template hierarchy there is only one single.php, that cannot be separated by category (like the archive page for example.)
https://developer.wordpress.org/themes/basics/template-hierarchy/
So in this case I suggest you read the current category id in your single.php file and then adjust the content to your needs. You can use get_the_category() do do this (reference: https://developer.wordpress.org/reference/functions/get_the_category/) which will return you an array with categories. In my simple example I just pick the first category to do something:
$categories = get_the_category();
$category_id = $categories[0]->cat_ID;
if($category_id == 1) echo 'do something here';
Thanks for you help. I am done with it myself.
I create single.php for simple format and and in category result i didn't use the_permalink and call id of post and made a url like http://localhost/demo/page?id=$id
