To simply get a GET or POST variable from an HTTP request, you use the following code:
// Get a variable from GET $getVar = $this->params()->fromQuery('var_name', 'default_val'); // Get a variable from POST $postVar = $this->params()->fromPost('var_name', 'default_val');
In the example above, we used the
Params controller plugin, which provides you with
convenient methods of accessing GET and POST variables, uploaded files, etc.
In line 2 we use the
fromQuery() method for retrieving a variable having name "var_name" from GET.
If such a variable does not present, the default value "default_val" is returned.
The default value is very convenient, because you don't have to use the
function to test if the variable exists.
In line 5 we use the
fromPost() method to retrieve the variable from POST. The meaning
of this method's parameters is the same as for the
In ZF3, you must not access request parameters through traditional PHP
$_POSTglobal arrays. Instead, you use ZF3-provided API for retrieving the request data.
