将朋友GET ID传递给另一个页面

Question

I have asked this question before but I couldn't understand the answer maybe because it didn't work for me.

I have a developed a chat application. Once a user submits using keyup, it works well i.e inserted into database and also selected just fine and the message is even displayed. The page being refreshed by javascript is load.php which has php code doing the selection like this;

SELECT * FROM chat WHERE sender_id=$_SESSION['id']

This is working just fine. But when I change it to

SELECT * FROM chat WHERE sender_id=$_SESSION['id'] AND receipent_id=$_GET['id']

it is not working simply because the $_GET['id'] of a selected member in the home page is not being passed to the load.php which is being refreshed by javascript every .....milliseconds so that online messages of the session id and the selected member should show in the message display. I refresh the load.php using this code on the home page;

function refresh(){ 
    setTimeout (function(){ 
        $('#message').load('load.php'); 
        refresh(); 
    }, 2000);
} 

working just fine.

Now this load.php must select for me messages only for the member selected in the home page. So how can I have this members' id passed on to this load.php on selecting from database?

Will be so grateful for your help programmers.

Answer 1

If you want to pass $_GET['id'] value try to add in your function this value

function refresh(){ setTimeout (function(){ 
    $('#message').load('load.php?id=<?php echo $_GET['id']; ?>');
    refresh(); }, 2000);
}

Then load.php will have get value
