如何在下拉菜单中输出MySql行

Question

我在此代码中遇到问题： `

                 <?php echo "Choose a date"; 
                     $reservation_date = $rm->retrieveReservation(); 
                              $data_date = array();
                              while($row_date = mysql_fetch_assoc($reservation_date)){
                                array_push($data_date, $row_date);
                                $dateOptions = ""
    .                               "<select class='filter'>"
    .                                  "<option value='<?php echo $row['date']  ; ?>'><?php echo $row['date']  ; ?></option>"
    .                               "</select>";
                                echo $dateOptions;
                              } ?>

                           ?>

我想在下拉菜单中输出Sql行值。提前谢谢！

您不必在此时回复<select>，您应该这样做：

 <?php echo "Choose a date"; 
                 $reservation_date = $rm->retrieveReservation(); 
                          $data_date = array();
                          $dateOptions = "<select class='filter'>";
                          while($row = mysql_fetch_assoc($reservation_date)){
                            array_push($data_date, $row_date);
                            $dateOptions = "<option value='". $row['date']."'>". $row['date'] ."</option>";
                          } ?>
                          $dateOptions = "</select>";
                          echo $dateOptions;
                       ?>

Answer 2

这应该有效：

echo "<select class='filter'>";
while($row = mysql_fetch_assoc($reservation_date)){
    echo "<option value='".$row['date']."'>".$row['date']."</option>";
}
echo "</select>";

您需要在循环之外使用select标记。你的PHP中也有一堆语法错误。

 <?php echo "Choose a date"; 
       echo "<select class='filter'>";
       $reservation_date = $rm->retrieveReservation(); 
              $data_date = array();
              while($row_date = mysql_fetch_assoc($reservation_date)){
                  array_push($data_date, $row_date);
                  $dateOptions = "<option value='{$row['date']}'>{$row['date']}</option>";
                  echo $dateOptions;
              } 
       echo  "</select>";
 ?>

这段代码可能适合你。
