While 循环只检索一个结果 [英] While loop only retrieving one result

问题描述

更新:似乎仍然无法弄清楚.如果有人能伸出援手，将不胜感激^^.

UPDATE: Still can't seem to figure it out. If anyone can lend a hand, it would be appreciated ^^.

我遇到了一个问题，我不确定我的代码在哪里崩溃.我有一个关注"功能，您可以在其中关注不同的注册用户.您关注的用户的用户 ID 存储在一个数组 (follower_array) 中.它从数组中检索每个成员，但是对于每个跟随的成员而不是显示所有内容，它只显示来自每个成员的 1 个最新成员.

I am having a problem and I'm not sure where my code is breaking down. I have a 'follow' function where you can follow different registered users. Their userID's of who you followed are stored in an array (follower_array). It's retrieving each member from the array, but of each member that's followed instead of displaying all the content, it's only displaying the 1 latest one from each member.

$broadcastList= "";

if ( $follower_array != "" ) {

  $followArray = explode(",", $follower_array);
  $followCount = count($followArray);   
  $i = 0;
  $broadcastList .= "<table>";

  foreach( $followArray as $key => $value ) {

    $i++;
    $sqlName = mysql_query("
        SELECT username, fullname 
          FROM members 
         WHERE id='$value' 
         LIMIT 1
    ") or die ("error!");

    while ( $row = mysql_fetch_array($sqlName) ) {
      $friendUserName = substr($row["username"],0,12);
    }

    $sqlBroadcast = mysql_query("
        SELECT mem_id, bc, bc_date, device 
          FROM broadcast 
         WHERE mem_id='$value' 
      ORDER BY bc_date ASC 
         LIMIT 50
    ") or die ("error!");

    while ( $bc_row = mysql_fetch_array($sqlBroadcast) ) {
      $mem_id  = $bc_row['mem_id'];
      $bc      = $bc_row['bc'];
      $dev     = $bc_row['device'];
      $bc_date = $bc_row['bc_date'];
      $broadcastList .= "<td><a href='member.php?id=' .$value. ''>
      $friendUserName</a> &bull; $when_bc &bull; Via: $dev <b>$bc</b></td></tr>";
    }
    broadcastList .= "</table>";
  }
}

因此，它正在完全检索成员，但不会超过他们的最新广播".任何见解将不胜感激..谢谢！

So, it's retrieving the members entirely, but not more than their single latest "broadcast." Any insight would be appreciated.. thank you!

推荐答案

情况如下:

while( $row = some_next_result_function() ){
    $result = $row["thing"];
}

每次都会覆盖 $result，所以你只会得到最后一个结果.

Is going to overwrite $result every time, so you'll only end up with the last result.

您需要制作一个列表并附加到它.

You need to make a list and append to it instead.
