Question

根据显示约会是否可用的状态。我希望显示状态是否可用，用户将通过指向新页面的链接重定向，如果约会不可用，则状态将被隐藏。不知道我哪里错了..

</thead>
          <tbody>
          <?php
          if(is_array($appointmentdetails) || isset($displayAppointment)){
          foreach($appointmentdetails as $displayAppointment) { ?> 


          <tr>

            <td><?php print $displayAppointment['DOCTOR_LICENSE_NO']; ?></td>
            <td><?php print $displayAppointment['DOCTOR_FNAME']; ?></td>
            <td><?php print $displayAppointment['DOCTOR_LNAME']; ?></td>
            <td><?php print $displayAppointment['DOCTOR_EMAIL_ID']; ?></td>
            <td><?php print $displayAppointment['DOCTOR_PHONE']; ?></td>
            <td><?php print $displayAppointment['APPOINTMENT_DATE']; ?></td>
            <td><?php print $displayAppointment['APPOINTMENT_TIME']; ?></td>


   --> Here I want to display the given condition 

   <?php if($displayAppointment['APPOINTMENT_STATUS']=="Available")

                        { ?>    
                            <td><a href="input_user.php?APPOINTMENT_STATUS=<?php print $displayAppointment['APPOINTMENT_STATUS']; ?>"><?php print $displayAppointment['APPOINTMENT_STATUS']; ?></a></td>
                        <?php } 
                         else ?>
                        <?php {?>
                            <td><?php print $displayAppointment['APPOINTMENT_STATUS']; ?></td>
                        <?php}?>

      </tr>
      <?php } } ?>
                        </tbody>
      </table>

        </body>

Answer 1

在数据库/或列表中创建一个字段作为约会状态，如果约会可用，则将其设为true，否则为false。并在if else语句中使用它

if($displayAppointment['APPOINTMENT_STATUS'])
{
   echo "Appointment available" ; //or what ever your link
}
else
{
   echo "redirect";
}

Answer 2

在php代码中，在打开if括号之前放置语句echo。同样在if语句中，它应该是$ displayAppointment ['APPOINTMENT_STATUS']

<?php if($displayAppointment['APPOINTMENT_STATUS']=="Available")
   { 
  //put echo here
    echo 'APPOINTMENT_STATUS'; ?>
    <td><a href="input_user.php?APPOINTMENT_STATUS=<?php print $displayAppointment['APPOINTMENT_STATUS']; ?>"><?php print $displayAppointment['APPOINTMENT_STATUS']; ?></a></td>
     <?php } 
     else {?>
         <td> <input type="hidden" name="APPOINTMENT_STATUS" value="<?php print $displayAppointment['APPOINTMENT_STATUS'];?>" ></td>
     <?php}?>

Answer 3

This is Youre Code :
<td><?php print $displayAppointment['APPOINTMENT_STATUS']; ?></td>
                            <?php}?>

Need space after <?php 
Right Code :

 <td><?php print $displayAppointment['APPOINTMENT_STATUS']; ?></td>
                        <?php }?>

PHP中的IF-Else条件
