Question

I tried to make my textbox type in currency format. I did it, but when I insert the value it into my database the value changes. When I type 10000, it changes 10,000. (So far so good.) But when I insert that value into database the value changes to 10. I’m really confused.

Here is my script. I used php, mysql, and the field type is float

    <?php include('header.php'); ?>
<?php
    if(isset($_POST['simpan']))
    {
        $nama           = htmlentities(addslashes($_POST['nama']));
        $sim_wajib      = $_POST['sim_wajib'];
        $sim_pokok      = $_POST['sim_pokok'];
        $sim_sukarela   = $_POST['sim_sukarela'];
        $sim_wpinjam    = $_POST['sim_wpinjam'];
        $shu            = $_POST['shu'];
        $total          = $sim_wpinjam + $shu;

        if($nama != '' && $sim_wajib != '' && $sim_pokok != '' && $sim_sukarela != '' && $sim_wpinjam != '' && $shu != '' )
        {
            $sql     = "INSERT INTO simpanan_tbl";
            $sql    .= "(nama, sim_wajib, sim_pokok, sim_sukarela, sim_wajibpinjam, shu, jumlah)";
            $sql    .= "VALUES('$nama','$sim_wajib','$sim_pokok','$sim_sukarela','$sim_wpinjam','$shu','$total')";
            $query   = mysql_query($sql) or die(mysql_error());
            echo '<script type="text/javascript">alert("Data telah masuk!");document.location="manage_simpanan.php";</script>';
        }
        else
        {
            echo '<script type="text/javascript">alert("Kolom tidak boleh ada yang kosong!");</script>';
        }
    }
?>

If you have to have accounting style formatting within your text boxes, I would suggest having a hidden field with the raw numeric value alongside each textbox. You could easily add a few lines to the js function right after the “nr = nr.replace(regex,”);” section to copy the now stripped value to the hidden field. To do this, you would have to name each textbox and pass the name to the numberFormat function so that it saves it to the correct hidden input. Then, when the form is submitted, save the values from the hidden fields, not the open textboxes.

Alternately, have your Submit button trigger a function to sweep through all your text fields and remove any formatting, then submit the form as part of the function.

By the way, inserting 10,000 as ten thousand into a float field will trim it to 10. Unless you are using a comma as a decimal point (which I think the French do?) you are saving incorrect data.
