Question

我正在更新两列，即visastatus和当前日期。当我只更新我的visastatus列时，它工作正常但是当我应用这个查询时，两个列都在更新，那么它使我的visastatus 0和当前日期也没有更新。我的查询有问题吗？

    <?php  if(isset($_POST['submit']))
   {
   echo $radio = $_POST['radio'];
   $date_clicked = date('Y-m-d');
   $sql = "UPDATE user SET visastatus='$radio' and 
   currentdate='$date_clicked' WHERE id='$id'";  //this my update query.
    $query = mysqli_query($conn, $sql);
    if($query)
    {
        echo "<h4 style='color:green'>Action Performed Successfully....
  </h4>";
    }
    else
    {
        echo "<h4 style='color:red'>Failed.</h4>";
    }
    }
    ?>
   <form method="POST" action="" enctype="multipart/form-data">  

   <div class="col-xs-12 col-sm-6 col-md-6 col-lg-6" style="margin-top: 
    8px;" align="left">
      <label class="checkbox-inline tourist-rad">
         <input type="radio" name="radio" id="success" value="Successfull 
    done">Successfull
      </label>            
    &nbsp;&nbsp;&nbsp;
      <label class="checkbox-inline tourist-rad">
         <input type="radio" name="radio" id="decline" value="Visa 
    declined">Declined
      </label>
      &nbsp;&nbsp;&nbsp;


    </div>

    <div class="form-group">
         <button type="submit"  name="submit"  value="submit" class="btn 
    btn-primary" style="float: right;">Update Menu Item</button>
    </div><br><br><br><br><br><br>
    </body>
    </html>

Answer 1

试试这个。

UPDATE user SET visastatus=$radio,currentdate=$date_clicked WHERE id=$id

Answer 2

SQL更新查询的语法是

UPDATE table_name
SET column1 = value1, column2 = value2, ...
WHERE condition;

在查询中使用,代替AND

$sql = "UPDATE user SET visastatus='$radio', currentdate='$date_clicked' WHERE id='$id'";

使用今天的日期更新列currentdate
