I find Joomla non-developer friendly for the most of the time; documentation is poor and not having any continuity.<\/p>\n

I searched the net for displaying errors to the screen in Joomla 1.5 and up and here is the code:<\/p>\n

JError::raiseWarning(‘101’, “message to be displayed”);<\/p>\n

This bunch of code is especially useful if you are developing extended classes for Joomla, such that if you are developing a authentication plugin for Joomla:<\/p>\n

<?php<\/p>\n

defined(‘_JEXEC’) or die();<\/p>\n

jimport(‘joomla.event.plugin’);<\/p>\n

\/\/ class plg<type><name> extends JPlugin
\nclass plgAuthenticationMSN extends JPlugin
\n{
\nfunction plgAuthenticationMSN(& $subject, $config) {
\nparent::__construct($subject, $config);
\n}<\/p>\n

function onAuthenticate( $credentials, $options, &$response )
\n{<\/p>\n

$err = “IP:”.$remoteCpIP.” port:”.$port;
\nJError::raiseWarning(‘101’, $err);<\/p>\n

if ($success)
\n{
\n$response->status\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 = JAUTHENTICATE_STATUS_SUCCESS;
\n$response->error_message = $err;
\n$response->email\u00a0\u00a0\u00a0\u00a0 = $email;
\n$response->fullname = $credentials[‘username’];
\n}<\/p>\n

else
\n{
\n$response->status\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 = JAUTHENTICATE_STATUS_FAILURE;
\n$response->error_message\u00a0\u00a0\u00a0 = ‘Failed to authenticate: ‘ . $message;
\n}
\n}
\n}
\n?><\/p><\/blockquote>\n

This is\u00a0 the only way to see the errors on the screen,”echo” and other stuff doesn’t show anything as you are inside a class.<\/p>\n","protected":false},"excerpt":{"rendered":"
