使用特定編號編輯數據

我正在爲通知編輯按鈕，但編輯它時，所有通知都會更改。我只想編輯特定的ID。這裏是我的代碼：使用特定編號編輯數據

<?php 
    if(mysql_num_rows($query_announcement) > 0) 
    { 
     $row = mysql_num_rows($query_announcement); 
     for($x = 1; $x<= $row; $x++){ 

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

       <button type="button" data-toggle="modal" data-target="#modal_addAnnouncementEdit" 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>'; 
    } 
    ?>

編輯MODAL：

MY更新查詢：

<?php 
require"../includes/library/DB.php"; 

$title = $_POST['addAnnouncement_title_edit']; 
$description = $_POST['addAnnouncement_description_edit']; 
$location = $_POST['addAnnouncement_location_edit']; 
$date_start = $_POST['addAnnouncement_dateStart_edit']; 
$date_end = $_POST['addAnnouncement_dateEnd_edit']; 
$date_created = date("Y-m-d H:i:s"); 
$query_announcement = mysql_query("SELECT * FROM announcement"); 
$get_announcement = mysql_fetch_assoc($query_announcement); 
$insert_announcement = mysql_query("UPDATE `loanapplicationform`.`announcement` SET `announce_name` = '$title', `announce_description` = '$description', `announce_location` = '$location', 
`date_start` = '$date_start', `date_end` = '$date_end' WHERE `announcement`.`id`=`$id`"); 

?>

請幫助我謝謝您的回答，我會很感激

你需要使用一個變量，而不是你的'where'子句中的'id'列，這就是爲什麼它的更新整個「id」列。通常有一個隱藏屬性 –

我已經將其更改爲$ id，。$ get_announcement ['id']但它不起作用。 @ Fred-ii- –

你沒有分配任何東西給它。 '$ id =「？」;'例如。 –

在你的MY UPDATE QUERY部分，你需要定義$id。

這是您的查詢：

$insert_announcement = mysql_query("UPDATE  
`loanapplicationform`.`announcement` SET `announce_name` = '$title', 
`announce_description` = '$description', `announce_location` = '$location', 
`date_start` = '$date_start', `date_end` = '$date_end' WHERE 
`announcement`.`id`=`$id`");

當執行它，它不知道什麼$id是。因此，它會將您的WHERE子句爲

...WHERE `announcement`.`id`=

而不是

...WHERE `announcement`.`id`='abc12345'

而當你只是簡單地用$get_announcement['id']取代$id將無法正常工作，因爲$get_announcement['id']只包含你的循環中值。

您需要定義$id你定義的所有其他變量，例如：

$id = $_POST['addAnnouncement_id_edit']; 

$title = $_POST['addAnnouncement_title_edit']; 
$description = $_POST['addAnnouncement_description_edit']; 
... 
...
