Trying to understand forms

Hi all,

I feel I am so close to getting my first form to work, I just cannot understand how to process what is setup.  I have the following:

PHP Code:

<?php echo form_open('login/settings'); ?>
        <?php echo form_label('Google Analytics :'); ?>
        <?php echo form_input(array('id' => 'google-analytics', 'name' => 'google-analytics', 'class' => 'form-control', 'value' => $google->setting_value)); ?><br />
        <?php echo form_label('Hotjar Analytics :'); ?>
        <?php echo form_input(array('id' => 'hotjar-analytics', 'name' => 'hotjar-analytics', 'class' => 'form-control', 'value' => $hotjar->setting_value)); ?>
        <br /><?php echo form_submit(array('id' => 'submit', 'value' => 'Submit', 'class' => 'btn btn-default8')); ?>
        <?php echo form_close(); ?>

I get no errors and when I hit submit it flashes the screen so I believe it's working but I just cannot figure out how to get it to process what is in this form, I have been looking through the docs and its just not sinking in.

Can anyone help please?

Thanks,
Doomie
