Question

I have a database table with some rows that I want to fetch using PHP and then encode them using JSON.

Currently, my database structure is the following:

idcomponente | quantidade

After fetching the values in PHP, I want to know how can I encode them using JSON (with multiple rows, using the same names) so I can read them using jQuery.post().

$.post('test.php',{id:id},function(data){
    //READ data HERE
});

Thanks in advance

Edit:

So far, I made this:

$.post('edit/producomponentes.php',{id:id},function(data){
    console.log(data);
});

Logs this:

[Object { componente="1", quantidade="2"}, Object { componente="3", quantidade="3"}]

Now how can I go through each row and fetch their properties? (data.componente, data.quantidade)

Answer 1

Here I try to give you some idea.

Make associative array in PHP using key => value pair like

$data = array('id' => 1, 'quat' => 10, 'id' => 2, 'quat' => 20)

and then send it as json_encode() like

header('Content-type: application/json');  // don't miss it
echo json_encode(array('data' => $data));

In jQuery

$.post('edit/producomponentes.php',{id:id},function(response){
    //READ data HERE.
    console.log(response.data); // you will get a json Object
}, 'json');
     ^-------- set dataType as json, then you don't any extra parse effort

According to edit

 $.post('edit/producomponentes.php',{id:id},function(data){
        $.each(data, function(index, value) {
           console.log(value.componente);
           console.log(value.quantidade);
        });
    }, 'json');
