当我尝试在ID字段中输入标记我的个人帖子(帖子ID:1932等)时,值总是打印为0,而不是数据库的值

该查询采用$\u请求的topic变量(通过单击链接生成)

这是我的密码:

 <?php

 require_once 'connect.php';

 $topic = $_REQUEST['topic'];

 // Build the SELECT statement
 $select_posts =
 "SELECT p.topic, p.title, p.pic_id, p.snippet, p.content, p.author_id, p.date FROM posts p WHERE p.topic =  '" . $topic . "' OR p.topic='Admin' ORDER BY p.date DESC";

 // Run the Query
 $result = mysql_query($select_posts);

 ?>

 <?php
   $post_count=0;
   while ($post_count<10 && $posts = mysql_fetch_array($result)) {
       $posts_row = sprintf(
           '<entry>
               <headline>%s</headline>
                    <pic><img class=inlinepic src=/Sustenance/assets/post-pics/%d.jpg></pic>
                    <snippet class=on id="%d snippet">%s</snippet>
                    <readmore id="readmore%d" class=on onclick=readmore("%d")>Read More</readmore>
                    <content id="%d" class="less">%s
                        <readmore class=on onclick=readless(%d)>Show Less</readmore>
                    </content>
                    <byline>
                        <by>by</by>
                        <author>%s</author>
                    </byline>
            </entry>',
       $posts['topic'], $posts['title'], $posts['pic_id'], $posts['post_id'], $posts['snippet'], $posts['post_id'], $posts['post_id'], $posts['post_id'], $posts['content'], $posts['post_id'], $posts['author_id']);
       echo $posts_row;
       $post_count++;
  }
 ?>

你必须把

$divid=$posts['post_id'];

while
循环中。现在的方式是,在循环头中第一次分配值之前,它尝试获取一个值
$posts['post_id']
,因此它是
0
,并且永远不会更改(因为它从未被重新分配)。

不应该$divid=$posts['post_id'];在while循环中?这是一个很好的观点!我把它移回了应该放的地方。然而,这似乎并没有解决问题。
