This plugin works similar to namespace templates but the template to use is chosen based on a configuration matching regular expressions against the page name.

Search and install the plugin using the Extension Manager. Refer to Plugins on how to install plugins manually. If installed manually, rename the plugin directory to regextemplate(no underscore).

There is one configuration option to add regex, they must be added one per line, take care of spaces, in the following format:

 pattern,replacement

pattern and replacement MUST follow the preg_replace rules.

 /.*:info:start/,templates:info_start
 /.*:info:.*:issue/,templates:info_issue

You here just have to edit the templates/info_start and templates/info_issue to make them templates (no worry of _template.txt and __template.txt they are used if the regex does not match or if the templates in the regex does not exists.

NS replace does not work, $id needs to be replaced by $ID (line 65 in action.php)

	// replace placeholders
	$tpl = str_replace('@ID@',$ID,$tpl);
	$tpl = str_replace('@NS@',getNS($ID),$tpl);

Otherwise great plugin. Jörg

The plugin does not work with rc2010-10-27 “Busy Wednesday”, for me this works:

  /**
   * register the eventhandlers
   */
  function register(&$contr){
    $contr->register_hook('COMMON_PAGE_FROMTEMPLATE', 'BEFORE', $this, 'regex_template', array());
  }
 
  function regex_template(&$event, $param) {
	global $conf;
 
	$array_regex = (array)explode("\n",$conf['plugin']['regex_template']['reg_tpl_regex']);
	reset($array_regex);
	foreach ($array_regex as $regex) {
	  list($pattern, $replacement) = explode(',', $regex);
	  $my_new_ID = @preg_replace($pattern, $replacement, $event->data['id']);
	  $my_new_file = wikiFN($my_new_ID);
	  if(@file_exists($my_new_file)){
		$tpl = io_readFile($my_new_file);
		break;
	  }
	}
        if($tpl) $event->data['tpl'] = $tpl;
  }
}

(from lahondes at sibio.fr) This work with latest version using the code just above and modifying the hook (which was changed in 2011-02-03), using COMMON_PAGETPL_LOAD instead of COMMON_PAGE_FROMTEMPLATE. This give the following version of action.php:

  /**
   * register the eventhandlers
   */
  function register(&$contr){
    $contr->register_hook('COMMON_PAGETPL_LOAD', 'BEFORE', $this, 'regex_template', array());
  }
 
  function regex_template(&$event, $param) {
	global $conf;
 
	$array_regex = (array)explode("\n",$conf['plugin']['regex_template']['reg_tpl_regex']);
	reset($array_regex);
	foreach ($array_regex as $regex) {
	  list($pattern, $replacement) = explode(',', $regex);
	  $my_new_ID = @preg_replace($pattern, $replacement, $event->data['id']);
	  $my_new_file = wikiFN($my_new_ID);
	  if(@file_exists($my_new_file)){
		$tpl = io_readFile($my_new_file);
		break;
	  }
	}
        if($tpl) $event->data['tpl'] = $tpl;
  }
}
