If you need custom JavaScripts, Jscripts, PHP scripts //or custom behaviors for DreamweaverMX, go to www.brettbrewer.com and send me a message. // //BEFORE YOU INSTALL THIS SCRIPT: //Please note, that in order for this script to work, users must arrive //at your page via a standard HTTP web link of some sort. You cannot use this script on pages //that utilize a javascript navigation menu such as a form-based pulldown menus that //use "onChange" events to trigger javascript navigation functions //or other types of javascript navigation methods. However, this should work fine on sites that use //dynamic menus that create real web links. To tell if your navigation uses standard links //simply right-click (option-click for Mac users) on one of your menu links and select "Open Link in New Window". //If the link fails, chances are pretty good that this script won't work for you. Otherwise, read on. // // // //STEP 1: Set the following variable equal to your SoftCart directory. This should be identical to the value // in your sidedoor.js file. Make sure to include the leading slash to specify the path from your root // web directory to the softcart executable. // var SCPath = "/cgi-local/SoftCart.100.exe"; // //STEP 2: Set the following variable equal to the name of your store (same as name used in your store administrator). // var config = "scstore"; // //STEP 3: Specify the rootPath variable as your complete domain in format "www.yourdomain.com" // var rootPath = "www.danielpendley.com"; // //STEP 4: //Here we define a regular expression so we can later search for a referring URL //that looks like a valid SoftCart URL. It just defines a pattern to look for //that will identify your SCPath. You basically just enclose your SCPath in a pair //of slashes and then preceed any other slashes or periods with a backward slash. //The trailing "i" makes it a case-insensitive search.If you //can't figure this out, just contact me via the web address above and I'll be happy to send you one for your //particular SCpath. Here are some regular expression examples for various typical SCPaths: // //if your SCPath = "/cgi-local/SoftCart.exe" then your //var myRE = /\/cgi-local\/SoftCart\.exe/i; // //if your SCPath = "/cgi-bin/SoftCart.exe" then your //var myRE = /\/cgi-bin\/SoftCart\.exe/i; // var myRE = /\/cgi-local\/SoftCart\.100\.exe/i; // //STEP 5: Save this script in the root web directory of your site. // //STEP 6: Add the following line to the section of each of your non-SoftCart pages. // // //DO NOT TOUCH ANYTHING BELOW THIS LINE UNLESS YOU KNOW YOUR JAVASCRIPT. //______________________________________________________________________ var cartID; var theArray; var referringURL = document.referrer; //Here, we make sure there actually is a referring address. If the user enters the page through a form //selection menu or a javascript "Jump Menu" such as those in Dreamweaver, this will not work because //there is no referrer set in such a link. If you use this script on such a page, you must add some //javascript to the jump menu to set the referrer equal to whatever you need if(referringURL!=""){ //Then we verify that the referring page URL contained a Softcart ID and if so, we extract the cartID //which we assume is the third parameter delimited by a "+". This is where we need that regular expression //we defined earlier. It basically says, if we see the SoftCart directory and .exe file in our referring URL //and the url does not start with the word "file" and there is a "?" in the URL denoting URL parameters which will //hopefully contain a cart id, then we go ahead and mess with the URL. if((referringURL.search(myRE) != -1) && (referringURL.substring(0,4) != "file") && ( referringURL.indexOf("?") != -1)){ //Split the referring URL into its components and save them in an array called "theArray". theArray=referringURL.split("+"); //The cartID should hopefully be the third string in the zero-based array. cartID=theArray[2]; //Here we replace the current URL with a URL that contains the cartID as a parameter. //If you have additional URL parameters to preserve, then chances are, you //can figure out how to modify this script to preserve them too. window.location.replace(location.pathname + "?cartID=" + cartID); } //Now we check to see if the referring URL contains a preserved cartID parameter from another non-SoftCart page //Note that this time, we actually search for a literal string "cartID" rather than a regular expression. Since //SoftCart doesn't use a URL parameter called cartID within the store, we know that if the referrer has the word //"cartID" in the URL, then it must be a preserved cart from another non-SoftCart page. Not that it matters. else if((referringURL.search("cartID") != -1) && (referringURL.substring(0,4) != "file") && ( referringURL.indexOf("?") != -1)){ //Split the referring URL into its components, saving them in theArray. //Since we are just splitting it at the beginning of the URL parameters, //this should preserve as many parameters as there happen to be. In fact, you could //get rid of the first two conditions in the if clause above and just look for the "?" //denoting the the presence of any URL parameters at all. We don't really care what they are. theArray=referringURL.split("?"); //Now all the URL parameters should be in the second element of the zero-based array, so we //just add them all back. The fact that we are calling this variable cartID here is of no //consequence and probably obscures the logic a bit. cartID=theArray[1]; //Replace the current URL with a URL that contains the rescued URL parameters. window.location.replace(location.pathname + "?" + cartID); } } /*example of a refferring URL: http://www.realestate-school.com/cgi-local/SoftCart.100.exe/online-store/scstore/scpages/showcart.html?P+scstore+qzqh5275ffc420c4+1044974841 */ // actual URL begins at position 7
