Prism – getting plugins working

Hiding tags from meta data on post page

https://designwithvalerie.com/hide-specific-post-tag-wordpress/

One of the things that drives me nuts about WordPress’ taxonomy (tag) system is that you have no way to prevent your readers from viewing all of the tags you used on a post. Sometimes I just want particular tags to go away because I’m using them for internal purposes (either for quick internal links or for logic based functionality my themes are using for display purposes.) For example, if you wanted to display an affiliate disclaimer message only on posts with a specific tag but don’t necessarily want to show that entire tag to the reader in the post meta information.

So how do you hide a specific tag from a post? Well, you can install yet another plugin… but I personally don’t like to install new plugins when I can avoid it. Here’s how you can stop displaying specific tags on posts in WordPress without a plugin. It’s as simple as adding a few extra lines to your functions.php and a single line to your template file!

Keep a Specific Tag from Displaying on a WordPress Post

---

Step 1:
Make a backup of your theme’s functions.php and your single.php (or other template file) where you will use this function. Always make a backup before you begin!

Step 2:
Open your functions.php in a code or text editor, scroll to the bottom, and paste the following code:

 

//* Hide Specific Tags from the Post
//* ---------------------------------------------------------------------------
function show_tags_except_hidden() {

  $hide_tags = array( 'tag-slug-to-hide' );
  $tag_open_wrapper = '<div class="entry-tags">';
  $tag_close_wrapper = '</div>';
  $tag_title_before_name = "More Posts with the '";
  $tag_title_after_name = "' Tag";
  $separator = ' ';

  // Do not edit below this line
  // ---------------------------------
  $tags = get_the_tags( $post->ID );
  $output = '';
  $display_result = $tag_open_wrapper;
  if( $tags ) {
    foreach( $tags as $tag ) {
      $should_display_tag = true;
      foreach( $hide_tags as $hide_tag ) {
        if( $tag->slug == $hide_tag ) { $should_display_tag = false; }
      }
      if ( $should_display_tag === true ) {
        $output .= '<a href="'.get_tag_link( $tag->term_id ).'" title="'.esc_attr( sprintf( __( '%s%s%s', 'theme' ), $tag_title_before_name, $tag->name, $tag_title_after_name ) ) . '">'.$tag->name.'</a>'.$separator;
      }
    }
    $display_result .= trim($output, $separator);
  }
  $display_result .= $tag_close_wrapper;
  return $display_result;
}
//* ---------------------------------------------------------------------------

Step 3:
Modify the values of the $hide_tags array to include all the tag slugs that you want to be hidden when this list is displayed. This is the only value you really need to change.

If you want to modify the other variables in this section to match your theme and/or coding style, here is a detailed list of what each variable is and what it does.

• $hide_tags – A comma-separated array of the slugs for each tag you want to hide.
• $tag_open_wrapper – The opening container element that wraps all of the tag links.
• $tag_close_wrapper – The closing container element that wraps all of the tag links.
• $tag_title_before_name – The text to display in the link title before the tag name.
• $tag_title_after_name – The text to display in the link title after the tag name.
• $separator – Anything you want to show up between tag links.

Step 4:
Open your single.php in a code or text editor. In your code, find wherever you want to display your tag cloud (typically within a post meta section), and paste in the following code. This is display the results of the function we added in Step 2.

 

<?php echo show_tags_except_hidden(); ?>

 

Step 4:
Upload your modified functions.php and your single.php (or other template file) and test!

An Example of Hiding a Specific Tag

So for example, let’s say if you had a post that was tagged with tag0, tag1, and tag2. When you modify the function so the array in variable $hide_tags includes the slug for tag1, the displayed result will be HTML code that looks something like this:

 

<div class="entry-tags">
	   <a href="http://yourdomain/tag/tag0/" title="More Posts with the 'tag0' Tag">tag0</a>
	   <a href="http://yourdomain/tag/tag2/" title="More Posts with the 'tag2' Tag">tag2</a>
	</div>

 

 

Hiding from WP Search

https://www.vpsbasics.com/cms/how-to-exclude-pages-posts-authors-category-tags-in-wordpress/

Exclude Specific Pages From WordPress Search

To exclude specific pages from WordPress search simply copy and paste the following code into your functions.php file:

//Exclude Certain Pages from WordPress Search 

**function** vpsb_search_filter( **$query** ) {

  **if** ( ! **$query->is_admin** && **$query->is_search** && **$query->is_main_query**() ) {

​    **$query->set**( 'post__not_in', **array**( 10,11,20,105 ) );

  }

}

add_action( 'pre_get_posts', 'vpsb_search_filter' );

 

NOTE

Don’t forget to replace the ‘post__not_in’, array( 10,11,20,105 ) with the page ID you wish to exclude, for example, if the page IDs were 5, 10, 15, you would change the code to $query->set( ‘post__not_in’, array( 5,10,15 ) ); .

Exclude All Pages From WordPress Search

To exclude all pages from WordPress search simply copy and paste the following code into your functions.php file:

//Exclude All Pages from WordPress Search

**if** (!is_admin()) {

**function** vpsb_search_filter(**$query**) {

**if** (**$query->is_search**) {

**$query->set**('post_type', 'post');

}

**return** **$query**;

}

add_filter('pre_get_posts','vpsb_search_filter');

}

 

Now when a search term is entered into WordPress, the search will display the results for posts only and will exclude all pages from being displayed.

Exclude All Posts From WordPress Search

To exclude all pages from WordPress search simply copy and paste the following code into your functions.php file:

/Exclude All Posts from WordPress Search

**if** (!is_admin()) {

**function** vpsb_search_filter(**$query**) {

**if** (**$query->is_search**) {

**$query->set**('post_type', 'page');

}

**return** **$query**;

}

add_filter('pre_get_posts','vpsb_search_filter');

}

Now when a search term is entered into WordPress, the search will display the results for pages only and will exclude all posts from being displayed.

Exclude All Except Specific Custom Post Types From WordPress Search

To exclude all post types and only show specific custom post types in your WordPress search simply copy and paste the following code into your functions.php file:

// Exclude All Except Specific Custom Post Types From WordPress Search

**function** vpsb_search_filter( **$query** ) {

​    **if** ( !**$query->is_admin** && **$query->is_search** && **$query->is_main_query**() ) {

​        **$query->set**( 'post_type', **array**( 'post', 'recipe', 'cuisine', 'product' ) );

​    }

}

add_action( 'pre_get_posts', 'vpsb_search_filter' );

NOTE

Don’t forget to replace the ‘post_type’, array( ‘post’, ‘recipe’, ‘cuisine’, ‘product’ with the custom post types you wish to include, for example, if the custom post types were was media, photo, video, you would change the code to $query->set( ‘post_type’, array( ‘media’, ‘photo’, ‘video’ ) );.

Exclude Single Author From WordPress Search

To exclude a single author from WordPress search simply copy and paste the following code into your functions.php file:

//Exclude Single Author from WordPress Search

**function** vpsb_search_filter( **$query** ) {

​    **if** ( **$query->is_search** && !is_admin() )

​        **$query->set**( 'author','-12' );

​    **return** **$query**;

}

add_filter( 'pre_get_posts', 'vpsb_search_filter' );

 

NOTE

Don’t forget to replace the ‘author’,’-12′ with the author number you wish to exclude, for example, if the author number was 5, you would change the code to $query->set( ‘author’,’-5′ );.

Exclude Multiple Authors From WordPress Search

To exclude a multiple authors from WordPress search simply copy and paste the following code into your functions.php file:

//Exclude Multiple Authors from WordPress Search

**function** vpsb_search_filter( **$query** ) {

​    **if** ( **$query->is_search** && !is_admin() )

​        **$query->set**( 'author','-12, -22, -26' );

​    **return** **$query**;

}

add_filter( 'pre_get_posts', 'vpsb_search_filter' );

 

NOTE

Don’t forget to replace the ‘author’,’-12, -22, -26′ with the author numbers you wish to exclude, for example, if the author numbers were 5, 10, 15, you would change the code to $query->set( ‘author’,’-5, -10, -15′ );.

Exclude Single Category From WordPress Search

To exclude a single category ID from WordPress search simply copy and paste the following code into your functions.php file:

//Exclude Single Category ID from WordPress Search

**function** vpsb_search_filter( **$query** ) {

​        **$query->set**( 'cat','-7, -10, -21' );

​    **return** **$query**;

}

add_filter( 'pre_get_posts', 'vpsb_search_filter' );

 

NOTE

Don’t forget to replace the ‘cat’,’-7, -10, -21′ with the category IDs you wish to exclude, for example, if the category IDs were 5, 10, 15, you would change the code to $query->set( ‘cat’,’-5, -10, -15′ );.

//Exclude Multiple Tag IDs from WordPress Search

**if** ( **$query->is_search** && !is_admin() )

​        **$query->set**( 'tag','-15, -22, -44' );

​    **return** **$query**;

Exclude Custom Taxonomy From WordPress Search

To exclude a term in a custom taxonomy from WordPress search simply copy and paste the following code into your functions.php file:

//Exclude Custom Taxonomy from WordPress Search

**function** vpsb_modify_search_query( **$query** ) {

​    **global** **$wp_the_query**;

​    **if**( **$query** === **$wp_the_query** && **$query->is_search**() ) {

​        **$tax_query** = **array**(

​            **array**(

​                'taxonomy' => 'term',

​                'field' => 'slug',

​                'terms' => 'action',

​                'operator' => 'NOT IN',

​            )

​        );

​        **$query->set**( 'tax_query', **$tax_query** );

​    }

}

add_action( 'pre_get_posts', 'vpsb_modify_search_query' );

 

NOTE

Don’t forget to replace the custom taxonomy term ‘taxonomy’ => ‘term’,
with term you wish to exclude, for example, if the term was birds, you would change the code to ‘taxonomy’ => ‘birds’, .

You can change the code array to anything you like. The taxonomy array is the custom taxonomy. The terms array is the taxonomy category to exclude. With the taxonomy category you can also exclude multiple taxonomy categories by changing the array to ‘terms’ => ‘action’,’adventure’,’movie’. The operator array will show posts that aren’t part of the action category. If you want to show posts that are only in the action category you would change the code from NOT IN to IN.

That’s it. You have now successfully updated your functions.php file to exclude Pages, Posts, Authors, Categories or Tags from being displayed in your WordPress search results.
