Can validate fields using space

Hi. I have two questions, perhaps someone can help me with.

[1] When I validate a text field and preview it in my internet browser, I can just hit space on any text or number field and it validates. Is there a way I can set it so that you can't use just spaces to validate a field?

[2] Im designing an order form to sell physical goods e.g. paper weights that light up.
The form will have 2 products (different sizes), each product will have a quantity field
and a total value will be displayed when a user presses the submit button. Please can someone help me to design this using css form builder?

Thanks.

Make sure to check the Required Attribute. If you do not select the required attribute for the form field, you will be able to enter a space.


Are you saying you want to get the total of the two quantity fields? If so you can do simple math on the values entered.

for this example, the quantity form elements are named qty1 and qty2

<?php

if((isset($_POST['qty1']) && is_numeric($_POST['qty1'])) && (isset($_POST['qty2']) && is_numeric($_POST['qty2']))) {

    $totalQTY = $_POST['qty1'] + $_POST['qty2']

    echo(totalQTY);        

}

?>

Thanks Jason.

Please could you tell me how I can check the required attribute. All i want to do is to stop people adding only a space in the form field to validate it. So you can type words and spaces but not just a space to validate a field.

Please help.

When Creating the form in Form Builder, click the Edit Button Next to the Forms name, In the edit Form Contents screen, select the group that contains the form element you wish to edit, the click the edit button.

Select the Form Element in the list, then check the required box in the validation section.
