Hello

My code checks the username entered in a PHP file. The jQuery then displays if the username is taken or not.

I have added code to the PHP file to also check if the username is below 3 characters or over 16 characters. How do I add another if within this code to display the correct result?

I know the code will be

2.  if(d=='under'){
3.     $("#usernamemessage").html("Username not long enough");
4.    }

But don't know how to implement it into the exsisting code.

Thanks

2. <input type="text" id="txtusername">
3. <input type="button" id="button" onclick="buttonFunction()">
4. <span id="usernamemessage"></span>
5. <script>
6. $(document).ready(function(){
7.  v=$("#txtusername");
8. s=$("#button");
9.  s.bind('click',function(){
10.   $.post('check.php',{user:v.val().toLowerCase()},function(d){
11.    if(d=='available'){
12.     $("#usernamemessage").html("<span style='color:green;'>Username is available</span>");
13.    }else{
14.     $("#usernamemessage").html("<span style='color:red;'>Username is not available</span>");
15.    }
16.   });
17.  });
