How to create a blogger landing page which will redirect to other pages based on the query string?

This article will help to know how to access and check the query string of a blogger blog page and redirect to other pages based on the query string.

Blogger allows passing of query string and we can access the parameters using Javascript.

Let me expain this based on a blogger blogspot blog

Here is my blog address http://www.crozoom.com

Here I had added some referrer links to some external websites like flipkart.com

Earlier I linked directly to flipkart links from my blog. Now i changed this so that the referral links are directed to a landing page in the blog and from there based on the query string, I am redirecting to the external websites....


HOW REDIRECTION WORKS

Here is how it works:

I had created a post named campaign ( http://www.crozoom.com/2013/01/campaign.html Click here to view the demo working )

When calling this page I passed the referrer identifiers as query string, like example given below

http://www.crozoom.com/2013/01/campaign.html?site=vo&key=IT+Jobs

On the POST body, I had added JS function to get the query string values, check it and based on that user is redirected to corresponding external website.

Before adding JS code , you can place some redirect message warnings for the user.

Do the following steps:

Step 1: Click on the "New Post" button on blogger admin

step 2: Place the following code and save the post as campaign.html (use your own post name)

---------------------
---------------------
Place here Your user redirection
warning message ...
---------------------
---------------------

<script>
function get_QryStr ( qry ) {

var arr_qry_str;
var match,
replace_plus = /\+/g, // Regex for replacing addition symbol with a space
search = /([^&=]+)=?([^&]*)/g,
decode = function (s) { return decodeURIComponent(s.replace(replace_plus, " ")); },
query = window.location.search.substring(1);
//alert(query);

arr_qry_str = {};
while (match = search.exec(query))
arr_qry_str[decode(match[1])] = decode(match[2]);

return( arr_qry_str[my_param] );
}

var site = get_QryStr("site");
var key = get_QryStr("key");
var link = get_QryStr("link");

if( site=="" )
site = "vo"; // default identifier

var redirect_link="http://www.vacanciesonline.in/";

if( site == "vo" ){
redirect_link="http://www.vacanciesonline.in/";
if( key!="" ){
redirect_link="http://www.vacanciesonline.in/search/label/"+key+"?max-results=8";
}
}


if( site == "fk" ){
redirect_link="http://www.flipkart.com/";
if( key!="" ){
redirect_link="http://www.flipkart.com/search?q="+key+"";
}

if( link!="" ){
if( link == "electronic-offers" )
redirect_link="http://www.flipkart.com/offers/electronics?&icmpid=foz_menu_electronics";
}
}

document.write("<a href='"+redirect_link+"' rel='nofollow' ><b style='color:red'>CLICK HERE TO VISIT</b></a>");

document.location.href=redirect_link;

</script>

The above code will check the query string and based on its values, will redirect to 2 other websites.

Same thing you do with a meta tag level redirection by checking the url

Hope this helps:)
