</form>
Here i am not getting how to store it in that table. Actually all the 24 inputs are not mandatory. If user fills only 2 then also it should store it in the database table.
I tried to do like this
if(isset($_POST['save']))
{
$roll_no = $_POST['roll_no'];
$ins_amt1 = $_POST['installment1'];
$due_date1 = $_POST['due_date1'];
$ins_amt2 = $_POST['installment2'];
$due_date2 = $_POST['due_date2'];
$ins_amt3 = $_POST['installment3'];
$due_date3 = $_POST['due_date3'];
$ins_amt4 = $_POST['installment4'];
$due_date4 = $_POST['due_date4'];
$ins_amt5 = $_POST['installment5'];
$due_date5 = $_POST['due_date5'];
$ins_amt6 = $_POST['installment6'];
$due_date6 = $_POST['due_date6'];
$ins_amt7 = $_POST['installment7'];
$due_date7 = $_POST['due_date7'];
$ins_amt8 = $_POST['installment8'];
$due_date8 = $_POST['due_date8'];
$ins_amt9 = $_POST['installment9'];
$due_date9 = $_POST['due_date9'];
$ins_amt10 = $_POST['installment10'];
$due_date10 = $_POST['due_date10'];
$ins_amt11 = $_POST['installment11'];
$due_date11 = $_POST['due_date11'];
$ins_amt12 = $_POST['installment12'];
$due_date12 = $_POST['due_date12'];
$ins_amt13 = $_POST['installment13'];
$due_date13 = $_POST['due_date13'];
$ins_amt14 = $_POST['installment14'];
$due_date14 = $_POST['due_date14'];
$ins_amt15 = $_POST['installment15'];
$due_date15 = $_POST['due_date15'];
$ins_amt16 = $_POST['installment16'];
$due_date16 = $_POST['due_date16'];
$ins_amt17 = $_POST['installment17'];
$due_date17 = $_POST['due_date17'];
$ins_amt18 = $_POST['installment18'];
$due_date18 = $_POST['due_date18'];
$ins_amt19 = $_POST['installment19'];
$due_date19 = $_POST['due_date19'];
$ins_amt20 = $_POST['installment20'];
$due_date20 = $_POST['due_date20'];
$ins_amt21 = $_POST['installment21'];
$due_date21 = $_POST['due_date21'];
$ins_amt22 = $_POST['installment22'];
$due_date22 = $_POST['due_date22'];
$ins_amt23 = $_POST['installment23'];
$due_date23 = $_POST['due_date23'];
$ins_amt24 = $_POST['installment24'];
$due_date24 = $_POST['due_date24'];
$items = array();
$installment[] =array($ins_amt1, $ins_amt2, $ins_amt3, $ins_amt4, $ins_amt5, $ins_amt6, $ins_amt7, $ins_amt8, $ins_amt9, $ins_amt10, $ins_amt11, $ins_amt12, $ins_amt13, $ins_amt14, $ins_amt15, $ins_amt16, $ins_amt17, $ins_amt18, $ins_amt19, $ins_amt20, $ins_amt21, $ins_amt22, $ins_amt23, $ins_amt24);
//$in_values= serialize($installment);
$due_date[] = array($due_date1, $due_date2, $due_date3, $due_date4, $due_date5, $due_date6, $due_date7, $due_date8, $due_date9, $due_date10, $due_date11, $due_date12, $due_date13, $due_date14, $due_date15, $due_date16, $due_date17, $due_date18, $due_date19, $due_date20, $due_date21, $due_date22, $due_date23, $due_date24);
//$in_dates= serialize($due_date);
//$s1 = "insert into installment(id, fee_id, student_id, amount, due_date, paid_date, status, rec_no) values ('', ".$fee_id.", '".$roll_no."', ".$in_values.", '".$in_dates."', '', 'unpaid', ''";
foreach($installment as $row_key => $value)
{
$item = $value;
$uom = $due_date[$row_key];
$items[] = sprintf("(%d, %d, '%s', %d, '%s', '%s', '%s', '%s')", '',
$fee_id,
mysql_real_escape_string($roll_no),
intval($item),
$uom,
'',
'',
''
);
}
$msql = 'INSERT INTO installment (id, fee_id, student_id, amount, due_date, paid_date, status, rec_no) VALUES '.implode(', ', $items);
But it is taking only one data. Can somebody please suggest.
The data has to be saved like this:

Answer 1

A normal INSERT statement should look like:
INSERT INTO table_name (column1,column2,column3,...)
VALUES (value1,value2,value3,...);
So try changing
$msql = 'INSERT INTO installment (id, fee_id, student_id, amount, due_date, paid_date, status, rec_no) VALUES '.implode(', ', $items);
To:
$values = implode(', ', $items);
$msql = 'INSERT INTO installment (id, fee_id, student_id, amount, due_date, paid_date, status, rec_no) VALUES ('.$values.');
And don't forget to actually run the sql command. I don't see that in your script anywhere :)
