在HTML

我正在尝试从表中获取值并在html代码中显示值。

我在3个独立的php文件中工作。

这是Article.php文件,其中包含Article类:

public static function getInfobar() {
  $conn = new PDO( DB_DSN, DB_USERNAME, DB_PASSWORD ); //connecting to the db, the values are stored in config.php
  $sql = "SELECT 'title', 'subtitle', 'additional' FROM infobar WHERE id=1";
  $st = $conn->prepare ( $sql );
  $st->execute();
  $list = array();
  while ( $row = $st->fetch() ) { //storing the info inside the array.
    $infob = new Article( $row );
    $list[] = $infob;
}

  $conn = null;
    return ( array ( "results2" => $list));
}

从数据库中提取这些值后,我试图在HTML中显示它们。首先,我在前端处理程序中声明一个函数:index.php 编辑:使用开关调用该方法。

switch ( $action )
{
default:
homepage();
}

 function homepage() {
    $results = array();
    $results2 = array();

$data = Article::getList( HOMEPAGE_NUM_ARTICLES );
$data2 = Article::getInfobar();

$results['articles'] = $data['results'];
$results['totalRows'] = $data['totalRows'];
$results['pageTitle'] = "TITLE";
$results2['info'] = $data2['results2'];
require( TEMPLATE_PATH . "/homepage.php" );
}

之后,我试图在网页中显示这样的值:

<div class="row_item1">
  <?php foreach ( $results2['info'] as $infob ) { ?>
  <h1><?php echo htmlspecialchars($infob->title)?></h1>
  <p><?php echo htmlspecialchars($infob->subtitle)?></p>
  <p><?php echo htmlspecialchars($infob->additional)?></p>
  <?php } ?>
  <img src="" alt="">
</div>

但我得到的只是:

Result

我有点被困在这里,试图弄清楚代码的错误现在已经有一段时间了。请帮我解决这个问题。非常感谢。

更改您的查询

$sql = "SELECT 'title', 'subtitle', 'additional' FROM infobar WHERE id=1";

$sql = "SELECT title, subtitle, additional FROM infobar WHERE id=1";

对于用户要求。

我不确定。但是,它可以像这样。因为,我不知道流程,我建议你尝试这样一次。

public static function getFullInfobar() {
    .
    .
    $sql = "SELECT title, subtitle, additional FROM infobar";
    .
    .
}

$results3 = array();
$data3 = Article::getFullInfobar();

$results3['info'] = $data3['results3'];

<?php foreach ( $results3['info'] as $infob ) { ?>
<div class="row_item1">
  <h1><?php echo htmlspecialchars($infob->title)?></h1>
  <p><?php echo htmlspecialchars($infob->subtitle)?></p>
  <p><?php echo htmlspecialchars($infob->additional)?></p>
  <img src="" alt="">
</div>
<?php } ?>
