【问题描述】：

我正在尝试制作一些东西，以便显示数据库结果。问题是，它只显示 1 个结果。我希望它使用快速而肮脏的模板系统显示多个结果。另外，有没有办法让我的系统更好？也许是一个类或一个函数？我需要对此有所了解。非常感谢！

cp.php

<?php
require("db.php");
chdir("../"); // path to MyBB
define("IN_MYBB", 1);
require("./global.php");
$title = "********";
require("templates/header.php");

if($mybb->user['uid'])
{
    $uid = $mybb->user['uid'];
    // Active Tournaments
    // run queries, do all the brainwork
    // lets get the forum name
    $query = "SELECT tourneys.name, tourneys.date, tourneys.time
            FROM tourneys
            INNER JOIN players ON players.tid = tourneys.id
            WHERE players.forumname = {$uid}";
    $result = mysqli_query($conn, $query);
    // output data of each row
    while($row = mysqli_fetch_assoc($result)) {
        $activetournaments = "<td>". $row['name'] ."</td><td>" . $row['date'] . "</td><td>". $row['time'] ."</td>";
        // $team = mysqli_query($conn, "SELECT * FROM tourneys WHERE id=" . $row['tid'] . "");
        // $playing = mysqli_query($conn, "SELECT `` FROM tourneys WHERE id=" . $row['tid'] . "");
    }
}
else
{
        $error = "Only registered members may access this area.";
        include ('templates/error.php');
}
require ("templates/cp.php")
?>

模板/cp.php

<h2>Welcome back <?=$mybb->user['username']; ?>!</h2>
<?=$postrequirement?>
<h3>Active Tournaments</h3>
<table>
    <tr>
    <th>Name</th>
    <th>Date/time</th>
    <th>Team</th>
    <th>Playing as</th>
    <th>Options</th>
</tr>
<tr>
    <?=$activetournaments?>
    </table>
<hr />
<h3>Participated Tournaments</h3>
<table>
    <tr>
    <th>Position</th>
    <th>Name</th>
    <th>Date/time</th>
    <th>Team</th>
    <th>Played as</th>
    <th>Options</th>

<tr>
    <?=$participatedtournaments?>
    </table>

【解决方案1】：

我已将 $activetournaments 更改为使用 '.=' 附加到末尾。

while($row = mysqli_fetch_assoc($result)) {
    $activetournaments .= "<td>". $row['name'] ."</td><td>" . $row['date'] . "</td><td>". $row['time'] ."</td> ";
}

目前，对于每条记录，它正在覆盖 $activetournaments。您还可以使用 $activetournaments 作为数组，然后在模板中执行一段时间 / foreach。

【解决方案2】：

在您的 cp.php 中，您在每次执行时覆盖 $activetournaments，将您的代码更改为：

<?php
require("db.php");
chdir("../"); // path to MyBB
define("IN_MYBB", 1);
require("./global.php");
$title = "1ShotGG Tournaments | Control Panel";
require("templates/header.php");

if($mybb->user['uid'])
{
    $uid = $mybb->user['uid'];
    // Active Tournaments
    // run queries, do all the brainwork
    // lets get the forum name
    $query = "SELECT tourneys.name, tourneys.date, tourneys.time
            FROM tourneys
            INNER JOIN players ON players.tid = tourneys.id
            WHERE players.forumname = {$uid}";
    $result = mysqli_query($conn, $query);
    // output data of each row

    $activetournaments = '';

    while($row = mysqli_fetch_assoc($result)) {
        $activetournaments .= "<td>". $row['name'] ."</td><td>" . $row['date'] . "</td><td>". $row['time'] ."</td>";
        // $team = mysqli_query($conn, "SELECT * FROM tourneys WHERE id=" . $row['tid'] . "");
        // $playing = mysqli_query($conn, "SELECT `` FROM tourneys WHERE id=" . $row['tid'] . "");
    }
}
else
{
        $error = "Only registered members may access this area.";
        include ('templates/error.php');
}
require ("templates/cp.php")
?>

在您的模板/cp.php 中，您可以在此处添加</tr> 标签：

<tr>
    <?=$activetournaments?>
</tr>

你的新模板/cp.php：

<h2>Welcome back <?=$mybb->user['username']; ?>!</h2>
<?=$postrequirement?>
<h3>Active Tournaments</h3>
<table>
    <tr>
    <th>Name</th>
    <th>Date/time</th>
    <th>Team</th>
    <th>Playing as</th>
    <th>Options</th>
</tr>
<tr>
    <?=$activetournaments?>
</tr>
    </table>
<hr />
<h3>Participated Tournaments</h3>
<table>
    <tr>
    <th>Position</th>
    <th>Name</th>
    <th>Date/time</th>
    <th>Team</th>
    <th>Played as</th>
    <th>Options</th>
</tr>
<tr>
    <?=$participatedtournaments?>
    </table>
