问题 I am using codeigniter 2.1.4 and I have set $config['url_suffix'] = ".html"; It's working fine with out any trouble.

问题 I am trying to populate a dropdown list from database. In my view file I have the following code $batch= $query ['batch']; // I pull this data from a separate model echo form_dropdown('shirts', $options, $batch); Now the drop down list is populating data fine but the problem is I don't get the value-"$batch" automatically selected when the page loads.
