我试图将关系表中 client_id 67 的所有结果复制到users_groups表中的所有其他用户，因此id的99,111,130 必须在关系表中具有相同的结果id 67 。
所以所有查询都运行正常，更新工作正常，删除也是如此，但Insert不会将任何数据插入到关系表中以获取我需要的其他ID。
我搜索了stackoverflow，但没有找到任何可能在我的示例中起作用的解决方案。
我需要从
复制数据的用户ID 67的关系表和结果signal_providers_relations TABLE
| id | client_id | provider_id | active_sp | subscription_sp | created_by | cr_datetime | ea_settings_active_sp | ea_settings_sp | up_datetime | sp_risk_allocation | sp_max_trades |

用户组表
users_groups TABLE
| id | user_id | group_id | user_role |
|----|---------|----------|-----------|
| 1 | 130 | 94 | 0 |
| 2 | 111 | 94 | 0 |
| 3 | 99 | 94 | 0 |
| 4 | 67 | 94 | 1 |
这是代码：
$user_role = intval($_POST['user_role']);
$userID = intval($_POST['user_id']);
$groupID = intval($_POST['group_id']);
$ea_settings = $_POST['ea_settings'];
// get users from group to apply ea_settings
$get_users = "SELECT a.group_name, b.user_id, b.user_role, b.group_id, c.email, c.ea_settings
FROM user_groups a
INNER JOIN users_groups b ON b.group_id = a.id
INNER JOIN www_users c ON c.id = b.user_id
WHERE a.id = '".$groupID."'";
$pr = fetch_array($get_users);
// get special user relations
$query2 = "SELECT a.*, b.user_role
FROM signal_providers_relations a
INNER JOIN users_groups b ON a.client_id = b.user_id
WHERE a.client_id = '".$userID."' AND b.user_role = '1'";
$pr2 = fetch_array($query2);
// get number of items from special user
$query3 = "SELECT count(a.id) as cnt
FROM signal_providers_relations a
INNER JOIN users_groups b ON a.client_id = b.user_id
WHERE a.client_id = '".$userID."' AND b.user_role = '1'";
$pr3 = fetch_array($query3);
// update all users where id = all id's from group, apply ea_settings to all id's from Special user
foreach ($pr as $key) {
foreach ($pr2 as $r) {
foreach ($pr3 as $s) {
$user_id = intval($key['user_id']); // id of all users
// update users
$update_users = "UPDATE www_users SET ea_settings = '".$ea_settings."' WHERE id = '".$user_id."'";
if (exec_query_confirm($update_users)) {
// first delete all user record in relations that are not special users, delete all record if user is have role = 0, and insert new data
if ($key['user_role'] == '0') {
$delete_relations = "DELETE FROM signal_providers_relations WHERE client_id = '".$user_id."'";
exec_query($delete_relations);
// loop through special user records and add to other users
for ($i=0; $i < $s['cnt']; $i++) {
// $s['cnt'] = 10 = number of records in relations table from id 67
$insert_new_values = "INSERT INTO signal_providers_relations (client_id, provider_id, active_sp, subscription_sp, created_by, cr_datetime, ea_settings_active_sp, ea_settings_sp, up_datetime, sp_risk_allocation, sp_max_trades)
VALUES ('".$user_id."', '".$r['provider_id']."', '".$r['active_sp']."', '".$r['subscription_sp']."', '".$r['created_by']."', '".$r['cr_datetime']."', '".$r['ea_settings_active_sp']."', '".$r['ea_settings_sp']."', '".$r['up_datetime']."', '".$r['sp_risk_allocation']."', '".$r['sp_max_trades']."')";
exec_query($insert_new_values);
}
}
} else {
$err = 61;
}
} // foreach
} // foreach
} // foreach
}
基本上我需要这个

答案 0 :(得分：1)
我认为您的主要问题是您实际上并不需要第三个查询或循环（foreach上的$pr2与for上的$s['cnt']相同）。你应该这样做：
// update all users where id = all id's from group, apply ea_settings to all id's from Special user
foreach ($pr as $key) {
$user_id = intval($key['user_id']); // id of all users
// update users
$update_users = "UPDATE www_users SET ea_settings = '".$ea_settings."' WHERE id = '".$user_id."'";
if (exec_query_confirm($update_users)) {
// first delete all user record in relations that are not special users, delete all record if user is have role = 0, and insert new data
if ($key['user_role'] == '0') {
$delete_relations = "DELETE FROM signal_providers_relations WHERE client_id = '".$user_id."'";
exec_query($delete_relations);
// loop through special user records and add to other users
foreach ($pr2 as $r) {
$insert_new_values = "INSERT INTO signal_providers_relations (client_id, provider_id, active_sp, subscription_sp, created_by, cr_datetime, ea_settings_active_sp, ea_settings_sp, up_datetime, sp_risk_allocation, sp_max_trades)
VALUES ('".$user_id."', '".$r['provider_id']."', '".$r['active_sp']."', '".$r['subscription_sp']."', '".$r['created_by']."', '".$r['cr_datetime']."', '".$r['ea_settings_active_sp']."', '".$r['ea_settings_sp']."', '".$r['up_datetime']."', '".$r['sp_risk_allocation']."', '".$r['sp_max_trades']."')";
exec_query($insert_new_values);
} // foreach
} else {
$err = 61;
}
} // if
} // foreach
