I need a help I have a page on an X server and I need to get another page from the Y server. I tried on ajax and I couldn’t so I had to use the iframe, but I need to pass a parameter to the destination page of the Y server and it is not working?

Below follow the codes:

Source X Server Page

<?php
    error_reporting(0);
    ini_set("display_errors", 0 );
    session_start();

    $perfil = $_SESSION['perfil'];
    echo $perfil;
?>
<br>
<iframe 
    style="border: 0;"
    src="https://172.20.220.50/webservice/listaRetorno.php?perfil=teste"
    width="100%"
    height="100%"
    frameborder="0"
    scrolling="no">
</iframe>

Y server page that returns in the above code iframe:

// $perfil = $_POST['perfil'];  
$perfil = $_GET['perfil'];  
echo $perfil;

Probably you will need synchronous responses, so it is best to make the conversation between the two applications through a protocol (ajax preference) with typed return (for example json).

Because Voce could not for example make a simple $.post('other server') and catch the result ?

  • he probably didn’t get it with ajax because of the Cors, which is a security issue.

  • still there should be better possibilities than an iframe, of course, depending on the level of capacity of changes it has on the server

  • I did not say there is, even via Ajax if solving the Cors will work, I just answer your question "Because Voce could not for example make a simple" with a probability. Being different servers the problem is usually Cors, so the server you tried to access should allow this.
