Development and Programming
Sorry if this question has been answered a million times, but I looked and didn’t see it.
I had a plugin that worked well in EE 1.6.8, but after I upgraded to EE 2.1.3 and recoded it to match the new examples, I got an error that the tag cannot be processed. So I went back to basics and tried the “memberlist” plugin from the user guide (just copied and pasted) and I get the same error:
Error
The following tag cannot be processed:
{exp:memberlist}
Please check that the ‘memberlist’ module is installed and that ‘memberlist’ is an available method of the moduleIs there something obvious I am missing? The plugin file resides in ./system/expressionengine/third_party/memberlist/pi.memberlist.php and I am calling it in a template with {exp:memberlist}, just as the usage says. The permissions are set to 777 on the file and directories. It shows up in the list of plugins in the CP.
Any help nudging me in the right direction would be greatly appreciated!

The Memberlist Plugin simply outputs a
list of 15 members of your site.
{exp:memberlist}
This is an incredibly simple Plugin.
<?php
$buffer = ob_get_contents();
ob_end_clean();
return $buffer;
}
// END
}
/* End of file pi.memberlist.php */
/* Location: ./system/expressionengine/third_party/memberlist/pi.memberlist.php */
Could you try this?
Change: function __construct() to: function Memberlist()
Perfecto! It worked like a charm.
Thanks, Manuel!
Hello Guys,
::warning – PHP NoOb ahead::
Ran exactly in the same problem.
Looks like using __construct() is throwing an error at me as well (using copy paste from the docs + with a very very simple plugin I wrote)
The following tag cannot be processed: {exp:html_strip} Please check that the ‘html_strip’ module is installed and that ‘html_strip’ is an available method of the module
Changing the constructor method to match the name of the class did the trick!
This seems to be in complete contradiction with the official guidelines for class and method naming. Basically I have a plugin that does not work when coding according to official guidelines and the only way I can get it to work is by doing what is labeled as incorrect in the doc.
Am I doing something wrong? Do I miss something (not a PHP wizard here)? Working with EE v 2.1.3 Build: 20101220 PHP infos tells me that PHP 5.3.2 is running on the server.
Code that works
<?php
$plugin_info = array(
'pi_name' => 'Html_strip',
'pi_version' =>'1.0',
'pi_author' =>'Me',
'pi_author_url' => 'http://www.mysite.com',
'pi_description' => 'Strips HTML tags',
'pi_usage' => Html_strip::usage()
);
if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Html_strip {
var $return_data = "";
public function Html_strip()
{
$this->EE =& get_instance();
$this->return_data = strip_tags($this->EE->TMPL->tagdata);
}
// --------------------------------------------------------------------
/**
* Usage
*
* This function describes how the plugin is used.
*
* @access public
* @return string
*/
// Make sure and use output buffering
function usage()
{
ob_start();
?>
The html_strip plugin strips html from your data. No parameters, no nothing.
{exp:html_strip}
content to strip
{/exp:html_strip}
This is an incredibly simple Plugin.
<?php
$buffer = ob_get_contents();
ob_end_clean();
return $buffer;
}
// END
}
/* End of file pi.html_strip.php */
/* Location: ./system/expressionengine/third_party/plugin_name/pi.html_strip.php */Code that does not work
<?php
$plugin_info = array(
'pi_name' => 'Html_strip',
'pi_version' =>'1.0',
'pi_author' =>'Me',
'pi_author_url' => 'http://www.mysite.com',
'pi_description' => 'Strips HTML tags',
'pi_usage' => Html_strip::usage()
);
if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Html_strip {
var $return_data = "";
function __construct()
{
$this->EE =& get_instance();
$this->return_data = strip_tags($this->EE->TMPL->tagdata);
}
// --------------------------------------------------------------------
/**

*/
// Make sure and use output buffering
function usage()

I also ran into this __constructor() vs class_name() constructor issue when building plugins. Someone at EL should really change the documentation.
This looks to have been reported in the Bug Tracker and has a status (as of today) of “Fixed in next release”.
Fingers crossed.
