current url

slimjim

Hello, i hope someone can help !!

How would i write code so that if just so much of the the first part of the url changes, like let say http://www.mysite.com/join which would be only a small part of what would be in address bar. If say so many chars of the begining of the current url changes. Have a popup happen so that I may write some of the entire url info to a database.

ANy suggestions on this ?

Now i am assuming it would also need maybe javascript, on account of me needing a popup to happen.

Here's a way to get the current url:

$url_string = 'http://' . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];

Yes but I only want part of the current url. Here is sorta what I am thinking so far.

// get host name from URL
preg_match("/^(http:\/\/)?([^\/]+)/i",
   "http://www.mysite.com", $matches);
$host = $matches[2];

// get last two segments of host name
if preg_match("/[^\.\/]+\.[^\.\/]+$/", $host, $matches);
{
if nothing changes then nothing will happen
}
else if{
Here is where if the url changes i want a popup to happen
}

Of course only getting problems, cause it seems i am not doing the if statement correct. Any Ideas Please....

Well, it's just a matter of being creative with string functions:

$url_string = 'http://' . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];
$parse_url = parse_url($url_string);
$host = $parse_url['host'];
$host_arr = explode('.', $host);
$parts = count($host_arr);
$new_host = $host_arr[$parts - 2] . '.' . $host_arr[$parts - 1];

parse_url

OK that breaks it down to mysite.com which is what I want.
But, how do i make it so that if that part of the url changes, do something ..... else do nothing if it doesn't change..

if ($new_host != $host) {
    // do something
} else {
    // do something else or nothing
}

$url_string = 'http://' . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI']; 
$parse_url = parse_url($url_string); 
$host = $parse_url['host']; 
$host_arr = explode('.', $host); 
$parts = count($host_arr); 
$new_host = $host_arr[$parts - 2] . '.' . $host_arr[$parts - 1]; 

if ($new_host != $host){ 
    //echo " ok if this url has not changed do nothing"; 
} 
else{ 

//echo " ok if it did then trigger onunload event"; 
} 
/* 
Ok if current window is no longer the same $new_host, such as if a frame breaker happen 
or if a person closed current window, then it needs to trigger the onunload event, that would popup a php page. 
*/

reason it needs to work like this is, because i will need to be able to click links in the frame and by just using a onunload event it seems i get a popup everytime i click a link, so now i am resorting to this method.

So if you know php and javascript, could use a little help in figuring this out.
Right now if I close a window or change urls, of course nothing happens, so now need to get this to work with maybe a onunload or something, but still be able to click link in the frame, but if i would to close window or change url totally, then i need a page to pop up .

You'd better find someone with better knowledge of javascript (and frames) than I have. Glad to have helped so far, though.

BTW, you've got the if/else switched. "if ($new_host != $host)" will be true if the url is changed.
