[Closed] Codeigniter Validation Question

[eluser]riwakawd[/eluser]
I have the general codeigniter validation setup, but I am trying to add bootstrap input has error and has success.

I have got the bootstrap has-error working. But trying to get it so i input is filed in correct it will show has-succes so input will turn green

Code:

<div class="form-group &lt;?php if(validation_errors()) echo 'has-error'; {else} echo 'has-success'; ?&gt; ">
<label for="input-username">&lt;?php echo $entry_username;?&gt;</label>
&lt;input type="text" name="username" value="&lt;?php echo set_value('username');?&gt;" placeholder="&lt;?php echo $entry_username;?&gt;" id="input-username" class="form-control" /&gt;
</div>

has-success not working.
