Hi all

we use a cms called newscoop - very good but im struggling with what i thought would be a simple emaill form with recaptcha

i have the form sorted in PHP in a folder called contact_form

now in the tpl file i used to use - <?php include('contact_form/form.php'); ?>

obviously cannot do that now

i have read on here about creating a plug in which i tried but cannot get it to show at all

file function.emailplugin.php

<?php
function smarty_function_emailplugin(array $params, Smarty_Template_Instance) {
include 'contact_form/form.php';
}
?>

and in the template have {emailplugin}

any ideas what i am doing wrong

I would take a completely different approach. You are defeating Smarty's fundamental purpose when you include a PHP file from within a template.

The first step to take is to move all of your markup (HTML) from form.php into the Smarty template file. form.php should contain your PHP logic only.

Because I'm a nice guy, I've taken the time to put together a brief example of the PHP logic file (this uses re-CAPTCHA):

Code:

<?php

//This script assumes that the Smarty library is already loaded and that an instance
//of the Smarty object is assigned to $smarty.

session_start();

if (!isset($_SESSION['misc']['captchaPassed']) || $_SESSION['misc']['captchaPassed'] !== TRUE) {
   require('recaptcha-php-1.11/recaptchalib.php');
   
   $captchaHtml = recaptcha_get_html(RECAPTCHA_PUBLIC_KEY, NULL, TRUE);
   
   $smarty->assign('captchaHtml', $captchaHtml);
}

if (!empty($_POST) {
   if (!isset($_SESSION['misc']['captchaPassed']) || $_SESSION['misc']['captchaPassed'] !== TRUE) {
      if (isset($_POST['recaptcha_challenge_field']) && isset($_POST['recaptcha_response_field'])) {
         $resp = recaptcha_check_answer(RECAPTCHA_PRIVATE_KEY, $_SERVER['REMOTE_ADDR'], $_POST['recaptcha_challenge_field'], $_POST['recaptcha_response_field']);
         
         if (!$resp->is_valid) {
            $areErrors = TRUE;
            $errorCaptcha = 'Incorrect letters entered. Please try this new puzzle.';
            $app->smarty->assign('errorCaptcha', $errorCaptcha);
         }
         else {
            //Set this persistant flag so that users aren't asked
            //to complete the CAPTCHA more than once per browser session.
            
            $_SESSION['misc']['captchaPassed'] = TRUE;
            
            //This is necessary to prevent the CAPTCHA from being displayed
            //when it was solved successfully but other validation errors
            //occurred.
            
            unset($app->smarty->tpl_vars['captchaHtml']);
         }
      }
   }
}

$smarty->display('form.tpl');


Then, the template file (form.tpl) might look something like this:

Code:

<form name="create-account" method="post" action="{$smarty.server.REQUEST_URI}">

{if !empty({$captchaHtml})}
   <div>
      <script type="text/javascript">
         var RecaptchaOptions = {
            theme : 'white'
         };
      </script>
      {if !empty($errorCaptcha)}<div class="formError">{$errorCaptcha}</div>{/if}
      <div>{$captchaHtml}</div>
   </div>
{/if}

<input name="btnSubmit" type="submit" value="Create Account" />

</form>
