Question

当您按下“加载更多”按钮时，我希望将限制提高。我已经有了正确的设置来获取一个数字，当您用AJAX按下按钮时，这个数字会一直加2。

唯一的问题是我不能将该数字放在OOP类中的查询中。现在，echo $ count工作正常，将数字放入限制查询中一定有问题。当我用简单的整数替换极限查询时，一切工作正常。

我希望有人能找到问题所在...

<?php
            require_once '../bootstrap.php';
            if (!empty($_POST['postNewCount'])) {

                $post = new Post();
                $count = $_POST['postNewCount'];
                //settype($postNewCount, 'integer');

                echo $count;
                $count = $post->setPostNewCount($count);

            } else {
                echo 'loading';
            }

class Post
{
  protected $postNewCount;


    public function getPostNewCount()
    {
        return $this->postNewCount;
    }


    public function setPostNewCount($postNewCount)
    {
        $this->postNewCount = $postNewCount;

        return $this;
    }



 public function selectSearchAndLimit()
    {
        $limitPosts = $this->postNewCount;
        $conn = Db::getInstance();
        $innerhtml = $this->checkIfSearchIsEmpty();

        $result = $conn->prepare('SELECT posts.id 
        as post_id, users.id 
        as user_id, posts.visibility, posts.message, posts.image, 
        posts.filter, posts.`color1`, posts.`color2`, posts.`color3`, 
        posts.`color4`, users.`firstname`, users.`lastname`, 
        users.`email`, posts.timePost 

        FROM posts 
        JOIN users on users.id = posts.usersId 
        WHERE posts.visibility = 1 
        AND posts.message 
        LIKE :innerhtml 
        ORDER BY posts.id DESC  
        LIMIT :limitPosts ');

        $result->bindParam(':limitPosts', $limitPosts);
        $result->bindValue(':innerhtml', '%'.$innerhtml.'%');
        $result->execute();

        return $result;
    }
}

从加载更多按钮获取查询“限制”
