Joomla Messages

I have set up a ChronoForm to replace Joomla's default registration form. All work fine apart from that after a form is submitted the next page displays both my Thank You message and Jooma's default message (You can now log in).

I am using the following php code as onSubmit Code - after sending email:

<?php
global $mainframe;

$custom_tag = '<meta http-equiv="refresh" content="5; url=http://www.mysite.gr" >';
$mainframe->addCustomHeadTag($custom_tag);
?>
<p>Thank you for your registration</p>

Although I have tried to disable the 'Show Joomla messages' in the Joomla Registration plugin, it doesn't save my choice. Every time I open the plugin's configuration tab the Joomla messages are enabled.
Thank you for your help and time.

Hi dimitris02,

Oops, there is quite a severe bug in the Plug-ins Helper file which means that paramters with default values set to 1 will never save with a value of 0 :-(

Please open administrator/components/com_chronocontact/helpers/plugin.php and look for this code around line 70 and comment out (or delete) the two marked lines:

        $params = JRequest::getVar( 'params', '', 'post', 'array', array(0) );
       // $mainframe->enqueuemessage(print_r($params, true));
        if ( is_array( $params ) ) {
            $txt = array();
            foreach ( $params as $k => $v ) {
                if ( is_array($v) ) {
                    $v = implode('|', $v);
                }
                // if ( $v ) {  <-- comment out this line
                    $txt[] = "$k=$v";
                // } <-- comment out this line
            }
            $row->params = implode( "\n", $txt );
        }

Apologies.

Bob
