Adding code before and after a link

[shanet]

Is thier any where you can edit so that a certain piece of code is added to all out going links? Example:

http://www.yoursite.com/go.php?id=1 will take you to yahoo.com becuase :id=1 was submitted as www.yahoo.com

Now lets say you want to add like a tracking code so that when the link on your site is clicked would produce the following results:

when this link is clicked http://www.yoursite.com/go.php?id=1 would produce these results /beginingcode=www.yahoo.com&endcode

Basically you want /beginingcode and endcode added to all the out links that are clicked without having to edit all the links in the database. Confused yet? =)

can you be a little more specific: what is begincode and endcode?

Are you talking about some click counter code?

[shanet]

it is not a counter code but a link skimming code. where as i can set a url to send a certain % to other sites or a certain % to the actual url.

if a link is submitted as http://www.yahoo.com i want it so that when it is clicked it would produce the result:

/cgi-bin/skim/c.cgi?url=http://www.yahoo.com&p=70

basically that would call the cgi script i have on my server and send 70% of clicks to gallery and the other 30% where ever I have my other script point it =)

I basically need it so that /cgi-bin/skim/c.cgi?url= is automatically placed in front of the submitted url and &p=70 is placed at the back of the url on click.

thanks!

Do you trying to passing variables to target link?
It could be useful if you want to use 3rd party counter, ads tracking, etc.

To do this you need to hack go.php and link.class.php
Here is the direction:
1. Pass the variables to go.php
2. You need to change this code in go.php to receive your variables line 40-47

  if(!in_array($id,$ses_links) || count($ses_links)==0) {
    $_SESSION['indexu_session_links'] = $_SESSION['indexu_session_links']."$id;";
    
    $links_obj->Go($id,true,$var1,$var2);
	}
	else {
	  $links_obj->Go($id,false,$var1,$var2);
	}

3. Edit /lib/link.class.php function Go() line 2836, to receive your var

function Go($id,$count=true,$var1,$var2) {

Line 2875

$url = $var1.$url.$var2;
header("Location: $url");

Do not try it yet, but logically work

[shanet]

where would i define what $var1,$var2 is? so it knows that
$var1 produces /cgi-bin/skim/c.cgi?url=
$var2 produces &p=70

Thanks!

if it is the same for EVERY link, then

DO NOT change go.php

  if(!in_array($id,$ses_links) || count($ses_links)==0) {
    $_SESSION['indexu_session_links'] = $_SESSION['indexu_session_links']."$id;";
    
    $links_obj->Go($id,true);
	}
	else {
	  $links_obj->Go($id,false);
	}

and change the go function in link.class.php

  function Go($id,$count=true) {
		
		// get current hits
    $query = "select hits, url from $this->table_name where link_id=$id";
    $result = $this->db_connect->Execute($query);
    $url = $result->Fields("url");
    $hits = $result->Fields("hits");

		if($count) {
      // update hits
      $query = "update $this->table_name set hits = ($hits + 1) where link_id = $id";
      $result = $this->db_connect->Execute($query);
    		
		}
$url = "/cgi-bin/skim/c.cgi?url=".$url."&p=70";
    header("Location: $url");
  }

If $var1, $var2 change from link to link, then you will need to do what dody suggests and also, probably add 2 fields to your database and put the results of the query in go.php in as variables to calling the go function.

[dody]

Yes, good esm. You have better and simpler modification.

[esm]

but only if it is the same for EVERY link.

Otherwise, he would probably need to do what you suggest. Plus, somehow identify what link got which set of counter codes.
