Question

基本上我想要两个表，其中每个人都有Confirmed = 1，另一个表有Confirmed = 0.

我现在有这个SQL查询

 $result = mysqli_query($con,"SELECT * FROM tbl_booking WHERE $row[Confirmed] = 1");

但我一直在

Notice: Undefined variable: row in C:\xampp\htdocs\test.php on line 19

Warning: mysqli_fetch_array() expects parameter 1 to be mysqli_result, boolean given in

该页面的其余代码

echo "<table border='1'>
<tr>
<th>ID</th>
<th>BookID</th>
<th>date</th>
<th>time</th>
<th>confirmed?</th>
</tr>";


while($row = mysqli_fetch_array($result) )
  { ?>
   <tr>
   <td> <?php echo $row['tbl_mem_id']; ?> </td>
   <td> <?php echo $row['BookID']; ?> </td>
   <td> <?php echo $row['date']; ?> </td>
   <td> <?php echo $row['time']; ?> </td>
   <td> <?php echo $row['Confirmed']; ?> </td>
   <td> <a href=delete.php?BookID=<?php echo $row['BookID']; ?> </a> Delete </td>
   <td> 
       <?php
       if ($row['Confirmed'] == 0) { ?>
       <a href=confirm.php?BookID=<?php echo $row['BookID']; ?> </a> Confirm </td> <?php } else { ?>
       <a href=deny.php?BookID=<?php echo $row['BookID']; ?> </a> Deny </td> <?php
       } ?>
   </tr> <?php
  } ?>
</table>

Answer 1

您是否真的尝试将$row['Confirmed']中的值放入查询中，还是只是尝试查询名为Confirmed的字段？如果后者试试这个：

$result = mysqli_query($con,"SELECT * FROM tbl_booking WHERE Confirmed= 1");

但是你也似乎将php中的表与if ($row['Confirmed'] == 0)区分开来，你可能需要在一个查询中获取所有数据：

$result = mysqli_query($con,"SELECT * FROM tbl_booking");

这不会像你最初要求的那样给你2张桌子。

你可以用这个创建2个html表：

<?php
$result = mysqli_query($con,"SELECT * FROM tbl_booking WHERE Confirmed = 1");
echo "<table border='1'>
<tr>
<th>ID</th>
<th>BookID</th>
<th>date</th>
<th>time</th>
<th>confirmed?</th>
</tr>";


while($row = mysqli_fetch_array($result) )
  { ?>
   <tr>
   <td> <?php echo $row['tbl_mem_id']; ?> </td>
   <td> <?php echo $row['BookID']; ?> </td>
   <td> <?php echo $row['date']; ?> </td>
   <td> <?php echo $row['time']; ?> </td>
   <td> <?php echo $row['Confirmed']; ?> </td>
   <td> <a href=delete.php?BookID=<?php echo $row['BookID']; ?> </a> Delete </td>
   <td> 

       <a href=deny.php?BookID=<?php echo $row['BookID']; ?> </a> Deny </td>

   </tr> <?php
  } ?>
</table>
<?php
echo "<table border='1'>
<tr>
<th>ID</th>
<th>BookID</th>
<th>date</th>
<th>time</th>
<th>confirmed?</th>
</tr>";

$result = mysqli_query($con,"SELECT * FROM tbl_booking WHERE Confirmed = 0 ");    
while($row = mysqli_fetch_array($result) )
  { ?>
   <tr>
   <td> <?php echo $row['tbl_mem_id']; ?> </td>
   <td> <?php echo $row['BookID']; ?> </td>
   <td> <?php echo $row['date']; ?> </td>
   <td> <?php echo $row['time']; ?> </td>
   <td> <?php echo $row['Confirmed']; ?> </td>
   <td> <a href=delete.php?BookID=<?php echo $row['BookID']; ?> </a> Delete </td>
   <td> 
       <a href=confirm.php?BookID=<?php echo $row['BookID']; ?> </a> Confirm </td>
   </tr> <?php
  } ?>
</table>

根据它们是否为0或1来制作两个表
