Add parameters to Ajax proxy

[kortovos]

How do you add parameters to an Ajax store?

I am bypassing the cross domain policy by using a php proxy on my server. I am trying to send a few needed parameters to the php page and I expect the response to be xml.

But how do I send certain parameters to the php page on the server?

  var orderStore = new Ext.data.Store({
            model: 'order',
            url: varxml,
            proxy: {
                type:'ajax',
                id: 'data',
                url: 'proxytest.php',
                method: "POST",
                params:{action: 'askorderlist',
                     question: 'uborderlist',
                     value: '2010-08-01',
                     user: 'username',
                     password: 'password'
                 },
                reader: {
                    type: 'xml',
                    record: 'order'
                }
            },
    autoload: true,
    });

Just append the parameter to the url:

var orderStore = new Ext.data.Store({
            model: 'order',
            url: varxml,
            proxy: {
                type:'ajax',
                id: 'data',
                url: 'proxytest.php?username=dummy&age=' + somevar,
                method: "POST",
                params:{action: 'askorderlist',
                     question: 'uborderlist',
                     value: '2010-08-01',
                     user: 'username',
                     password: 'password'
                 },
                reader: {
                    type: 'xml',
                    record: 'order'
                }
            },
    autoload: true,
    });

Isn't that a 'GET'? And if so, isn't there a limit to the number of characters you can append to the url?

What if I want to use a 'POST'?

[evant]

Ext.setup({
    onReady: function(){
        Ext.regModel('Foo', {
            fields: ['a']    
        });
        
        new Ext.data.Store({
            autoLoad: true,
            model: 'Foo',
            proxy: {
                url: 'data.asp',
                type: 'ajax',
                extraParams: {
                    foo: 'bar'
                }
            }
        });
    }
});

By default all read operations will be a get. You can override it for a single instance by using:

// create store
myStore.proxy.actionMethods.read = 'POST';
myStore.load();

Or globally:

Ext.apply(Ext.data.AjaxProxy.prototype.actionMethods, {
     read: 'POST'
});
// create store

[kortovos]

Thanks Evant for your quick response. In your example the extraParams you pass to the proxy also are present in the model, is this a necessity?

I am still getting errors. Is there a 'success' and 'failure' parameter for stores or readers, like with an Ext.Ajax.request?

No, I just happened to use the same name for the model and the property, they are in no way related.

As for the other one, it sounds like you're sending back malformed data.

[kortovos]

The response should be something like : <?xml version="1.0" encoding="UTF-8"?><orderlist><order><orderid>2005048</orderid></order><order><orderid>3000359</orderid></order><order><orderid>2007062</orderid></order><order><orderid>2007118</orderid></order><order><orderid>3000362</orderid></order><order><orderid>2007134</orderid></order><order><orderid>2007135</orderid></order><order><orderid>2007142</orderid></order><order><orderid>3000367</orderid></order><order><orderid>2007178</orderid></order></orderlist>

Could it be the header (<?xml version="1.0" encoding="UTF-8"?>) that is causing the problem?
With Chrome dev tools, when I click on "http://localhost/proxytest.php?_dc=1285569086510", it displays the correct output.

[kortovos]

And my model is

Ext.regModel('order', {
    fields : [ {
        name : 'orderid',
        type : 'integer'
    }]
}); 

Anyone an idea what I am doing wrong?

[kortovos]

Oke, I made sure that the server returns text/xml, by adding 'header("Content-Type: text/xml");' to the php document. So now I don't get any errors, but the store still doesn't get filled.

How you check if the store is filled?
