Unable to perform mysql table insertion - php

Question

I am unable to find any error shown but for some reason there is still an issue entering data into my table using SQL. I am new to coding and am not really sure what the issue is . I am sure that everything that needs to be passed and given is done but the mysql query is where it goes wrong and i am not able to understand why . could someone please help me out ?
<?php
session_start();
$conb = mysqli_connect("127.0.0.1","root","","demo");
$sellmail = $_SESSION['sellermaill'];
$buyermail = $_POST['email'];
$bid = $_POST["bid"];
$title = $_SESSION["Titleofp"];
echo"$sellmail";
echo"$buyermail";
echo"$bid";
echo"$title";
$mysqlbuy = "INSERT INTO buyer (Seller Mail,Buyer Mail,Bid,Product Title) VALUES ('$sellmail','$buyermail','$bid','$title')";
$mysqlsellq = mysqli_query($conb,$mysqlbuy);
if(!$mysqlsellq)
{echo "Your Bid has not been saved ";}
else echo "Your Bid has been Saved ";
?>

Answer 1

(I) Change your column name in Database table:
1)Seller Mail to Seller_Mail
2)Buyer Mail to Buyer_Mail
3)Product Title to Product_Title
Then insert
$mysqlbuy = "INSERT INTO buyer (Seller_Mail,Buyer_Mail,Bid,Product_Title) VALUES ('$sellmail','$buyermail','$bid','$title')";
Embedded spaces or special characters are NOT ALLOWED in column name.

OR
(II)
If, you don't want to put underscore in column name or don't want to modify your column name. Use like this. (Use Backtick to enclose column name.). But, make sure you follow naming conventions of column name.
$mysqlbuy = "INSERT INTO buyer (`Seller Mail`,`Buyer Mail`,`Bid`,`Product Title`) VALUES ('$sellmail','$buyermail','$bid','$title')";
