Adding Field to Checkout

[BackSpacer]

OK, I finally got what I needed by modifying another module. I used the order delivery date mod and basically duplicated it four times and changed the text to what I need. I works perfect in the front end, back end, mysql db, emails, basically everywhere. The only problem I have or I should say, the only other thing I need help is to make the four fields I added to be required. They are on the checkout_shipping section of the checkout. A simple javascript validation would be oK, but I just can't figure it out. can someone help me? my test site is at www.meandmomrentals.com/cart if you want to register and do a sample checkout to see the page.

Hi Gang -

Before I start cutting an pasting code, is this mod adding a field to the checkout page that will be added to the totals?

Also - will it work with Zen Cart v1.3.7.1?

Thanks!

This Thread has been extremely helpful, I have found a lot of threads asking the same questions but all have been abandoned or found work a rounds.

Anyway, I have followed through the instructions and got it to work as it should, I do have a couple of questions though.

1) The new fields created, are they secure from sql injection and the like ?

2) How can I make some of the fields required ?

Thanks in advance

1 - depends on how you handle your own data. You need to ensure that it is handled in the same way as all other data being passed. So if it is added to an array, and tehn passed to a zen_db_perform() function this handles the injection checking. If you are creating the insert, then you need to ensure you use zen_db_prepare_input() or similar, however, this function can only be RUN ONCE one your data, oterhwise you will create more problems than you solve!

2 - Making fields required is handled by the checkout page header_php.php file. If you are submitted the shipping page, it would be within includes/modules/pages/checkout_shipping/header_php.php. Chek that the data is set correctly, and if not, raise the error. You'll see similar examples within this file.

Thanks for the prompt reply.

Im using the exact example given in the 2nd post in this thread, just repeating the process for the amount of feilds I need (changing there names of course)

so in includes/modules/pages/checkout_shipping/header_php.php

this line

if (zen_not_null($_POST['frequent_code'])) {
$_SESSION['frequent_code'] = zen_db_prepare_input($_POST['frequent_code']);
}
$frequent_code = $_SESSION['frequent_code']; 

Im assuming takes care of it

Once again, thanks for the help and prompt reply

That will handle SQL injection for you as it includes the zen_db_prepare_input() function.

Ive been wracking my brain for a few hours now on how to make a radio button group

I found

function zen_draw_radio_field($name, $value = '', $checked = false, $parameters = '') {
    return zen_draw_selection_field($name, 'radio', $value, $checked, $parameters);
  } 

in includes/functions/html_output.php and I can get it to show a button on the page if i declair $name, $value, but i have no idea what $parameters should be.

Obviously I have more than one set of options and values so im at a loss on how to get my options and values output onto the page.

Any help or pointers to some example code is much apreciated

Thanks in advance

Parameters is a catch-all for anything else you need e.g. 'class="myRadioButton"'. You don't have to put anything in there if you don't need anything.

You would use this function once of each option/value combination, grouping the options by giving them the same name, with each value for that option having its own unique value.

You'll probably want to sprinkle lightly with LABEL tags too.
