What about something like this? --- <?php /* $Id$ */ /* * Smarty plugin * ------------------------------------------------------------- * File: compiler.object.php * Type: compiler * Name: object * Purpose: generate code that calls an object-method with * additional params * Limitations: methods have to be defined as * method(array $params, object &$smarty) * just like plugin-functions * Example: {object $myobj->get_header foo=$foo bar="bar"} * ------------------------------------------------------------- */ function smarty_compiler_object($tag_arg, &$smarty) { list($call_str, $params_str) = split(' ', $tag_arg, 2); if (isset($params_str)) { $params = ''; foreach ($smarty->_parse_attrs($params_str) as $key=>$value) { if (strlen($params)>0) $params .= ', '; $params .= '"'.$key.'"=>'.$value; } } if (preg_match('[(.*)->(.*)]', $call_str, $match)) { $code = $smarty->_parse_var($match[1]).'->'.$match[2].'('; $code .= 'array('.$params.'), $this);'; } return $code; } /* * Local variables: * c-indentation-style: bsd * c-basic-offset: 3 * indent-tabs-mode: nil * End: * * vim: expandtab shiftwidth=3: */ ?> --- it is just a test and needs robust error-handling. and okay, you cannot call arbitrary methods, but this could be done with slight modifications. i don't think it would be right to do this, since it gives a little bit too much power to the template and makes it very easy to wire application-logic into the template. but that is just my opinion btw: merry christmas to everybody on the list, and thank you for such a great tool smarty is. i love to use it for private purposes and at work. go on with it ! :) messju > Monte > > > -- > Monte Ohrt <monte@ispi.net>
