I have a Wordpress plugin which I've named 'Solve Maths'. I want this plugin name to be displayed only at the Admin header of the Arthur alone for easy access.
I used the admin_head action hook but once I installed the plugin, the system tells me my plugin has generated these number of characters at the header.
<?php function Solve_Maths{ echo "<a href='Solve_Maths.php'>Solve Maths</a>";} add_action('admin_head','Solve_Maths');?>
The Solve_Maths.php is the name of the main plugin file with the header information. I want this file name in the tag to be shown at the admin header of the user and should execute the file when the link is linked. Thank you all for your help.
This is not the correct way to do it. Please check the WordPress Codex and refer to the function add_node: https://codex.wordpress.org/Function_Reference/add_node
add_action( 'admin_bar_menu', 'toolbar_link_to_mypage', 999 );
function toolbar_link_to_mypage( $wp_admin_bar ) {
$args = array(
'id' => 'my_page',
'title' => 'My Page',
'href' => 'http://example.com/my-page/',
'meta' => array( 'class' => 'my-toolbar-page' )
);
$wp_admin_bar->add_node( $args );
}

I am trying to figure out how to create a Wordpress plugin that adds a page to the Wordpress website on which it is installed.
I came up with the following which works and adds the page.
However, it's far from what I am trying to achieve:
How to change the entire page? Not just the content? Right now, it has all the header and footer and navbar.
How to have PHP code in the page, not just static content?
Is it possible to have everything under a url (https://some-url.com/my-plugin/) routed to this same page?
For example:
https://some-url.com/my-plugin/ -> run my page
https://some-url.com/my-plugin/foo/ -> run my page
https://some-url.com/my-plugin/foo2/abc/ -> run my page
etc.
<?php
/**
* Plugin Name: MyPlugin
* Plugin URI: myplugin.com
* Description: MyPlugin
* Version: 1.0
* Author: Mike
* Author URI: myplugin.com
*/
define( 'MYPLUGIN__PLUGIN_DIR', plugin_dir_path( __FILE__ ) );
function create_page() {
$post_data = array(
'post_title' => 'Test of my plugin',
# How to change the entire page? Not just the content?
# Also, how to have PHP code in the page, not just static content?
'post_content' => 'Place all your body content for the post in this line.',
'post_status' => 'publish', // Automatically publish the post.
'post_type' => 'page', // defaults to "post".
'post_name' => 'my-plugin', // url slug (will 'slugify' post_title if empty) https://some-url.com/my-plugin-page?/
);
// Lets insert the page now.
wp_insert_post( $post_data );
}
function plugin_activation() {
create__page();
}
function plugin_deactivation() {
}
register_activation_hook( __FILE__, 'plugin_activation' );
register_deactivation_hook( __FILE__, 'plugin_deactivation' );
You want wp_insert_post()
Usage:
$postarr = [
'post_title' => 'My Page Title', // <title> tag
'post_content' => '<p>page content</p>', // html for page content
'post_type' => 'page', // blog post is default
'post_name' => 'my-plugion-page', // url slug (will 'slugify' post_title if empty) https://some-url.com/my-plugion-page?/
];
$post_id = wp_insert_post($postarr);
For example, in your $postarr if you want it to be a page (not a blog post), use 'post_type' => 'page'. For the page title 'post_title' => 'My New Page' and so on.
See: https://developer.wordpress.org/reference/functions/wp_insert_post/
Updated for additions to user question
If you don't want it to follow the theme templates, then you'll need to hook into the 'page_template' filter and use a template file you create in your plugin. See: https://wordpress.stackexchange.com/questions/3396/create-custom-page-templates-with-plugins
Depends on the situation, you can add code in your custom template, use shortcodes or custom Gutenberg blocks. You can use Advanced Custom Fields on in the Admin UI and use get_field() in your code, etc. You have lots of options in WordPress. Once you have a custom template you can just add regular PHP in there.
Yes, but you'll need to use regex and create rewrite rules using add_rewrite_rule(). Here are links that help with creating rewrite rules in WordPress

When the admin is logged in and is in front end area, there is a small dropdown of the quick menus. How can I add link to plugins page here?
function my_tweaked_admin_bar() {
global $wp_admin_bar;
$wp_admin_bar->add_menu( array(
'id' => 'plugins',
'title' => 'Plugins',
'href' => get_site_url().'/wp-admin/plugins.php',
'parent'=> 'site-name'
));
}
add_action( 'wp_before_admin_bar_render', 'my_tweaked_admin_bar' );
Just paste this code in functions.php in your current theme's directory.
For more information check WordPress Codex:
https://codex.wordpress.org/Plugin_API/Action_Reference/wp_before_admin_bar_render
can any one help to solve a problem?
Just For example:
If I have one site wpnpl.com.np
I wannt to give access to the files of a plugin like if they type
wpnpl.com.np/npl they will access the features of the plugin
How to do this???Any Idea
First create plugin short code in your plugin core file
function bartag_func( $atts ) {
$atts = shortcode_atts( array(
'foo' => 'no foo',
'baz' => 'default baz'
), $atts, 'bartag' );
return "foo = {$atts['foo']}";
}
add_shortcode( 'bartag', 'bartag_func' );
After that create a page in wp-admin with slug npl and content with
[bartag foo="bar"]
I'm using Wordpress (with multisite capabilities enable) to create my network.
When I add a new site, it's needed to create some posts, pages and menus into this new site.
I need to create a default form (with WP Contact Form 7 plugin) too.
While I'm looking for this answer, I'm doing this manually: add the new site, create posts, pages, menus and default contact form, then I give the user and password to new user.
Thanks!!
It can be done with a Must Use Plugin and the action hook wpmu_new_blog.
<?php
/**
* Plugin Name: Create custom content on site creation
*/
add_action( 'wpmu_new_blog', 'custom_items_so_23276440', 10, 6 );
function custom_items_so_23276440( $blog_id, $user_id, $domain, $path, $site_id, $meta )
{
switch_to_blog( $blog_id );
$default_page = array(
'post_title' => 'Default title',
'post_content' => '<h2>Default content</h2>',
'post_status' => 'publish',
'post_type' => 'page'
);
// insert the post into the database
wp_insert_post( $default_page );
restore_current_blog();
}
To create the menus, use the functions wp_create_nav_menu and wp_update_nav_menu_item. I'm not sure about the contact form, you'll have to inspect the database to see how CF7 does it, maybe it has some handy function to create a form programatically...
There's another technique using the file wp-content/install.php explained in How to Create a Custom WordPress Install Package?
I would like to create a file in the Wordpress theme, where i will add my own code, edit profile, show profile information, and perhaps an ability to insert posts / meta data programmatically.
So it needs to be www.mysite.com/profile.php or www.mysite.com/profile/
I do not want to use Buddy Press or any other plugin.
I know how the template system works, i do not want a page template.
It will probably be a class, later on, i do not want to change .htaccess file, and if i must i would appreciated filter function how to do this from functions.php
Basically just a simple .php file i can link to, located in theme root.
include('../../../wp-load.php');
and write any code i would like to.
Any creative solution that is not too "hacky" would be appreciated.
Spent around 2 days googling bashing my head on this, before i decided to ask question.
Thank you very much.
Ok, I managed to do this, took me 2 days to figure it out. Here is how I managed to do it:
Make a plugin folder.
In that plugin folder make 1x php file. so index.php
Ok so first thing we need to register plugin I did it like this, in your index.php paste
this code.
function activate_profile_plugin() {
add_option( 'Activated_Plugin', 'Plugin-Slug' );
/* activation code here */
}
register_activation_hook( __FILE__, 'activate_profile_plugin' );
Then we need a function when you register a plugin only once register profile pages.
function create_profile_page( $title, $slug, $post_type, $shortcode, $template = null ) {
//Check if the page with this name exists.
if(!get_page_by_title($title)) {
// if not :
$page_id = -1;
$page_id = wp_insert_post(
array(
'comment_status' => 'open',
'ping_status' => 'open',
'post_content' => $shortcode,
'post_author' => 1, // Administrator is creating the page
'post_title' => $title,
'post_name' => strtolower( $slug ),
'post_status' => 'publish',
'post_type' => strtolower( $post_type )
)
);
// If a template is specified in the function arguments, let's apply it
if( null != $template ) {
update_post_meta( get_the_ID(), '_wp_page_template', $template );
} // end if
return $page_id;
}
}
Ok so we created function which programatically register pages. It has 5 paramethers.
is Title
Slug
Post type
Shortcode.
Template
For the shortcode template you need to make a shortcode with the complete page output
and add it as a parameter to this function, so for registration page it will be a shortcode with the registration forms etc.
For example :
function registration_shortcode(){
echo 'Wellcome to Registration page';
}
add_shortcode('registration_output', 'registration_shortcode');
Next thing we need to call it once only when plugin loads.
so we do this :
function load_plugin() {
if ( is_admin() && get_option( 'Activated_Plugin' ) == 'Plugin-Slug' ) {
delete_option( 'Activated_Plugin' );
/* do stuff once right after activation */
// example: add_action( 'init', 'my_init_function' );
create_profile_page('Registration', 'registration', 'page', '[registration_output]');
create_profile_page('Profile', 'profile', 'page', '[profile_shortcode]');
create_profile_page('Profil Edit', 'profile-edit', 'page', '[edit_shortcode]');
}
}
add_action( 'admin_init', 'load_plugin' );
Ok so this will execute only once when plugin loads and it will create 3 Pages, which are Profile, Registration and Profile Edit.
And that's it, you have your front-end user profile blank pages, and you can write page output in shortcodes ,create more pages, put any forms or elements you like and create decent profile (which doesn't have any stuff you don't need in it like plugins. )
Hope this helps, it was painful for me to figure this out. Cheers!
