make sure that this query
$p1= mysqli_query($con, "select * from mcq_user where test_id=$tid and sess_id=$username");
will return a record which consists of atleast 8 column...
one more thing
if $username is a string than you should use single quote around it
$p1= mysqli_query($con, "select * from mcq_user where test_id=$tid and sess_id='$username'");

I get proper output on movies.php which is the first 3 rows from database,but when i click on the dynamically created pagination link like movies.php?page=2 then there is no output on this page.This code works fine if i manually set the
$_SESSION["lang1"]="English"; then i get proper output but when i take input from the form it doesnt work.
I want to add loop to my sql query so that all the data from the table gets updated at one click. Right now only the last row is getting updated.

i want to check if the trueans is greater than 15 it should insert pass if not fail in the grade value

('$login',$tid,grade,$_SESSION[trueans])")
Thanks I have finally get solution to my question this what my code now look like mysql_query("insert into ats_result(login,test_id,score,grade)values('$login','$tid',$_SESSION[trueans],IF($_SESSION[trueans]>=10,'Pass','Fail')"); thanks all for the response and challenges throw to me.

I want to store date to database from jquery datepicker. above is my code and error is Warning: strtotime() expects parameter 1 to be string, array given. Can i store date to database as array.Plz help.
Change Input name to :-
echo "<td>".'<input type="text" name="date_from" class="datepicker">'."</td>"; // remove []
echo "<td>".'<input type="text" name="date_to" class="datepicker">'."</td>"; // remove []
Use Dateformat like this
Try: date("Y-m-d") which uses the numeric equivalents.
