How can I get a JSON via URL?

rafaelmakiyama

My doubt is. I have one Isset Function in my PHP file.

I want to select this isset to bring me the data
But i dont know how to do this.

You can't via a URL along since your PHP is specifically checking for a POST parameter. You would need to send a POST request!

Allan, so how do I have to do in my PHP? I didnt understand.

I think what Allan is saying - correct me if I'm wrong is that you need to set the parameter cadastrarEstudante, otherwise the PHP script will never know you need to do something.

You can set the data manually via the data option.

$('#example').dataTable( { "ajax": { "url": "data.json", "contentType": "application/json", "type": "POST", "data": function ( d ) { return JSON.stringify( d ); } } } );
In this way?

rafaelmakiyama

in the "data" function i have to pass the parameter "cadastrar estudante"?

Yes, that's the idea. Although you'd manually set the value like below.

ajax: {
    url: "<insert your URL>",
    data: function (d) {
        return $.extend({}, d, {
            "cadastrarEstudante": <value>
        });
    },
    type: "POST"
},

Spot on I'd say! You could also do:

data: function (d) {
  d.cadastrarEstudante = <value>;
}

which in this context gives the same result.
