Php 如何存储单选按钮中的信息？

我希望能够存储单选按钮的信息，以便将它们发送到数据库。对于查询的每个结果，我有两个单选按钮。一个是主队，一个是客队。我希望能够计算出用户选择了什么，将其与游戏的实际赢家进行比较，然后相应地增加赢家/输家。现在我想我已经掌握了大部分的逻辑，但是我遇到了一个php错误，这是我一生都无法理解的。也许这里有人能帮我

 <form method="POST" action="<?= $_SERVER['PHP_SELF'] ?>">
 <select name="weekNo">
 <option value="1">week 1</option>
 <option value="2">week 2</option>
 <option value="3">week 3</option>
 <option value="4">week 4</option>
 <option value="5">week 5</option>
 <option value="6">week 6</option>
 <option value="7">week 7</option>
 <option value="8">week 8</option>
 <option value="9">week 9</option>
 <option value="10">week 10</option>
 <option value="11">week 11</option>
 <option value="12">week 12</option>
 <option value="13">week 13</option>

第219行是：

pg_execute($conn,"myquery",array_SESSION['league'],$_SESSION['username'],
            $week_no,$game_no, $pick);

---

您尚未正确定义要传递给

pg_execute（）

的数组

试一试

---

第219行=（什么）确切地说？我不是在数219！那是哪一行？pg_execute（$conn，“myquery”，array_SESSION['league']，$SESSION['username']，$week_no，$game_no，$pick）；据我们所知，在您发布的内容上方可能还有50行。

array\u SESSION['league']

尝试

$\u SESSION['league']

或将其预先定义为数组-如果-它是数组的一部分。还要确保

session_start（）确实已加载。
pg_execute($conn,"myquery",array_SESSION['league'],$_SESSION['username'],
            $week_no,$game_no, $pick);

pg_execute($conn, 
           "myquery", 
           array( $_SESSION['league'],
                  $_SESSION['username'],
                  $week_no, 
                  $game_no, 
                  $pick)
          );
