how to store wp editor in wordpress

1. Open your WordPress theme's functions.php file.

2. Use the add_meta_box function to create a meta box for your post or page editor.

function custom_editor_meta_box() {
    add_meta_box(
        'custom-editor-meta-box',
        'Custom Editor',
        'display_custom_editor_meta_box',
        'post', // Change 'post' to 'page' if you want it on pages
        'normal',
        'default'
    );
}
add_action('add_meta_boxes', 'custom_editor_meta_box');

1. Create a callback function to display the custom editor within the meta box.

function display_custom_editor_meta_box($post) {
    $content = get_post_meta($post->ID, '_custom_editor_content', true);
    wp_editor($content, 'custom_editor');
}

1. Save the custom editor content when the post is saved or updated.

function save_custom_editor_content($post_id) {
    if (array_key_exists('custom_editor', $_POST)) {
        update_post_meta(
            $post_id,
            '_custom_editor_content',
            sanitize_text_field($_POST['custom_editor'])
        );
    }
}
add_action('save_post', 'save_custom_editor_content');

1. Enqueue necessary scripts and styles for the editor to function properly.

function enqueue_custom_editor_scripts() {
    wp_enqueue_script('wp-editor');
    wp_enqueue_style('wp-editor');
}
add_action('admin_enqueue_scripts', 'enqueue_custom_editor_scripts');

1. Ensure that the wp_nonce_field function is used for security purposes.

function display_custom_editor_meta_box($post) {
    wp_nonce_field('custom_editor_nonce', 'custom_editor_nonce');
    $content = get_post_meta($post->ID, '_custom_editor_content', true);
    wp_editor($content, 'custom_editor');
}

1. Validate the nonce when saving the custom editor content.

function save_custom_editor_content($post_id) {
    if (
        !isset($_POST['custom_editor_nonce']) ||
        !wp_verify_nonce($_POST['custom_editor_nonce'], 'custom_editor_nonce')
    ) {
        return $post_id;
    }

    if (array_key_exists('custom_editor', $_POST)) {
        update_post_meta(
            $post_id,
            '_custom_editor_content',
            sanitize_text_field($_POST['custom_editor'])
        );
    }
}
add_action('save_post', 'save_custom_editor_content');
