How to pick up object in php

Question

Good evening, everyone,

I’m trying to pass parameters from my controller to php that searches the database and I’m not getting it. I’m passing the data as json object.

controller:

var buscaCategorias = function(){

    var idempresa = $window.localStorage.getItem('idemp');
    var opcao = 'pegarCategoria';
    var buscaCat = {
        "opcao": opcao, 
        "idempresa": idempresa
    };

    console.log(buscaCat);

    $http.post('http://localhost:8888/sistemas/webApps/fluxo_de_caixa/fluxojoin_2.0/php/buscaCatSubcat.php', buscaCat).success(function(data){
        console.log(data);
    });
};

buscaCategorias();

In this console.log(buscaCat), what it shows is Object {option: "pegarCategoria", idempresa: "3"}

PHP:

<?php
ini_set('display_errors', true);
error_reporting(E_ALL);

include_once("con.php");

$pdo = conectar();

$data = file_get_contents("php://input");
$data = json_decode($data);

$opcao = $data->opcao;

switch ($opcao) {
    case 'pegarCategoria':

        $idempresa = $data->idempresa;

        $buscaCategoria=$pdo->prepare("SELECT categoria, idcategoria FROM categoria WHERE empresa_idempresa=:idempresa ");
        $buscaCategoria->bindValue("idempresa", $idempresa);
        $buscaCategoria->execute();

        $return = array();

        while ($linhaCat=$buscaCategoria->fetch(PDO::FETCH_ASSOC)) {

            $linhaCat['categoria'] = $linhaCat['categoria'];
            $linhaCat['idcategoria'] = $linhaCat['idcategoria'];
            $return = $linhaCat;

        }

        echo json_encode($return);

        break;

You got some problems there.

First, the verb GET has no body, data must be passed to the URL via querystring.

So much so that if you open the documentation of $http.get will realize that the second parameter is an object of configuration and not the data you want to pass to the server side. The documentation says:

config | Object | Optional Configuration Object

Only knowing this you will already need to change some things (in the application and also rethink what you are doing).

But there’s also another little problem on the PHP side.

file_get_contents("php://input"); serves to obtain the data received by POST and not by GET.

Possibly only change the GET request to POST will show results.

$http.post('http://urlEnormeAqui/buscaCatSubcat.php', buscaCat).success(function(){ });
