Page validating (error checking)

[marcopolo]

I modified a page that currently is validating a form entry making sure it is filled in before submitting, works fine HOWEVER I change the action from the following:

<?php echo zen_draw_form('pagename', zen_href_link(FILENAME_PAGENAME, 'action=send', 'SSL')); ?>

to:

<form method="POST" action="/test-page.php" target="popup"> 

which kills the validation and lets the user submit the form with or without filling in the entry.


I narrowed the code that controls this down to the following in the pages header file:

  $error = false;
  if (isset($_GET['action']) && ($_GET['action'] == 'send')) {
    $fieldname1 = zen_db_prepare_input($_POST['fieldname1']); 

Anyone know how to to rewrite the code to make it work again?

Ummm... Change it back?

Otherwise, append the ?action=send parameter to your form's action?

such as:

<form method="POST" action="/test-page.php?action=send" target="popup"> 

Though hopefully you have also echoed the result of: zen_hide_session_id() within the open form and close form since the form's post is not being generated with the zen_draw_form function...

Changing it back does not work because on submitting the form it just goes to another zen cart page whereas what I changed it to goes to external page, which I need it to do.

Good idea:

<form method="POST" action="/test-page.php?action=send" target="popup"> 

tried it, does not work.

Nevermind studying the way the original worked I was able to make it work.

Ahh, okay think I understand the situation a little better, though I think I've commented on how this ought to go previously. So, you want the action page identified in the posted form to either validate the data from the posted form or to receive posted data that has already been validated...

So again, either the post form action posts to itself where if the data passes the validation then the popup window is presented with the posted data, or if the action page is as provided above, then it should provide validation up front before possibly using a similar action=send check as the indcator to perform the validation and if it fails to return to the original page with all of the orignal post data intact. If the page is "external" then there are some other things that may need to be considered with regards to using zc functions... In a way the applicable additional images popup screen may provide some assistance on code examples, though I'm not sure there is much in the way of validation there other than that the image is on the server...

Well, shucks wish I had waited a moment for that other response before typing the above... Ahh well... :)
