Question

我正在使用Slim Framework v3，我在将数据从PHP传递到Slim模板时遇到问题。

例如：

$app->get('/user/{playerid}', function (Request $request, Response $response, array $args) {

    $playerid = $args['playerid'];

    $this->logger->info("Someone requested to see the score of the following player: [".$playerid."]");


    $db = Database::Instance();

    $row = $db->getPlayer($playerid);

    if ($row === false)
        return $this->renderer->render($response, 'dataNotFound.phtml', $args); // Not working: $playerid no displayed on HTML

    // Sets the player info on the template (this works)
    $args['name'] = $row['Name'];
    $args['language'] = $row['Language'];
    $args['score'] = $row['Score'];
    $args['card'] = $row['CardPngBase64'];

    return $this->renderer->render($response, 'user.phtml', $args);
});

工作模板（./templates/user.phtml）是：

<div class="container" style="margin-top: 4%">

    <?php
    if (isset($playerid) && isset($name) && isset($language) && isset($score) && isset($card)) : ?>
        <h1 class="jumbotron"><img align="center" src="<?php echo htmlspecialchars($card); ?>" /><br> <?= htmlspecialchars($name); ?>'s scores </h1>


        <div class="row text-center">
            <table class="table">
                <thead>
                <tr>
                    <th scope="col">Name</th>
                    <th scope="col">Country</th>
                    <th scope="col">Score</th>
                </tr>
                </thead>
                <tbody>
                <tr>
                    <td><?= htmlspecialchars($name); ?></td>
                    <td><?= htmlspecialchars(Locale::getDisplayRegion('-'.$language, 'en')); ?></td>
                    <td><?= htmlspecialchars($score); ?></td>
                </tr>
                </tbody>
            </table>
        </div>
    <?php else: ?>
        <h1 style="color: darkred">⛔️ Internal error: can't get the players data.</h1>
    <?php endif; ?>


    <div class="row" style="position: relative; margin-top: 50%">
        <a class="text-justify" href="http://responseable.csp.it">Go back to the main page</a>
    </div>

</div>

不工作模板（./templates/dataNotFound.phtml）是：

<div class="container" style="margin-top: 4%">
    <h1 class="jumbotron">‍♂️ Player not found ‍♀️</h1>

    <hr style="margin-top: 5%; margin-bottom: 5%">

    <div class="row">
        <p>‼️</p>
        <br>
        <p>The player <?php if(isset($playerid)) htmlspecialchars($playerid) ?> does not exists, please retry.</p>

    </div>

    <div class="row" style="position: relative; margin-top: 50%">
        <a class="text-justify" href="http://responseable.csp.it">Go back to the main page</a>
    </div>

</div>

因此，当数据库找到$playerid时，它会返回正确的渲染模板（user.phtml）并正确显示播放器数据。

但是当数据库找不到ID时，dataNotFound.phtml的呈现不起作用，特别是，我可以正确地看到所有HTML页面，但htmlspecialchars($playerid)缺失或为空。

这可能是一个小错误，但我找不到它。有人能帮我吗？但是，我是Slim的新人。

您可以做类似的事情。

路由器文件

$ this-> renderer-> args = array（ 'pid'=> $ args ['pid']，）;
返回$ this-> renderer-> render（$ response，“ user.phtml”）;
./ templates / dataNotFound.phtml

echo $ this-> args ['pid'];

Answer 2

routes.php

$app->get('/panel',function(Request $request, Response $response, array $args) use ($container){
    return $container->get('renderer')->render($response, 'panel.phtml', [
        'key' => "val"
    ]);
});

panel.phtml

<?php print_r($data); ?>
<!doctype html>
<html lang="en">
...
