Question

我正在尝试根据某个条件更新值，但它不会更新。

这是我的代码

CREATE TABLESPACE TABLESPACE1992

CONSTRAINT TSLINEITEM_CHECK1 CHECK (TSL_QUANTITY >= 0),

CONSTRAINT TSLINEITEM_CHECK3 CHECK (TSL_TAX >= 0),
CONSTRAINT TSLINEITEM_CHECK4 CHECK (TSL_DISCOUNT BETWEEN 0.00 AND 1.00) ) TABLESPACE TABLESPACE1992;

我的样本数据就是这样

     foreach($div as $key=>$d){ 
        if(!$d['playingDate']){
           // SOME CODE GOES HERE.

        }else{

            // THIS CODE DEOSN'T UPDATE THE WEEKDAY
            $div[$key]['date']['weekday'] = $d['weekday'];
        }
     }

如您所见，第二项包含....... { id: 3209, playingDate: "2019-01-27", playingTime: "19:00", weekday: "Mån", date: { id: 94, gameLength: "90", startingDate: "2018-12-24", startingTime: "19:00", weekday: "Mån" }, { id: 3209, playingDate: "2019-01-27", playingTime: "19:00", weekday: "Sun", date: { id: 94, gameLength: "90", startingDate: "2018-12-24", startingTime: "19:00", weekday: "Mån" },，因此它也应该将工作日的数据也更新为weekday Sun，但没有。

Answer 1

您可以简单地使用

$ div [$ key] ['date'] ['weekday'] = date（'l'，strtotime（$ d ['playingTime']）））

这将自动返回您使用的$div内的工作日。让我知道是否有帮助。

对于这些类型的错误，请尝试转储数组，以便查看是否所有信息都在数组内。

Answer 2

您在foreach语句之前关闭else。它必须返回一个错误。

在脚本顶部添加此代码，以帮助您调试php：

ini_set('display_errors', 'On');
error_reporting(E_ALL | E_STRICT);
