将Store中的值传递给PHP

Question

我试图将值传递给PHP服务器端。我的商店代码如下;

Ext.define('MyApp.store.MyArrayStore', { 
    extend: 'Ext.data.Store', 

    requires: [ 
     'MyApp.model.MyMOD' 
    ], 

    config: { 
     autoLoad: true, 
     model: 'MyApp.model.MyMOD', 
     storeId: 'MyArrayStore', 
     proxy: { 
      type: 'ajax', 
      actionMethods: 'POST', 
      url: 'http://localhost/mm/app/php/res.php', 
      reader: { 
       type: 'json' 
      } 
     }, 
     listeners: [ 
      { 
       fn: 'onArraystoreBeforeLoad', 
       event: 'beforeload' 
      } 
     ] 
    }, 

    onArraystoreBeforeLoad: function(store, operation, eOpts) { 
     this.proxy.extraParams.VALUES1 = "pass some name here"; 
    } 

}); 

PHP代码

<?php 
error_reporting(E_ERROR | E_PARSE); 

require_once 'conn.php'; // contains the connection 

$v = $_POST['VALUES1']; 
echo json_encode($v); 

?> 

获取返回什么是null，而不是说我从店里传递（这是pass some name here）的值。

我该如何纠正？

Answer 1

而不是this.proxy尝试this.getProxy()。

我发现控制台对这类事情非常有用。在我自己的应用程序运行Ext.getStore('MyStore').proxy;让我undefined而Ext.getStore('MyStore').getProxy()让我的代理。

使用控制台，对我来说它是接下来API最有价值的开发工具。

祝你好运，布拉德

Answer 2

您需要更改设置extraParams的方式。在这种情况下，我会使用

store.getProxy().setExtraParam('VALUES1','pass some name here'); 

如果您需要发送一个以上的参数，然后使用setExtraParams

var param = { VALUES1: 'param1', VALUES2 : 'param2'}; 
    store.getProxy().setExtraParams(param); 

如此充满店内码

Ext.define('MyApp.store.MyArrayStore', { 
    extend: 'Ext.data.Store', 

    requires: [ 
     'MyApp.model.MyMOD' 
    ], 

    config: { 
     autoLoad: true, 
     model: 'MyApp.model.MyMOD', 
     storeId: 'MyArrayStore', 
     proxy: { 
      type: 'ajax', 
      actionMethods: 'POST', 
      url: 'http://localhost/mm/app/php/res.php', 
      reader: { 
       type: 'json' 
      } 
     }, 
     listeners: [ 
      { 
       fn: 'onArraystoreBeforeLoad', 
       event: 'beforeload' 
      } 
     ] 
    }, 

    onArraystoreBeforeLoad: function(store, operation, eOpts) { 
     store.getProxy().setExtraParam('VALUES1 ','pass some name here'); 
    } 

});
