I've been looking for a way to automatically append a category everytime a post is set to private. I've seen several of ways of doing this for custom post types but i've yet to figure out a way how to achieve this with post visibility.
Any ideas?
This filter should do the job.
function add_categories_automatically($postID) {
if(get_post_status($postID) == 'private'){
$catsID = array(5);
wp_set_post_categories($postID, $catsID, true);
}
}
add_action('publish_post', 'add_categories_automatically');
This will check the post status when it is published. If the status is private, specified categories will be appended to the post.
Be careful, as wp_set_post_categories will overwrite any existing categories already assigned to the post unless the third parameter is set to true: wp_set_post_categories

I have been trying to associate CUSTOM data to each of my WP POSTS using the following piece of code :
if($condition === true){
if ( ! update_post_meta ($post_id, '_someData', $someVariable) ) {
add_post_meta($post_id, '_someData', $someVariable);
}
}
However, seems like the META VALUE is RESET to default i.e. Zero OR Blank. Our WordPress website has around 40 plugins, and I think one of these WordPress plugins, is coming in my way of doing things. All of my logic works fine, on a demo WordPres website. Is there a way for me to have total control to set the META Value for a given POST ? Also, is there a way where I can be notified that the META Key is about to change and then I can decide whether OR not to change the Meta Value ?
Any pointers or reference URL's can be of great help. Thanks !
You only need to call update_post_meta in either scenario. Calling add_post_meta() is not necessary and could be causing this problem.
From the codex:
The function update_post_meta() updates the value of an existing meta key (custom field) for the specified post.
This may be used in place of add_post_meta() function. The first thing this function will do is make sure that $meta_key already exists on $post_id. If it does not, add_post_meta($post_id, $meta_key, $meta_value) is called instead and its result is returned.
I have a wiki built with drupal, with a taxonomy category Workgroup, assigned to both the users and the articles. I am using apache solr search module with facet api and my end goal is to set up the search so that by default when users search for the articles, only articles from their workgroup are shown.
That is, when they launch the search from a search box, they should get the same results as for /search/site/hello?f[0]=im_field_kb_workgroups%3A4529 (where 4529 is one workgroup id) instead of just /search/site/hello (current behavior) Users should still be allowed to search in other workgroup facets when they want, by removing the checkbox in the facet block.
I have this working almost by hacking the apachesolr module (not recommended I know but really want this to work). In the function apachesolr_search_custom_page_search_form_submit, I have:
// Get the workgroup id
global $user;
$account = user_load($user->uid);
$user_kb_wg_fieldinfo = field_get_items('user', $account, 'field_kb_workgroups');
$user_kb_wg_tid= '';
if ($user_kb_wg_fieldinfo) {
$user_kb_wg_tid = $user_kb_wg_fieldinfo[0]['tid'];
}
// Add the solr filter for this workgroup facet so that by default, search results are
// fetched only from that workgroup.
if ($user_kb_wg_tid === '4529') {
$get['f[0]'] = 'im_field_kb_workgroups:4529';
}
This does the job but the problem is that this relies on the apachesolr search form. I have users coming to the wiki by searching from sites external to the wiki, where the wiki search form is just a simple POST form pointing to the KB domain and the path /search. So this will work only when people are searching from inside the wiki, where I present them the apachesolr search form.
I have investigated some other options:
In my custom module, I implement this hook (without the user workgroup checks for now, for testing):
function kb_hacks_apachesolr_query_prepare($query) {
$query->addFilter('im_field_kb_workgroups', '4529');
}
This filters the results from searches everywhere, but the filter is applied all the time, and users don't get to deselect this or other filters. (in fact, other filters appear only when passing the filter as a GET param like above with f[0])
I also played with the url_inbound_alter hook, but could not figure out how to pass the solr query param as GET. The following did not work.
function kb_hacks_url_inbound_alter(&$path, $original_path, $path_language) {
if ($path == 'search/site/hello') {
$_GET['f[0]'] = "im_field_kb_workgroups:4529";
//$_GET['f[0]'] = "im_field_kb_workgroups%3A4529";
//$path = 'search/site/hello?f[0]=im_field_kb_workgroups%3A4529;
}
}
Is there a way to set GET params from this hook? But even if this had worked, I would still have to figure out how to do this only by default (when the search form is submitted), and not when the filter itself is deselected. Is there a way to detect checkbox changes in the facet block?
Maybe there's another way to do this? I have been stuck here for the last two days and would really appreciate any help I can get. Thanks!
You can add a relationship to the taxonomy term "Workgroup" and use a contextual filter for the current user. In the contextual filters section, you can change the behavior when the filter is not present.
Hard to define the Title of this Question....
I want to create a nice readable permalink structure for my 2 custom post types (CPT).
My first CPT "family" has the following rewrite-slug "family/%postname%" (all works fine)
The second CPT "childs" has a metabox where I can select the parent_id-field by choosing a CPT "family" where the child-CPT belongs to. That also works great.
Now I set the rewrite-slug for "childs" to "%parent_post_url%/child/%postname%" so that I can get the following URL "family/the-griffons/child/peter" . But when I call this URL wordpress displays a not-found-page. The crazy thing is that if I set the rewrite-slug hard to "family/the-griffons/child/%postname%" I can call the URL (both URLs are the same!!!)
So why toes WP throws an error when I try to get the URL dynamically but not when I hardcode the URL??
The child-parent relationship you think you have is not quite there. Based on what you've told us so far, it seems that all you have is a custom field denoting the "pseudo-parent" id. So what your question should really read is
How do I rewrite the first part of the cpt url, based on the cpt custom field value ?
because, as far as wordpress is concerned in your case, that's all that "parent id" really is- a custom field value.
you can try following the last part(Part 3.) of this tutorial, keeping in mind, that you'll want the actual path of the url of the "parent id" and not the cf "parent id" value itself, you'll have to implement something along the lines of:
$parent_id = get_post_meta($post_id, "your_cf_key_for_parent_id", true);
$full_parent_post_url = parse_url( get_permalink( $parent_id ) );
$parent_post_url = $full_parent_post_url['path'];
if(!$parent_post_url) { $parent_post_url = "default-fallback" }
$permalink = str_replace(‘%parent_post_url%’, $parent_post_url, $permalink);
return $permalink;

BUT as #c0ns0l3 mentioned using custom taxonomies IS the proper way to go about this.
I'm trying to change the order of a particular archive (custom type/taxonomy) to order by title rather that chronological. I've looked in archive.php and loop.php. How do i pass parameters to the default loop?
Try using the posts_orderby_request filter. You can check to see if the request is for your custom type, then return a different ORDER BY string. Look in wp-includes/query.php on line 2583.
I would like to know the best method for layering posts in wordpress 3.0 when you need to swap back and forth between structure and data. For example, custom post type 1 has 6 custom fields, each field contains a value for the tab shortcode; i.e. [tab:data] [tab:credits] [tab:where to buy] etc - this type is standard every time the page is called and always the same post; then it needs to switch to another custom post type and select the data post it's going to use based on what tag page is being called. Then it needs to pump a custom field from data post into the same display space as the base structure post, and then hop back and forth between structure and data, and THEN run a loop. Thanks in advance.
I would just query for the two special posts before you do the loop, with get_posts (which will not mess up the regular query). Then you can display them however you want, with their information mixed together, and then do the loop.
In this example, $fixed_post is a fixed post with slug "fixed_post_slug" of the custom post type "fixed_posts". $tag_post is a post where the name equals the current tag (if we are showing a tag page), and of custom post type "tag_posts".
$fixed_post = get_posts(array('name' => 'fixed_post_slug', 'type' => 'fixed_posts'));
if ($fixed_post) {
$fixed_post = $fixed_post[0]
}
$tag_post = get_posts(array('name' => get_query_var('tag'), 'type' => 'tag_posts'));
if ($tag_post) {
$tag_post = $tag_post[0];
}
