我想表單數據到表寄宿插入到mysql數據庫的寄宿家庭。我查了很多次，但沒有錯誤。我不知道是否我的插入查詢錯誤？插入我的寄宿表中沒有錯誤，沒有工作
傢伙在這裏是PHP代碼中插入表格值到寄宿表
<?php
include("connection.php");
$sessid = $_SESSION["sess_id"];
$resultowner = mysqli_query($conn, "select * from owner where owner_id =$sessid");
$rowowner = mysqli_fetch_assoc($resultowner);
if(isset($_POST["addbtn"]))
{
$name = $_POST["name"];
$postcode = $_POST["postcode"];
$city = $_POST["city"];
$state = $_POST["state"];
$address = $_POST["address"];
$capacity = $_POST["capacity"];
$room = $_POST["room"];
$bathroom = $_POST["bathroom"];
$amenity = $_POST["amenity"];
$status= $_POST["status"];
$price= $_POST["price"];
$category = $_POST["category"];
$sessid = $_SESSION["sess_id"];
$result = mysqli_query($conn,"insert into homestay(homestay_name,homestay_postcode,homestay_city,homestay_state,homestay_address,homestay_capacity,homestay_rooms,homestay_bathrooms,homestay_amenities,homestay_blacklist_status,homestay_price_perday,category_id,owner_id)values('$name',$postcode,'$city','$state','$address',$capacity,$room,$bathroom,'$amenity','$status',$price,$category,$sessid)");
if($result)
echo "<script type='text/javascript'>alert('$name');</script>";
}
?>
的connection.php鏈接到寄宿數據庫
<?php
$conn = mysqli_connect("localhost","root","","homestay");
session_start();
?>
這是形式的詳情

這裏是寄宿表
homestay_id int(10)
homestay_name varchar(50)
homestay_address varchar(50)
homestay_postcode int(5) unsigned zerofill
homestay_state varchar(20)
homestay_city varchar(20)
homestay_capacity int(5)
homestay_rooms int(3)
homestay_bathrooms int(3)
homestay_amenities varchar(50)
homestay_blacklist_status varchar(50)
homestay_price_perday double
category_id int(11)
owner_id int(11)
這裏是錯誤>>複製項目「1-4」關鍵「category_id_3」 –
