I once again here. Come on.

Well, here’s my problem:

I am passing values to my method in php via ajax, however they are not returning me anything, I did some tests and it is catching on the following line

I will post the test code (where it gives me back) and what I want but is crashing

PHP method

public function listarCidade($id)
{
    $obj_cidade = $this->verTodos("est_id=$id");
    if( $obj_cidade )
    {
        $opt="";
        foreach ($obj_cidade as $key)
            $opt .= "<option value='{$key->id}'>{$key->cid_nome}</option>";

        echo json_encode($opt);
    }
}

In this line:

$opt .= "<option value='{$key->id}'>{$key->cid_nome}</option>";

 -O problema está sendo apenas isso ( `$key->cid_nome` )

because if I remove this little code it gives me the return but without anything written in

<option></option>

What to do in people ?

    json is to return array, your code is creating a string, so just give echo $opt and should work. Now if you’re retouching something else, you have to post the ajax request code and also the html page data that it’s picking up.

  • HAHAHAHAHHA, solved friend!

  • I changed my return to html, for being a simple string the return, I did not know that had this conflict because it always works like this. I will pay more attention, an experience more acquired today. THANK YOU!
