我正在尝试按条件在一个周期中输入产品，在数据库中每个产品str1都有一个字段，我希望str1 == 0的产品显示在一个块中，str1 == 1的产品显示在另一个，但由于某种原因，我的 1 号街区的标题重复了 - 1 号餐厅：

 <?php foreach ($content->items as $item): ?>

      <?php if($item['str1'] == 0): ?>

        <h2>Ресторан №1</h2> 
        <tr class="odd views-row-first">
            <td class="views-field views-field-nothing">
          <img src="<?= $item['content']['image'] ?>" width="120" height="80">
                                                        <br>
    </td><td><?= $item['content']['name'] ?></td>
    <td class="views-field views-field-commerce-unit-price views-align-left price">
    <?= $item['price']/* - ceil(($item['price'] * 7) / 100)*/ ?> руб.          </td>
<td class="views-field views-field-edit-quantity">
        <?= $item['count'] ?>
</td>

    <td class="views-field views-field-commerce-total views-align-left price">
  <span class=""><?= $item['price'] *  $item['count'] /*- ceil((($item['price'] *  $item['count']) * 7) / 100)*/ ?></span>           </td>
   <td class="text-center"><span class="glyphicon glyphicon-trash trash cart-delete" data-cart="<?= $item['id'] ?>" title="Удалить"></span></td>
    <td>
 </td>
</tr>

   <?php endif; ?>

   <?php if($item['str1'] == 1): ?>

    <h2>Ресторан №2</h2> 
  <tr class="odd views-row-first">
  <td class="views-field views-field-nothing">
   <img src="<?= $item['content']['image'] ?>" width="120" height="80">
    <br>

   <td class="views-field views-field-commerce-unit-price views-align-left price">

  <td class="views-field views-field-edit-quantity">

                                                        </tr>

我正在制作一个旋转木马，它使用键盘上的箭头和按钮移动滑块，它还有待完成，以便当您在键盘上单击左或右时，选择相应的滑块并以绿色突出显示，如何实现? 完整代码：

var lis = document.querySelectorAll('.images li');
var focused = document.querySelectorAll('.focused');



var width = 124;
var count = 1;
var left = 0;

var carousel = document.getElementById('carousel');
var list = carousel.querySelector('ul');
var listElems = carousel.querySelectorAll('.images li');

var position = 0;

function prev() {

  left = left + width;
  if (left > 0) {
    left = -868;
  }
  list.style.marginLeft = left + 'px';
};

function next() {

  left = left - width;
  if (left < -868) {
    left = 0;
  }
  list.style.marginLeft = left + 'px';
};

function eventKey(e) {
  switch (e.keyCode) {

    case 37:
      prev()
      break;

    case 39:
      next()
      break;

  }
}
addEventListener("keydown", eventKey);
ul {
  width: 9999px;
  transition: .3s ease;
  padding: 0;
}

li {
  display: inline-block;
  width: 90px;
  height: 200px;

#carousel {

我正在尝试将选择值放入变量中，但它给了我一个错误 - 未捕获的类型错误：无法读取 null 的属性“选项”，html 代码：

<select onchange="transaction()" id="сurrencyMain">

      <option value="0">Bitcoin</option>
      <option value="1023">Ether</option>
      <option value="1223">Bitcoin Cash</option>

    </select>

js代码：

function transaction() {
    var currencyMain = document.getElementById('currencyMain');
       var  addres_field = document.getElementById('address-field');
       var amount_bit = document.getElementById('amount-bit');
       var amount_rub = document.getElementById('amount-rub');
       var  description = document.getElementById('description');
       var transaction_fee = document.getElementById('transaction_fee');
       var  currencyTab = document.getElementById('currencyTab');

        var price = 0;
        price += parseInt(currencyMain.options[currencyMain.selectedIndex].value);
        currencyTab.innerHTML = price;

我试图从数据库中得出结论，我使用 PDO 连接到它，我尝试通过循环得出结论while，当我调用函数时，出现fetch()错误：

致命错误：在第 24 行的 /home/s/ser588nn/shop.ser588nn.beget.tech/public_html/models/News.php 中的布尔值上调用成员函数 fetch()

最有可能的是，当请求被执行时，它会query返回false，尽管请求正确地检查了所有内容。

模型 ： 

        public static function getNewsList()
        {
            //Запрос к БД
            $host = '127.0.0.1';
            $dbname = 'ser588nn_shop';
            $user = 'ser588nn_shop';
            $password = 'rootroot';
            $db = new PDO("mysql:host = $host;dbname = $dbname",$user, $password);

            $newsList = array();

                $result = $db->query('SELECT id, title, date, short_content FROM news ORDER BY date LIMIT 10');



        $i = 0;
        while($row = $result->fetch()) {
            $newsList[$i]['id'] = $row['id'];
            $newsList[$i]['title'] = $row['title'];
            $newsList[$i]['date'] = $row['date'];
            $newsList[$i]['short_content'] = $row['short_content'];
            $i++;
        }
        return $newsList;   
}

}
?>

控制器：

<?php

include_once ROOT. '/models/News.php';


class NewsController {
    public function actionIndex()
        {

            $newsList = array();
            $newsList = News::getNewsList();

            echo "<pre>";
            print_r($newsList);
            echo "</pre>";
            return true;
        }

    public function actionView($id)
    {
        echo "Список одной новости";
        return true;
    }


}

?>

有发送评论，需要检查div是否为空，如果为空则不发送评论。

$(document).ready(function() {
    $(".commen-text").submit(function() {
        if($(".KEmoji_Input div").val()=="") {
                $(this).remove();
        }
    });
 });



<div class="story-wrap">

    <div class="commen-text">
        <div style="width: 100%; margin-bottom: 30px; height: 80px !important;" id="{{STORY_ID}}but" onkeyup="postComment($('#{{STORY_ID}}but .KEmoji_Input div').html(),{{STORY_ID}},{{PUBLISHER_ID}},event);"></div>
        <p class="hideshow">Введите сообщение...</p>
