Question

<?php

require "conn.php";

$GroupName = "test";
$sql_query ="SELECT G_number FROM Group WHERE Group_Name like '$GroupName';";
$row = mysqli_query($conn,$sql_query);
$result = $row->get_result(); //error comes up here




$sql_query2 =$conn->prepare("SELECT Question, User_name,date FROM Post WHERE Group_number = '$result';");
$sql_query2->execute();
$sql_query2->bind_result($Question,$User_name,$date);

$post = array();

while($sql_query2->fetch()){

$temp = array();
$temp['Question'] = $Question;
$temp['User_Name'] = $User_name;
$temp['Date'] = $date;

array_push($post,$temp);



}
echo json_encode($post);
?>

当我将域放入url时，我试图将json打印到html，但是我的日志中不断出现此错误：

“ PHP致命错误：未捕获错误：调用成员函数布尔值中的get_result（） /home/f7215owv4qzh/public_html/post_retrieval.php:8“

有人知道我在做什么错吗？我已经搜索了修复程序，并将语法更改为无效。

Answer 1

尝试这种方式

$result = $row->fetch_array();

OR

$result =mysqli_fetch_array($row)

未捕获的错误：在布尔值
