how can i know if the mysqli worked or not ? is there an error reporting function?

$f = "INSERT INTO poll3 (op1,op2,op3,op4,op5,subject,gen) VALUES ($op1,$op2,$op3,$op4,$op5,$subject,$gen)";
include 'cpoll.php';
mysqli_query($link,$f);

i am doing this and nothing happens so is there any function to get the error'?

you can capture the result of mysql_query
$result = $mysql_query(...)
IF there is a problem, it returns FALSE and you can use mysql_error ($link) to get the text

Are you sure the session is open ?
Try with this
$link1 = mysqli_connect("localhost" , "root", "232323113" , "poll");
if ( $link1 )
{
$f = "INSERT INTO poll3 (op1,op2,op3,op4,op5,subject,gen) VALUES ($op1,$op2,$op3,$op4,$op5,$subject,$gen)";
 $result = mysqli_query($link1,$f);
if ($result == FALSE )
echo mysql_error($link1);
}
else
{
echo mysql_error($link1);
}

Try my upper solution or this:

mysqli_* functions are deprecated, use mysql_* instead.
$link1 = mysql_connect("localhost" , "root", "232323113" , "poll");
 
$f = "INSERT INTO poll3 (op1,op2,op3,op4,op5,subject,gen) VALUES ($op1,$op2,$op3,$op4,$op5,$subject,$gen)";
 
$result = mysql_query($link1,$f) or die(mysql_error());
echo $result;
