Search.php无法在找到项目时显示空白页

Question

我没有编码经验。。。请帮忙！！！搜索栏不会只给出空白页的结果！你能帮我解决这个问题吗！当搜索查询错误时，会按预期显示"未找到"消息，但在应该显示的时间没有结果。。请告诉我是否需要共享特定的代码

搜索.php

<?php 
$page_title = 'Searching';
require_once('includes/wrapper/header.php');
$string = '';
if($_POST['string'] != '') {
$string = htmlentities($_POST['string']);
} else {
header('Location: index.php');
}
$emoji = New Read();

?>
<div class="hero">
<div>
<h2><?php echo $string; ?> Emoji</h2>
<p>
You are currently searching for <?php echo $string; ?> emoji
</p>
</div>

<form class="form-inline" method="POST" action="search.php">
<div class="form-group">
<div class="input-group">
<input type="text" class="form-control input-lg" id="search" placeholder="Search Emoji... eg: Heart" name="string">
</div>
</div>
<button type="submit" class="btn searchbtn btn-lg btn-default btn-red">Search Emoji</button>
</form>
<div class="banner-ad">
<?php 
require_once('includes/wrapper/banner_ad.php');
?>
</div>
</div>

<section id="#people">
<div class="container">
<div class="emoji-content">
<?php 
$items = $emoji->search_emoji($string);
if(!empty($items)) {
foreach($items as $item) {
echo '<a class="copy" data-clipboard-text="&#x' . $item['unicode'] . '"><span class="emoji"><img src="assets/img/emoji/' . $item['unicode'] . '.png" width="70px" alt="' . $item['name'] . '"></span></a>';
} } else {
echo '<center><h2>No emoji matched your search terms....</center></h2>';
}?>
</div>
</div>



<?php require_once('includes/wrapper/footer.php'); ?>
