原文在此
仔細比較此外掛關於 ‘資料庫更新’ 的檔案, 可能有部分必須修正.
1. Vault.txt
2. root/vault_db_update.php
以下的修改, 提供您參考:
開啟：
vault_db_update.php
尋找：
$sql[] = "INSERT INTO " . $table_prefix . "vault_exchange (stock_id, stock_name, stock_desc, stock_price, stock_previous_price, stock_best_price, stock_worst_price) VALUES (1, 'Vault_action_name_1', 'Vault_action_desc_1', 100, 100, 100, 100)";
$sql[] = "INSERT INTO " . $table_prefix . "vault_exchange (stock_id, stock_name, stock_desc, stock_price, stock_previous_price, stock_best_price, stock_worst_price) VALUES (2, 'Vault_action_name_2', 'Vault_action_desc_2', 200, 200, 200, 200)";
$sql[] = "INSERT INTO " . $table_prefix . "vault_exchange (stock_id, stock_name, stock_desc, stock_price, stock_previous_price, stock_best_price, stock_worst_price) VALUES (3, 'Vault_action_name_3', 'Vault_action_desc_3', 300, 300, 300, 300)";
取代為：
$sql[] = "INSERT INTO " . $table_prefix . "vault_exchange (stock_id, stock_name, stock_desc, stock_price, stock_previous_price, stock_best_price, stock_worst_price, chairman) VALUES (1, 'Vault_action_name_1', 'Vault_action_desc_1', 100, 100, 100, 100, 2)";
$sql[] = "INSERT INTO " . $table_prefix . "vault_exchange (stock_id, stock_name, stock_desc, stock_price, stock_previous_price, stock_best_price, stock_worst_price, chairman) VALUES (2, 'Vault_action_name_2', 'Vault_action_desc_2', 200, 200, 200, 200, 2)";
$sql[] = "INSERT INTO " . $table_prefix . "vault_exchange (stock_id, stock_name, stock_desc, stock_price, stock_previous_price, stock_best_price, stock_worst_price, chairman) VALUES (3, 'Vault_action_name_3', 'Vault_action_desc_3', 300, 300, 300, 300, 2)";
開啟：
Vault.txt
尋找：
INSERT INTO phpbb_vault_exchange (stock_id, stock_name, stock_desc, stock_total, stock_price, stock_previous_price, stock_best_price, stock_worst_price) VALUES (1, 'Vault_action_name_1', 'Vault_action_desc_1', 30, 100, 100, 100, 100,2 );
INSERT INTO phpbb_vault_exchange (stock_id, stock_name, stock_desc, stock_total, stock_price, stock_previous_price, stock_best_price, stock_worst_price) VALUES (2, 'Vault_action_name_2', 'Vault_action_desc_2', 30, 200, 200, 200, 200,2 );

取代為：
INSERT INTO phpbb_vault_exchange (stock_id, stock_name, stock_desc, stock_total, stock_price, stock_previous_price, stock_best_price, stock_worst_price, chairman) VALUES (1, 'Vault_action_name_1', 'Vault_action_desc_1', 30, 100, 100, 100, 100, 2);
INSERT INTO phpbb_vault_exchange (stock_id, stock_name, stock_desc, stock_total, stock_price, stock_previous_price, stock_best_price, stock_worst_price, chairman) VALUES (2, 'Vault_action_name_2', 'Vault_action_desc_2', 30, 200, 200, 200, 200, 2);
INSERT INTO phpbb_vault_exchange (stock_id, stock_name, stock_desc, stock_total, stock_price, stock_previous_price, stock_best_price, stock_worst_price, chairman) VALUES (3, 'Vault_action_name_3', 'Vault_action_desc_3', 30, 300, 300, 300, 300, 2);
