how to access post parameters in php? - extjs

Question

I am working in Extjs4 plus yii framework and using MVC structure. I am going to send data from extjs4 to yii framework. I am using post method to send data to server side, but I am not yet succeed to display data in yii framework. When I am using get() method the data accessed to yii framework side easily. Actually I dont want to display data in url so thats why I am using post() method in extjs4.
Here is my some code:
Model file:
Ext.define('Bal.model.sn.UserModel', {
extend: 'Ext.data.Model',
//idproperty:'userId',//fields property first position pk.
fields: ['userId', 'firstName', 'middleName', 'lastName', 'languageId', 'primaryEmail', 'birthDate', 'password', 'securityQuestionId', 'securityQuestionAnswer', 'isMale', 'creationTime', 'ipAddress', 'confirmationCode', 'userStatusId', ]
});
Store file:
Ext.define('Bal.store.sn.UserStore', {
extend: 'Ext.data.Store',
model: 'Bal.model.sn.UserModel',
//autoLoad: true,
proxy: {
type: 'ajax',
api: {
read: 'http://localhost/balaee/Balaee/index.php/SocialNetworking/user/AuthenticateLogin',
create: 'http://localhost/balaee/Balaee/index.php/SocialNetworking/user/AuthenticateLogin',
//update: ,
//destroy: ,
}, //End of api
extraParams: {
hello: 'Inside store',
},
actionMethods: {
create: 'POST',
read: 'POST',
update: 'POST',
destroy: 'POST'
},
reader: {
type: 'json',
//root: ,
//successProperty: ,
}, //End of reader
writer: {
type: 'json',
root: 'records',
}, //End of writer
} //End of proxy
}); //End of store
My controller file some code:
var obj = this.getStore('sn.UserStore');
obj.load({
params: {
hello: 'jitu'
}
});
And here is my yii framework controller file code:
$postData = json_decode(file_get_contents("php://input"), true);
$clientData = $postData['records'];
echo $_POST['hello'];
How can I display this hello parameter in yii framework? Please give some suggestion.

Answer 1

I use something like this. if $_POST['PostDataName'] is empty getPost($name) returns NULL
public function actionFoo()
{
$data = Yii::app()->request->getPost('PostDataName');
}

What error you are getting. Like 400, 404, 500 etc. Also do you have CSRF enabled in your YII app. If not then something like this should do.
public function actioTest()
{
$post = $_POST['hello'];
}
If CSRF is enabled then you have to pass CSRF value with the request as well.
