Have you tried

Code:
if($this->validation->error_string != '')

the code ive posted already checks for validation errors and echoes the validation error.
what i wanted is that when there is a validation error,the submit button should be enabled.

You could try something like

Code:
<div style="font: 12px normal Verdana;color:red;">

&lt;?php

$disabled = "disabled";

if($this->validation->error_string){

echo $this->validation->error_string;

$disabled = "";

}

?&gt;

</div>

and on your button

Code:
disabled = &lt;?php echo $disabled; ?&gt;

how do you disable it? I believe you used xajax but i'm not familiar with it.

I'm a jquery user and the way i do something like this is to change the class.

Code:
// view

&lt;input type="submit" class="&lt;?php echo $buttonclass; ?&gt;" value="send"&gt;

// js 

$(function(){

   $('.enable:disabled').each(function(){

      this.disabled = false;

    });

  $('.disable:enabled').each(function(){

      this.disabled = true;

    });

});

I hope this can help you

Seeing this code the function is not going to to be triggered because there is no trigger for it (oncomplete, onload).
You could try

Code:
echo "&lt;script&gt;enable_button();&lt;/script&gt;";

You should check the xajax documentation to see if you can attach the enable_button function to the oncomplete event that is how it works in jquery.

I don't know if you would consider this but instead of enable/disable the button why don't you hide/show the button? This can be done using only php.

should work with:

Code:
echo "&lt;script type=\"text/javascript\"&gt;enable_button()&lt;/script&gt;"
