Need Help Understanding javascript_validation

[webomat]

Hello,

Background: I have Virtual Check service thru Linkpoint -- it's a manual thing, you have to go to their POS site and input the check info to get it approved. So the OSC eCheck thing that was modified and put here back in Aug 06 (I think) works fine for this purpose.

In fact, I've been using it without problem. It's just that some functionality is missing --> validating the input fields. [Using 1.3.6, no mods/contribs re pymt except Linkpoint, which comes with ZC.]

I've been trying to update the eCheck contribution to validate the input fields via the "javascript_validation" section of the module. In doing this, I've been using the Linkpoint module and the standard cc.php as a guide.

I can get it all coded in so that it is valid, but it doesn't trigger the JS Error window. Even stranger, once I upload that revised module the javascript_validation section in the Linkpoint module no longer works! (The php messageStack stuff still works tho.) As soon as I put back the echeck module without the validation section, the Linkpoint js validation works again.

I can see by comparing the eCheck thing that the author used the cc.php file as a base, put in the echeck stuff and returned false on sections not being used for echeck. I've also compared it to the Linkpoint module and they are basically the same, for all intents and purposes. So A = B = C.

So I must be missing something somewhere or I don't understand how it works. Probably both. "-)

I understand the eCheck contribution is not a part of the ZC base, but I'd sure appreciate some help in understanding how to get the javascript_validation section working.

Thanks!

Becky

[For anyone who sees this searching for 'echeck', once I get this working I'll make it available for other Linkpoint users who have that service (or anyone else who just wants to get the details in email for use with their own provider).]

this part is pretty crucial, or else it'll not get triggered for the right module:

 $js = '  if (payment_value == "' . $this->code . '") {' . "\n" .

Hi DrByte,

Thank you for looking at this. Yep, I do have that...

    function javascript_validation() {
    $js = '  if (payment_value == "' . $this->code . '") {' . "\n" .

Basically I took the javascript_validation section from cc.php and linkpoint_api.php as examples and changed the "contents" to match the fields I need validated.

I look at the page source generated and the script is all there. One block for each payment method -- linkpoint_api (from memory) and echeck. The fields for the form are all named correctly and have values. The script seems to have generated properly, I'm not getting any JS errors thrown at me in the browser. It just doesn't work if they are both there. I don't feel 100% with JS and I can't figure out from reading the JS if there is some reason for this not liking two payment methods.

Outside of that section of the file in modules/payment, is there any other section in that file that is critical? I do have the function get_error near the bottom, as in cc.php.

It's not a large file -- it really only collects the info and emails it on. If you have the time and would be willing, I could send it to you or copy here any sections you'd want to see. Or you can get it from the downloads section (echeck) to see what other sections are being returned as false; all I did was add the validation section.

Thanks again for looking,

Becky
