I. Getting parameters in a template

<?php echo $sf _request->getparameter (' name ', ' namespace ');? ><?php echo $sf _request->getparameter (' name ');? >

$request->getparameter (' name ');//Template Get Parameters <?php echo $sf _params->get (' name ')? >//with default values <?php echo $SF _params->get (' name ', ' Default ')? >//in the template to determine whether a parameter exists <?php if ($sf _params->has (' name ')):?>
hello,<?php echo $sf _params->get (' name ')? >!
<?php Else:?>
hello,johndoe!
<?php endif; >//contains an array of all parameters $request->getparameterholder ()->getall ()//full URI path//' http://localhost/ Myapp_dev.php/mymodule/myaction ' GetURI ()//'/mymodule/myaction ' getpathinfo ()//in action $hasfoo = $this Getrequest ()->hasparameter (' foo '); $hasFoo = $this->hasrequestparameter (' foo ');//shorter version$foo  =$ This->getrequest ()->getparameter (' foo '); $foo  = $this->getrequestparameter (' foo ');//shorterversion
