Error "eval()'d code" when UDT used through a CMSMS Event

Hi all,
I named this topic after an exiting one, available at the following address, but "more than 120 days old" and suggesting to start a new one to get an answer.
http://forum.cmsmadesimple.org/index.php/topic,13267.30.html
I wrote a simple User Defined Tag that is supposed to give me the alias of a modified page. The idea is to develop a bit more and get the script send a notification email when a content is modified, as it is written in the forum post that I mentionned. But as I can't get it working, I simplified to get the single Alias value. Whatever I try (including copy/paste of the examples found in the forum and wiki pages) the error is always the same, as stated a bit later. Here is my code :
Code: Select all
global $gCms;
$manager =& $gCms->GetHierarchyManager();
$thisPage = $gCms->variables['content_id'];
$currentNode = &$manager->sureGetNodeById($thisPage);
$currentContent =& $currentNode->getContent();
$mail_content = 'Alias : '.$currentContent->Alias();
This UDT works fine when included as a normal {udt} in the page content. For example, the "echo" instruction prints the correct $mail_content value, no problem.
It's when the UDT is used by an event, added to the ContentEditPost event, as this page instructs, that ot all goes wrong :
http://wiki.cmsmadesimple.org/index.php/User_Handbook/Admin_Panel/Extensions/Event_Manager
I'm running the actual last version 1.5.3 "Arecibo" on a PHP5/Apache Server and here is the error that I keep getting :
Code: Select all
Call to a member function getContent() on a non-object in [...]\www\lib\classes\class.usertagoperations.inc.php(158) : eval()'d code on line [...]
Could anyone tell me how to use this getContent function in the Event's environnement ? My programmer skills are unfortunately too short for me to see it by myself.
Thank you by advance.

I don't think that you have $gCms->variables['content_id'], this is create in frontend page generator
Look in Event help which params you have and call with $params

Thanks for the reply, alby.
It looks like you're pretty right, $gCms->variables['content_id'] is empty. However, I guess that many values could be reached by $param.
Here is what
var_dump($param) returns :
Code: Select all
array(1) {
["content"]=>
&object(Content)#27 (35) {

I just don't know how to write the right syntax to reach the object(Content)#27 and object(ContentProperties)#28 arrays inside values, and then be able tu use the 'mName', 'content_en', 'Second_Content_Block' data that I need in the end to make run correctly the UDT by the Event.
I'm grumbling to appear so weak
Any suggestion is welcome.

have you tried with:
var_dump($params["content"]->mAlias);

Okay ! $params["content"]->mAlias works fine, that's simply what I missed (stupid me).
Sorry for the loss of time and thank you for the help.
I'll soon post the solution that I now should be able to write by myself, whatever it's worth.
Thanks !

Here is the UDT, now working for me. The error was due to a misunderstanding of mine, cleared through this topic. It came from a bad copy/paste of a line from a similar code dedicated to the News notifications treatment.
I post my final script to close this discussion.
Code: Select all
// sends an email to the $mail_to1 address when a page is modified
// if specified, BCC to $mail_to2
// (needs to be added to the go to the Events Handler page: go to Extensions->Events, edit ContentEditPost, select UDT in the dropdown list, and add it)
//
global $gCms;
$content =& $params['content'];
$editorName = $gCms->variables['username'];
$mail_to1 = "name@domain.ext";
$mail_to2 = "";
$mail_subject = "Page change notification, by : " . $editorName;
$mail_content = '
<p>A content has been modified.</p>
<p>
Edited by : ' . $editorName . '<br />
Title : ' . $content->Name() . '<br />
Page ID : ' . $content->Id() . '<br />
Page Alias : ' . $content->Alias() . '<br />
Page Type : ' . $content->Type(). '<br />
Created on : ' . $content->GetCreationDate().'<br />
Modified on : ' . $content->GetModifiedDate().'<br />
URL : <a href="' . $content->GetURL() . '">' . $content->GetURL() . '</a></p>
<p>Here comes the new content.</p>
<hr />
' . $content->mProperties->mPropertyValues["content_en"]. '
<hr />
' . $content->mProperties->mPropertyValues["Second_Content_Block"];
$cmsmailer =& $gCms->modules['CMSMailer']['object'];
$cmsmailer->AddAddress($mail_to1);
$cmsmailer->AddBCC($mail_to2);
$cmsmailer->SetBody($mail_content);
$cmsmailer->IsHTML(true);
$cmsmailer->SetSubject($mail_subject);
$cmsmailer->Send();
