I have a custom post-type called reference. When I save a standard wp-post I would also like to save a copy of that post with the only difference is that it has post_type = 'reference';
I am using the following hook:
add_action('publish_post', 'create_reference', 10, 3);
function create_reference($id)
{
$post = get_post($id);
$ref = $post;
$ref->post_type = 'reference';
wp_insert_post($ref);
return $post // Seems that I need this line, otherwise the standard post wont save.
}
This seems to work but also changes the view in wp-admin which is confusing. Even though i am creating the post in the standard post view. The view changes to the reference post-type view.
I do not understand why this is happening and how it can be avoided.
Thank you.

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 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 $permalink;
}
add_action('init', 'add_rewrite_rules');
add_filter('post_type_link', 'permalinks', 10, 3);
put this code in your custom post type plugin. and if get page not found error please change your permalink setting. or make a custom template file to show this post.
I'm trying to run a do_shortcode in functions.php with no luck
I'm using Types plugin http://wp-types.com/ for creating custom post types and custom fields.
What I'm trying do is adding a custom column in admin for view all custom posts that displays a thumbnail from a custom field.
This is what I got so far, but it seems that the shortcode doesn't work inside functions.php
// add a column for custom post type (products)
add_filter('manage_product_posts_columns', 'add_thumbnail_column');
add_action('manage_product_posts_custom_column', 'add_thumbnail_content', 10, 2);
function add_thumbnail_column($defaults)
{
$newSlice = array('thumbnail' => 'Image preview');
$counter = 2;
$array_head = array_slice($defaults,0,$counter);
$array_tail = array_slice($defaults,$counter);
$defaults = array_merge($array_head, $newSlice);
$defaults = array_merge($defaults, $array_tail);
return $defaults;
}
function add_thumbnail_content($column_name, $post_ID)
{
// this one works when putting into post content
echo do_shortcode('[types field="square-picture" id="' . $post_ID . '" size="thumbnail"]' . '[/types]');
}
Can anyone help please?
In the Wordpress notes for the function it says
"If there are no shortcode tags defined, then the content will be
returned without any filtering. This might cause issues if a plugin is
disabled as its shortcode will still show up in the post or content."
Types may be conditionally declaring their short code only when you are on the frontend. What may be happening is that, in the admin, the short code is not defined and you are simply getting a false return. While on the frontend, the shortcode is defined and you get the results you intended.
I am using the save_post action to inspect a metadata field in a custom post and take some action on that value. This is the essential guts of how I am doing it:
add_action('save_post', 'my_save_post');
function my_save_post($post_id)
{
// Check if not autosaving, processing correct post type etc.
// ...
// Get the custom field value.
$my_field_value = get_post_meta($post_id, 'my_field', true);
// Do some action
// ...
}
This works fine when updating the post through the admin page. However, when first creating the post, the my_field_value is always empty. The field does get saved correctly, but this action trigger does not seem to be able to see it, nor any other custom field values.
I would like the action to be performed on all posts of this type created, and I will be importing many through the CSV Imported plugin. Even then, the custom fields do get imported correctly, and the action trigger does get fired for each row imported, but the save_post action still cannot see the custom field value.
So far as I can see from documentation, the post has already been created by the time this action fires, so I should always be able to see that custom metafield.
The answer, it seems, is in the order in which things happen. When creating a post from a form, the custom fields are all collected by the appropriate actions and added to the post before my save_post action fires. This means my trigger is able to see those custom field values.
When importing from CSV, the basic post is created first, and then the custom metafields are added. The save_post trigger fires on the first creation, before the metafields are added, and so the custom field data is not visible to the save_post action.
My solution was to catch the updates of the metadata using the updated_post_meta and added_post_meta actions as well as the save_post action:
add_action('updated_post_meta', 'my_updated_post_meta', 10, 4);
add_action('added_post_meta', 'my_updated_post_meta', 10, 4);
function my_updated_post_meta($meta_id, $post_id, $meta_key, $meta_value)
{
// Make sure we are handling just the meta field we are interested in.
if ($meta_key != 'my_custom_field') return;
if (wp_is_post_revision($post_id)) return;
if (get_post_type($post_id) != 'my_post_type') return;
if (trim($meta_value) == '') return;
// Do my custom task (linking this post to a parent post in a different
// post type). This is the same task performed by the save_post action.
my_link_product_track($post_id, trim($meta_value));
}
That is essentially what I do, and it seems to work well. I do encapsulate all the above into a custom class in the theme, and don't recommend using global scope variables as shown here, but this is just to show the method.
You should look at using $post->ID instead of $post_id -
$my_field_value = get_post_meta($post->ID, 'my_field', true);
get_post_meta in the Codex
EDIT:
Could you do something like this?
if($post->ID == ''){
$pid = $post_id;
} else {
$pid = $post->ID;
}
//$pid = $post->ID or $post_id, whichever contains a value
$my_field_value = get_post_meta($pid, 'my_field', true);
something that looks for a value in $post->ID and $post_id, and uses whichever one isn't blank?
is there a way (plugin) to insert html/css/images ect.. automatically into every wordpress post? most of my posts are going to be very similar so is there a plugin that will automatically insert the pre written html/css/ ect in every post as opposed to me entering it manually every time.
Thank you in advance ;-)
You can write your own simple function for this, see my example below:
add_filter( 'default_content', 'my_editor_content' );
function my_editor_content( $content ) {
global $post_type;
if( $post_type == 'post') { /* Or your custom post type, pages etc. */
$content = 'Your custom HTML/CSS content here';
}
return $content;
}
Place this in functions.php and it will be the default content of every new post/page/custom post type you create.
For a list of available post types, please refer to the Codex
You could use a plugin such as Ad injection, it will allow you to do what you need without having to alter / amend / ad any code to the templates or files
