Question

我想在变量（likes）中保存喜欢的数量（$likes）并将其打印在状态帖子（$statuslist）中，如果没有{foreach则可能1}}循环因为我试过，我不能把$statuslist放在循环中但代码只能部分工作。它回应了喜欢的数量，但只有当每个状态帖子获得0,1,2,3等喜欢时。我不想要这个。我想在 EACH 帖子上回应其他人的喜欢数量为此，foreach循环和fetch_object可以正常工作，但如果我使用foreach循环，我必须将$statuslist放在其中，我不希望这样。<登记/> 那么有什么解决方案吗？

MySQL的：

$statusQuery = $conn->query("
        SELECT 
        status.id,
        COUNT(status_likes.id) AS likes,
        GROUP_CONCAT(users.username SEPARATOR '|') AS liked_by
        FROM status

        LEFT JOIN status_likes
        ON status.id = status_likes.status

        LEFT JOIN users
        ON status_likes.user = users.id

        GROUP BY status.id 
    ");

    $likes = "";
    while($row = mysqli_fetch_array($statusQuery, MYSQLI_ASSOC)){
        $likes = $row["likes"];
    }

状态发布：

$statuslist .= '<div id="status_'.$statusid.'" class="status_boxes">';
$statuslist .= '<div>'.$statusDeleteButton.'<p id="status_date">';
$statuslist .= '<b>Post: </b>'.$postdate.'</p>'.$user_image.';
$statuslist .= '<p id="status_text">'.$data.'</p>';
$statuslist .= '.$shareButton.''.$likeButton.''.$likes.' people like it.
$statuslist .= '</div>'.$status_replies.'</div>';

修改：
我已经尝试过并且工作了，但我无法将喜欢的数量保存到可变数据中并在$statuslist中回显它。

while($row = $statusQuery -> fetch_object()){
        $statuses[] = $row;
    }

foreach ($statuses as $status) {
    echo $status->likes;
}

Answer 1

require("MyPost.php"); // Needs to be at the top of the script!!

$statusQuery = $conn->query("
    SELECT 
    status.id,
    COUNT(status_likes.id) AS likes,
    GROUP_CONCAT(users.username SEPARATOR '|') AS liked_by
    FROM status

    LEFT JOIN status_likes
    ON status.id = status_likes.status

    LEFT JOIN users
    ON status_likes.user = users.id

    GROUP BY status.id 
");

$posts = array();

while($row = mysqli_fetch_array($statusQuery, MYSQLI_ASSOC)){

    $mypost = new MyPost($row);
    array_push($posts, $mypost);

}


foreach ($posts as $key => $post_value) {
    // echo $post_value->id
    echo $post_value->display_post();
}

通过 MyPost.php 创建一个新文件，并将其放在与脚本相同的文件夹中。 MyPost.php 的内容必须是以下代码。

class MyPost
{

    // You can change these to private if you would like (change public to private)
    public $statusDeleteButton = "DELETE_BUTTON_HERE";
    public $likeButton = "LIKE_BUTTON_HERE";
    public $shareButton = "LIKE_BUTTON_HERE";


    // Keep public
    public $id, $postdate, $user_image, $liked_by, $likes, $data, $status_replies;

    // Code that is ran when a new MyPost object is created.
    public function __construct($array)
    {
        // I am assuming you are getting these from the sql also? 
        //If you are then you can delete these variables.
        $this->user_image = "";
        $this->postdate = "";
        $this->status_replies = "";
        $this->data = "";

        // Set the variables (Don't delete)
        foreach ($array as $key => $value) {
            $this->$key = $value;
        }
    }

    // Return the string for the post.
    public function display_post()
    {
       return '<div id="status_'.$this->id.'" class="status_boxes">
            <div>'.$this->statusDeleteButton.'<p id="status_date">
                <b>Post: </b>'.$this->postdate.'</p>'.$this->user_image.
                '<p id="status_text">'.$this->data.'</p>'.
                $this->shareButton.''.$this->likeButton.''.$this->likes.' people like it.
        </div>'.$this->status_replies.'</div>';
    }
}
