I receive the code complete, but I don’t know how to make the Post Type loads the MetaBox when creating a new Post, here is the Post Type:
if ( ! function_exists('cpt_campaign_details') ) {
// Register Custom Post Type
function cpt_campaign_details() {
$labels = array(
'name' => _x( 'Campaign Details', 'Post Type General Name', 'text_domain' ),
'singular_name' => _x( 'Campaign Detail', 'Post Type Singular Name', 'text_domain' ),
'menu_name' => __( 'Campaign Details', 'text_domain' ),
'name_admin_bar' => __( 'Campaign Detail Post', 'text_domain' ),
'archives' => __( 'Campaign Details Archives', 'text_domain' ),
'attributes' => __( 'Campaign Detail Attributes', 'text_domain' ),
'parent_item_colon' => __( 'Parent Campaign Detail:', 'text_domain' ),
'all_items' => __( 'All Campaign Details', 'text_domain' ),
'add_new_item' => __( 'Add New Campaign Detail', 'text_domain' ),
'add_new' => __( 'Add New', 'text_domain' ),
'new_item' => __( 'New Campaign Detail', 'text_domain' ),
'edit_item' => __( 'Edit Campaign Detail', 'text_domain' ),
'update_item' => __( 'Update Campaign Detail', 'text_domain' ),
'view_item' => __( 'View Campaign Detail', 'text_domain' ),
'view_items' => __( 'View Campaign Detail', 'text_domain' ),
'search_items' => __( 'Search Campaign Details', 'text_domain' ),
'not_found' => __( 'Not found', 'text_domain' ),
'not_found_in_trash' => __( 'Not found in Trash', 'text_domain' ),
'featured_image' => __( 'Featured Image', 'text_domain' ),
'set_featured_image' => __( 'Set featured image', 'text_domain' ),
'remove_featured_image' => __( 'Remove featured image', 'text_domain' ),
'use_featured_image' => __( 'Use as featured image', 'text_domain' ),
'insert_into_item' => __( 'Insert into Campaign Detail', 'text_domain' ),
'uploaded_to_this_item' => __( 'Uploaded to this Campaign Detail', 'text_domain' ),
'items_list' => __( 'Campaign Details list', 'text_domain' ),
'items_list_navigation' => __( 'Campaign Details list navigation', 'text_domain' ),
'filter_items_list' => __( 'Filter Campaign Details list', 'text_domain' ),
);
$args = array(
'label' => __( 'Campaign Detail', 'text_domain' ),
'description' => __( 'This post is used to manage all Campaign details', 'text_domain' ),
'labels' => $labels,
'supports' => array( 'title', 'thumbnail', 'page-attributes' ),
'taxonomies' => array( 'category', 'post_tag' ),
'hierarchical' => true,
'public' => true,
'show_ui' => true,
'show_in_menu' => true,
'menu_position' => 5,
'menu_icon' => 'dashicons-megaphone',
'show_in_admin_bar' => true,
'show_in_nav_menus' => true,
'can_export' => true,
'has_archive' => true,
'exclude_from_search' => false,
'publicly_queryable' => true,
'capability_type' => 'page',
);
register_post_type( 'campaign_details', $args );
}
add_action( 'init', 'cpt_campaign_details', 0 );
}
And here is the Meta Box:
class CampDeta_Resu {
public function __construct() {
if ( is_admin() ) {
add_action( 'load-post.php', array( $this, 'init_metabox' ) );
add_action( 'load-post-new.php', array( $this, 'init_metabox' ) );
}
}
public function init_metabox() {
add_action( 'add_meta_boxes', array( $this, 'add_metabox' ) );
add_action( 'save_post', array( $this, 'save_metabox' ), 10, 2 );
}
public function add_metabox() {
add_meta_box(
'CampDeta_Resu',
__( 'Campaign Details Results', 'text_domain' ),
array( $this, 'render_metabox' ),
'post',
'normal',
'default'
);
}
public function render_metabox( $post ) {
// Retrieve an existing value from the database.
$cade_re_results_numbers = get_post_meta( $post->ID, 'cade_re_results_numbers', true );
$cade_re_results_legend = get_post_meta( $post->ID, 'cade_re_results_legend', true );
// Set default values.
if( empty( $cade_re_results_numbers ) ) $cade_re_results_numbers = '';
if( empty( $cade_re_results_legend ) ) $cade_re_results_legend = '';
// Form fields.
echo '<table class="form-table">';
echo ' <tr>';
echo ' <th><label for="cade_re_results_numbers" class="cade_re_results_numbers_label">' . __( 'Number', 'text_domain' ) . '</label></th>';
echo ' <td>';
echo ' <input type="text" id="cade_re_results_numbers" name="cade_re_results_numbers" class="cade_re_results_numbers_field" placeholder="' . esc_attr__( '', 'text_domain' ) . '" value="' . esc_attr( $cade_re_results_numbers ) . '">';
echo ' <p class="description">' . __( 'This is the number that will appear over the legend. Example: 5.4M | 8.4M+ | 5x', 'text_domain' ) . '</p>';
echo ' </td>';
echo ' </tr>';
echo ' <tr>';
echo ' <th><label for="cade_re_results_legend" class="cade_re_results_legend_label">' . __( 'Legend', 'text_domain' ) . '</label></th>';
echo ' <td>';
echo ' <input type="text" id="cade_re_results_legend" name="cade_re_results_legend" class="cade_re_results_legend_field" placeholder="' . esc_attr__( '', 'text_domain' ) . '" value="' . esc_attr( $cade_re_results_legend ) . '">';
echo ' <p class="description">' . __( 'This text will go below the number and will define what the number means. Example: Total print reach | Visits | Engagement growth', 'text_domain' ) . '</p>';
echo ' </td>';
echo ' </tr>';
echo '</table>';
}
public function save_metabox( $post_id, $post ) {
// Sanitize user input.
$cade_re_new_results_numbers = isset( $_POST( 'cade_re_results_numbers' ) ) ? sanitize_text_field( $_POST( 'cade_re_results_numbers' ) ) : '';
$cade_re_new_results_legend = isset( $_POST( 'cade_re_results_legend' ) ) ? sanitize_text_field( $_POST( 'cade_re_results_legend' ) ) : '';
// Update the meta field in the database.
update_post_meta( $post_id, 'cade_re_results_numbers', $cade_re_new_results_numbers );
update_post_meta( $post_id, 'cade_re_results_legend', $cade_re_new_results_legend );
}
}
new CampDeta_Resu;
I googled “add a created metabox to a post type” and a lot of things like that and there is a lot of tutorials but unfortunately I can’t make it work.
