Question

我的代码以状态“ to_do”显示列workouts中的所有数据，但它也重复了模式中的submit_abs按钮。 This is what happens

单击按钮可以正确更新状态。

  <?php # start of first php code

        $id = $_GET['id'];
        $sql = "SELECT * FROM workouts WHERE w_traineeid = '$id' AND w_status = 'to_do'";

        $results = mysqli_query($conn, $sql);
        $resultChecks = mysqli_num_rows($results);

        if ($resultChecks > 0) {
          while ($row = mysqli_fetch_assoc($results)) # end of first php code  
            {
              ?>
        <a href="php/mgmmsEditWO.php?id=<?php echo $row['w_traineeid']?>" class="btn btn-md" type="submit" id="submit_abs" name="submit_abs" data-toggle="tooltip" title="Confirm" style="background-color:#ecf0f1; color:black " ><span class="glyphicon glyphicon-ok"></span></a>
            <?php
            }
         } 
     ?>

之所以有多个按钮，是因为您正在循环创建它们。删除while循环，您将只获得一个按钮：

  <?php # start of first php code

        $id = $_GET['id'];
        $sql = "SELECT * FROM workouts WHERE w_traineeid = '$id' AND w_status = 'to_do'";
        /*$sql = "SELECT * FROM workouts";*/
        $results = mysqli_query($conn, $sql);
        $resultChecks = mysqli_num_rows($results);

        if ($resultChecks > 0) {  # end of first php code  
              ?>
        <a href="php/mgmmsEditWO.php?id=<?php echo $id?>" class="btn btn-md" type="submit" id="submit_abs" name="submit_abs" data-toggle="tooltip" title="Confirm" style="background-color:#ecf0f1; color:black " ><span class="glyphicon glyphicon-ok"></span></a>
            <?php
        } 
     ?>

您当前正在检查$results中的行数是否大于0，然后为每行添加一个按钮。

按钮重复但动作有效
