Question

我遇到了问题，我不知道如何解决它。

当交易进入负数或正数时，我有一个表从soll（负数）变为haben（正数）。

例： A队：'pes_teams_budget'= 5，'pes_teams_konto'= haben B队：'pes_teams_budget'= -5（手动改变以调整预算），'pes_teams_konto'= soll

A队向B队支付10欧元。

结果是： A队：'pes_teams_budget'= 5，'pes_teams_konto'= soll B队：'pes_teams_budget'= 5，'pes_teams_konto'= haben

它应该是： A队：'pes_teams_budget'= * - * 5 ，'pes_teams_konto'= soll B队：'pes_teams_budget'= 5，'pes_teams_konto'= haben

守则不会改变/显示负值。它只是保持正数，但从soll变为haben。

接下来的问题：看到这仍然是一个正数，它不再正常计算。

我希望有人可以帮助我，如果需要进一步的信息让我知道。谢谢

$receiver_data = get_team_data($receiver);
$receiver_budget = (int)$receiver_data['pes_teams_budget'];
$receiver_sql = "";
if($receiver_data['pes_teams_konto'] == "soll") {
    if( $receiver_budget < $ammount ) {
        $positiv_rest = $ammount - $receiver_budget;
        $disposer_sql = "UPDATE `d017ee3d`.`pes_teams` SET `pes_teams_konto` = 'haben', `pes_teams_budget` = '".(string)$positiv_rest."' WHERE `pes_teams`.`pes_teams_ID` =".$receiver.";";
    } elseif($receiver_budget == $ammount ) {
        $receiver_sql = "UPDATE `d017ee3d`.`pes_teams` SET `pes_teams_konto` = 'haben', `pes_teams_budget` = '0' WHERE `pes_teams`.`pes_teams_ID` =".$receiver.";";
    } else {
        $receiver_sql = "UPDATE `d017ee3d`.`pes_teams` SET `pes_teams_budget` = `pes_teams_budget` - '".$ammount_param."' WHERE `pes_teams`.`pes_teams_ID` =".$receiver.";";
    }
} else {
    $receiver_sql = "UPDATE `d017ee3d`.`pes_teams` SET `pes_teams_budget` = `pes_teams_budget` + '".$ammount_param."' WHERE `pes_teams`.`pes_teams_ID` =".$receiver.";";
}
$return['receiver_sql'] = $receiver_sql;
include('dbconnect.php');
$receiver_result = mysql_query($receiver_sql);
$return['receiver_result'] = $receiver_result;
if (!$receiver_result) {
    $return['error_receiver'] .= 'Ung&uuml;ltige Anfrage: '.mysql_error();
} else {
    $return['status_receiver'] = "success";
}   

//UPDATE mytab SET geld = geld - '200' WHERE id = $disposer
//UPDATE mytab SET geld = geld - '200' WHERE id = $receiver
//UPDATE `d017ee3d`.`pes_teams` SET `pes_teams_budget` = '100000001' WHERE `pes_teams`.`pes_teams_ID` =1;
//UPDATE `d017ee3d`.`pes_teams` SET `pes_teams_konto` = 'soll', `pes_teams_budget` = '1000' WHERE `pes_teams`.`pes_teams_ID` =1;

return $return;

为什么负数不会显示在.php / mysql表中？
