Check your Name assigned in the HTML page relevent to $_POST in PHP.
For Example:
$room_status =$_POST['room_status'];
There are no fields in HTML page.

You forgot the some fields in your insert query sno,pcode,geo & rent ,your post should be:
$room_status =$_POST['status'];
$room_for =$_POST['rent_for'];
$beds_status =$_POST['bed'];
$study_table =$_POST['s_table'];
query:
$sql = "INSERT INTO `user_record`(`sno`,`fsname`,`lsname` , `rent_on`,`room_status`,`city`,`area`,`college`,`room_for`,`quantity`,`beds_status`,`study_table`,`wifi`,`gizer`,`contact`,`password`,`mail_id`,`address`,`pcode`,`geo`,`rent`) VALUES (NULL,'$fsname','$lsname','$rent_on','$room_status','$city','$area','$college','$room_for','$quantity','$beds_status','$study_table','$wifi','$gizer','$contact','$password','$mail_id','$address','$pcode','$geo','rent')";
You code is open to sql injection ,use prepared statements, sanitize your variables,don't forget to secure your password

- Your sql is vulnerable; please convert your queries to prepared and include security measures.
- you're missing the pcode column in your query. When you don't include a column ie (
INSERT INTO tbl (col1,col2) VALUES ('col1','col2');) But, your table has a col3 and the table is set up ascreate table tbl (col1 id not null auto_increment, col2 varchar(5), col3 boolean). When you insert in your current query, the SQL is left assuming that you have a default value in pcode(col3) because you declined to supply it in the column declarations.

You can try insert statement like and check values against each variable easily
$sql = "INSERT INTO `user_record` SET
`fsname` = '".$fsname."',
`lsname` = '".$lsname."',
`rent_on` = '".$rent_on."'........
