Create new wordpress roles plugin
Here is a step-by-step guide to creating a new WordPress roles plugin:
Step 1: Create a new plugin folder and file
Create a new folder in the wp-content/plugins
directory of your WordPress installation, and name it something like wp-roles-plugin
. Inside this folder, create a new file called wp-roles-plugin.php
.
Step 2: Define the plugin metadata
In the wp-roles-plugin.php
file, add the following code to define the plugin metadata:
<?php
/*
Plugin Name: WP Roles Plugin
Description: A plugin to manage custom WordPress roles
Version: 1.0
Author: Your Name
Author URI: https://yourwebsite.com
*/
Step 3: Create the plugin functionality
In the same file, add the following code to create the plugin functionality:
function wp_roles_plugin_init() {
// Register the custom roles
register_roles();
}
function register_roles() {
// Define the custom roles
$roles = array(
'editor' => array(
'name' => 'Editor',
'capabilities' => array(
'edit_posts' => true,
'edit_pages' => true,
'publish_posts' => true,
'publish_pages' => true,
'delete_posts' => true,
'delete_pages' => true,
),
),
'author' => array(
'name' => 'Author',
'capabilities' => array(
'edit_posts' => true,
'publish_posts' => true,
'delete_posts' => true,
),
),
'contributor' => array(
'name' => 'Contributor',
'capabilities' => array(
'edit_posts' => true,
),
),
);
// Register the custom roles
foreach ($roles as $role => $role_data) {
add_role($role, $role_data['name'], $role_data['capabilities']);
}
}
add_action('plugins_loaded', 'wp_roles_plugin_init');
This code defines three custom roles: editor
, author
, and contributor
. Each role has a set of capabilities that define what actions the user can perform.
Step 4: Add the plugin settings page
To add a settings page for the plugin, you can use the add_menu_page
and add_submenu_page
functions. Add the following code to the wp_roles_plugin_init
function:
function wp_roles_plugin_init() {
// Register the custom roles
register_roles();
// Add the plugin settings page
add_menu_page('WP Roles Plugin', 'WP Roles Plugin', 'manage_options', 'wp-roles-plugin', 'wp_roles_plugin_settings');
}
function wp_roles_plugin_settings() {
// Settings page content
?>
<div class="wrap">
<h1>WP Roles Plugin Settings</h1>
<form>
<table class="form-table">
<tr>
<th><label for="wp-roles-plugin-role">Custom Role:</label></th>
<td><input type="text" id="wp-roles-plugin-role" name="wp-roles-plugin-role" value="<?php echo get_option('wp-roles-plugin-role');?>"></td>
</tr>
</table>
<p class="submit"><input type="submit" name="submit" value="Save Changes"></p>
</form>
</div>
<?php
}
add_action('admin_menu', 'wp_roles_plugin_add_menu');
function wp_roles_plugin_add_menu() {
add_menu_page('WP Roles Plugin', 'WP Roles Plugin', 'manage_options', 'wp-roles-plugin', 'wp_roles_plugin_settings');
}
This code adds a settings page to the WordPress admin menu, with a form that allows users to input a custom role name.
Step 5: Save the plugin settings
To save the plugin settings, you can use the update_option
function. Add the following code to the wp_roles_plugin_settings
function:
function wp_roles_plugin_settings() {
// Settings page content
?>
<div class="wrap">
<h1>WP Roles Plugin Settings</h1>
<form>
<table class="form-table">
<tr>
<th><label for="wp-roles-plugin-role">Custom Role:</label></th>
<td><input type="text" id="wp-roles-plugin-role" name="wp-roles-plugin-role" value="<?php echo get_option('wp-roles-plugin-role');?>"></td>
</tr>
</table>
<p class="submit"><input type="submit" name="submit" value="Save Changes"></p>
</form>
</div>
<?php
if (isset($_POST['submit'])) {
update_option('wp-roles-plugin-role', $_POST['wp-roles-plugin-role']);
}
}
This code saves the custom role name input by the user to the wp-roles-plugin-role
option.
Step 6: Test the plugin
Save the wp-roles-plugin.php
file and upload it to your WordPress installation. Activate the plugin and navigate to the settings page to test the plugin functionality.
That's it! You have now created a new WordPress roles plugin.
