Question

I’m trying to create a function where a user should select an option from a <select> and add a date to the value selected (inside <input type='text'> on the same row). Then when the fields have been inputted send as an array to a PHP file and inserted to a database.

I’m creating the <select>, and <input type='text'> dynamically on the same row in a table.

Selects look something like this: <input type='select' class='add_absence_type'>
Input fields: <input type='text' class='add_absence_date'>

The script I’m working on looks like this at the moment:

$('#save').click(function() {
function serealizeSelects (select)
    {
        var array = [];
        select.each(function(){ array.push($(this).val()) });
        return array;
    }
function serealizeInputs (input)
    {
        var array = [];
        input.each(function(){ array.push($(this).val()) });
        return array;
    }
    var student_id = $('#student_id').val();
    var add_absence_type = serealizeSelects($('.add_absence_type'));
    var add_absence_date = serealizeInputs($('.add_absence_date'));

    $.post('../updateAbsence.php', {

    student_id: student_id,
    add_absence_type: add_absence_type,
    add_absence_date: add_absence_date

    }, function(data) {
        location.reload();
    });
});

The $_POST data looks like this:

student_id  1
add_absence_date[]  2012-11-13
add_absence_date[]  2012-11-14
add_absence_type[]  1
add_absence_type[]  2

What do I need to do to create a PHP loop that creates mysql_query‘s like this? See below:

"INSERT INTO my_table (student_id, absence_type_id, absence_date) VALUES ('1', '1', '2012-11-13')"

"INSERT INTO my_table (student_id, absence_type_id, absence_date) VALUES ('1', '2', '2012-11-14')"

Try this way

<?php
$student_id = $_POST['student_id'] ;
$absence_date_arr = $_POST['add_absence_date'] ;
$absence_type = $_POST['add_absence_type'] ;

foreach($absence_date_arr as $key=> $absence_date){
    mysql_query("INSERT INTO my_table (student_id, absence_type_id, absence_date) VALUES ('".$student_id."', '".$absence_type[$key]."', '".$absence_date."')");  
}
?>
