Ok, so I found this code, which I modified to suit my needs. Btw, I'm using WooCommerce, which explains the "wc" in some of the function calls:
//Add login/logout link to primary menu
add_filter( 'wp_nav_menu_items', 'add_loginout_link', 10, 2 );
function add_loginout_link( $items, $args ) {
if (is_user_logged_in() && $args->theme_location == 'primary') {
$items .= '<li>Log Out</li>';
}
elseif (!is_user_logged_in() && $args->theme_location == 'primary') {
$items .= '<li>Log In</li>';
}
return $items;
This adds the login/logout menu items, and they work fine. However, they're stuck at the end of the menu, at the moment. I'd like to be able to edit the position using the editor in wp-admin. The solution I thought of was to maybe just create login and logout pages, and use header location redirects with those lines of code in them to get to the proper URLs, but the issue I see with that is that there will always be a login item and logout, no matter what status the user is currently in. Would there maybe be a way to dynamically add a site-wide CSS rule to hide the opposite menu item, based on the log in status?
Or is there an easier way?
Not the best idea but you can try.
Create in wp-admin menu section new menu item like "Custom Link"
Log Out
http://www.example.com/account/customer-logout/
Log In
http://www.example.com/account/
And add a custom class to a WordPress menu item to manage visibility
For example, you will see "logged-in" class on the body of the page and hide "Log In" link or change it to "Account" with the same link.
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);
I'm not sure if this is possible or advisable, but I'd like to have a top-level menu item on the sidebar in the admin dashboard that links to a specific page within wordpress for editing.
Maybe there's a better way of doing this... here's the functionality I'm after:
I have a page called "Upgrade Contents" where my client can edit the contents of their upgrade package sitewide. I'd like them to be able to edit this page directly from the admin dashboard, like a setting page. Problem is, I don't know how to add a link to edit this page to the admin AND I already have everything set up with ACF using this page.
Is adding a link easy to do or should I just scrap it and make a settings page for my theme and add THAT to the admin?
To add a link at the top level of the menu you can add an item to the global $menu array, like this:
function link_to_user_settings() {
global $menu;
$title = 'User Settings';
$url = 'URL_OF_YOUR_PAGE';
$position = 73;
$permission = 'read';
$icon = 'dashicons-admin-links';
$menu[$position] = array( $title, $permission, $url, '', 'menu-top', '', $icon );
}
add_action( 'admin_menu', 'link_to_user_settings' );
Change the variables accordingly to your needs.
The $position var is where you want the link to appear based on the default positions you can find at the add_menu_page() documentation (in my example 73 means after the Users menu item).
I am looking for a wordpress plugin that will allow me to add a paragraph to the sidebar that is specific to the blog post. I would need to be able to add that text when creating the post. Is there something out there like that? I have been unsuccessful in searches.
Thanks
This can be easily solved using Custom Fields, the Text Widget and a Shortcode.
This bit of code goes in the theme's functions.php or, preferable, within a custom plugin.
1) Enable shortcodes for the Text Widget
add_filter( 'widget_text', 'do_shortcode' );
2) Define the shortcode, read comments for details
add_shortcode( 'mytext', 'so_13735174_custom_text_widget' );
function so_13735174_custom_text_widget( $atts, $content = null )
{
global $post;
// $post contains lots of info
// Using $post->ID many more can be retrieved
// Here, we are getting the Custom Field named "text"
$html = get_post_meta( $post->ID, 'text', true );
// Custom Field not set or empty, print nothing
if( !isset( $html ) || '' == $html )
return '';
// Print Custom Field
return $html;
}
3) Add a Text Widget in the desired sidebar.
Leave the title empty and put the Shortcode in the content: [mytext].
4) Now each page or post with a Custom Field named text will have its value printed in the Widget.
5) The $html can get fancy and multiple Custom Fields can be used.
This isn't something that I've ever personally done, but try this.
Summary: You will add the a paragraph using a custom field, then display it in a widget.
Details:
First, make sure custom fields are enabled. Edit a post, then click
the "screen options" at the top right of the page. If "Custom
Fields" isn't checked, check it. You should now see a custom field
area below the post editor.
Come up with a name for your custom field. Perhaps
"extra_paragraph". Now put that in the "name" field in the custom
field area.
Write your paragraph in the "value" field the custom field area.
Install the Custom Field Widget plugin, set it to display this
new "extra_paragraph" field. (widget appears to be untested with newer versions of Wordpress so cross your fingers!)
Now when you write or edit posts you should see this "extra_paragraph" field as an option in the "name" dropdown.
I'm building a WordPress plugin and I'd like to have an edit-item page that can't be reached via the submenu (because then the item wouldn't be specified).
This resource (http://codex.wordpress.org/Adding_Administration_Menus) shows how to associate an admin page with a function, but not how to do so without adding it as a menu item.
Can this be done?
Thanks!
Best solution here http://wordpress.org/support/topic/add-backend-page-without-menu-item
use add_submenu_page with parent slug = null
I have finally discovered a way to do this that isn't an ugly hack, doesn't require JS to highlight the desired menu item (and submenu item), and works for regular menus registered by plugins (#Josh's answer only works for custom post types).
Essentially, you just need to register your submenu normally, but then hook into the 'submenu_file' filter to deregister it and optionally also set another submenu item to highlight instead.
function so3902760_wp_admin_menu() {
// Register the parent menu.
add_menu_page(
__( 'Parent title', 'textdomain' )
, __( 'Parent', 'textdomain' )
, 'manage_options'
, 'my_parent_slug'
, 'display_my_menu'
);
// Register the hidden submenu.
add_submenu_page(
'my_parent_slug' // Use the parent slug as usual.
, __( 'Page title', 'textdomain' )
, ''
, 'manage_options'
, 'my_hidden_submenu'
, 'display_my_submenu'
);
}
add_action( 'admin_menu', 'so3902760_wp_admin_menu' );
function so3902760_wp_admin_submenu_filter( $submenu_file ) {
global $plugin_page;
$hidden_submenus = array(
'my_hidden_submenu' => true,
);
// Select another submenu item to highlight (optional).
if ( $plugin_page && isset( $hidden_submenus[ $plugin_page ] ) ) {
$submenu_file = 'submenu_to_highlight';
}
// Hide the submenu.
foreach ( $hidden_submenus as $submenu => $unused ) {
remove_submenu_page( 'my_parent_slug', $submenu );
}
return $submenu_file;
}
add_filter( 'submenu_file', 'so3902760_wp_admin_submenu_filter' );
Yes, this can be done (well, technically, it would be more like registering the whole thing and then removing the menu item later), but It would just be easiest (I think) to check for parameters in the $_GET super-global to indicate that the user wishes to edit a specific item.
For example, you could have a page that lists items to edit, and clicking 'edit' only adds the item's ID to the current URL(query-string).
In the function that displays this page, if ID is defined, give them the page to edit that item.
Otherwise, give them the list view. That's how posts, pages, and other custom post types do it.
add_submenu_page with parent slug = null
OR
add_submenu_page with menu title = null
use this code for creating new page without adding in menu
add_action( 'admin_menu', 'register_newpage' );
function register_newpage(){
add_menu_page($appname, $appname, 'administrator','custompage', 'custom');
remove_menu_page('custom');
}
function custom()
{
echo "hai";
}
Note: This solution doesn't automatically set the current menu and submenu item. If you want to highlight a particular menu as current when the hidden page is viewed, see my other answer.
From the answers that come before me, you can see that there are many ways to do this. However, there is another way that I think may be the best.
Loading the page differently based on the value of a $_GET query var is one option, but it may not be what some people are looking for.
The suggestions regarding add_submenu_page() are on the right track, but each of the previous suggestions have problems. Setting $menu_title to null doesn't keep the menu item from being displayed, it just makes it so the link doesn't have any text. The link still takes up some room in the menu though, so it looks funny. Setting the $parent_slug to null doesn't have this problem, but I noticed that the page's HTML title doesn't display the $page_title text.
My solution was to set $parent_slug to a fake menu slug, like 'i_dont_exist'. The menu item won't be displayed, and when viewing the admin screen the page title will be filled out properly.
add_submenu_page(
'_doesnt_exist'
,__( 'Page title', 'textdomain' )
,''
,'manage_options'
,'menu_slug'
,'display_my_menu'
);
Yes. It is very possible to make a page cannot be reach via submenu, or even the main menu in the WP admin panel. See the code snippet below.
function myplugin_render_edit_page() {
// Code contains the UI for edit page.
}
/**
* Manage menu items and pages.
*/
function myplugin_register_admin_page() {
global $_registered_pages;
$menu_slug = plugin_basename('myplugin.php');
$hookname = get_plugin_page_hookname($menu_slug,'');
if (!empty($hookname)) {
add_action($hookname, 'myplugin_render_edit_page');
}
$_registered_pages[$hookname] = true;
}
add_action('admin_menu', 'myplugin_register_admin_page');
Hopefully, this will help.
Create sub menu page and parent slug leave it empty like this:
// Create page were you can add new users.
public function add_create_user_menu() {
add_submenu_page(
'',
'Create User',
'Create User',
'manage_options',
'create-user',
array( $this, 'add_create_user_page' )
);
}
You can access it like this:
Add New
I've tried all of the suggestions here but with various issues associated with each.
The WordPress codex for add_submenu_page now gives the correct answer, which is to use options.php as your parent slug. I tried the trick of using a made up name but that gives permissions errors, equally use of null at various locations either causes the menu text to simply be missing (but still clickable) or for the browser title to go missing.
Using options.php worked and I've not seen any issues as a result of its use.
Using add_submenu_page with a parent of NULL definitely works, however if you want to keep the non-linked page associated with a particular menu (say a custom post type menu), you have to use a variation of #Boopathi's answer:
function my_hidden_submenu_page(){
//add the submenu page the usual way
add_submenu_page('edit.php?post_type=custom-type', 'My Page Title', 'My Page Title', 'manage_options', 'my-page-slug', 'my_page_callback');
//then remove it
remove_submenu_page('edit.php?post_type=custom-type','my-page-slug');
}
add_action('admin_menu', 'my_hidden_submenu_page');
It looks as though the two actions would cancel each other out, however remove_submenu_page does not unregister the callback function; it merely removes the link.
This way when someone is viewing your non-linked page, the correct navigation menu (our custom post type menu in this example) will still show as active.
One of the problems I found with merely adding null as the parent slug for a sub menu item is that if you're currently viewing that specific page the submenu itself won't display (at least it didn't for me (along with the page title not showing).
What I did was add an empty span element inside the menu title and use jquery to traverse the parent elements and hide it.
It seems this need is still valid for nowadays version.
I am using WordPress 5.3.2 and I used the following methods to remove the parent named menu from the submenu.
add_action( 'admin_menu', 'submenus' );
function submenus()
{
global $submenu;
$parent_slug = 'parent_slug_name';
// remove parent named menu from submenu because it is always the first one in the submenu array, so the offset is 0 and remove just 1
array_splice( $submenu[$parent_slug], 0, 1 ); // with reindex
// or unset( $submenu[$parent_slug][0] ); // without reindex
}
Hope it helps others who want to achieve the same goal.
About php array_splice()
this method could be found in the source of WP function remove_submenu_page() which is available since WP 3.1.0
Edit / Added
Apart from submenu, parent menu could also be updated in similar way.
For parent menu, the global variable is $menu.
example for reference:
add_action( 'admin_menu', array( $this, 'modify_menu_title' ) );
function modify_menu_title() {
global $menu;
$page = 'some-page-slug';
$new_menu_title = 'New Title Name';
foreach( $menu as $key => $value ) {
if( $menu[$key][2] === $page ) {
$menu[$key][0] = $new_menu_title;
}
}
}
I find you can do it by reusing the insert id, like so:
add_menu_page( 'User AS Packages', 'User AS', 'manage_options', 'myplugin/editaspackages.php', 'UserASPackages', '', 8);
add_menu_page( 'User ARP Packages', 'User ARP', 'manage_options', 'myplugin/editarppackages.php', 'UserARPPackages', '', 8);
add_menu_page( 'AS Packages', 'AS Packages', 'manage_options', 'myplugin/ars-s2.php', 'ARPPackages', '', 8);
The last 3 using position 8 and the last one overrides the two before so the two before do not appear.
