               else{
                echo '<tr><td colspan="8" align="center"><h3>No Announcement</h3></td></tr>';

    ?>

/这是我的代码，但是当我运行它时，我只会得到具有相同ID的公告，而不是我创建的所有公告。 请帮助谢谢

Answer 1

您正在循环播放公告，但没有拉出下一个公告。

for($x = 1; $x<= $row; $x++){
//Pull next record
$row = mysql_num_rows($query_announcement);

如果将其更改为for循环上方的代码，则会启动。 数据将被拉出，显示，然后将再次循环。

Answer 2

您一次只能提取数据

for($x = 1; $x<= $row; $x++){
$get_announcement= mysql_fetch_assoc($query_announcement);

Answer 3

尝试以下操作：您需要遍历各行，并使用每一行来显示它们。

<?php
   $query_announcement = mysql_query("SELECT * FROM announcement");
   $get_announcement = mysql_fetch_assoc($query_announcement);
?>
<?php


 if($get_announcement){

  while($row = mysql_fetch_array($get_announcement)) {

               $html = '<tr>';
               $html .= '<td>'.$row['id'].'</td>';
               $html .= '<td>'.$row['announce_name'].'</td>';
               $html .= '<td>'.$row['announce_description'].'</td>';
               $html .= '<td>'.$row['announce_location'].'</td>';
               $html .= '<td>'.date('M d,Y', strtotime($row['date_start'])).'</td>';
               $html .= '<td>'.date('M d,Y', strtotime($row['date_end'])).'</td>';
               $html .= '<td>'.date('M d,Y', strtotime($row['date_added'])).'</td>';
               $html .= '<td width="15%">

              <button type="button" class="btn btn-default" title="Edit"><span class="fa fa-pencil"></span></button>
              <button type="button" class="btn btn-default" title="Delete" ><span class="fa fa-trash-o"></span></button>
              </td>';
              $html .= '</tr>';

              echo $html;
              }
           }
               else{
                echo '<tr><td colspan="8" align="center"><h3>No Announcement</h3></td></tr>';
              }
