In my wordpress cms, I display a regular list of all existing tags on my single template. Now I need to exclude one specific tag and show it only to the logged in people. What wordpress function/hook should I be looking into ?
EFFORTS - I know that I could use is_user_logged_in() and am also looking into is_tag() but how do I put this together. Currently I am having it displayed on my single template with the_tags() but it does not seem to offer such parameter to exclude a particular tag.
Psuedo code would be : If user is logged in show all tags except this specific tag.
add_filter('get_the_terms', 'tag_filter', 100, 1);
function tag_filter($tags) {
$exclude = array('hello', 'demo', 'tag_one', 'tag_two');
foreach($tags AS $index => $tag) {
$name = $tag->name;
#$name = $tag->slug;
if(in_array(strtolower($name), $exclude)) {
unset($tags[$index]);
}
}
return $tags;
}

I want to be able to hide certain Wordpress Post Categories from Users dependent on their Role.
I've tried the code here:
Wordpress: Hide specific categories from User Role on the Add New page
I think its deprecated, and would really appreciate some help
add_filter('list_terms_exclusions', 'yoursite_list_terms_exclusions', 10, 2);
function yoursite_list_terms_exclusions( $exclusions, $args ) {
global $pagenow;
if (in_array($pagenow,array('post.php','post-new.php')) && !current_user_can('see_special_cats')) {
$exclusions = " {$exclusions} AND t.slug NOT IN ('slug-one','slug-two')";
}
return $exclusions;
}
With this code nothing happens. I've tried 10+ different plugins and am really getting desperate. Thanks in advance.
add_filter('list_terms_exclusions', 'yoursite_list_terms_exclusions', 10, 2);
function yoursite_list_terms_exclusions( $exclusions, $args ) {
global $pagenow;
if (in_array($pagenow,array('post.php','post-new.php')) &&
!current_user_can('see_special_cats')) {
$exclusions = " {$exclusions} AND t.slug NOT IN ('slug-one','slug-two')";
}
return $exclusions;
}
This code presumes that you've used a plugin like the Members plugin to create a capability called 'see_special_cats' and that you've assigned it to every role that you want to have access to the categories except of course 'Contributors'.
Since you found the plugin you may not need this, but maybe it will help someone else.
add_filter('list_terms_exclusions', 'yoursite_list_terms_exclusions', 10, 2);
function yoursite_list_terms_exclusions( $exclusions, $args ) {
$current_user = wp_get_current_user();
// Change 'see_special_cats' to capability user must have to be able see category or categories
if ( $current_user->has_cap('see_special_cats') ) {
$capCheck = 1;
} else {
$capCheck = 0;
}
global $pagenow;
if (in_array($pagenow,array('post.php','post-new.php')) && !$capCheck) {
// Change category-slug-one and two to desired categories to hide. Additional categories may be added
// by separating with a comma. Delete ", 'category-slug-two'" to only hide one category
$exclusions = " {$exclusions} AND t.slug NOT IN ('category-slug-one', 'category-slug-two')";
}
return $exclusions;
}
This code works without using current_user_can(). Paste this code in your functions.php file. If you want to hide a category from everyone except for the Administrator role, as set up by the default hierarchical structure, change 'see_special_cats' to 'create_users'. Change category-slug-one and category-slug-two to the category slugs that you want hidden. There is no additional plugin required (I'm not sure where 'see_special_cats' comes from).
Good Day,
I have been trying to add verification badge to WordPress users but I no success. I tried using administrator to do the testing by checking if user has role administrator and trying to enter code here update_user_meta (display_name) but I wasn't able to add icons to the display name.
I have as well tried creating a custom field in user profile called verify_user (text field) .... In which I entered the value "verified" and saved ... I have been searching for hooks to use but haven't seen one. I'm not sure which hook/filter to use here
Please is there any solution to adding this verification icon to author's display name in which when the word "verified" is entered into the custom field created in user profile or any other approach available (e.g if user has specific role). I don't mind if the little structure I wrote above would be changed.
Thanks
I was able to get a solution which worked exactly as i wanted. For anyone who might have same task to tackle;
function add_verification_bagdge_to_authors($display_name) {
global $authordata;
if (!is_object($authordata))
return $display_name;
$icon_roles = array(
'administrator',
'verified_author',
);
$found_role = false;
foreach ($authordata->roles as $role) {
if (in_array(strtolower($role), $icon_roles)) {
$found_role = true;
break;
}
}
if (!$found_role)
return $display_name;
$result = sprintf('%s <i title="%s" class="fa fa-check-circle"></i>',
$display_name,
__('This is a Verified Author', 'text-domain-here')
);
return $result;
}
add_filter( 'the_author', 'add_verification_bagdge_to_authors' );
The way i was able to tackle this was to create a user role called Verified Author (using add_role() function from Wordpress Codex ), which will be the role assigned to verified author across the website. All Users with Admin Role are automatically Verified while user role has to be switched from either contributor/Author role to Verified Author.
The above code was able to do 98% of the task but when a verified author / administrator comments, their display name doesn't show the verified badge. I was able to use the below code to fix that (combining the code with a shortcode).
function my_comment_author( $author = '' ) {
// Get the comment ID from WP_Query
$comment = get_comment( $comment_ID );
if ( ! empty($comment->comment_author) ) {
if (!empty($comment->user_id)){
$user=get_userdata($comment->user_id);
$author=$user->display_name.' '. do_shortcode('[this_is_verified-sc]'); // This is where i used the shortcode
} else {
$author = $comment->comment_author;
}
} else {
$author = $comment->comment_author;
}
return $author;
}
add_filter('get_comment_author', 'my_comment_author', 10, 1);
Shortcode to return the Verified Badge if user is admin or verified author
function add_verification_bagdge_to_authors_sc($display_name) {
global $authordata;
if (!is_object($authordata))
return $display_name;
$icon_roles = array(
'administrator',
'verified_author',
);
$found_role = false;
foreach ($authordata->roles as $role) {
if (in_array(strtolower($role), $icon_roles)) {
$found_role = true;
break;
}
}
if (!$found_role)
return $display_name;
$result = sprintf('%s <i title="%s" class="fa fa-check-circle"></i>', $display_name, __('This is a Verified Author', 'text-domain-here') );
return $result;
}
add_shortcode( 'this_is_verified-sc', 'add_verification_bagdge_to_authors_sc' );
Please Note: Not all Magazine theme are properly coded / have a hard coded Block and module elements, so the verified badge might not work on their block / module element. I experienced this during the whole website design process, so we had to change up theme and the only modification i had to make to the new theme was to remove the html escape added to their block/module code, so that the icon can be rendered. i.e. in their module/block code they had something like this esc_html( the_author() ) and i removed the esc_html to have just the_author() an it all worked.
Its not really a straight forward solution but that is how i was able to tackle the task without using a plugin. Just add the codes to your functions.php file and that's it. I hope it helps someone.
Thanks to Kero for pointing me in the right direction, providing the code i was able to work with and manipulate
Check the screenshot below; all I want to do is to hide certain ACF fields for custom users in the wordpress backend.
As of ACF 5.0.0 there is an easier way to do this without having to output CSS. If you use the acf/prepare_field hook and return false the field will not render.
<?php
function so37111468_hide_field( $field ) {
// hide the field if the current user is not able to save options within the admin
if ( ! current_user_can( 'manage_options' ) ) {
return false;
}
return $field;
}
add_filter( 'acf/prepare_field/key=MYFIELDKEY', 'so37111468_hide_field' );
?>
The documentation for that filter can be found here: https://www.advancedcustomfields.com/resources/acf-prepare_field/
If you mean to hide it with CSS, then you should insert custom CSS to admin footer area.
For example, you can add such kind of code to your theme's functions.php file:
add_action('admin_footer', 'my_admin_hide_cf');
function my_admin_hide_cf() {
$u=wp_get_current_user();
$user_roles = $u->roles;
if ($user_roles[0]=='CUSTOM_USER_ROLE_NAME'){
echo '
<style>
#acf-FIELD_SLUG_HERE {display:none}
</style>';
}
}
And of course you should replace FIELD_SLUG_HERE and CUSTOM_USER_ROLE_NAME values with correct ones.
F.e. #acf-FIELD_SLUG_HERE can be #acf-url, CUSTOM_USER_ROLE_NAME can be "contributor".
Maybe someone are able to help me. I want to change product attribute URL from pa_ to something else. (for example http://website.com/?pa_color=black to ?product_color=black.)
Any solution guys?
Best Regards
The functionality that allows you to use a custom base in your url instead of the pa_ in your product attribute are no longer standard with WooCommerce.
You will have to first make sure that you have set your taxonomy permalinks to the bases you would like the product urls to have. If you go into WordPress Dashboard > Settings > Permalink menu you can change the categories, terms and attributes to whatever makes the most sense for your product. By changing these preferences you can use a custom base on your products (be sure not to repeat bases within the taxonomy, this will create a conflict).
You will then need to add the following code to your theme's functions.php file:
// Change attribute rewrite rules
add_action('woocommerce_register_taxonomy', 'razorfrog_woo_register_taxonomy');
function razorfrog_woo_register_taxonomy() {
global $razorfrog_woo_attribute_labels;
$razorfrog_woo_attributes_labels = array();
if ( $attribute_taxonomies = wc_get_attribute_taxonomies() ) {
foreach ( $attribute_taxonomies as $tax ) {
if ( $name = wc_attribute_taxonomy_name( $tax->attribute_name ) ) {
$razorfrog_woo_attribute_labels[ $tax->attribute_label ] = $tax->attribute_name;
add_filter('woocommerce_taxonomy_args_'.$name, 'razorfrog_woo_taxonomy_args');
}
}
}
}
function razorfrog_woo_taxonomy_args($taxonomy_data) {
global $razorfrog_woo_attribute_labels;
if (isset($taxonomy_data['rewrite']) && is_array($taxonomy_data['rewrite']) && empty($taxonomy_data['rewrite']['slug'])) {
$taxonomy_data['rewrite']['slug'] = $razorfrog_woo_attribute_labels[ $taxonomy_data['labels']['name'] ];
}
return $taxonomy_data;
}
Hope this helps!
I have an external page that reads a RSS feed for a tag. I can't change anything on the external page, so the challenge is to change the RSS feed on my side to match the requirements.
On the external page the 3 latest posts for a tag are shown, and at the end of the section (note: not after each post but after all 3 posts) there is a "View all" link. This link receives its value from the element in the feed, which is by default set to my blog homepage, e.g. http://myblog.com). For this specific tag the link should be http://myblog.com/tag/myspecialtag.
The requirement is that the "View all" link links to the tag page instead of the homepage.
My idea was to add a condition to the element to change the URL for this specific category. I tried to change the feed template as recommended here: Customizing feeds, but for some reason it doesn't change the template at all. The code I tried is the following:
remove_all_actions( 'do_feed_rss2' );
add_action( 'do_feed_rss2', 'change_feed_rss2', 10, 1 );
function change_feed_rss2( $for_comments ) {
$rss_template = get_template_directory() . '/feeds/feed-custom_rss2.php';
if( file_exists( $rss_template ) )
load_template( $rss_template );
else
do_feed_rss2( $for_comments ); // Call default function
}
Of course I created the custom feed template and stored it in the feeds directory in my theme.
As this didn't work I tried looking into filters/hooks but I couldn't find anything helpful regarding my issue. Any ideas on how to best solve this issue?
I came up with the following solution:
I created a new custom page template custom_rss-feed.php and copied the code from wp-includes/feed-rss.php into it. I assigned this template to a new page. Additionally I added a filter to get_bloginfo_rss like the following:
function alter_bloginfo_rss($value, $key) {
if ( $key === "url" &&
is_page_template("custom_rss-feed.php")
) {
return $value . "/my/custom/url";
}
return $value;
}
add_filter("get_bloginfo_rss", "alter_bloginfo_rss", 10, 2);
