everyone!
I believe similar question have been asked already, but I had not found working solution.
The problem: I need a metabox for one exact page only.
The code I use to add a metabox is pretty simple:
function custom_meta_boxes(){
add_meta_box('custom_meta_1', 'About Us Main field','custom_meta_boxes_render',
'page','normal','high','');
}
If you look on the 4th parameter - 'page', this puts metabox on every page, so that I see it and can use it for every page I created when editing it. And I need to see it on about us page only (for example).
I`ve seen in some tutorials that instead of 'page' you can use an ID or a slug of page, but that did not work for me.
Therefore, I really need your help/advice on that.
Thanks a lot in advance.
Try to do it like this:
<?php
function custom_meta_boxes(){
global $post;
$postSlug = isset($post->slug) ? $post->slug : '';
if ($post->slug === 'about-us') {
add_meta_box(
'custom_meta_1',
'About Us Main field',
'custom_meta_boxes_render',
'page',
'normal',
'high',
''
);
}
}
And change about-us slug for that you want to add meta box.
I have repeatedly been trying to implement the Advanced Custom Fields (ACF) plugin in the Vantage theme (from AppThemes), but without any success. I've had extensive contact with the admin of ACF, on this subject, but unfortunately we did not succeed. He advised to ask here, maybe seek for a (paid) developer, to solve this problem.
Ok, so what am i trying?
I have created a custom field group and want to implement that field group within the listing form of Vantage. To do so i have read several docs, including: http://www.advancedcustomfields.com/resources/tutorials/creating-a-front-end-form/. To be complete, based on this i did the following in the Vantage theme folder:
I created 2 custom field groups, with the id's: 88 & 139.
In Wrapper.php i added the code: <?php acf_form_head(); ?>
In form-listing.php i created 2 custom hooks, 'product_custom' and 'product_custom2': <?php do_action( 'product_custom' ); ?> <?php do_action( 'product_custom2' ); ?>
In fuctions.php i created 3 functions:
add_action( 'wp_print_styles' , 'my_deregister_styles' , 100 );
function my_deregister_styles() {
wp_deregister_style( 'wp-admin' );
}
add_action( 'product_custom' , 'productfields' );
function productfields() {
$options = array(
'field_groups' => array('post' => '88' ),
'form' => false,
);
acf_form( $options );
}
add_action( 'product_custom2' , 'productfields2' );
function productfields2() {
$options2 = array(
'field_groups' => array('post' => '139' ),
'form' => false,
);
acf_form( $options2 );
}
This actually made the custom field group show up in the listing form of Vantage. However the following things keep going wrong:
Both field groups have a WYSIWYG field. However for some reason the WYSIWYG buttons and media button stop working
I cannot fill in any text in the first WYSIWYG field. Only the second one works for that matter.
No data is stored at all after saving the listing form. On advise of the ACF admin, i tried the following in the acf-master/core/api.php file:
// run database save first
if( isset($_POST['acf_save']) )
{
$txt="Hello world!";
echo $txt;
die();
However the string does not display after saving the listing form. So the if statement is not used...
4. To display the dataon the frontend, once they are saved, I guess the default wordpress codex can be used..
I tried to be as complete as possible;) Is there anybody who can help me any further? Paid assistance is also negotiable..
Thanks a lot in advance!

I have succeed on implementing ACF with vantage themes.
I add ACF form at vantage listing form and combine the vantage form with ACF form. with one button.
The data has been saved to database and can be called to displayed in listing area. Only add image button is not working from front-end but in back-end the button is working.
Adding <?php acf_form_head(); ?> to wrapper.php
Do this tutorial front end form help
Eliminate default vantage submit button in form-listing.php
Add this code in ACF api.php in function acf_form_head()
// allow for custom save
$post_id = apply_filters('acf_form_pre_save_post','va_after_create_listing_form', $post_id);
That's it, hope it work in your site.
Is that you want when someone visits the website that they are able to send info via the page they visits eg www.yoursite.com/listing/listing-name like probably an email or contact for more info relating to that business?
If not then you can simply add in the ACF data from the back-end i.e. dreamweaver etc onto single-listing.php and use the ACF tutorial on working with fields.
Hope this helps somewhat
Cheers
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 want to add a completely custom content type to the WordPress admin panel as per my image below. I don't believe this is called a plugin as I did a tutorial on those and they don't have an admin interface. I want to define a custom create/edit/delete screen for this content.
Is this possible?
What should I be searching for to get help on this?
I believe what you're looking for (as of Wordpress 3.0) is custom post types. There's quite a good tutorial on them here, however googling "wordpress custom post types" should provide a plethora of links.
http://codex.wordpress.org/Function_Reference/add_submenu_page is a good starting place to look. It will explain how to add new items into the menu.
Now, removing them is a different story. This function I wrote for one of my plugins removes entries from a submenu:
function cleanup_menu() {
global $submenu, $wpdb;
$new_submenu = array();
$remove = array( 'Cast Manager', 'Seating Manager', 'Download Reports', 'new report' );
foreach ($submenu['menuname'] as &$item) {
if ( ! in_array( $item[0], $remove ) ) { $new_submenu[] = $item; }
}
$submenu['menuname'] = $new_submenu;
}
So in your case, "menuname" would be changed to "Posts", I would guess. There's also a function remove_submenu_page, but there's no documentation on it and I haven't looked into it.
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.
