PHP通过我的查询将多个会话变量插入MySQL

Question

I'm trying to insert the values my session is currently holding into my mysql table.

$insert_sql = 'INSERT INTO booked_rooms (date_start, date_end, adults, children, fk_room_id, title, first_name, last_name, address, city, state_province, zip_postal, telephone, email) 
VALUES ('.$_SESSION['date_start'].$_SESSION['date_end'].$_SESSION['adults'].$_SESSION['children'].$_SESSION['room_id'];', $title , $first_name , $last_name , $address , $city , $state , $zip , $telephone , $email)';

$insert = mysqli_query($con, $insert_sql) or die ($mysqli_error());

It should work, but I'm not sure how to use the $_session variables in this context

Answer 1

You have some mistakes in your query. try like this

$insert_sql = 'INSERT INTO booked_rooms (date_start, date_end, adults, children, fk_room_id, title, first_name, last_name, address, city, state_province, zip_postal, telephone, email) 
VALUES ("'.$_SESSION['date_start'].'","'.$_SESSION['date_end'].'","'.$_SESSION['adults'].'","'.$_SESSION['children'].'","'.$_SESSION['room_id'].'", "$title" ," $first_name" , "$last_name" , "$address" , "$city" , "$state" , "$zip" , "$telephone" , "$email")';

Answer 2

Issues in your query:

• You need to split your SESSION values in commas.
• Use quotes for string values.
• Don't know what is it? $mysqli_error() you need to remove $ sign.

Modified Query:

$insert_sql = "INSERT INTO booked_rooms (date_start, date_end, adults, children, fk_room_id, title, first_name, last_name, address, city, state_province, zip_postal, telephone, email) 
VALUES ('".$_SESSION['date_start']."','".$_SESSION['date_end']."','".$_SESSION['adults']."','".$_SESSION['children']."','".$_SESSION['room_id']."', '$title' ,'$first_name' , '$last_name' , '$address' , '$city' , '$state' , '$zip' , '$telephone' , '$email')";
