Hey everyone! i want to get some specific parameters from URL. If the url contains id then do this and if the url contains userno then do this and if it didn't contain anything do this. I want to put it in If else statement. the url is like this If it didn't contain anythinghttp://localhost:8080/web/promotions.html If it contains idhttp://localhost:8080/web/promotions.html?id=Food If it contain usernohttp://localhost:8080/web/promotions.html?userno=12 How can i do this?

ajax call and the $_GET array. See:http://www.w3schools.com/php/php_ajax_intro.asp

I am doing it like this

if((location.search=="") ? "" : "userno"){  var get = '';  var userno = getUrlVars()["userno"];  get = 'getpromotions.php?userno='+userno;}else if((location.search=="") ? "" : "id"){   var get = '';  var id = getUrlVars()["id"];  get = 'getpromotions.php?id='+id;}else{  var get = '';  get = 'getpromotions.php';  }

In this only If and Else are working, else if statement is not working..

It's "working", but it's never going to go into that block because the second if statement checks the same condition as the first if statement. Both of them will only execute if location.search is empty, and if it's empty then only the first block will get executed.

So how can i do it ? please tell me..

What exactly are you trying to do with that code? It sounds like you should save the return value of getUrlVars and then check if items in the array are undefined.

I want to check the URL, if the URL contains id then do this, if it contains userno then do this and it didn't contain anything then do this... Can you tell me a different code for doing this??

[justsomeguy]

Save the results and check each one.

var urlVars = getUrlVars();var urlId = '';var urlUserno = '';if (urlVars['id'] != undefined) urlId = urlVars['id'];if (urlVars['userno'] != undefined) urlUserno = urlVars['userno'];

Now you can check the values of urlId and urlUserno to figure out what you want to do.

Just a quick question... is getUrlVars() a user-defined function or of some library? Thanks.

[aneeb]

getUrlVars() is a pre-defined function.
