Unable to enter data into mysql - php

Question

A php script which is intended to enter data into the database is working selectively. Data for 5th and 10th grade gets in but data for all other grades wont show up. I have checked the if else blocks and the logic is working just fine its executing the inner blocks as it is supposed to just wont enter any data into the database. For grades other than 5th or 10th the 2nd block gets executed and i have already checked that it echos the correct value of stuff it is supposed to enter the database. and using a echo after the sql() query i also found out that its working too, so kind of stuck no idea whats wrong please help.
here is the code, let me know if you guys need the html too
<?php
$roll=$_POST['roll'];
$marks=$_POST['marks'];
$dbase=$_POST['std'];
$sec=$_POST['sec'];
$sec1=$_POST['sec1'];
$expire= time()+60;
if (empty($roll) || empty($marks) || ($dbase==0))
{
echo '<p align="center">You did not enter all data. Please go back and enter them.</p>';
echo '<FORM><p align="center"><INPUT TYPE="button" VALUE="Go Back" onClick="history.go(-1);return true;"></p></FORM>';
die();
}

when i modify the 2nd if block like this
if(($dbase!=5)&&($dbase!=10))
{
$sect=$sec1;
echo "roll- ";
echo $roll;
echo " marks- ";
echo $marks;
echo " std- ";
echo $dbase;
echo " section- ";
echo $sect;
setcookie("tab", $temp, $expire, "/","skc-hs.com");
$host="127.0.0.1"; // Host name
$username="root"; // Mysql username
$password=""; // Mysql password
$db_name="data"; // Database name
$tbl_name=$temp; // Table name
// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
// To protect MySQL injection (more detail about MySQL injection)
$roll = stripslashes($roll);
$marks = stripslashes($marks);
$roll = mysql_real_escape_string($roll);
$marks = mysql_real_escape_string($marks);
$sql="insert into $tbl_name (roll , marks, std, sec) values ('$roll' , '$marks' , '$dbase' '$sect')";
mysql_query($sql);
echo " done";
die();
}
it echos "roll- 12 marks- 454 std- 7 section- B done" when i enter those values in the html form. I dont get it why it won't just enter those values in the database

Answer 1

You have forget to place a comma betwwen $dbase and $sect in query.
Change the query from
$sql="insert into $tbl_name (roll , marks, std, sec)
values ('$roll' , '$marks' , '$dbase' '$sect')";
to
$sql="insert into $tbl_name (roll , marks, std, sec)
values ('$roll' , '$marks' , '$dbase' , '$sect')";

Answer 2

You seem to exit() the script if anything isn't a 10 or a 5 with this code:
if(($dbase!=10)&&($dbase!=5)&&($sec1=="0"))
{
echo '<p align="center">You did not enter all data. Please go back and enter them. 3</p>';
echo '<FORM><p align="center"><INPUT TYPE="button" VALUE="Go Back" onClick="history.go(-1);return true;"></p></FORM>';
die();
}
