  You marked the previous one as solved, but then don't say here why it turned out not to be....
  
  Can you tell us?

    Hi John, to be honest I can't remember exactly why it didn't work, unfortunately it just didn't work as hoped. I considered not including the link to the previous question as a) it might confuse people and b) the updated question is worded differently.
    
    I'm not sure if the old question/thread is useful, or if people would prefer to discard the historical stuff and look at the question afresh.
    
    Thanks.

    John Cotton says:

    So why can't you just use the first site_url you come across in a session and stick with that?
    
    ie
    
    

    function get_custom_home_link() {
    
    if( !isset($_SESSION['homelink']) {
    
    $_SESSION['homelink'] = site_url();
    
    }
    
    
    
    return $_SESSION['homelink'];
    
    }

    John Cotton says:

    Sorry, that's missing a bracket:
    
    

    function get_custom_home_link() {
    
    	if( !isset($_SESSION['homelink']) ) {
    
    		$_SESSION['homelink'] = site_url();
    
    	}
    
    
    
    	return $_SESSION['homelink'];
    
    }

    Hi John, just tested your code.
    
    I began on property1 and the homelink URL was property1 - great.
    
    Next, I clicked a hyperlink on property1 to a page on city1 and the homelink URL changed to city1 rather than pointing back to the property1 homepage.

    John Cotton says:

    Are all your sites really on the same domain or have you just written it that way?
    
    If they aren't then my code won't work as it relies on the session variable which, obviously, gets changed when you change domains!
    
    What I don't know (but will try to find out) is whether WordPress does a session reset if you are using the sub-directory approach as you seem to be...

    designbuildtest says:

    Thanks for the speedy responses John.
    
    Yes, all sites are on the same domain.
    
    I'm testing on my local server so URL's for homepages are localhost/property1, localhost/city1 etc.

    John Cotton says:

    Just out of interest, why are you using multi-site?
    
    Wouldn't the SEO be better as domain.com/city1/property1?

  • 01/17/12 5:37am
    
    designbuildtest says:

    It's an Internal site, so no need for SEO. Property details are the focus, rather than the generic city information.

    Hi
    
    $_SESSION definitely works across path-based multi-site installs (at least in version 3.3 on which I've just checked).
    
    Have you actually started the session? You need:
    
    

    session_start();

    
    
    somewhere before the home link code is run (I tend to stick mine at the top of functions.php.

    PS Just tried my code on a path-based multsite and it works for me...:)

    designbuildtest says:

    Hi John, adding
    

    session_start(); 

    
    before the function worked perfectly.
    
    Your very simple solution was exactly what I required.
    
    Thank you.

    Hi John, as noted in Christianto's thread below, I'd like to split the prize value with both yourself and Christianto as both answers worked as I had hoped. I'll vote for the $35 prize money to be split $20 to yourself and $15 to Christianto.
    
    Thanks again

  What if visitor browse from city site to property site?
  do you want to show city site homepage link or property site homepage link?
  
  You need to change homepage address to referring site if visitor browse other site on your network, but not change it if it browse from outside network?

    designbuildtest says:

    Hi Christianto. The chances of a visitor starting their session on a city site and then browsing to a property site are tiny - this scenario can be ignored.
    
    Yes, correct, to your second question. The homepage link doesn't change if the visitor begins their session via an external link from outside the multisite network.
    
    Thanks

    Hello,
    
    have you find your solution?
    if you haven't, please try my code:
    

    
    
    function write_homepage_referer(){
    
    	
    
    	$write_cookie_on_directory = array( '/property1', '/property2', '/property3' );
    
    	
    
    	foreach($write_cookie_on_directory as $check_site){
    
    		// if match set cookie for 1 hour
    
    		if(strpos(get_bloginfo('url'), $check_site)) 
    
    			setcookie("sister_site_referer", get_bloginfo('url'), time() + 3600, COOKIEPATH, COOKIE_DOMAIN, false, false);
    
    	}
    
    }
    
    add_action('init', 'write_homepage_referer');
    
    
    
    
    
    function get_custom_home_link($subdirectories){
    
    	
    
    	$home_url = '';
    
    	$referer = strtolower( $_COOKIE['sister_site_referer'] );
    
    	
    
    	 // If no refferer return curent blog home
    
    	if ($referer == null || $referer == '' || $referer == get_bloginfo('url') ){
    
    		
    
    		return get_bloginfo('url');
    
    	
    
    	} else {
    
    
    
    		$ref = parse_url($referer);
    
    		$this_url = parse_url( get_bloginfo('url') );
    
    
    
    		// if domain same, from outside network
    
    		if( $ref['host'] == $this_url['host'] ) {
    
    			
    
    			foreach($subdirectories as $subdirectory){
    
    				$checkreferer = strpos($_COOKIE['sister_site_referer'], $subdirectory);
    
    				
    
    				if ( isset($_COOKIE['sister_site_referer']) && $checkreferer ){
    
    					$home_url = $_COOKIE['sister_site_referer'];
    
    				} 
    
    			}
    
    			
    
    			if($home_url) 
    
    				return $home_url;
    
    			else
    
    				return get_bloginfo('url');
    
    		
    
    		} else {
    
    			
    
    			return get_bloginfo('url');
    
    			
    
    		}
    
    	}
    
    }

    
    
    as you can see there are array that you can supply with your directory path on cookie creation function
    

    $write_cookie_on_directory = array( '/property1', '/property2', '/property3' );

    
    
    and called it by passing same array of your site directory path
    

    echo get_custom_home_link( array( '/property1', '/property2', '/property3' ) );

    
    
    
    Hope this help
