Symfony implements the method for obtaining the request parameter in the behavior and template, symfonyrequest

This example describes how to obtain the request parameter in the Symfony implementation behavior and template. We will share this with you for your reference. The details are as follows:

1. Obtain parameters in the template

<?php echo $sf_request->getParameter('name','namespace');?><?php echo $sf_request->getParameter('name');?>

2. Get parameters in the action

$ Request-> getParameter ('name'); // obtain parameters in the template <? Php echo $ sf_params-> get ('name')?> // Parameters with default values <? Php echo $ sf_params-> get ('name', 'default')?> // Determine whether a parameter exists in the template <? Php if ($ sf_params-> has ('name'):?> <P> Hello, <? Php echo $ sf_params-> get ('name')?>! </P> <? Php else:?> <P> Hello, JohnDoe! </P> <? Php endif;?> // Array containing all parameters $ request-> getParameterHolder ()-> getAll () // complete URI path // 'HTTP: // localhost/myapp_dev.php/mymodule/myaction 'geturi () // '/mymodule/myaction' getPathInfo () // $ hasFoo = $ this-> getRequest () in the action () -> hasParameter ('foo'); $ hasFoo = $ this-> hasRequestParameter ('foo'); // Shorter version $ foo = $ this-> getRequest () -> getParameter ('foo'); $ foo = $ this-> getRequestParameter ('foo'); // Shorterversion
