一鍵保存如何在php / mysql中插入數據？

Question

我有帶player_name，runs，sixes，match_no，五十，數百，point_scored的表player_points。

我在上面的字段中創建表格，在其中插入奔跑次數和6，並使用奔跑次數和6來計算五十，數百和point_scored，在3六之后每增加6得分。 它的工作正常，但當我插入運行和六點並保存時，它僅以五十，一百和點計分的文本框顯示計算，而不保存到數據庫表中。 在我第二次保存它之后，將其保存到數據庫中。 我的代碼如下：

<tr><td colspan="9"><hr style="border:1px #999 dashed;"></td></tr>
 <tr>
  <th>Player</th>
  <th>Status</th>
  <th>Runs</th>
  <th>6's</th>
  <th>50's</th>
  <th>100's</th>
  <th>TP</th>
  <th>Action</th>
 </tr>
 <tr><td colspan="9"><hr style="border:1px #999 dashed;"></td></tr>

        $resultpl = $classObj->selectSql($condpl);
        //$recordcount = $classObj->getAffectedRows($result);
        $rowpl = $classObj->fetchData($resultpl);

假設您的類的getAffectedRows()方法確實從最后一條語句中獲取了受影響的行，則必須注意，SELECT並未對此進行設置，它將為零。

如果您想知道選擇了多少行，請使用mysqli_num_rows之類的東西。
