So here's the thing, i've done the tutorial thing on CI, i have already done some modification in .htaccess to remove index.php in URL, in these case, when viewing records index.php doesn't appear, but when i try to create a new record, index.php suddenly appeared, i'm confused as to why it appeared, i've already done something to .htaccess like so,
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php/$0 [PT,L]
Here are some screenies,

EDIT I just followed what they ask me to do on their user guide.
Create a news item
<?php echo validation_errors(); ?>
<?php echo form_open('sample_controller/sample_create') ?>
<label for="title">Title</label>
<input type="input" name="title" /><br />
<label for="text">Text</label> <textarea name="text"></textarea><br/>
<input type="submit" name="submit" value="Create news item" />
</form>
