[RESOLVED] make variable from ajax-called php doc global?
(this is my first post; I'm inexperienced in both ajax and javascript (but learning!), so I'm sorry if I screwed anything up and if you need more/less info, let me know; thanks!)
Ok, so I'm trying to get a variable called $active_name to display in index.php as 42. It's changed to that in active_players.php when active_players.php is 'opened' via ajax. That change only stays in active_players.php. When a button is clicked in it, send_invite() is called, which, not being part of active_players.php, has $active_name remain as 24.
I've excerpted out just the parts that I think you will need to find my error. Please let me know if more information is needed.
PHP Code:
//inside index.php
<?php
$active_name = "24"; //if this is taken out, the variable, 'name' in send_invite() ends up being undefined
?>
function reset_active_list()
{
loadXMLDoc("active_players.php",function()
{
if (xmlhttp.readyState == 4 && xmlhttp.status==200)
{
document.getElementById("active_box").innerHTML = xmlhttp.responseText;
}
});
act_li_rst = setTimeout("reset_active_list()",1000);
}
function send_invite()
{
name = '<? echo $active_name; ?>'; //I want this to be 42, but it's 24
loadXMLDoc("send_invite.php?name="+name,function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("top").innerHTML = xmlhttp.responseText;
}
});
}
PHP Code:
//inside 'active_players.php'
<?php
$active_name = "42";//I would like this to become global in index.php
echo $active_name;//it's 42, here of course.
echo "<input type='button' onclick='send_invite()' value='test'/>";
?>
