How can i add data into a json file?

[duranmla]

Hi Sencha Community,

I need to know how i can add more data to my json file, i have my model 'clasificacion' , store 'clasificacion' and 'clasificacion.json' this files look like this:

STORE:

Ext.define('myMoney.store.Clasificacion',{	extend: 'Ext.data.Store',
	
	config: {
		model: 'myMoney.model.TipoPago',
		autoLoad: true,
		
		proxy: {
			type: 'ajax',
			url: 'clasificacion.json'
		}
	}
});

MODEL: (i use the same model that another store)

Ext.define('myMoney.model.TipoPago', {    extend: 'Ext.data.Model',
    
    config: {
        fields: [
            {name: 'name', type: 'string'}
        ]
    }
});

and my json file:

[	{
		name: "Comida"
	},
	{
		name: "Transporte"
	},
	{
		name: "Ropa"
	}
]

So.. how i can make that my json file have another data and it will come

[	{
		name: "Comida"
	},
	{
		name: "Transporte"
	},
	{
		name: "Ropa"
	},
        {
                name:"Example"
        }
]

What do you mean add more data? Like change the file?

Yeap, chage the file, i think that i need read all data and make a new file with more data.
How i can do this? Sencha Touch have any method?

var myStore = Ext.getStore('Clasificacion');
myStore.add({name: 'name1'}, {name: 'name2'});

You can't actually change the actual file, the browser simply cannot do it. You would need a server side language to write to the file.

Yes, well this is not a problem, my app need a server conection for store and procesing data, so any suggestions? any tools that you can tell me or method that i should use for do this?

I guess the solution is called PHP!

Actually I am in need to add data to a server based .json file as well but never worked with PHP before.
Therefor it would be really great if someone could post some example code!

http://docs.sencha.com/touch/2-0/#!/...ore-method-add

var myStore = Ext.getStore('Clasificacion');
myStore.add({name: 'name1'}, {name: 'name2'});

This code i think that work for that but is'nt iSmartDevice (Or you do this somtime before?), so is like mitchellsimoens and Kayakkojote say i thnk that i need built a new json file with a server method for that.

As I mentioned in my last post, try to use a .php file to realize that.

You can call it by implementing an Ext.Ajax.Request and use the "params" option to modify the URL which will be sent to the .php file.

Within that .php file use sth like:

$testvar = $_GET['varnameFromURL'] 

to get the param out of your URL.
After that open your .json file with the php methods (json_decode / json_encode) modify it and save it.

Have a look at:

That website helped me a lot!
