WordPress的插件沒有創建表 <p>register_activation_hook（<strong>FILE</strong>，array（$ this，'create_phone_order_db'））;</p>

我正在開發需要創建一個表在數據庫這裏是我的代碼插件，請幫助代碼沒有顯示任何錯誤，而不是在創建表

public function create_phone_order_db() { 

    global $wpdb; 


$charset_collate = $wpdb->get_charset_collate(); 
$table_name = $wpdb->prefix . 'phone_orders'; 
    require_once(ABSPATH . 'wp-admin/includes/upgrade.php'); 
    $sql = "CREATE TABLE IF NOT EXISTS " . $table_name . " ( 
     id INT NOT NULL AUTO_INCREMENT, 
     billing_country VARCHAR(100) NOT NULL, 
     billing_first_name VARCHAR(50) NOT NULL, 
     billing_last_name VARCHAR(50) NOT NULL, 
     billing_company VARCHAR(50) NOT NULL, 
     billing_address_1 VARCHAR(120) NOT NULL, 
     billing_address_2 VARCHAR(120) NOT NULL, 
     billing_city VARCHAR(50) NOT NULL, 
     billing_state VARCHAR(40) NOT NULL, 
     billing_postcode VARCHAR(8) NOT NULL, 
     billing_email VARCHAR(25) NOT NULL, 
     billing_phone VARCHAR(20) NOT NULL,

     shipping_address_2 VARCHAR(120) NOT NULL, 
     shipping_city VARCHAR(50) NOT NULL, 
     shipping_state VARCHAR(50) NOT NULL,

     order_comments VARCHAR NOT NULL, 
     shipping_method VARCHAR NOT NULL, 
     payment_method VARCHAR NOT NULL, 
     _wpnonce VARCHAR NOT NULL, 
     _wp_http_referer VARCHAR NOT NULL, 
     PRIMARY KEY (id) 
     ) " . $charset_collate . ";"; 
    dbDelta($sql); 
}

您確定該表在您的數據庫中不存在嗎？請注意，你有'CREATE TABLE IF NOT EXISTS ...' – vitozev

是不存在的..我認爲我創建的表太大了...... –

試着'echo $ sql;'並執行你的原始SQL phpMyAdmin，或者如果你沒有安裝phpMyAdmin，可以在這裏粘貼查詢。 – vitozev

據WordPress的Codex你應該做

class MyPlugin { 
     static function install() { 
      global $wpdb; 
      $table_name = $wpdb->prefix . 'my_table'; 

$charset_collate = $wpdb->get_charset_collate(); 

$sql = "CREATE TABLE $table_name (
    id mediumint(9) NOT NULL AUTO_INCREMENT, 
    time datetime DEFAULT '0000-00-00 00:00:00' NOT NULL, 
    name tinytext NOT NULL, 
    text text NOT NULL, 
    url varchar(55) DEFAULT '' NOT NULL, 
    UNIQUE KEY id (id) 
) $charset_collate;"; 

require_once(ABSPATH . 'wp-admin/includes/upgrade.php'); 
dbDelta($sql); 
     } 
    } 

    register_activation_hook(__FILE__, array('MyPlugin', 'install'));
