Controller
public function commentlist(){
$conn = mysqli_connect("localhost","root","","finance");
$memberId = 1;
$sql = "SELECT * FROM tbl_comment INNER JOIN signup ON tbl_comment.u_id = signup.id";
$result = mysqli_query($conn, $sql);
$record_set = array();
while ($row = mysqli_fetch_assoc($result)) {
array_push($record_set, $row);
}
mysqli_free_result($result);
mysqli_close($conn);
echo json_encode($record_set);
}
public function commentadd(){
$conn = mysqli_connect("localhost","root","","finance");
$u_id = $this->session->userdata('log_in')['id'];
$u_image = $this->session->userdata('log_in')['image'];
$commentId = isset($_POST['comment_id']) ? $_POST['comment_id'] : "";
$comment = isset($_POST['comment']) ? $_POST['comment'] : "";
$postID = isset($_POST['tmp']) ? $_POST['tmp'] : "";
$name = array();
$name[0] = $this->session->userdata('log_in')['f_name'];
$name[1] = $this->session->userdata('log_in')['l_name'];
$commentSenderName = implode(" ", $name);
$sql = "INSERT INTO tbl_comment(post_id, parent_comment_id,u_id,u_image,comment,comment_sender_name,date) VALUES ('" . $postID . "','" . $commentId . "','" . $u_id . "','" . $u_image . "','" . $comment . "','" . $commentSenderName . "','" . $date . "')";
$result = mysqli_query($conn, $sql);
if (! $result) {
$result = mysqli_error($conn);
}
echo $result;
}

我认为您的代码很复杂，因为不需要在评论表中保存用户图像，名称，您只需要使用评论ID（自动递增），帖子ID，用户ID和评论即可。您会收到特定帖子的所有评论，您应该通过该帖子的ir获取。示例：-当用户单击特定帖子时，假设其帖子ID为1，则单击此链接时，您必须将带有该帖子ID的请求传递到评论表，如果此条件为true，则查询将与此评论ID匹配重定向页面以查看所有评论并显示它们。控制者查询：-$ this-> model_name-> function_name（$ id）;在模型中$ this-> db-> where（'post_id'，$ id）;$ this-> db-> get（'comment_table'）-> result_array（）;
